Shale is a sedimentary rock composed of clay minerals and other materials, and it has various industrial uses, including as a raw material for bricks, cement, and ceramics, as well as in the oil and gas industry.

Shale powder grinding mills are specialized equipment used to grind shale into fine and ultrafine powder. The choice of shale grinding mill depends on the specific requirements of the project, including the desired fineness of the final product, the hardness of the shale, and the production capacity needed. 

1. Raymond Mill

  1. Design: Consists of a host machine, analysis machine, blower, finished cyclone separator, plumbing device, and motor.
  2. Operation: Material is fed into the grinding chamber where it is ground by rollers. The ground material is carried by air from the blower to the separator for classification.
  3. Adjustment: The fineness of the powder can be adjusted by changing the speed of the classifier.
 Raymond mill
  1. High grinding efficiency and low energy consumption.
  2. Small footprint and compact design.
  3. Easy to operate and maintain.
Ideal for processing non-metallic minerals like barite, limestone, kaolin, and ceramics.

2. Ultrafine Grinding Mill

  1. Design: Incorporates advanced grinding technology to produce extremely fine particles. Utilizes a high-speed rotor and stator system for effective grinding.
  2. Operation: Material is fed into the mill and ground by high-speed collisions and friction, resulting in ultrafine particles.
  3. Particle Size: Capable of producing particles in the range of 325-2500 mesh (45-2 microns).
 Ultrafine grinding mill
  1. Produces extremely fine and uniform particle sizes.
  2. High efficiency and low energy consumption.
  3. Suitable for processing a wide range of materials, including those with high hardness.
Ideal for industries requiring fine and ultrafine powders, such as cosmetics, pharmaceuticals, chemicals, and fine ceramics.

3. Ball Mill

  1. Design: Comprises a cylindrical drum rotating around a horizontal axis, filled with steel or ceramic balls.
  2. Operation: Material is fed into the drum and ground by impact and attrition between the balls.
  3. Wet/Dry Grinding: Can operate in both wet and dry conditions.
 Ball mill
  1. High grinding capacity and uniform particle size distribution.
  2. Can handle a wide range of materials, including ores and other hard materials.
  3. Simple structure and robust design.
Used in mining, building materials, and chemical engineering industries for producing powders.

4. Vertical Roller Mill

  1. Design: Combines crushing, drying, grinding, and classifying in one unit.
  2. Operation: Material is ground by rollers directly on the rotating table. Airflow helps to dry the material and transport it to the classifier.
  3. Efficiency: High energy efficiency due to the combined operation.
Ultrafine Vertical Roller Mill 
  1. Low energy consumption and reduced operational costs.
  2. Stable and consistent product quality.
  3. Capable of grinding large volumes of material.
Suitable for large-scale production of powder, including cement raw material, clinker, slag, and coal.

5. Hammer Mill

  1. Design: Consists of a rotor with swinging hammers that impact and break the material against a screen.
  2. Operation: Material is fed into the mill, where it is struck by hammers and reduced in size. The material is then passed through a screen to achieve the desired particle size.
  3. Reduction Ratio: High reduction ratio and high production efficiency.
 Coarse Powder Hammer Mill
  1. Simple structure and easy maintenance.
  2. Can handle relatively large feed sizes.
  3. Versatile for various materials, especially brittle ones.
Suitable for grinding brittle materials, including shale, limestone, and gypsum.

6. High-Pressure Grinding Mill

  1. Design: Equipped with a high-pressure spring that enhances the grinding force.
  2. Operation: Material is crushed between a fixed grinding ring and a roller. The increased pressure improves the grinding efficiency.
  3. Fineness Adjustment: Finely adjustable output particle size.
 High pressure grinding mill for shale
  1. High grinding efficiency and fine powder output.
  2. Suitable for materials with Mohs hardness less than 9.3.
  3. Reduced power consumption compared to traditional mills.
Widely used for processing non-flammable and non-explosive materials like barite, limestone, dolomite, and shale.
