Raymond Trapezium Grinding Mill for Grinding Silica Sand , Potassium Feldspar
Brief Introduction of Raymond Mill:
Mind designed the MTW grinding mill. It is a upgrade grinding mill of MTM trapezium grinder. This new generation grinding mill adopts bevel gear overall drive, trapeziums working surface, inner automatic thin-oil lubricating system, arc air channel and several latest patent technology, which is designed to substitute for ball mill, Raymond mill, vertical mill etc.

Working Principles of Potassium Feldspar Micronized Mill:
1. Loading the stuff for grinding evenly and continuously into the grinding chamber of the main frame. Due to the centrifugal force in rotation, the roller swings go outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring. When the roller rolls, the stuff is thus grinded.
2. After being grinded, the stuff is to be routed to the classifier along wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the cyclone collector together with air flow and is expelled from the powder output pipe as product.
3. In the grinding chamber, since the stuff contains moisture to some extent, the heat generated during grinding makes the moisture evaporate; since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases. In order to enable the grinder to work in negative pressure, the increased air flow is guided to the deduster and sequentially to the atmosphere after purification.
Features of Suspension Grinding Mill:
1. The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.
2. Compared with other milling plants, its passing ratio achieves 99%, which is what other mill can not reach.
3. Driving system of main frame adopts airtight gearing and pulley, and drives smoothly and operates reliably.
4. Main parts of the whole plant are made from cast and steel of high quality. The technic is so subtly that the durability of whole plant can be guaranteed.
5. The electric control system is centralized controlled, so the automaticity is high, no people needed in the operating room.
