Process quality of wheat:
1. Hardness, due to the different hardness of wheat, wheat exhibits different characteristics (brittleness and toughness) during the crushing process. 2. Moisture, different varieties and types of wheat must undergo appropriate moisture adjustment to change the structural and mechanical properties of wheat and make wheat suitable for the requirements of the milling process.
Grinding process parameters:
1. Bachelor, when grinding high-quality flour, the core grinding system adopts the bachelor, which first polishes the surface of the grinding roller, and then processes it with a matte surface. 4 aspects of degree and arrangement.
Operation indicators of the pulverizer:
1. Rolling distance, the distance between the surfaces of the two grinding rolls on the center line of the two grinding rolls is the rolling distance. 2. The feeding of the mill, the grinding effect of the flour mill is largely related to the feeding mechanism and the uniformity of the feeding speed. 3. The unit flow rate of the flour mill, the unit flow rate of the mill refers to the contact length of the grinding roller per centimeter of the mill, and the quality of the grinding material per unit time, expressed as . 4. Air suction and cleaning of the grinding roller, when the material is crushed by the grinding roller, part of the mechanical energy is converted into thermal energy, which makes the grinding roller and the material heat up, and sometimes the surface temperature of the grinding roller is as high as 60-70 °C.
The surface of the grinding roller of the flour mill is not cleaned properly, especially the high moisture content of the grinding material and the high pressure between the grinding rollers will cause the material to stick to the surface of the grinding roller or the groove of the toothed roller, which will affect the grinding effect.
