Blast furnace slag (blast furnace water quenched slag) is the main solid waste of iron and steelmaking in metallurgical industry. China's crude steel production has been the world's largest for many years, while the production of 1 ton of crude steel produces 0.5 ~ 1 ton of slag. The treatment of slag usually accumulates in the open air or buried underground, encroaches on large areas of land, pollutes and poisons soil, water and atmosphere, severely affects ecological environment, and causes huge economic loss and resource waste.

SZM系列磨机减速机概述

The development of milling machine and slag powder technology makes the production of building materials such as brick, cement and thermal insulation wall become the main direction of slag reuse. The blast furnace slag is ground into the most economical 400-450m2/kg superfine slag powder (superfine powder), which is directly supplied to the concrete mixing station as the admixture to form a new type of green building material.
 
 
The blast furnace slag has high hardness, great abrasion and difficult grinding, and the target product is operating under heavy load continuously in the dust environment. Cause: overhanging wheel teeth fatigue fracture and impact fracture, bearing shell impact damage; The precision of spiral bevel gear input is high, and the requirements of modulus and tooth are broad. The installation requirements of the upper coupling are high, ultra-fine dust enters the gear box, aggravates meshing wear and leads to "burning tile", poor reliability and stability, and high operation and maintenance costs. More than 3000KW mill gear boxes as grinding equipment for the core heart has been dependent on imports.
