Shale is a sedimentary rock with a complex composition, mainly formed by the accumulation of clay and temperature, but containing components such as feldspar and quartz. Shale is mainly used in industry as wall coatings, ceramic particles, etc. Oil shale is also widely used abroad to extract shale oil for fuel and other industrial purposes. At present, the development and utilization of shale in China is still in its early stages, and many uses of shale need to be developed. Given the rapid development of shale technology abroad, it has provided favorable impetus and reference for China's shale industry. We believe that in the future, China's shale technology will make rapid progress.

The production of shale micro powder in industry can be achieved through the use of Colirick's ultra-fine shale milling machine.

The working principle of shale milling machine:

Shale milling machineDuring operation, large pieces of material are crushed into small particles by a hammer crusher and then fed into a storage bin by a hoist. The material is evenly delivered to the middle of the upper turntable by an electromagnetic vibration feeder. The main motor of the main machine drives the main shaft and each layer of turntable to rotate through a reducer, and the turntable drives dozens of ring rollers to roll and rotate in the grinding ring raceway through a circular shaft pin. Under the action of centrifugal force, the material disperses towards the periphery of the circle and falls into the raceway of the grinding ring, where it is pressed, rolled, and ground by the ring rollers to be crushed. The material is then crushed layer by layer and falls into the second and third layers. The external air is sucked into the machine by the suction effect of the high-pressure centrifugal fan, and the material crushed in the third layer is brought into the powder selection machine. The worm wheel rotating inside the powder selector causes coarse materials to fall back and be re ground, while fine powders enter the cyclone powder collector with the airflow and are discharged as finished products through the discharge valve at the bottom. The airflow with a small amount of fine dust is purified by the pulse dust collector and discharged through the fan and muffler.

Processing fineness of shale milling machine:

The processing fineness of shale powder mill is freely adjustable between 300-3000 mesh (for shale micro powder processing below 300 mesh, our company's high-pressure hanging roller mill can be used).

Performance characteristics of the Colirick shale milling machine:

Our company is a professional manufacturer of ultrafine powder mills in China. After more than ten years of development, the company has formed a domestic professional and has its own ultrafine powder mill production base. We have numerous brand agents in China, especially in Henan, Shanghai, Jiangsu and other regions. Our company has many agents and sales companies. The advantages of this type of milling machine in processing shale micro powder are:

1. The Colirick milling machine has high fineness and pass rate for processing shale micro powder.

High fineness can reach up to 3000 mesh, with a one-time pass rate of D97, and some materials can have a pass rate of up to D100.

2. Environmental protection and low consumption are the design goals of shale milling machines

Through the efforts of our technical personnel, our shale milling machine has low overall energy consumption, high efficiency in processing micro powders, and large output. At the same time, we have adopted a sealed design for the entire production line in the design, which does not produce * * dust pollution. The noise is also controlled below the national standard.

3. A strong after-sales team provides you with production assurance.

Our professional after-sales team can provide convenient on-site installation and debugging services to customers worldwide. Currently, we serve over 200 countries and have after-sales personnel on duty year-round to ensure the normal operation of our customers' micro grinding equipment.

4. Well known brands are trustworthy.

Our company has passed the EU high-quality system * *, indicating that our company is a domestic enterprise that allows ultra-fine grinding equipment to enter the EU market, which has helped to build the brand awareness of our products.
