In the field of solid waste recycling, HCMilling(Guilin Hongcheng) provides strong and powerful equipment support for the transformation of solid waste into treasure by virtue of its superior grinding technology and rich experience in manufacturing machinery and equipment. Blast furnace slag is one of the solid wastes with high recycling value. HCM recommends the vertical roller mill equipment to realize the comprehensive utilization of blast furnace slag and help the economic development.


What is blast furnace slag?

Slag is a byproduct of blast furnace ironmaking. Water slag has important use in cement industry, which can be used as cement mixture. It can also be used as concrete modifier to improve the performance of concrete. Using blast furnace slag superfine powder as cement additive can not only solve the problem of blast furnace slag outlet, but also provide a cheap raw material for cement production. At present, water slag has become a favorite raw material in the construction field, hoping to continue to tap its potential value, further expand the application field and create greater value.


The introduction of blast furnace slag grinding mill

The blast furnace water slag mill produced by HCMilling(Guilin Hongcheng) factory is a special equipment developed for the territory. It is famous for its high output, environmental protection, efficiency, cost reduction, noise reduction and other advantages. The vertical roller mill of HCM is an ideal equipment focusing on the solid waste market, and it is also a special equipment for the blast furnace slag industry.


The grinding mill integrates crushing, grinding, grading and powder collection, which is also the four steps of powder production. The material is crushed by the crusher to meet the feeding granularity. Under the centrifugal force, the material moves to the periphery of the grinding plate and enters the grinding roller table. Under the action of grinding roller pressure, the material is crushed by extrusion, grinding and shearing. After grinding, the material is blown by the high-speed air flow at the air ring. On the one hand, the coarse-grained material is blown back to the grinding plate for grinding again. On the other hand, the suspended materials are dried, and the fine powder is carried into the grading machine by the hot air for grading. Qualified fine powder flows out of the mill with air, and is collected by dust collection equipment.


Six advantages of blast furnace slag grinding mill

Low investment costs

Simple process flow , few system equipment, compact structure layout, small floor area, it is 50% of the ball mill, the earth is built locally, and the investment cost is reduced.

Easy maintenance

It is very convenient to replace the liner of roller sleeve and maintain the mill. The roller sleeve of the grinding roller can be turned over for use, thus prolonging the service life of the wear-resistant material.


Stable performance

The grinding roller limit device can avoid the vibration of the grinding mill machine caused by the broken material, and the sealing performance is more reliable.



PLC automatic control system, more convenient operation, maintenance is also convenient.


High grinding efficiency

Compared with ball mill, its energy consumption is 40-50% lower, and its grinding efficiency is high, and its single unit output is high.


Energy saving and environmental protection

Full negative pressure operation, low noise, no dust spillover, it is a new energy saving technology.


Strong drying capacity

It can direct hot air, strong drying capacity, do not need to buy another dryer. It can meet the requirements of materials with water content up to 15%.


Good quality of finished products

The product has uniform particle shape, narrow particle size distribution, good fluidity and strong adaptability. The product contains less iron.


HCMilling(Guilin Hongcheng) factory provides professional vertical roller mill equipment to grind blast furnace slag, which makes the slag become useful slag and be used in various industrial fields. HCM blast furnace slag mill is a new type of environmental protection excellent equipment. More details please contact:
