Call
Condition: new, power: 90 kW (122.37 HP), Year of construction: 2026, A double rotor hammer crusher is a type of crusher in which two rotors are mounted on a single shaft, combined to form a spinning rotor. The double rotor arrangement enhances the crushing capabilities and provides a more efficient and reliable crusher design compared to single rotor crushers.
Here are some key features and aspects of a double rotor hammer crusher:

ceramic ball mill Working principle
when ball mill working,steel balls inside drum will rotate with the drum to some height,and then steel balls fall down with materials to reach the point of grinding.
Working Principle of Ceramic ball mill
ceramic ball mill ,Intermittent ball mill grinding operation is finished in the cylinder body. When the cylinder rotates, materials ascend to a certain height and then fall along a certain path due to the balls' gravity. Two forces are generated on the balls inside. One is the force on balls through tangent direction; the other is a opposite force in the contrast to the diameter of balls, as a result of the force generated when the balls slide down. These two forces will constitute a couple for the steel balls. The balls are squeezed between the cylinder and the adjacent steel balls, so the couple can make unequal-sized friction force. The balls will orbit along with the cylinder axis and then fall down, which can produce a strong impact force on the ores in the cylinder body and, as a result, the ores will be crushed. In conclusion, the ores in the cylinder body are mainly crushed by composite effect of peeling force, impact force and extrusion force.
Ceramic ball mill also named Intermittent ball mill which adopts the wet intermittent operation, is used for fine grinding and mixing the material such as feldspar, quartz, clay ceramic raw materials. The discharging and the mud size can through through 1000 sieve pore.

Year of construction: 2026, condition: new, functionality: fully functional, A cement clinker grinding mill is a specialized equipment used to grind the hard nodular clinker into fine powder, which is cement. Most cement is currently ground in ball mills and also vertical roller mills, which are more effective than ball mills.
Here are key features and information about cement clinker grinding mills:
1. Raw Materials:
- The main raw material for making cement is clinker, which is produced by sintering limestone and clay. Other materials such as gypsum, fly ash, or slag may also be added during the grinding process to achieve specific properties.
2. Grinding Process:
- The clinker and other additives are finely ground in the grinding mill to produce cement. The grinding process is a crucial step in cement production and contributes significantly to the final quality of the product.
3. Types of Mills:
- Ball Mills: Traditional ball mills are commonly used for grinding clinker. They operate by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.
- Vertical Roller Mills (VRM): VRM technology has become increasingly popular for clinker grinding. These mills use a rotating table with rollers to crush and grind the clinker, providing energy efficiency and a smaller footprint compared to ball mills.
4. Gypsum Addition:
- Gypsum is often added during the grinding process to control the setting time of the cement. It prevents flash setting of the clinker and facilitates the formation of a workable and pumpable cement paste.
5. Quality Control:
- Quality control measures, such as monitoring the fineness of the cement, chemical composition, and other properties, are implemented during the grinding process to ensure the final product meets the required specifications and standards.
6. Clinker Cooling:
- Before grinding, the clinker is produced by heating the raw materials in a kiln. The clinker is then cooled before entering the grinding mill to prevent excessive heat build-up during grinding.
7. Dust Collection and Environmental Considerations:
- Dust collectors and air pollution control systems are often employed to capture and control the dust generated during the grinding process, addressing environmental and safety concerns.
8. Packaging and Storage:
- After grinding, the cement is typically stored in silos before being packaged in bags or dispatched in bulk for distribution to construction sites or for sale in the market.
Cement clinker grinding mills play a crucial role in the cement production process, and advancements in technology continue to improve the efficiency and environmental sustainability of the grinding process.
