Flour mill is main equipment in flour plant used for flour milling. It is mainly used for wheat processing, and it can be also used for processing of other coarse cereals. A couple of grinding rolls which rotate towards the same direction at different speeds peel away wheat husk, get wheat endosperm separated from wheat husk, and mill it until it becomes flour. During operation, the materials are under the effects of breaking, shearing, peeling and scraping, which can achieve a certain milling effect. Each set of flour mill is equipment with two sets of independent transmission, feeding & milling systems, and they function separately in the milling line as per different technical parameters of each system - peel, core, residue, tail.
Fully-automatic air pressure control mode is adopted, with not only single-machine control but also remote centralized control allowed; besides, fully-automatic control via computer is also allowed. Feeding is conducted via frequency conversion. When the feeding sensor of flour mill is shutdown, quick blow-down and presetting of speed parameter of feeding roll can be achieved.
Besides pneumatic clutch, electromagnetic clutch can also be adopted for the feeding roll of flour mill, because it is featured with small size, low cost, easy installation and reliable performance.
Grinding roll is of eccentric lever clutch structure and separately placed on gray pig iron rack. Grinding roll group bears the working stress independently.
Grinding roll is placed horizontally, so the materials can enter into grinding zone easily, and assembly & disassembly as well as maintenance are also easy.
Three-round constant-speed tooth-wedge belt transmission mode is adopted for quick-slow roll, with large transmission power, free of jumping gear and displacement. Besides, the roll can operate steadily, with low noise.
The racks at both sides of flour mill are of up-down structure, and an anti-vibration pad is set where the bearing pedestal of quick-slow roll is connected with the lower rack.
Core grinder is equipped with a negative pressure suction device which can improve the feeding condition and lower the temperature of grinding roll and materials.
Pneumatic components and bearings are imported from abroad, and tooth-wedge belt is of high quality, so as to guarantee satisfactory performance of the whole set of equipment.
The whole set of equipment is of totally-closed compound structure, with electrostatic spraying process adopted for its surface. The color is bright and no discoloration occurs for a long time.
