Technical Parameters

Overview of Raymond Mill (Grinding Mill):

Raymond Mill (Grinding Mill) is mainly used to grind and process variety kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry, etc. Raymond Mill (Grinding Mill) is ideal grinding machine to grind and process the materials such as limestone, gypsum, barite, carbonate calcium, marble, feldspar, dolomite, granite, kaolin, bentonite, bauxite, etc.

After being grinded by the Raymond Mill, the powder fineness can be 30-325 mesh (or 0.613mm-0.044mm), some very fine powder can be up to 1000mesh (or 0.013mm). The powder size can be controlled continuously by adjusting the powder classifier of the raymond mill.

Features of Raymond Mill (Grinding Mill):

◆ The whole plant is 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.

◆ Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach.

◆ Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.

◆ Main parts of the whole plant are made from cast and steel of high quality. The technics is so subtly that insures the durability of whole plant.

◆ The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.

Working Principle of Raymond Mill (Grinding Mill):

◆ Raw material is crushed by jaw crusher to the size required which is suitable for the Raymond Mill (Grinding Mill) ,

◆ Then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for grinding mill. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind.

◆ After this, the ground stuff are carried by the air from the blower into the powder separator (Analyzer Machine) for screening. The fine powers are blow into the cyclone powder collector and are poured out through the output-powder valve as the final products, and the corase stuff after the screening will be recycled back into the grinding chamber for regrinding. The set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.
