After more than one year of research and development, the Institute of Cement Machinery Design of Tangshan, Hebei Province developed and developed a high-performance cement grinding equipment that can meet the technical progress requirements of cement production process equipment.
Super strong wet-resistant high-fine cement mill, according to the grinding and grinding mechanism of high-fine cement mill, a random strong force cleaning mechanism has been installed, and a super-activated lining plate and a diversion-type bulkhead sampan plate have been used inside. In the crushing silo, the layered step lining can increase the height of the crushing body in layers, strengthen the kinetic energy and potential energy of the grinding body, increase the crushing force, and eliminate the internal dead zone and immobile zone. In the screening device, the specially shaped deflector plate increases the ventilation inside the mill and reduces the flow resistance. The 2.5 mm screening device is equipped with a random strong cleaning mechanism, both in operation and in grinding. Before and before grinding, the screening device can be strongly cleaned by the timing controller, so that the screening device can always be kept unobstructed. Through practice, this design not only improves the adaptability to moisture in the mill, but also facilitates the ventilation in the mill and reduces the residence time of the dust in the mill, thereby improving the overall performance of the mill. In the grinding chamber, the reverse spiral lining is configured to change the material and grinding body from the same direction to the reverse direction, which increases the relative friction and contact force between the grinding body and the material, and eliminates the appropriate material humidity. With electrostatic adsorption, the grinding capacity is greatly improved, working conditions are more relaxed, the equipment is easier to operate, the finished product temperature is greatly reduced, and the material flow is smooth without blocking. The comprehensive water content of the material can be increased to 3% to 5%, the energy consumption can be reduced by 5% to 10%, the output can be increased by 10% to 20%, the specific surface area of ​​the cement can reach 350 to 400 m 2 /kg, and the specific surface area of ​​the single grinding slag powder can be Up to 450 to 600 square meters/kilogram, equipment operation rate can be increased to 95% or more.
The cement grinding equipment supported by this technology has created a new reliable way for cement production enterprises to advance technologically and transform their equipment.
