Application Areas: Non-metallic mineral powder making in mining, building materials, metallurgy, chemical industry, power industry, etc.
MTW Raymond Mill focuses on grinding and processing materials with Mohs hardness below 7 and water content less than 6%. It performs outstandingly in milling in multiple industries.
MTW trapezium grinding mill is a new European version of the mill launched by Henan Anshun Machinery Equipment Co., Ltd. based on the latest European grinding milling technology and concepts and combined with many years of mill production experience. MTW European Trapezium Grinding Mill adopts advanced technologies such as an internal thin oil lubrication system and arc air duct, and its performance is further improved. "Operation is faster and more convenient" better meets customers' production needs for fine powders of different particle sizes.
MTW European Mill adopts bevel gear integral transmission, precise and stable power transmission, energy saving, compact structure, and easy installation. The combination of internal thin oil lubrication and water cooling devices prolongs the life of key components such as main bearings and ensures the long-term operation of equipment. The arc air duct is cleverly designed with a smooth inlet and outlet that is conducive to material dispersion. It is also equipped with an anti-wear guard plate to reduce energy loss.
The unique curved scraper of the MTW European Trapezium Mill enables precise material guidance, a large effective working area, high output and a wear-resistant scraper blade. Only the scraper blade needs to be replaced to reduce costs. The powder selector adopts advanced frequency conversion technology, which is efficient and accurate in powder selection, ensuring the quality of the finished product.
The MTW Trapezium Mill also has good environmental performance. The negative pressure system cooperates with the dust collector, and the air self-circulation design realizes dust-free operation and reduces material loss and environmental pollution. In terms of operation, the electrical system is centrally controlled, with a high degree of automation and remote monitoring. The vertical structure occupies a small area and is easy to install. It can flexibly adapt to different production needs and is a high-quality choice in the field of powder making.
1. The roller is linked to the booster, stable operation and high production capacity.
2. The bevel gear is used for overall transmission, with low energy loss and high efficiency.
3. The internal thin oil lubrication system is more advanced and reliable.
4. The arc-shaped air duct has small air volume loss and good material fluidity.
5. The curved scraper increases the effective working area and improves efficiency. With a split design, you only need to replace the blade, which reduces costs.
6. No resistance to air inlet volute. Small observation door, no vortex
7. The finished product particle size is adjustable and controllable, and the finished product powder collection efficiency
8. Humanized design, easy to operate.
9. Environmentally friendly and pollution-free, low noise.
1. Difference in Transmission Method
MTW trapezoidal mill adopts bevel gear integral transmission. This transmission method is more stable than some other mills (such as some traditional belt drive mills). It reduces the transmission chain and makes the transmission ratio more precise, thereby reducing the energy loss in the transmission process. Moreover, it has a compact structure and is easy and quick to install and adjust, which is a significant difference from other mills in transmission technology.
2. Different Lubrication System
The main engine, fan and powder selector of the MTW grinding mill adopt an internal thin oil lubrication system and are equipped with a water-cooling device. Compared with many grinding mills that only use simple grease lubrication, this lubrication method can effectively increase the service life of the main bearing system. Some grinding mills do not have water-cooling devices. When working for a long time, the bearing system is prone to heat up, which affects the service life. The lubrication and cooling system of the MTW trapezoidal grinding mill can solve this problem well.
3. Uniqueness of Air Duct Design
MTW European Trapezium Grinding Mill is designed with an arc duct. The straight air duct of the traditional grinding mill may produce greater resistance when the material enters and flows out. In contrast, the entrance of the arc duct is smooth, the resistance is small, and the outlet is conducive to material dispersion. The working surface of its air duct is also protected by a high-strength guard plate, which is in contrast to some grinding mills without special air duct design or protection. It can effectively avoid air energy loss and improve the grinding effect.
4. Advantages of Scraper Design
MTW European Trapezium Grinding Mill curved scraper can better guide the material between the grinding roller and the grinding ring. Compared with the grinding mill with an ordinary flat scraper, the effective working area is increased, and the output is higher. Moreover, the blade of its scraper is made of high-wear-resistant alloy material, and only the blade part needs to be replaced. It has more advantages in the replacement cost of wearing parts than those grinding mills where the entire scraper needs to be replaced, and it also improves the utilization rate of materials.
5. Difference in Performance of Powder Selection Machine
MTW trapezoidal mill adopts variable frequency high-efficiency powder selection machine. This powder selection machine has high motor efficiency, energy saving, F-class insulation, and IP54 protection level. The internal isolation structure is adopted, and the powder selection efficiency and accuracy are very high, which can effectively avoid the phenomenon of "running coarse powder". Compared with some traditional mills with low powder selection accuracy, it can better ensure the quality and fineness of the finished powder.
6. Comparison of Environmental Performance
The mill adopts a negative pressure system and is equipped with a professional dust collector, as well as a unique air self-circulation system. Many ordinary mills are not perfect in dust collection and treatment, and there may be dust overflow. The MTW trapezoidal mill can effectively collect dust, realize dust-free operation, reduce pollution to the environment, reduce material loss, and have better environmental performance.
7. Difference in Operation Convenience
MTW trapezoidal mill electrical system adopts centralized control and a high degree of automation, and it can realize remote monitoring and operation. It has a vertical structure, a small footprint, and a strong set. Compared with some mills with complex structures and dispersion and requiring more manual on-site operations, it is easier to operate and install. It can quickly adjust parameters according to different production needs to adapt to a variety of materials and finished product particle size requirements.

When working, the MTW trapezoidal mill first crushes the material to a suitable particle size, sends it to the storage hopper by the elevator, and then enters the main grinding chamber through the vibrating feeder. In the main machine, the bevel gear transmission drives the center shaft to drive the roller hanger and the roller device. The roller rotates and revolves around the center shaft and rotates on its own. The scraper throws the material into the gap between the roller and the grinding ring to crush the material by centrifugal force. After grinding, the powder rises with the airflow, is classified by the powder selector, and is screened by adjusting the blade speed. The qualified powder enters the large cyclone powder collector, separates it from the airflow, and collects it as a finished product. The unqualified coarse powder falls back and is re-grounded. The airflow is closed and circulated, and the induced draft fan participates in the whole process of material transportation and classification under positive and negative pressure.
