What Is MTW Grinding Mill?

The MTW Raymond Mill is a high-performance upgraded grinding equipment in the Raymond mill series. It is developed by integrating advanced European grinding technologies and concepts, mainly targeting fine and medium - grade grinding tasks. It has achieved significant improvements in output, energy efficiency, and environmental performance compared to traditional Raymond mills. It is widely used to grind limestone, gypsum, marble, dolomite, kaolin, diatomite, silicate, slag, flyash, percerlite, bartie etc

Why Choose MTW Series Raymond Mill?

1. Increased Grinding Area: The curved grinding ring and wider roller design increase the working surface by 15-20% compared to traditional Raymond mills.

2. Optimized Airflow: Streamlined air duct design reduces turbulence, improving material circulation and classification efficiency.

3. Finer Particle Distribution: Advanced classifier with variable-frequency control achieves 80-600 mesh with narrow size distribution.

4. Contaminated-Free Processing: Closed negative pressure system prevents oil contamination and external dust ingress.

5. Stable Performance: Spring-loaded grinding pressure maintains consistent compression regardless of feed variations.

High Quality

MTW Raymond mill uses a Trapezoidal Working Surface. This ensures that your production capacity doesn't drop significantly as your wear parts get older. It maximizes the grinding efficiency of every rotation.
Customized Design

Integral Bevel Gear Drive. The motor connects directly to the main shaft via an internal gear system. It is compact, quieter, and transmits power with much higher efficiency. No more belt slippage means consistent speed and higher tonnage.
Good Performance

Internal Thin-Oil Lubrication. The main shaft and bevel gears are constantly bathed in clean oil pumped internally.The bearings last longer, and the maintenance interval is extended significantly.

Product features

Curved Air Duct For Better Airflow. The air channel is curved and streamlined.The air flows smoothly with less resistance. This means the fan works less hard to move the same amount of powder, lowering your electricity bill.

Working principle

The entire MTW raymond mill grinding process forms a closed - loop cycle. Firstly, bulk materials are crushed to the required particle size by a jaw crusher, then lifted to the hopper through a bucket elevator, and evenly fed into the grinding chamber by an electromagnetic vibrating feeder. Inside the chamber, the materials are ground between the rotating grinding rollers and the fixed grinding ring. The fan - generated airflow carries the ground powder into the classifier. Particles that meet the fineness requirements are sent to the cyclone collector for collection and discharged as finished products. Those unqualified coarse particles will fall back into the grinding chamber for re - grinding. The separated airflow returns to the fan through the return air pipe for recycling.
