The iron ore waste is a kind of industrial solid waste. With the increasing awareness of environmental protection, the recycling of waste has become the main way to turn waste into treasure. What grinding mill can be used in the comprehensive utilization of iron ore waste? HCMilling(Guilin Hongcheng) is a vertical roller mill manufacturer, which meets the demand of solid waste recycling and provides high-output and high-energy special waste grinding mill equipment and selection and configuration scheme, which is conducive to creating value for the project.

Introduction of iron ore slag

The results show that the specific surface area of the slag is 420m2 / kg, the fineness is less than 0.4, and the activity of the slag can reach above S75 level by adding active activator. The pH of cement liquid phase can be reduced to less than 12 after the active base material of cement is mixed with tailing powder. The addition of tailings changed the hydration reaction and products of slag cement, which made it difficult to form a-cs2h, the product of slag cement strength decline. In this paper, the technology of producing cement by using iron ore tailings without burning activation makes a great breakthrough in the comprehensive utilization of tailings, and also increases the application variety of cement raw materials. At the same time, the cost of cement production is greatly reduced, and the technical properties of cement are also significantly improved.

It can be seen that the comprehensive utilization value of iron ore waste is high. With the help of the special vertical roller mill, it can be beneficial to turn iron ore waste into treasure and realize recycling. HLM vertical roller mill machine of HCMilling(Guilin Hongcheng) is a kind of equipment that focuses on grinding iron ore slag, steel slag, water slag and other industrial solid waste, and also a large-scale equipment that can make grinding project produce.

Vertical roller mill for industrial solid waste

The vertical roller mill is a special equipment which meets the requirements of energy saving and emission reduction. Compared with the traditional mill, it integrates crushing, grinding, drying, grading and powder collection. The utility model has the advantages of scientific working principle, more reasonable design structure, small floor area, low noise, small dust, easier maintenance, and less consumption of wear-resistant materials, so it is an ideal mainstream equipment in solid waste grinding industry.

The grinding mill has the following advantages:

1). Excellent environmental protection

The whole system has small vibration, low noise, and the whole system is sealed and operated under full negative pressure, which is conducive to improving the market competitiveness of enterprises.

2). Reliable Performance

It adopts the limiting device of the grinding roller, which can avoid the strong vibration caused by the broken material. Without sealing fan, the oxygen content in the mill can be reduced and the explosion suppression performance is better.

3). High powder rate

Its grinding efficiency is high and energy consumption is low. Compared with ball mill, energy consumption is 40-50% lower.

4). Good drying power

The vertical roller mill can be directly ventilated with hot air, with strong drying capacity, and the moisture content of the feed can reach 15%.

5). Low investment cost

The process flow is simple, the system equipment is less, the structure is more compact, the civil engineering cost is low, and the outdoor layout can be realized.

6). High degree of automation

It adopts PLC full-automatic control system, which can be controlled remotely with low maintenance cost.

The vertical roller mill equipment of HCMilling(Guilin Hongcheng) is the main equipment which is beneficial to realize the recycling value of iron ore waste residue. HCM makes the whole production line realize broad market value with high-yield, efficient, environmental protection and noise reduction grinding mill equipment.
