Micro powder grinding mill/ultrafine powder vertical roller mill

Micro powder grinding mill/ultrafine powder vertical roller mill

It can grind not only Barite, but also other 100 kinds of materials, such as gypsum, calcite, coal, chalk, limestone, dolomite and so on. It ismainly applied to non-inflammable, non-explosive and brittle materials with Mohs hardness scale under six.

The Product fineness of Barite Milling Machine can be controlled between 325~3000 mesh.

Performance and Features of 3000 mesh CLUM vertical grinding mill/vertical roller mill

1. High efficiency

Under the same final size and power, the product capacity of Barite Milling Machine twice than jet mill and agitation mill.

2. Long lifetime of wearing parts

The lifetime of its wearing parts can reach to more than one year, about 2-5 times as long as that of vertical shaft impact crusher and turbo-mill.

3. Security and reliability

There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding or wear of bearings and seal components will never happen

4. High fineness of products

The product fineness can reach D97≤5μm.

5. Environment friendly

The application of dust collector and muffler reduce the pollution and noise, which has reached national environment protection standard.

Production iguration of 3000 mesh CLUM vertical grinding mill/vertical roller mill

The whole set vertical roller grinding mill consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, powder collector, dust collector, air blower, air compressors and electrical control systems.

Working Principle

• The crusher will crush the big materials into small ones, and then the elevator will send them to the hopper.
• The vibrating feeder will send the materials to the middle of first dial evenly.
• The motor of main equipment drives the main shaft and dial through reducer, and the dial drives of rollers moving in the ring channels via pins.
• The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings.
• The high pressure centrifugal blower will inhale air from outside and bring the crushed materials to classifier.
• The rotating turbo in the powder collector will make the coarse materials return to the mill and regrounded, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it.
• The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.

Application of micro powder grinding mill/ultrafine powder vertical roller mill

Micro powder grinding mill/ultrafine powder vertical roller mill are suitable for huge capacity producing, widely used in grinding non-flammable and non-explosive materials under 9.3(the Moh's hardness), such as quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, especially for slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.

Technical Data of micro powder grinding mill/ultrafine powder vertical roller mill

Working Principle of micro powder grinding mill/ultrafine powder vertical roller mill

The grinding disc is driving by motor through reducer. The material falls to grinding disc from the feed opening. The materials are driven to the edge of disc by the centrifugal force and crushed into fine powders by rollers. Then, the hot air from the nozzle take the fine powder to high effiency classsifer.The qualified powder are taken by the air to the powder collector to be collected, while the unqualified powder are sent back for regrinding.
