Vertical Roller Mill

Vertical Roller Mill Basic Introduction

Vertical Roller Mill is the important equipment in cement production. Because of the unique advantage of energy saving, Vertical Roller Mill is not only used in grinding raw materials, but also extensively used in grinding clinker materials and blast furnace slag.

Based on introducing advanced foreign technology and our decades’ grinding manufacturing experience, GM machinery designed the LM series vertical grinding mill. It mixes the best functions of crushing, drying, grinding, conveying, is the ideal equipment in the grinding industry. The LM series Vertical Roller Mill has been prove the most practical mill by our customers all the over the world.

Vertical Roller Mill process technology and strength

Reliability service Vertical Roller Mill

The Vertical Roller Mill comes with automatic remote control system. By inspecting oil cylinder, turning the moving arm, it is easy and convenient to replace roller and liner plate, avoiding the loss because of shut down. The Vertical Roller Mill works under integral seal system, with the advantages of low noise, libration, power consumption and no dust. It is the excellent grinding mill for you.

High performance Vertical Roller Mill

The materials directly contact with the hot air inside the mill, it has the benefits of high dryer performance and energy saving. Through temperature control, different humidity materials could be dried effectively. Final materials are discharged promptly avoiding regrinding, it is convenient to control the final product size and inspect chemical analysis, and its quality is more stable. There is an avoiding direct contact device on the roller and liner to prevent devastating attack and strenuous vibration.

Lower your production cost

It mixes the best functions of crushing, drying, grinding and conveying. With compact layout, it only covers half area of ball mill. It suits for outdoors arrangement. The materials are grinded directly by the roller on the grinder. The energy consumption decreases by 30%-40% compared to ball mill. The roller and liner plate is made of excellent materials; it successfully minimizes abrasion and optimizes working life.

Technology process of LM series Vertical Roller Mill system

Mono-pulse dust catcher, open system of Vertical Roller Mill

Raw materials are conveyed into the raw material storage by bucket elevator, after weighing, de-ironing, are conveyed by belt conveyor to air-lock feeder, insuring the raw material conveyed into the mill without air included. The final products are collected by a mono-pulse catcher, and then conveyed into the final product bin by the screw feeder. The damp particles are dried by the dryer. All the processes are finished with minimum plants to save energy and production cost.

Cyclone and pulse precipitator, closed-circuit system of Vertical Roller Mill

This system adopts a set of screw cyclone precipitator to collect final particles. Part of the gases from the draft fan enters into the mill for recycled use, which minimize the work load of the system. Pulse precipitator can be used as final precipitator.

Mono-pulse precipitator, closed-circuit system of Vertical Roller Mill

The final products are conveyed into the final particles storage by pneumatic conveyor, meanwhile, most of the gases from the draft fan enter into the mill for recycled use.
