Design of the mineral powder vertical mill production line

Guilin Hongcheng is an enterprise dedicated to the research and development of new environmentally friendly and energy-saving ultra-fine grinding technology and large-scale equipment manufacturing in the steel, electric power, metallurgy, and building materials industries. It has the ability to design and manufacture mineral powder vertical mill production lines. Today I would like to introduce to you the design of the mineral powder vertical mill production line. 

Design of the mineral powder vertical mill production line process

The raw slag enters the feeding bin through the grab machine. After measurement, it is sent to the spiral feeding device by the conveyor belt and fed into the HLM vertical roller mill. The material in the mill moves from the center to the edge under the action of centrifugal force as the grinding disc rotates, and is solidified under pressure. After the degassing and grinding process, the material is brought up by the hot air entering from the air ring to the edge of the grinding disc and immediately dry. The finer particles are taken to the powder separator for sorting, while the coarse powder is returned to the grinding disc for further grinding. The qualified fine powder is brought into the bag dust collector to collect the finished product and separate the air and powder. After the finished products are collected, they are transported to the finished product bulk warehouse, and the exhaust gas is silenced by a fan and then discharged. Some large particles that are difficult to grind (including iron balls and iron slag) enter the external circulation system through the slag discharge port at the air ring. After iron removal, it is sent to the mill again by the elevator for grinding. The hot air required for drying and ventilation of the mill is provided by the hot air furnace, and the insufficient part is supplemented from the atmosphere by the cold air valve. The system has large air volume and strong drying capacity, and the moisture content of the ground materials can reach 8-15%.

Design of the mineral powder vertical mill production line advantages

1. Save land
The entire production line has a compact structure and takes up little space.

2. Low noise and environmentally friendly
When the production line is running, the noise and vibration are very low. In addition, the fan device is equipped with a soundproof room and a silencer to double-process, so that the system noise emission is less than 60-70 decibels, which can fully meet the standards.

3. Significantly save electricity
Due to the advanced grinding mechanism, simple process and small installed capacity, grinding ultra-fine mineral powder can save 45-60% of electric energy compared with the traditional tube mill system, and grinding cement can save 35-40% of electric energy.

4. Dust emission meets standards
The entire production line is operated under negative pressure, and air box pulse bag dust collectors with mature technology and reliable operation are used to collect finished products. Dust emissions during the production process are controlled at 30-50mg/m, which is fully within compliance with the standards.

The HLM vertical roller mill new process production line is used for ultra-fine grinding of medium-hard materials such as granulated blast furnace slag and steel slag, which simplifies the process, requires less floor space, saves investment, significantly reduces power consumption, has long service life and ensures smooth operation. High efficiency, it is an innovative technology of ultra-fine grinding. If you have design requirements for a mineral powder vertical mill production line, please leave us a message.
