Three Ring 47μM 7.5t/H 800mm Dia Raymond Roller Mill

Three ring medium speed superfine grinding machine used mill powder for arbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite

Introduction:

The three ring medium speed superfine grinding machine is mainly used for processing non flammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤ 6, such as calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum More than 100 kinds of materials, such as alunite, graphite, fluorite, phosphate rock, potassium ore, pumice and so on, the fine powder particle size can be adjusted between 325-3000 mesh, and the output can reach 0.6-6.5 tons per hour.

Advantage:

1. High efficient and energy saving
Compared with other grinding mill, the capacity will be double based on the same final size and motor power.

2. Long service life for wear parts
Rollers and rings are made of special materials by forged method.Generally, the service life is one year. If the machine is used to grind calcium carbonate or calcite, the service life can be 2-5 years.

3. High safety
No rolling bearing and screw in the grinding chamber.
4. Superfine fineness
The fineness can be D97≤5μm for one time.
5. Environmentally friendly and clean
The fine is collected by pulse dust collector, silencer is used to reduce the noise.

Working principle:

1. The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of roller which are rolling in the ring,which are driven by dial through plunger.
2. Big material is crushed into small particles by hammer crusher,and then small products enter the storage silo by the elevator,and finally the material is sent to bulk material plate by vibrating feeder and feeding pipe uniformly.
3. The material is scattered to the edge and fallen into the ring rolling,then it is impacted,rolled,grinded and turned into the powder by the ring. The air is sucked into the the machine by high pressure fan, the crushed material is put into the classifier.
4. Coarse materials is returned to grind again by the rotating blade, required fine powder entered the cyclone dust collector and dischareged by the discharge valve ,which is the final product. Airflow with some fine dust is discharged by the fan and silencer.
