Sand making machine to open the river pebble use the door

River pebbles are natural in a natural ore, the river pebbles for reasonable processing and utilization, is an indispensable step in building a green society. With the depletion of mineral resources, to take reasonable measures to improve the utilization of river pebbles is the focus of the current gravel plant, from the current market trends, the sand making machine will open the river pebble use of the door.

River gravel is an ordinary sand and gravel by the impact of floods, water transport process is constantly under the impact of the formation of the role of extrusion, during the tens of thousands of years after the evolution of the history of the formation of the river pebble high hardness, abrasion resistance, Corrosion resistance is good, the acquisition cost is relatively low, so become a water conservancy, highways, railways, bridges, construction, municipal engineering and other fields in the ideal stone, the application value is extremely high.

It is understood that many areas of China in the treatment of river pebbles there are some problems, such as waste in the process of serious waste; dust and noise and other pollution problems occur frequently; get the river gravel finished grade is low, the application area is limited.

Although the market on the river pebble treatment equipment more, but can really achieve the river pebble resources as undoubtedly sand machine equipment, the market a lot of crusher can only achieve the purpose of the river pebble broken, but broken the size of the size and Shape can not control, can not meet the industrial field on the river pebble grain size requirements, but the sand is different, it is a typical sand making equipment, the river pebbles have a very good shaping effect, the finished product more accurate The

Many processing plants in the river pebble processing, the direct use of crusher for its processing, while ignoring the importance of sand making machine in the production process caused a serious waste of resources, which led to higher and higher costs, To the processing plant to bring a huge financial burden.

Based on a lot of manufacturers do not know how to process the river pebbles, Shanghai joyal machinery company's sand machine experts recommend that for the river like pebble this relatively high hardness of gravel, the user if the finished product shape and particle size requirements are higher, the best Is the use of sand making machine for its processing.

Sanding machine with stone crushing principle, in the course of the operation will not damage the equipment parts, while the river pebble sanding better, but also in the process of running less dust, low noise, to achieve the conservation of resources And the dual effect of protecting the environment, is currently the most favored by the user sand making equipment, will be the use of river pebble resources play a vital role.

With the increase in demand for gravel in the industrial sector, the investment and utilization of river pebbles has become the current hot spot, and the upsurge of exploitation of river pebbles has been set up, which will be a kind of river pebble processing plant and mining machinery and equipment factory. New opportunities and challenges.

Impact Crusher Product Description

Brief Introduction of Impact Crusher

Impact crusher is the use of impact energy can break the material of the equipment. On the use of mechanical energy in the form of the use of the impact of "free" broken crusher, than the pressure of the crushing principle of crushing crusher superior. When the material in the hit plate and counterattack board between the way back and forth, in addition to the impact plate and counterattack plate impact, there are mutual impact between the role of the material.

The working principle of the impact crusher

The counter-crusher uses a plate hammer on a high-speed rotating rotor to create a high-speed impact on the material entering the crushing chamber and break the broken material at a high speed to the other end of the crushing chamber Was broken, and then rebound from the counterattack plate to the hammer, continue to repeat the process. On the way back and forth, there is a collision between the material. As the material by the plate hammer blow, and the impact of the impact plate and the collision between the material, the material continue to produce cracks, loose and crushed. When the particle size is less than the gap between the counterweight and the plate hammer, it is discharged.

Impact crusher classification

Impact crusher according to its structural characteristics can be divided into single rotor impact crusher and double rotor impact crusher.

According to the rotor steering, single rotor counter crusher is divided into two types: reversible rotation and irreversible rotation. Double rotor impact crusher can be divided into the same direction of rotation, reverse rotation and reverse rotation of three types.

According to the internal structure, single rotor counterattack crusher is divided into two parts with uniform rectification board and not even with the rectification board. Double rotor impact crusher can be divided into two types: the rotor is at the same level and the rotor is not in the same level.

Impact crusher performance characteristics

1, crushing ratio (Note: crusher into the material size and the upper limit of the ratio of material size) is very large, the general crusher crushing ratio of not more than 10, and counterattack crusher crushing ratio is generally 30-40, the largest Up to 150.

2, high crushing efficiency, low power consumption. Because the general material of the impact strength is much smaller than the compressive strength, and because the material by the impact of the plate after the high-speed and multiple impact, the material along the powder cleavage interface and fragile tissue first cracked, so this type Crusher crushing efficiency is high, and the power consumption is low.

3, the product size uniformity, less crushing phenomenon. This crusher is the use of kinetic energy to break the material, and each piece of material has a kinetic energy and the quality of the material is proportional to the block. Therefore, in the process of crushing, large pieces of material subject to a greater degree of broken, and smaller cities of the material, under certain conditions are not broken. So broken product size uniformity, too little crushing phenomenon.

4, can be selectively broken. In the process of impact crushing, the material is first broken along the cleavage plane to facilitate the separation of the material from the monomer.

5, adaptability. This crusher can be broken brittle, fibrous and hard in the following materials, especially for brittle materials broken.

6, the device small size, light weight, simple structure, easy manufacturing, easy maintenance.

Based on the impact crusher with these obvious advantages, the current countries are widely used, vigorously develop. But the impact crusher also has shortcomings, broken hard material, the plate hammer (hit plate) and counterattack plate wear faster. In addition, the impact crusher is high-speed rotation and by the impact of the broken machine, parts processing accuracy requirements, and to carry out static balance in order to extend the service life.

The role of flywheel in jaw crusher

Flywheel is a jaw crusher in a very conspicuous big guy, many people wonder how the flywheel in the end is doing? Jaw crusher with two flywheels, one of the flywheel for connecting the V-belt and eccentric shaft, the other from the shape seems to see what role it does not increase the weight of the equipment, can not be removed? joyal machinery in the following will be announced for everyone one by one.

Flywheel is a part of the mine equipment is inseparable from the parts, but also play a key role in the various crusher equipment, the flywheel is playing an irreplaceable role, so the flywheel can not be removed, while the equipment running The process of flywheel also plays a very important role.

From the appearance of jaw crusher equipment, we can easily see that the jaw crusher on both sides of the equipment has two large iron wheels, the two wheels is what we call the flywheel. Two flywheels at both ends of the eccentric shaft, one of the flywheel for connecting the V-belt and eccentric shaft, transmission kinetic energy; the other is a lot of people no use in the eyes of the flywheel, in fact, the flywheel in the jaw crusher running Crucial role. The main reason also from the jaw crusher working principle, jaw crusher is an indirect work of the equipment, which led to the resistance on the eccentric shaft will change, the motor load is uneven, the formation of mechanical rate fluctuations. And this flywheel is to make the motor load evenly, reduce the motor rated power and reduce the mechanical rate fluctuations and installation.

The flywheel stores the energy of the jaw crusher when it is empty and is released when the jaw is squeezed. That is, when the jaw plate moves away from the fixed jaw, the flywheel accumulates energy, and when the flywheel is closed, the flywheel transfers the accumulated energy for the material of the crusher, so that the load of the motor can be made uniform and the rated power of the motor can be reduced. It is because of the flywheel, jaw crusher energy consumption was able to be uniform.

Here, joyal machinery still have to say that not all of the jaw crusher is only a flywheel connected to the V-belt, there are two are connected to the Vane flywheel, if there are two large motor jaw crusher Are a dual purpose, the two flywheels are regarded as a pulley connected to the V-belt. This simplifies the equipment of the organization, but also make the best use.
