MTW Trapezium Grinding Mill

The MTW Trapezium Grinding Mill integrates multiple patented technologies, including an overall bevel gear (prick gear) drive system, internal thin oil lubrication, and an arc-shaped air duct. These innovations significantly improve transmission efficiency, reduce energy loss, and enhance long-term operational stability compared with conventional grinding mills.

Thanks to its compact structural design, the MTW mill occupies less floor space, helping reduce civil construction costs and overall project investment. The optimized grinding structure shortens material residence time inside the mill, enabling precise control of product fineness while minimizing over-grinding.

Grinding rollers and rings are manufactured from high-performance, wear-resistant alloy materials, extending their service life by approximately 1.7–2.5 times compared with traditional components. This results in reduced downtime, lower maintenance frequency, and improved production continuity.

The mill operates as a fully enclosed system under negative pressure and is equipped with a professional dust collection system. This ensures low dust emissions, low noise levels, and compliance with modern environmental standards, making it suitable for both urban and remote industrial sites.
