Product Overview

What is a calcium carbonate powder ultrafine vertical roller mill machine?

The calcium carbonate powder ultrafine vertical roller mill machine is a new type of vertical roller mill suitable for grinding non-metallic ultra-fine powder, which is developed by improving the existing vertical roller mill technology on the basis of absorbing the advantages of foreign ultra-fine vertical roller mill and analyzing the needs of domestic customers.Independent research and development of calcium carbonate powder ultrafine vertical roller mill machine used Adopt multi-head powder separator, Clirik classifier perfect solved the particle cutting point height rate of screening questions, compared with the traditional horizontal classifier, fully guaranteed the fineness of finished product can reach 20% ~ 70% (powder size<2um)(Detection machine: Malvern Micro laser particle size analyzer).After years of material research and development, Clirik’s new wear-resistant alloy steel has been successfully applied to roll, ball mill bearing and other wear-resistant parts, which gives wear-resistant parts extremely long service life and prolonging the replacement cycle of wear-resistant parts.

Product Advantage

What are the advantages of calcium carbonate powder ultrafine vertical roller mill machine?

1.Low Operation Cost

Use the special anti-wear alloy materials for grinding roller and plate liner. Long service time for wear parts,low maintenance.The grinding curves of the roller shell and liner plate are uniquely designed, easy to form the stable material bed,low vibration,high product efficient.It is 20% higher than other equivalent vertical mill in capacity,saving 40% powder consumption compared with ball mill.

2.High Additional Value

Adopting the multi-rotor classifier,the final particles size for D97 5-45 micron are attainable.Equipped with the PLC frequency converter control system, the calcium carbonate powder ultrafine vertical roller mill machine can produce 2 micron (20-70%) powder and adjust powder selection patterns according to client’ different requirements. it has greatly increased the final powder added value and application areas due to the advantages of narrow particle size distribution, unit form particles shape and controllable 2 micron content.

3.Safe And Reliable

The pressure being applied to the grinding roller auto-controlled by the PLC/DSC enables the accurate control of grinding pressure and highly efficiency without manual operation .The roller shell and grinding disc liner plate gap is dual protected by electronic and mechanical caging devices to avoid the heavy vibration and impact.Reducer box and lubricating system are equipped multiple inspection and cycle with double pumps.

The sufficient lubrication and cooling of the bearings for the grinding roller is ensured therefore no excess of lubricating oil in the bearing chamber and no leakage could occur.Equipped with multiple intelligent protection devices the calcium carbonate powder ultrafine vertical roller mill machine main unit can realize the continuous operation with stable,safe and high-efficient performance rather than stop running.
 

4.Environmental Friendly

Product Advantage of CLUM series calcium carbonate powder ultrafine vertical roller mill machine roller and grinding disc do not touch each other directly,there does not have the metal impact noise in low vibration .Compared with ball mill the running noise is 20-25 db lower which would not hurt human’s health. Hermetic seal ensures that the system operates under negative pressure.The final powder is conveyed to the final product silo without dust leakage.The environment is clean, meeting the national environmental protection requirements.

Product Application

Which materials can calcium carbonate powder ultrafine vertical roller mill machine?

Calcium carbonate powder ultrafine vertical roller mill machine can grind non-flammable and non-explosive materials under 7 (the Moh’s hardness), such as quartz, dolomite, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, especially for slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.

Working Principle

What is the working principle of calcium carbonate powder ultrafine vertical roller mill machine?

Calcium carbonate powder ultrafine vertical roller mill machine mainly consists of the motor, reduction gear, grinding rollers, grinding plate, pressure-applying device, classifier, mill body.​ oil station, and electrical system.

Calcium carbonate powder ultrafine vertical roller mill machine machine grinding plate is rotated by the main motor via the reduction gear. Meanwhile, high pressure air enters the mill interior via inlet. Materials then fall onto the center of the grinding plate in rotation by the screw conveyor feeder. Due to the centrifugal force, the materials evenly move from the center of the grinding plate towards its fringe. While passing across the track in the grinding plate, large blocks of materials are crushed and grinded directly by the grinding roller. The fine particles form the material bed, owing to squeezing, where the inter-particle crushing takes place until grind to the fine powder.Calcium carbonate powder ultrafine vertical roller mill machine fine powder continue to move towards the fringe of the grinding plate until they are taken away by strong air flow at the air ring. While the materials along with the air flow pass through the separator located above the grinding plate, the coarse particles return to the grinding plate for re-pulverization due to the action of the rotor blade, the fine particles along with the air flow leave the mill interior and are collected and discharged as finished powder product by the powder collector.
