Brief introduction:
After many years of practice and improvement, its structure is getting perfect day by day.
For low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional mill, it is widely used in the field of metallurgy, building materials, chemical industry and mining to process powder. The series is used in grinding the non-flammable and non-explosive stuff which has the Moh’ s hardness below 7, humidity less than 6% , such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite, bauxite, iron ore etc., the final products change from 613 micron to 44 micron. Through the function of separator and blower, it can meet different customers’ demand.

Application:
The purpose of the machine is to grind materials ( more than 300 kinds) in the fields of building materials, mining, metallurgy and chemical industry.
( 1) The materials must be non-flammable and non-explosive materials such as:
a) Minerals: limestone, calcite, barite, dolomite, potassium feldspar, marble, talcum, gypsum, kaolin, medical stone, rock phosphate, etc.
b) Metallurgy materials: manganese ore, iron ore, etc.
c) Chemical materials: active carbon, carbon black, etc.
d) Building materials: glass, ceram, fireproof materials, heat preservation materials, etc.
( 2) Conditions for the application and output granularity:
a) The materials should have the hardness less than 7 in Moh’ s scale and humidity less than 6 percent.
b) The granularity of the end products can be adjusted from 30 to 325 meshes.

Structure:
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% , this is what other mill can not reach.
3. Driving system of main frame adopts airtight gearing¨ and pulley Ñ , drives smoothly and operates reliably.
4. Main parts of the whole plant are made from cast and steel of high quality. The technics is so subtly that ensures the durability of whole plant.
5. The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.
Working Principle:
The operations are as following:
( 1) The materials enter the grinding room of the main equipment, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft.
( 2) The blade carries materials to the space between the grinding roll and grinding ring, and materials are ground as the grinding roller rolls.
( 3) After being ground, the powder is selected by classifier via the cycle wind of the blower and the rough powder will be back to the grinding room for regrinding.
( 4) The qualified powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally. The remained airflow comes out after purification by dust catcher.
