CLUM Series Ultrafine Vertical Roller Mill

Product Introduction

CLUM Series Ultrafine Vertical Roller Mill integrates grinding, grading, conveying, secondary powder selection and finished product packaging. The product fineness can reach 400-3000 mesh, breaking through the bottleneck of low ultrafine processing capacity.

Application Fields

We apply the Vertical Roller Mill extensively across various industries including chemicals, metallurgy, and non-metallic ores. It excels particularly in processing white superfine non-metallic ore powders, supplying high-quality fillers and additives for applications in paper making, coating materials, plastics, rubber, PVC, and printing ink. Our CLUM mill is also widely used to produce superfine dry powder of non-metal materials such as calcite, marble, limestone, dolomite, barite, talc, kaolin, wollastonite, gypsum, feldspar, and pyrophyllite.

Main Structures

CLUM Series Ultrafine Vertical Roller Mill mainly consists of the motor, reduction gear, grinding rollers, grinding plate, pressure-applying device, classifier, mill body, oil station, and electrical system.

Working Principle

Feeding Process

We use a spiral feeder to put materials into the central region of the CLUM series ultrafine vertical roller mill's grinding plate.

Grinding Mechanism

The mill's motor drives the reducer, which makes the grinding plate rotate. The rotation creates centrifugal force that pushes the materials to the plate's edge. In the grinding area, the roller's pressure crushes larger particles, while finer particles grind against each other to form a layer.

Airflow and Particle Separation

After grinding, the airflow guides the pulverized materials. It directs them to the edge of the grinding plate and into the powder selector. Inside the powder selector, blades separate the particles. They filter out coarse particles that don't meet the fineness specifications. These particles are sent back to the grinding plate. The particles that achieve the desired fineness are collected. They are gathered in the powder collector as the final product.

Impurity Removal

If there are impurities like iron blocks, their extra weight makes them fall into the mill's lower cavity as they near the edge of the grinding plate. To handle this, a scraper at the base of the grinding plate comes into play. It removes these impurities and directs them towards the discharging port. From there, they are efficiently expelled from the mill, ensuring the process continues smoothly.

Powder Production Process Flow

We feed raw materials from the hopper into the mill using a belt conveyor. The belt scale controls the weight of the materials, and the iron remover removes any tramp iron. Then, we send the materials to the elevator. They pass through an air lock valve and a screw conveyor before entering the mill for pulverization.

After pulverization, the powder classifier separates qualified powder, which we then send to a tank-type pulse dust collector. From there, a screw conveyor and a discharge valve transport the powder to the final product hopper. Finally, it's packed and sold directly.

Additionally, any coarse materials released by the mill unit are re-fed into the machine for further grinding.

The iron remover on the feeding belt conveyor ensures the safety of the ultrafine vertical roller mill's operation.

Secondary Classifying System

In certain specialized fields, there's a significant demand for high-quality powders, particularly in terms of their cut-off size and the percentage of 2μm content. To address this demand, we will add secondary or even tertiary classifier systems.

Central to our system is the ultra-fine classifier, which serves as the core equipment. Furthermore, we incorporate a buffering silo to temporarily store the powder, a bucket elevator to lift it to the next stage, and a blower to control the airflow. An air-proof discharging valve ensures controlled release of the powder, while pipes and ducts direct its flow throughout the system. A bag filter captures any oversized particles, and a screw conveyor moves the powder along. Finally, a pneumatic conveyor efficiently transports the powder to its destination. Together, these components form a comprehensive system designed to produce powders of the desired quality.
