With the rapid development of industrial production, the amount of industrial waste generated by metallurgical and other industries is increasing. The world's steel industry is developing rapidly, and a large amount of industrial slag ( blast furnace slag), steel slag, nickel slag, phosphorus slag and other industrial wastes will be produced each year. Caused serious environmental pollution and a large amount of land occupation.

Taking the protection of the ecological environment as the starting point, Xinxiang Great Wall Machinery aims to develop circular economy, adhering to the ecological civilization concept of “respecting nature, adapting to nature and protecting nature”, and following the construction concept of “reliable production, advanced technology, saving investment and improving efficiency”. Committed to providing metallurgical, cement and other enterprises with the overall solution of industrial waste recycling resources comprehensive utilization.

In recent years, Xinxiang Great Wall Machinery has successfully cooperated with well-known domestic and foreign enterprises such as Shanghai Baosteel, POSCO, P.T indoferro and Henan Meng Electric Group, and build 120 slag/steel slag/nickel slag/phosphorus slag micro-powder production line. The main equipment used by Xinxiang Great Wall Machinery in these EPC production line is the vertical roller mill. Next, we will introduce the role of the vertical mill in the EPC production line.

1. grinding effect

Industrial waste mainly refers to some industrial wastes produced by steel mills, which improves the overall utilization rate of industrial waste and can improve the comprehensive value of building materials, cement, concrete and other fields. On the other hand, for environmental protection policies, the disposal of these industries waste is also imminent.

Xinxiang Great Wall Machinery GRM series vertical mill integrates fine crushing, grinding, drying, powder selection and conveying. It has high grinding efficiency, large drying capacity, easy adjustment of product fineness, low noise, low power consumption and simple process. It has obvious advantages such as low wear and low operating cost, and can meet the production line of industrial waste slag micropowder production line with an annual output of 200,000 to 1.5 million tons.

2. environmental protection

The vertical mill operating system is in a negative pressure state, no dust spills, and the environment is clean and meets environmental protection requirements. The overall layout of the vertical mill is compact, the floor space is about 50% of the ball mill system, and it can be arranged in the open air, and the investment cost is greatly reduced. It is equipped with PLC/DCS automatic control system, which can be remotely controlled and easy to operate.
