The MTW series euro-type trapezium mill is a high-efficiency mining machine featuring innovative structural designs, such as bevel gear transmission and an internal thin oil lubrication system. It boasts advantages such as high output (up to 60 tons/hour), low energy consumption, advanced classification technology, and precise particle size adjustment. With its arc-shaped air duct design, annular water cooling, and extended oil change intervals (4 months), this mill extends equipment life and reduces maintenance costs. It is an ideal choice for grinding limestone, gypsum, and other non-metallic minerals in industries such as construction and metallurgy.
Working Principle
During the operation of the main unit, the grinding roller assembly not only rotates around its central axis but also revolves around the grinding ring. The grinding roller itself rotates through friction, which not only thoroughly pulverizes the material but also ensures uniform wear around the roller, thus extending its service life. A baffle blade installed below the grinding roller hanger rotates synchronously with the grinding roller. During this process, the baffle blade throws the material up and feeds it into the grinding ring of the grinding roller, forming a cushion layer. This cushion layer is pulverized under the outward centrifugal force generated by the grinding roller (i.e., the compressive force between the grinding roller and the grinding ring).
Product Structure
The system consists of a grinding mill, separator, blower, jaw crusher, vibrating feeder, hopper, dust collector, pipeline, powder collector, electrical cabinet, motor, etc.
Product Advantages
- Integral bevel gear transmission: Compact structure, high transmission efficiency, reduced energy consumption, and easier installation and maintenance.
- Internal thin oil lubrication system: Automatic lubrication, oil change interval approximately 4 months, significantly extending bearing life.
- Variable frequency air classifier: Finished product fineness can be flexibly adjusted within the range of 80–425 mesh (0.177–0.038mm), with a finest reaching over 325 mesh.
- Environmentally friendly design: Equipped with a pulse dust collector and air self-circulation system, achieving dust-free operation in the workshop and meeting national environmental protection standards.
