Factors shorten the life of Raymond mill

Raymond Mill is a large milling machine, we all know the body type due Raymond Mill huge range of parts, so the price is not low Raymond mill. Users in the Raymond mill price is high, it is more concerned about the Raymond mill longevity of. So a Raymond mill life in the end how long it is, Raymond mill life and what factors related to it. On Hai Zhuoya mining machinery tell you that in fact Raymond mill life is actually a lot, if the majority of users usually use the Raymond mill can pay attention to strengthen the maintenance of Raymond mill, Raymond mill can be used more for a long time.

Factors that affect the life of Raymond mill can be divided into many, the Hai Zhuoya mining machinery simply summarized into two categories: one is the Raymond mill equipment itself of factors, one is the late human operational factors.

Raymond manufacturer of quality factors determine the quality of equipment Raymond mill, Raymond mill manufacturers if using thinner materials and poor technology, quality milling equipment that produced the affirmation of mill's life has a great influence. Raymond mill is specialized in processing high hardness of the material, if the quality of Raymond mill itself, but off, poor quality steel, dislocation accessories, fasteners and other issues is not strong, then the life of Raymond machine is certainly not for a long time, so the time to buy the machine according to the actual needs to shop around, choose the highest quality products, the best manufacturers, to visit the factory if the words better.

Raymond mill is a large mining machinery, professional operators need to operate on the professional level of technical operations personnel requirements are relatively high, correct daily operation, maintenance, maintenance and other factors that are important life decisions Raymond machine factor. Wrong mode of operation may result in Raymond mill device against damage will shorten the life of Raymond mill.

How to produce a good stone？

Stone grain type is in many cases have strict rules, such as paving stones, ore particle size of decorative stone is defined, then the factors affecting the stone production line of stone size, what is it. Our daily production and life of the stone is usually made from sand and gravel production line process, that part of the decision of stone production line stone size, then we know which particular aspects affecting the intensity of it gravel, mining machinery on Hai Zhuoya a simple analysis of the main factors for everyone under the influence of sand stone production line granularity

Stone production line generally consists of feeding, crushing, medium crushing, screening, back to the material crushing, screening and other sectors together again, of which the sand and gravel production line feeder links may be isolated part of the natural fines, but the amount It is small, the impact of the flakiness content is small.

Although jaw crusher works belong to squeeze broken, gravel will have some flakiness content, but because it is crushing, not directly on the vibrating screen sieves, it will not affect the gravel the flakiness content. After the sand is coarse crushed gravel crushing the link at this time we have a lot of optional equipment, cone crusher, impact crusher, fine broken jaw, and impact crusher is due to the impact crusher impact plus, although produced ore is very low flakiness content, grain shape is good, but because it is the crusher head-crushing mode, crushing some of the soft rock during good behavior, but a case of granite, basalt rock hardness is relatively large will damage the machine, it will result in gravel granularity bad phenomenon.

How to produce a good rock grain type, we need to further shaping, where the user can get a good grain type of stone in two ways, both of which are: (1) the coarse crushing equipment selection part of the cone, out of stone unity into the shaping machine shaping; (2) is a stone crushing production line in selecting the appropriate link in the cone, after screening by the material back into the shaping machine shaping.

what are Jaw crusher lubrication process need to pay attention ?

It is well known jaw crusher and cone crusher stone crusher equipment is a common device in the market has a very wide range of applications, jaw crusher is a major crushing equipment, and cone crusher is common fine crushing equipment, when customers select and purchase equipment for crushing stone crushing plant in the process that there are many factors that should be considered, the common factor is four rock types, rock feed size, desired output size scope and crushing capacity per hour, which requires a good choice, and we know the strength, hardness, the product feed and output, yield and other factors after the rock, you can choose a suitable crusher equipment based on the above factors.

In the jaw crusher and cone crusher during use, crusher equipment maintenance and repair knowledge is also very important, first of all routine maintenance jaw crusher today to brief speech lubricating parts, lubrication parts It can be easily and reliably serve the needs of member crusher lubricating (machine has four parts of lubricant required: four shaft bearings). Second, in the process of lubrication, note the following:

Impact Crusher is mainly used in metallurgy, chemicals, building materials, utilities and other materials often need to move processing operations, especially for highways, railways, hydropower engineering and other stone work flow, according to the type of processing of raw materials, different sizes and finished material requirements using a variety of configurations. China's current mobile impact crusher station and more used in the demolition of urban garbage treatment project construction, construction waste will be recycled aggregate crushing and screening become several different sizes and rules, is the realization of China's construction waste resource recycling project Foundation.

