Product Description

Introduction

Our rolling machine is a kind of new-type cement grinding equipment developed on the basis of advanced technology, and its grinding system has integrated the rolling, scattering, separating, drying and powder separating into one body. Besides, when used together with a ball mill, it can be used in various process flows, like pre-grinding, mixing, semi-finished grinding, finished grinding, and more. Due to the change in its grinding principles, this rolling machine and its grinding system have more advantages, like 50-100% lower power consumption, and 100-300% higher productivity.

 

Features

1. Heat overlaying weld has been employed to make the maintenance of wear-resisting layer more convenient. Meanwhile, the amount of microcracks is largely reduced, and the service life of roller surfaces is no less than 8000h. It is quite easy to maintain the roller surfaces.

2. Aeronautic hydraulic technique is used to make the hydraulic system more reliable and stable.

3. With the cooperation of its hydraulic system and automatic control system, it can do the work of load control of main driving motor, deviation control of space between rollers, automatic deviation adjustment, and fault diagnosis.

4. Its matched powder separator has scattering, grading and drying capacity, which makes low operation costs and high working efficiency possible.

 

Wear resisting liner

There is wear resist liner on the surface of roller, which is hard surfacing to the rollers.

The wearing surfacing can be repaired by hard surfacing. If needed, you can repair the surface without moving rollers.

HRM & PRM roller 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 HRM and PRM 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.
