Slag powder, which is a high-quality concrete admixture and cement admixture, is recognized as one of the preferred hybrid materials in the world with highly durable concrete structures. Mixed with slag powder concrete has the characteristics of low heat of hydration, corrosion resistance, and steel bond strength, impermeability, anti-scaling, high post-strength.
In order to better meet the utilization of blast furnace slag in cement, concrete, construction industry, chemical industry and steel industry, Kefid has made great efforts in the research and development for over 20 years to provide customers a new type, high efficiency, energy saving,high fine slag mill - overpressure trapezium mill
Over-pressure trapezium mill's multi-stage ladder-shaped roll and grinding ring design reduce the speed of material slip, extende material rolling time and improve the finished product fineness and capacity. Roller assembly through the lever and the horizontal spring link, the resulting radial force to avoid the loss of equipment for large pieces of material. The flexible connection of the host and the separator can reduce the vibration and noise and improve the service life of the equipment. At the same power,high-density high-precision impeller device make the capacity of finished products increased by 50% or more. High efficiency and energy saving centrifugal fan greatly improve the efficiency. Convenient impeller adjustment device improve the accuracy of the finished product.
Kefid has a series of crushing,grinding,beneficiation machine such as jaw crusher, hydraulic cone crusher, impact crusher, sand making machine, vertical mill, European tyep grinding mill, overpressure trapezium mill, raymond mill, ball mill, mobile crushing plant.They have signigicant results in the utilization for iron ore, copper ore, lead and zinc ore, molybdenum ore, gold ore, coal and other mineral resources and recognized by domestic and foreign customers.
