The general solution to this is the most common way is only expected to drop positions, which not only makes the lower production, while the ball consumption, electricity consumption increased. Tide of raw materials, water, raw material in the screw conveyor is running slow, reducing the transmission capacity of the screw conveyor is easy to form the hanging wall material, while in the helical content, spiral leaves wear helix axis heresy, which resulted in spiral transmission operation is low. As the raw water temperature is low, the exhaust moisture, exhaust condensation of moisture in the pipeline, causing pipe blockage, often stop grinding processing mill operation rate.

In the process of cement production, the process of the raw mill grinding of raw material is a complex process. There many factors, such as the structure of the mill process, the grinding media gradation and characteristics of the material itself. The main raw material for the production of raw materials limestone that dumps openly and. Therefore, the production of raw materials is much affected by weather. Winter ambient temperature is low, into the grinding raw material temperature also low, with the temperature in the raw material mill, the large temperature difference. As the big snow water content of raw materials, high temperature grinding, the raw water heat into water vapor and powder adhesion to the grinding media and liner to form a cushioning or blockage of the grate holes of the diaphragm plate, hinder material flow, so that the grinding efficiency and reduce this phenomenon is usually referred to as "full grind".

After Henan Hongxing Mining Machinery"s engineering and technical personnel in-depth study and discussion, the best way to solve this problem has been found. One additional hot stove is installed in the raw material grinding head into the ground. In actual operation, the hot air temperature reached 389 degrees which can solve the phenomena of the material wet the full mill production to Taiwan increased by 3 tons over the same period last year, the mill exhaust gas temperature can reach 90 degrees, emissions into the air temperature above the dew point temperature of 54 degrees, eliminating the pipe condensation. Additional hot stove, the Raymond grinding mill will not only play a role in grinding, play a certain role in drying raw material moisture less than 1% of the screw conveyor operation rate also increased, which makes the raw material grinding system operation over the same period increased by 5%.
