Two rules for the maintenance of sand making machines

Construction waste after the broken concrete particles, bricks, stone fragments and sand particles, different particle size is not the same application. We can according to the customer's request, the construction waste broken sieve to different specifications. Concrete particles can be used for unlimited roadbed, agricultural and woodland roads, pedestrian and bike lanes and concrete; brick, stone fragments or sand particles can be used for sports venues, gardens and scenic spots of stone, road grassroots and so on.

The use of construction waste disposal equipment to deal with construction waste, on the one hand to solve a large number of concrete waste disposal and the resulting negative impact on the environment, while saving a lot of clean-up costs; the other hand, can also reduce the exploitation of natural gravel. Our construction of the building garbage collection system set screening, broken, iron, dust as a whole, with sound, reduction and resource management and other characteristics, to meet the 40 to 300 tons per hour of construction waste disposal capacity The
Construction waste system is divided into fixed and mobile, fixed crushing station requires a specific site, the need for transport waste to the crushing station after the crushing operations. The mobile crusher station integrates all crushing and screening equipment into one or two wheeled live crawler platforms, which can be flexibly drawn to the required site for crushing operations.

The introduction of the mobile crusher eliminates the cumbersome steel frame structure and foundation construction, saving a lot of time.Mobile crushing station have reliable operation, easy operation, energy efficient features. Especially the mobility is very good, with the raw material or construction site together, and can be a variety of combinations to meet the needs of different materials.

Easy wear parts for sand making machines

Shanghai joyal Mining Machinery is a professional manufacturer of mining machinery and equipment, joayl's ore crusher and sand making machine and ore milling machine and other equipment used in ore processing is popular. Here joayl talk about sand machine machinery. 

Sand making machine is widely used in the production of sand and aggregate, and when sand making machine is working, the parts of the sand crusher is more serious wear and tear.while easy to wear parts of the sand crusher is the key parts, so the easy to wear parts quality of the machine is directly related to the production capacity. But, Which are easy to wear parts of sand making machine？

The wearing parts of sand making machine usually include plate hammer, counter-liner, chassis liner and rotor guard. We should pay attention to the sand for the plate hammer wear failure time is the shortest, and repair costs are relatively high. Therefore, to solve the sand mill wear first to reduce the wear of the plate hammer. The efficient crushing capacity of the sand making machine has a certain influence on the wear of the plate hammer. When using the sand making machine, it is necessary to pay attention to the maintenance of the machine parts in time.

New features of hydraulic cone crusher

Artificial sand and gravel has gradually replaced the natural gravel, with the development of China's economy as well as the development of industry, construction industry and other industries a large number of artificial sand and gravel demand, artificial sand demand increased the production of artificial sand and gravel production machinery Equipment development, today Shanghai JOAYL mining machinery,which is a professional manufacturer of mining machinery, talk about the cone crusher in the artificial sand and gravel production in the processing role.

Cone crusher crushing ratio and the machine is simple and easy to operate, today JOYAL are talking about the advantages of the hydraulic cone crusher.Hydraulic cone crusher is added on the basis of the traditional conical increase The hydraulic protection and hydraulic clearance cavity function. Can be said to be a very efficient energy-saving machinery equipment.

In the gravel production line if the broken material mixed with difficult to break the metal, etc., hydraulic cone crusher unique hydraulic protection system will crush the top of the mouth, making difficult to break the material automatically fall out from it, and then fall on their own jobs. This method reduces the wear of the non-crushing material to the hydraulic cone crusher, extending the service life of the hydraulic cone crusher.

Why does the ore crusher need a iron removal device

Ore crusher is a kind of ore for the broken mining machinery and equipment, gravel production line can often use the mechanical equipment is the ore crusher, gravel production line often used in the ore crusher jaw crusher, Impact crusher, hammer crusher and other ore crushing machinery and equipment. Shanghai joyal mining machinery is a professional manufacturer of mining machinery and equipment, and here we talk about why the need to install iron ore crusher device.

Because of its poor use of the environment, dust, coupled with the use of some units to maintain the unit is not in place, often in the operation of a variety of problems, and ore crusher is used to break the ore machinery and equipment, in the usual operation of the Ore crusher wear more serious, so pay attention to the ore crusher to do maintenance.

