Brief Introduction
The CLUM series ultrafine vertical roller mill is widely used in industries like chemicals, metallurgy, and non-metallic minerals. It’s especially good at making fine powders from white non-metallic ores, which are crucial for papermaking, coatings, plastics, rubber, and PVC.
Application Fields
The Clirik ultrafine vertical poller mill is adept at processing superfine dry powders of materials like calcite, limestone, marble, dolomite, barite, talc, kaolin, wollastonite, gypsum, feldspar, and pyrophyllite etc.
Main structures
The CLUM series ultrafine vertical roller mill is primarily composed of a motor, reduction gear, grinding rollers, grinding plate, pressure-applying device, classifier, mill body, oil station, and electrical system.
· Grinding rollers
The grinding plate’s passive rotation via friction is key for crushing and grinding materials.
· Pressure-applying device
It controls the gap between the grinding roller and plate to maintain roller pressure.
· Grinding plate
This section facilitates the grinding process and is driven by the reduction gear.
· Classifier
The multi-rotor classifier efficiently separates fine powders with centrifugal force.
Working principle
The Clirik CLUM Series Ultrafine Vertical Roller Mill operates through a streamlined process:
The main motor powers the grinding plate via a reduction gear.
High-pressure air enters through the air inlet, complementing the grinding action.
Materials are centrally fed into the grinding plate and spread outward by centrifugal force.
he grinding roller crushes and grinds the material into fine particles.
These particles are carried to the periphery by airflow and separated in the air ring.
Coarse particles are redirected for further grinding, while fine particles are extracted and collected as the final product.
Working Features
1. Separation of coarse granules and impurities
These are directed to the lower grinding chamber and discharged via a scraping plate.
2. High-precision multi-rotor classifier
Utilizing frequency control and adjustable rotor speed, it produces a wide range of particle sizes.
3. Adjustable hydraulic system pressure
This feature allows for precise adjustment of roller pressure, accommodating materials of varying hardness.
4. Electronic gap control device
Ensures a safe distance between the roller and grinding plate, effectively preventing excessive vibration due to uneven feeding.

Powder Production Process Flow
1. Feeding and Weighing
Raw materials are fed by a conveyor belt and precisely weighed, with iron contaminants removed by an iron remover.
2. Transport and Pulverization
The materials are then transported to the mill via an elevator and air lock, where they undergo pulverization.
3. Separation and Collection
The classifier separates the fine powder, directing it to a dust collector for collection.
4. Packaging and Sale
The collected powder is conveyed to the product hopper, ready for packaging and direct sale.
5. Recycling for Quality
Coarse materials are recycled back into the mill for re-grinding to ensure product fineness.
6. Safety Assurance
The conveyor’s iron remover is crucial for the safe and efficient operation of the ultrafine vertical roller mill.
Secondary Classifying System
In some specific fields, high quality powders are demanded especially for powders cut-oft size, and 2um content percentage, thus secondary or third classifier system will be added to meet the demand.
With the ultra fine classifier as core equipment, the system includes buffering silo, bucket elevator, blower, air-proof discharging valve, classifier, pipes and ducts, bag filter, screw conveyor, pneumatic conveyor etc.
