HJRMvertical mill manufactured in our company is a kind of roller mill which can match 2,3 or 4 rollers according to the request. Each roller is composed of fixed rocker arm, frame of rocker arm and hydraulic system which come into grinding power unit , is a complete or standard parts. It is arranged into two compartments, three compartments or four compartments around mill disc.

Introduction

HJ Vertical mill is one kind of roller mill. As requested ,it equip with 3 or 4 rollers. Each roller is composed of foxed roller, support of installation rocker arm and hydraulic system. Motive force unit is in the whole or a standard art. It can be arranged in two components, three components or four components around dill disc.

Work Principle

Raw material feed into discharge pipe through rotary discharger . Discharge pipe enter into the mill through the side or the center if mill disc with the help of gravity and air flow. Mill disc connect with the reducer constantly. Constant speed rotation of mill disc will distribute material with the function of pressure and friction.

Centrifugal force will make pulverized material at the edge of mill disc from the middle of the disc. Material off mill disc will enter into hot gas in the mill through air ring. Via the middle of the mill shell and enter into the Separator. During the process, material will exchange hot gas. The moisture will be evaporated .The rest moisture can reach 1%.Unpulverized material as request will be selected by the Separator and send back mill disc.

Look from the technology and economy, HJRM vertical mill is an advanced grinding equipment. Comparing with traditional grinding equipment, the advantages are as the follows:

Grind all kinds of different material

Small area

Low consumption

Convenient adjustment

Quick control response

Convenient maintenance(Not need to dismantle the easily wear-out parts

Small vibration from start to stop

Small noise

Strong adaptability

Vertical mill has stable quality, competitive price and excellent after sell service

Vertical Mill

Description of Vertical Mill:
Our HJRM type vertical mill can be used to grind materials with a diameter less than 44mm on the rotary disc by rollers with certain pressure. It has advantages of high grinding efficiency, strong dry capacity, easily adjustable grinding size, low noise, low power consumption, simple process flow, low wear rate, low operation costs, etc.

It is mainly comprised by segregator, grinding roller, grinding disc, pressure device, speed reducer, electromotor, shell, and more.

Features of Vertical Mill:
1. High grinding efficiency and low power consumption. This kind of machine consumes 20-30% lower power. And with the growing of moisture content, its energy-saving effect will be more obvious.

2. Strong dry ability. Air is used to send materials, and the temperature of the air can be controlled according to the moisture content of materials. And this mill can be used to dry materials with moisture content as high as 12~15%, which is much higher than the special dryer.

3. Large feeding size. The feeding size can be as large as 5% of the diameter of the grinding diameter, that is, 40 to 100mm. Therefore, secondary grinding is unnecessary for large-scale and medium vertical mill.

4. Stable chemical composition and even particle size products.

5. Simple process flow and small in size. There is a segregator in the vertical mill, which makes powder separator and elevator unnecessary. Grinded dusty air can directly enter into the environmental protection equipment. So its process flow is quite simple and compact. Its structure size is only 70% of that of the ball mill, and its building space is only 50~60% of that of the ball mill.

6. Low noises, few dust, and environment friendly. There is no direct contact between the grinding rollers and grinding disc, so there is no impact sound caused by the colliding between the steel balls or between the steel ball and lining plate. Compared with ball mill, its noises are 20~25 decibels. Besides, our HJRM vertical mills are sealed totally, so the whole system can work under the negative pressure condition. In this way, raising dust is vastly reduced.

7. Low metal wear rate, long service lifespan and high utilization rate of lining plate and grinding rollers. Because there is no direct contact and impact between metal components, its accessories have less wear and long service life. When this vertical mill processes medium hardness cement materials, its grinding rollers and lining plates can work normally as long as 8,000h.

As a professional manufacturer and supplier of vertical mill in China, Jiangsu Haijian Stock Co., Ltd can also provide you with various other machines, such as vertical raw mill, vertical slag mill, cement production line, cement grinding plant, industrial kiln and furnace, grinding equipment, crushing equipment, environmental protection equipment, cooling equipment, drying equipment, compound fertilizer equipment, packing machine, chemical equipment and electrical control system.