Crusher main purpose
Impact crusher can process the materials side length of 100-500 mm, a compressive strength of up to 350 MPa, with broken than large, broken materials showed cube particles after the advantages. Widely used in building materials, ore crushing, railway, highway, energy, transportation, energy, cement, mining, chemical and other industries used in finely divided materials. Its particle size can be adjusted discharge, broken specifications diversification.
Crusher five advantages
Impact Crusher is named according to the principle, namely the use of the principle of impact crusher for crushing material, is a more than fine jaw crusher crusher equipment, stone production line is mainly used for crushing operations, and jaw crusher crushing cooperation. Crusher has a performance advantage in the following five aspects crushing process.

First, the material crusher large wet process more effective, effectively prevent the material clogging.
In dealing with excessive moisture content of materials, crusher feed chute and the back plate can be equipped with heating means, to prevent the adhesive material. Crusher shall not be equipped with the bottom of the sieve can effectively prevent clogging.

Second, the crusher is suitable hardness of the material more widely.
Crusher board hammer mechanical clamping structure firmly fixed on the rotor, with a great moment of inertia when the rotation with the rotor. With respect to the hammer crusher (hammer was hanging state), rotor crusher has a greater momentum, crushing harder to adapt to the material, while their low power consumption.

Third, you can adjust the particle size convenient and flexible, wide adjustment range

Lash adjuster can be adjusted by mechanical or hydraulic, hydraulic system can be easily adjusted by an operator or fortune-place control systems to complete the adjustment of the gap.

Fourth, the wear and tear of wearing parts small metal high utilization
Impact rock breaking machine board hammer wear only appear in the Looking material side. When the rotor speed is normal, the feed will drop to the plate hammer surface (of attack), hammer the back and side panels are not being worn. Even Looking material this side rarely wear. And the bottom of the grinding rod is also very easy to replace. Crusher hammer metal utilization can be as high as 45% -48%.

V. crusher spare parts easy to replace, a corresponding reduction in maintenance costs
Crusher installation on the rotor hammer plate only six, with a special tool designed to easily replace plate hammer, hammer replace a board just one shift time.

Construction waste recycling equipment

With the accelerating process of urbanization, urban construction waste generation and discharge the number is growing rapidly. People enjoy urban civilization, it is also subjected to the annoyance of municipal waste, construction waste where it occupies a large proportion, about 30% to 40% of the total waste, according to the information, based on a brick structure construction materials and full cast structure and frame structure and other buildings losses rough statistics, during the construction of every ten thousand square meters of construction, only construction waste will produce 500 to 600 tons. If Click to estimates, China's annual construction of the building and construction waste generated only discharged to more than 100 million tons, with construction waste building renovation, demolition, building materials industry generated number will reach hundreds of millions of t. So how to deal with and take advantage of a growing number of construction waste has become an important subject of government departments and construction waste at all levels are facing.
Many of the construction waste by sorting waste, after removing or crushed, mostly as re-use of renewable resources, such as scrap steel, scrap wire, scrap wire and various accessories, such as scrap metal, after sorting, concentration, again melted down, it can then processing into a variety of steel products; bamboo wood waste can be used to manufacture artificial wood; after brick, stone, concrete and other waste by crushing. Therefore, we in the construction waste disposal, must adhere to the comprehensive utilization.

(Mobile Crusher) allows construction waste waste to treasure. Mostly construction waste solid waste, usually during the construction or repair of old buildings, demolition process produces. Content of different types of building structures generated garbage despite the various components of different, but the basic composition is the same, mainly from the soil, sediment, scattered mortar and concrete, concrete and masonry chisel tick fragments generated, piling cut under reinforced concrete pile head, metal, bamboo wood, waste generated decoration, packaging materials and other wastes, of which, the use of abandoned buildings and abandoned concrete masonry production aggregate thickness can be used to produce the corresponding concrete, mortar or prepared intensity level such as blocks, panels, tiles and other building materials; from waste brick and tile production aggregate, can be used for the production of recycled brick, block, wall, floor tiles and other building materials, construction waste reduction have realized quantization, recycling, saving natural resources, protecting the environment and other advantages, and has a high economic value.
Because construction waste piled more concentrated, the venue is limited, and traffic is not very convenient, suggested the use of mobile crushing station. The first mobile crushing and screening equipment for the Commonwealth, a variety of large-scale multi-stage crushing bulk materials. Also mobile crushing station equipment, small footprint, the device flexible and convenient, mobile, can save a lot of infrastructure and relocation expenses; materials can be crushed on site without having to re-crushed material transported from the scene, and with the surface mining of raw materials advance move, thereby significantly reduce the cost of shipping materials. Mobile crusher station flexible configuration, according to the actual site design modifications or special mobile crushing station, ideal for construction waste crushing.
According to the manufacturing process can be divided into crawler mobile crushing station and tire mobile crusher station. Mobile crushing station has flexibility, mobility, and can save a lot of infrastructure and relocation expenses, etc., capable of crushing the material on site, and promote the mining of raw materials with the surface is moved, thereby significantly reduce the cost of shipping materials.

