Enhanced Roller Grinding Mill

Overview

Clirik enhanced roller grinding mill is suitable for processing various non-flammable and non-explosive mineral materials with Moh's hardness less than 6 and humidity less than 6%, it is widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc,.

The granularity of the finished powder size can be adjusted between 50 and 325 meshes(315-45 micron). Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic,iron ore, carborundum, bauxite, rock phosphate, coal and other materials, total about 400 kinds of materials.

Benefit

Working Principle

Big materials are crushed by jaw crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and are fed evenly and continuously by vibrating feeder into the main unit for grinding. The grinded powder are carried by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter cyclone collector through 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 return pipe on the top of cyclone collector. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure.

Working Features

. Optimized grinding part, increase grinding efficiency

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

. Triple vibrating damping for working stability

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

. New type impeller of classifier with VFD

Equipped the new cage type impeller for classifier, adjust the speed freely by VFD, enlarge the output size range to 80 425 mesh.

. Grinding device adopts superimposed multistage seal, prolong the lubricating cycle.
