Technical Data

Equipment composition

The standard configuration of the CLRM enhanced roller grinding mill consists of a main unit, reducer, powder classifier, cyclone powder collector, dust cleaner, blower, electrical cabinet, and pipes. The optional accessories include a crusher, bucket elevator, and feeder.


Working Principle

Big-size materials are crushed by jaw crusher to the required particle sizes, carried by bucket elevator to the storage hopper, and fed evenly and continuously by vibrating feeder into the main unit for grinding. 

The grinded powder is held by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter the cyclone collector through a pipe, and are separated and collected there. 

They are discharged at the discharging valve to become finished products; the airflow is sucked to the blower by the return pipe on the top of the cyclone collector. 

The whole airflow system is a sealed circulation and is circulated under positive and negative air pressure.

Advantages of CLRM Enhanced Roller Grinding Mill 


1. Optimized grinding part, increase grinding efficiency

Compared with the previous mill the grind pressure increased by 10%, grinding area up 15 -20%. Optimized the roller layout, and escalated the efficient grinding space.

2. Triple vibrating damping for working stability

Triple damping to resist the vibrating transmit in the main unit base, volute airflow house, unit body, and grinding part. Be sure of the stable grinding condition.

3. New type impeller of the classifier with VFD

Equipped the new cage-type impeller for the classifier, adjusted the speed freely by VFD, and enlarged the output size range to 80 425 mesh.

4. Grinding device adopts a superimposed multistage seal, prolonging the lubricating cycle.

CLRM Enhanced Roller Grinding Mill Application Area


CLRM enhanced roller grinding mill is suitable for processing various non-flammable and non-explosive mineral materials with Moh's hardness of less than 6 and humidity of less than 6%. 

Enhanced roller grinding mill is widely used in metallurgy, construction, the chemical industry, mining, highway construction, etc. 

The granularity of the finished powder size can be adjusted between 50 and 500 mesh (315-45 microns). 

Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal, and other materials, a total of about 400 kinds of materials.