How do lubrication cone crusher?

Cone crusher lubrication of a direct impact on the health of the machine parts and the length of life, it can reduce friction and wear, but also can play a cooling, to prevent corrosion and flushing action. Therefore we need to do lubrication crusher.

Cone crusher can be used for centralized lubrication cycle, reasonable lubrication technology directly affect economic performance cone crusher. Lubricating oil lubrication oil station of two routes into the crusher, all the way through the frame bottom bracket cover into the hole into the lower body lubricated disc, bushings, thrust bearing bushing, and by the middle of the spindle bearing bore to bowl and bevel gear, bevel small gear lower part of the body bore back into the tank, the other way into the pipe rack shaft, drive shaft bearing lubrication at both ends, respectively, back into the tank from the creel dust cover and the lower part of the small bevel gear. In order to ensure good lubrication, can strengthen the main
lubrication management from the following aspects:
 1) Depending on the season climate, choose a different lubricants.

2) oil pressure is generally controlled at 0.08 ~ 0.2MPa, too large or too small will affect lubrication.

3) In order to ensure the crusher during operation get adequate lubrication, lubrication system and crusher electric chain, oil pump must be open before starting the machine, otherwise it will not start the motor when the hydraulic pump is stopped or reduced to 0.05MPa, are send a signal to stop the motor running to ensure that the parts are not damaged.

4) Due to mechanical wear and tear during operation generates a small amount of residue and dust from entering, so that the lubricating oil slowly dirty, oil qualitative change bad. To this end, the timing of the lubrication oil station cleaning, oil change 3 to 4 months time.

5) timely start cooling means. Cooling device can be used at any time when necessary to start to control the oil temperature is below 50 ℃.

6) water to eliminate dust and dirt from entering lubricants. If lubricating oil containing excessive ash and moisture, it will greatly reduce the lubricating effect, affect the performance of parts of life and machines. To prevent dust from entering, crusher dust seal means provided by the free end of the dust-bowl-shaped ring is inserted in the annular ditch, and use it to block the dust into the water and with the water discharge, also installed on the outside of the gutter rubber band with a layer of dust, dust it with a bowl-shaped stopper ring dust exposure play a role in isolation. In order to prevent dust and water along the periphery of the bowl-shaped bearing seat inflow lubrication system, in addition to strictly control the amount of water to the outside, but also in the periphery of the bearing seat plus welding circle downward sloping impermeable plate, so the overflow from the ring ditch impermeable to water was blocked plate to the outside of the body, with the ore discharge.

On the ball mill working principle and application

Ball Mill works:
The ball mill is a horizontal cylinder rotating device, outer gear, the two positions, lattice-type ball mill. Material from the feed device evenly into the mill first warehouse into the compound by the air shaft spiral, the warehouse there are ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height after the fall, have severe impact on the material and abrasive. Material in the first position to reach coarse grinding, through the single-compartment plate into the second warehouse, the warehouse lined with flat lining, steel ball inside, the material further grinding. Powder is discharged through the discharge grate plate to complete the grinding operation.
Shanhai Joyal in mass production at the same time, to improve the mill production were studied system. Generally speaking, the direct way to improve mill output has 3 kinds:
1. Plus former mill set crushing machine;
2. Improved ball mill grinding system, improve grinding efficiency;
 3. Plus home high efficiency separator.
 Mill use and the use of:
Ball is the material after being broken, and then smash the key equipment. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metals and glass ceramics and other production industries of all kinds of ores and other grind-able materials can be dry or wet grinding.
Ball mill beneficiation of Use:
Processing equipment - ore mined first by the initial jaw crusher broken, after crushing to a reasonable degree of fineness through the hoist to the mining machine evenly into the ball mill, the ball mill for ore crushing, grinding. After the development of mill ore fines into the next process: classification. Spiral classifier means of different proportion of solid particles in the liquid often the speed of different principles, the mixture of ore grading.
Ball mill aerated concrete equipment in use:
Fly ash (or sand, stone dust) by the electromagnetic vibrating feeder, belt conveyor into the mill, fly ash (or sand, stone dust) with fly ash ground after the pump to the slurry tank storage, respectively.
 Lime by the electromagnetic vibrating feeder, belt conveyor into the jaw crusher crushing, crushed lime by the bucket elevator into the lime storage bin, and then by a screw conveyor into the mill, after the materials are finely ground screw conveyor, bucket elevator into the powder ingredients compartment.
