Oven slag is water-quenched in a molten state at high temperature and transported to the production or use unit for drying. Due to combustion and slagging in the furnace, the particle size generally ranges from 1mm to 50mm, which is similar to the size of grit. The grinding time is about 45min, and the fineness is controlled between 7% and 10%. The fine coal-fired slag is used as a concrete admixture. The setting time is short, the amount of bleeding is small, and the viscous resistance of the pump is large. Improve the performance of concrete.
Kefid's MTW European type grinding mill is a product developed on the basis of absorption grinding technology and concept, and has a number of independent innovation technologies. This model uses a number of new technologies such as bevel gear transmission, internal thin oil lubrication system, and curved air duct. It has high grinding efficiency and increased output by more than 20%. It is widely used in the field of concrete admixture preparation.
