First, Primary Crushing - Jaw Crusher

When crushing stones, we usually choose jaw crushers. When crushing materials, we mainly rely on two jaw plates to squeeze and bend the materials. The movable jaw and the fixed jaw form a crushing cavity that are large at the top and small at the bottom to realize the crushing of materials. Advantages: Simple structure and light machine weight saves a lot of manufacturing costs. Easy maintenance, large crushing ratio, high crushing efficiency, uniform product particle size, large size of the feeding port, and not easy to block. Disadvantages: The lining plate of the jaw crusher is easy to wear, the energy consumption is high, and the vibration is large.

Second, Secondary Crushing - Cone Crusher, Impact Crusher

1. The cone crusher usually performs secondary crushing for the stone with higher hardness. It adopts the principle of lamination, and uses the crushing cone to perform a gyratory motion in the cone cavity in the shell, which causes extrusion, splitting and bending of the material. It is suitable for medium or fine crushing operations.

Advantages: The crushing cavity is deep, which can work continuously and stably, the power consumption per unit is also low, the operation is stable, the vibration is light, the machine weight is light, and it can be crowded to feed the ore. Larger models of cone crushers can directly fed, eliminating the need for a silo and a feeder.

Disadvantages: The installation and maintenance are more complicated, the maintenance is inconvenient, the rotating body is too high, and the energy is 2-3 times higher than that of the jaw crusher, which indirectly increases the construction cost of the workshop, and the price will be slightly more expensive.

2. The impact crusher usually uses the impact energy to achieve the crushing of soft materials. Adjusting the gap between the impact frame and the rotor can achieve the purpose of changing the particle size and shape of the material. Advantages: small footprint, relatively simple structure, large crushing ratio, strong production capacity, and uniform product particle size can also be selectively crushed.

Disadvantages: The blow hammer and the counterattack plate are easy to be worn. If the hard stone is broken, the wear will be even worse, and it needs to be replaced frequently. It is not suitable for plastic and viscous materials to be broken.

Third, Milling Equipment - Raymond Mill

1. Raymond mill is a commonly used grinding equipment, and its cost performance is very high. It is suitable for grinding more than 200 kinds of materials, and it is recognized and welcomed by most users. Advantages: simple and firm structure, convenient operation, strong adaptability to materials, can achieve 325 mesh grinding, good sealing, and effectively prevent dust from flying.

Disadvantages: The consumption of the grinding body and the lining plate is large, easy to wear, the utilization rate of electric energy is low, and most of the electric energy is converted into heat source and sound which disappears.

In the end, there are also some other auxiliary equipments, such as feeders, vibrating screens, conveyors, etc.
