How to choose a suitable crusher according to your own materials, the following is a brief introduction to the six commonly used crushers:

1. Hammer Crusher: Its working part is a lot of hammers hinged on the turntable according to certain rules. When the turntable rotates at high speed, the hammers strike the materials loaded into the machine due to centrifugal force and rotational force to break them. At the same time, they are subjected to The impacted stones collide with each other, the lining board of the machine, and the grating bars, which also promotes the crushing of materials. Although the hammer crusher is simple in structure, compact in size, small in weight and low in power consumption per unit of product, it has high productivity, large crushing ratio, small and uniform particle size of the product in a cubic shape, and less excessive crushing. Continuous and reliable work, convenient maintenance and repair, easy inspection and replacement of vulnerable parts.

Hammer crushers are suitable for: Mineral crushing of various brittle materials. Such as: coal, salt, white Asia, gypsum, alum, brick, tile, limestone, etc.

2. Impact crusher: also known as sand making machine, driven by the motor, the rotor rotates at high speed, and the material enters the first crushing chamber for crushing and collides with the blow bar on the rotor for crushing, and then enters the second fine crushing chamber for crushing. Discharged from the discharge port, the impact crusher has low energy consumption, high output and large crushing ratio. The equipment is small in size, easy to operate, easy to install and maintain, has the function of shaping, the product is cubic, and has a high stacking density. During the production process, the stone can form a protective bottom layer, and the fuselage has no wear and tear and is durable.

The impact crusher is suitable for medium and fine crushing (sand making) of various hard and brittle materials such as various rocks, abrasives, refractory materials, cement clinker, quartz stone, iron ore, concrete aggregate, etc. PCL series impact crusher (sand making machine) is most suitable for construction sand and road construction sand.

3. Jaw Crusher: curved extrusion type, its working principle is that the motor drives the belt and the pulley, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing The movable jaw plate approaches the fixed jaw plate, and at the same time the material is crushed or chopped to achieve the purpose of crushing; when the movable jaw plate moves down, the angle between the toggle plate and the movable jaw plate becomes smaller, and the movable jaw plate is under the action of the pull rod and the spring. , away from the fixed jaw plate, at this time the crushed material is discharged from the lower opening of the crushing chamber. With the continuous rotation of the electric motor, the movable jaw of the crusher will do periodic motion to crush and discharge the materials, realizing mass production. The jaw crusher has the characteristics of large crushing ratio, uniform product size, simple structure, reliable operation, easy maintenance, and economical operating costs.

The impact crusher is suitable for medium and fine crushing of various medium-hard ores and rocks in metallurgy, mining, chemical industry, cement, construction, refractory materials and ceramics and other industrial sectors.

4. Impact crusher: impact crusher for short, uses the hammer on the high-speed rotating rotor to produce high-speed impact on the materials sent into the crushing chamber to crush them, and throw the crushed materials to the other side of the crushing chamber at high speed along the tangential direction. The impact plate at one end is broken again, and then rebounds from the impact plate to the blow bar, and continues to repeat the above process. On the way back and forth, the materials also collide with each other. As the materials are hit by the blow bar, impacted by the impact plate and collided with each other, the materials will continuously produce cracks, become loose and even be crushed. When the particle size of the material is smaller than the gap between the impact plate and the blow bar, it will be discharged. Adjusting the gap between the impact frame and the rotor can achieve the purpose of changing the material discharge granularity and material shape. The impact crusher has the advantages of simple structure, small size, light weight and large production capacity. Therefore, the power consumption is less and the efficiency is high. The ore is broken along the joint plane. Up to 40 simplifies the crushing process. Large crushing ratio. Moreover, the particle size of the crushed product is relatively uniform, and it has selective crushing effect. The shape is mostly cubic.

The impact crusher is suitable for crushing medium-hard materials, such as limestone crushing in cement plants. It has the advantages of large production capacity and small particle size.

5. Compound Crusher: Composite Crusher for short, is a new type of high-efficiency fine crushing equipment that integrates hammer crushing and counterattack crushing. Materials fall vertically from the upper part of the machine into the high-speed rotating impeller. A part of the materials distributed around the impeller in the form of an umbrella produces high-speed impact and crushing. After the materials collide with each other, they will form a vortex between the impeller and the casing to collide, rub and crush each other for many times, and then discharge straight from the bottom. , forming a closed circuit for multiple cycles, controlled by the screening equipment to achieve the required particle size of the finished product.
It has the outstanding advantages of large production capacity, high crushing efficiency, large crushing ratio, small abrasion, low energy consumption, good sealing, stable operation, and convenient maintenance.

The compound crusher is suitable for crushing stones in building materials, mining, metallurgy, and chemical industries.

6. Roller Crusher: During operation, the two rollers are driven by two motors and rotate in opposite directions. The ore is fed from the upper part, and the crushing is carried out in the gap formed between the two rollers. Because metal mines mostly use smooth roller surfaces, the crushing effect is mainly by crushing, with some grinding (when it is a tooth surface, it is mainly by crushing). The crushed materials are discharged by gravity. The characteristic of this kind of crusher is that when the material passes through the middle of the two rollers, it is only pressed once, so there is less over-crushing phenomenon. The roller crusher has the advantages of simple structure, compactness, portability, reliable operation, low price, convenient maintenance, etc., and the crushed product has uniform particle size, small over-crushing, and fine product particle size (can be crushed to below 3.0mm).

Roller crusher is suitable for medium and fine crushing of various ores and rocks with medium hardness or less in mineral processing, chemical, cement, building materials and other industrial sectors.
