What is MTW Grinding Mill?

Traditional ordinary grinding mills generally suffer from many technical drawbacks in long-term industrial production. The split transmission structure causes low transmission efficiency and frequent mechanical failures. Manual grease lubrication leads to poor heat dissipation, high operating temperature and rapid wear of core parts. Straight air duct design generates large wind resistance, resulting in serious energy loss and low unit output. In addition, uneven feeding and single grinding structure easily cause unstable powder fineness and low finished product qualification rate, restricting enterprise production benefits.
Our MTW Grinding Mill completely solves the inherent defects of traditional milling equipment through comprehensive European technological upgrading and structural optimization. Adopting exclusive trapezium grinding structure, high-precision integral bevel gear drive and full automatic thin oil circulation lubrication system, the equipment achieves qualitative improvement in grinding efficiency, operational stability and energy-saving performance. It is suitable for non-flammable and non-explosive mineral materials with Mohs hardness ≤9.3 and humidity ≤8%, widely applied in mining, building materials, chemical industry and metallurgy, becoming mainstream medium-fine powder processing equipment in global industrial fields.

Complete Machine Configuration & Composition of MTW Grinding Mill

1. Integrated Bevel Gear Transmission System

Different from the split transmission mode of traditional grinding mills, MTW Grinding Mill adopts one-piece bevel gear transmission structure. It features high gear meshing precision and minimal power loss, increasing transmission efficiency by more than 5%. The integrated structure avoids loose connecting parts and operational failures, ensures stable power output under long-term high-load working conditions, and effectively reduces mechanical vibration and running noise.

2. Full Automatic Thin Oil Circulating Lubrication System

Replacing traditional manual grease lubrication, the MTW Grinding Mill is equipped with independent circulating thin oil lubrication device. It provides continuous and uniform oil supply for bearings and transmission components, realizing fast heat dissipation and full lubrication. This system effectively controls core part operating temperature, eliminates dry friction damage, and extends the service life of bearings and gears by over 2 times. The unattended circulating operation greatly reduces daily maintenance labor costs.

3. Optimized Arc Curved Air Duct Structure

The upgraded arc curved air duct replaces the traditional straight air duct, greatly reducing internal wind resistance and turbulent flow loss. The circulating air flows more smoothly and evenly inside the grinding chamber, significantly improving powder conveying and screening efficiency. Under the same power configuration, the optimized air path effectively increases unit output and realizes high-efficiency energy-saving grinding production.

4. Patented Combined Curved Shovel Blade System

This MTW Grinding Mill adopts innovative combined curved shovel blade structure. The optimized curved feeding angle adjusts the material throwing trajectory accurately, enabling materials to be evenly sent into the gap between grinding roller and grinding ring. It improves grinding uniformity and efficiency, and reduces direct wear of core grinding parts. Only the blade tip needs replacement during maintenance, greatly lowering spare parts cost and maintenance cycle.

5. High-Precision Variable-Frequency Classification System

Equipped with high-speed variable-frequency powder classifier, the MTW Grinding Mill supports stepless fineness adjustment within 80-325 mesh. It accurately screens qualified fine powder and returns unqualified coarse particles to the grinding chamber for secondary re-grinding. The intelligent classification technology ensures concentrated particle size distribution, uniform fineness and high purity of finished powder, solving the uneven powder problem of traditional milling machines.

6. PLC Intelligent Control & Pulse Dust Removal System

Presets professional grinding parameter curves for multiple mineral materials, supporting one-key start, automatic operation and real-time fault self-diagnosis. Multiple safety protection functions including overload, over-temperature and material blockage protection ensure safe operation. Matched with high-efficiency pulse dust collector, the dust removal rate reaches 99.9%, realizing fully sealed dust-free production and meeting global environmental protection emission standards.

Working Principle & Production Flow of MTW Grinding Mill

Working Principle

The MTW Grinding Mill adopts advanced European trapezium grinding structure + integral bevel gear transmission + automatic thin oil lubrication system. After raw materials are crushed to qualified particle size, the quantitative feeding system uniformly sends materials into the grinding chamber. The curved shovel blades stably throw materials into the gap between grinding roller and grinding ring for continuous extrusion, rolling and fine grinding.
Under the circulating wind force of the arc air duct, the ground powder rises with the air flow and enters the high-precision variable-frequency classifier. Qualified 80-325 mesh fine powder is conveyed to the powder collector for finished product collection; unqualified coarse particles fall back to the grinding chamber for secondary re-grinding. The automatic lubrication system ensures stable operation of core parts, and the pulse dust removal system realizes clean, efficient and loss-free circulating grinding production.