Ore crusher machinery and equipment to have iron removal device, which can prevent the broken cavity over iron, if frequent over iron, it may cause the ore crusher shaft problem. So in order to protect the ore crusher machinery and equipment, you need to do the ore crusher over iron treatment.

Suggestions of Limestone crusher configuration

Limestone is easy to break the material, one is low hardness (4 to 5), the second is the silicon content is very low. Therefore, the limestone as raw material of the stone factory production costs are much lower. Therefore, the limestone crushing production line we can directly use the jaw broken counterattack break the program, both to get a good stone grain, crusher parts can also have a very long life. Usually, a pair of jaws used for a year or two is very normal.

Another factor we also need to consider, because the limestone is relatively easy to break the performance, the use of broken broken broken will produce more powder. This is due to the impact crusher is the impact of crushing the characteristics of the decision. If the customer's market demand for stone grain is not high, you can use two-stage jaw crusher way to reduce the proportion of powder, but also relatively reduce the cost of some investment. The specific process of scheduling, according to the customer's actual situation after the analysis to determine.



Due to the easy crushing characteristics of limestone, cement plants with limestone as the raw material are usually crushed by a composite crusher. Using composite crusher directly on the limestone head broken, broken after the particle size can reach 10 to 20 mm below. This is broken in order to break the limestone as small as possible to a smaller particle size, regardless of grain problems. At the same time, such a broken way will produce a lot of powder, for the construction of stone-based stone factory, this broken way inappropriate.

If the customer can accept the powder, then the use of a crusher to be able to complete all the crushing operations is also a good choice.

Granite crushing scheme

Granite belongs to a class of materials that are more difficult to break, but is usually slightly more easily broken than basalt. This is because the granite although the hardness is high, but there is a certain brittle. Therefore, the design of the crushing process can be relatively flexible design, if the customer's market price advantage, you can use two broken process program. However, from the long-term production point of view, three broken process is still able to effectively reduce the cost of production methods.

If the customer's market demand for finished stone is not high, you can use two-stage jaw crusher program for production. This configuration is a low investment, maintenance and maintenance of simple programs, the cost of production is also more economical in all programs. However, the drawback of this program is that the grain size of the stone is relatively poor, the proportion of needle-like material is higher. Stone in the market competitiveness is not high, because the high-grade buildings need fine grain stone.

In order to improve the grain size (polygonal cube), you can use jaw crusher plus impact crusher process configuration. This configuration than the above two-level jaw broken investment costs higher, produced by the stone grain is also very good. However, because the granite is more difficult to break the material, impact crusher wear parts wear is relatively high, long-term production increased production costs are considerable. Because granite has a brittle property, such a configuration is also an acceptable solution.

Requiring the product to be excellent in grain size and at the same time reducing the cost of production, we need to add a laminating crusher between the jaw and the break, such as a fine jaw crusher or a cone crusher. This configuration can make the main crushing work by the first break and two broken to complete (laminated crushing), and finally by breaking the broken broken integer. This configuration process can be large reduction in the formation of anti-material after screening. If a production line in the proportion of anti-material is too high, will make the last crusher to increase the number of repeated broken work, the corresponding wear and tear will make the loss will be greatly increased. Two-level crushing and third-level counter-crushing process configuration, making the investment cost has increased, but it is brought about by the production costs greatly reduced. Its advantage is self-evident.

The specific process configuration needs to be based on the actual situation of the site specific analysis, welcome to visit the exchange.

What are the classification of cone crushers

Cone crusher is a very important gravel production line for the ore crushing processing of mining machinery and equipment, cone crusher to achieve the ideal equipment for more than broken grinding with high production capacity, fine product size, easy machine maintenance, easy to operate And other characteristics.

Cone crusher in the gravel production line is mainly used for fine grinding operations in the ore, cone crusher can be used for limestone, dolomite and calcite and other ore crushing processing, cone crusher because of their own advantages in the gravel production line of concern Of a member.

With the development of economic technology advances more and more cone crusher come out here in Shanghai joyal mining machinery as a professional manufacturer of crusher and we talk about the cone crusher which is a large family members which, hope We can understand the cone crusher this ore crushing machinery and equipment.
