1. Use of cleaning parts (1) The cleaning screen should be smooth, intact, and stable in operation with no abnormal noise. (2) During the operation, pay attention to the condition of food contained in the sieve. If there is too much grain, check the cause and correct it. (3) When the screen hole is clogged, no iron or hard objects can be used to knock it. The long board brush can be used to clear the blockage; the cracked part of the screen surface should be promptly repaired or replaced. (4) There should be no collision sound during fan operation. After feeding, check the stone, miscellaneous and row of stones in the raw materials, miscellaneous conditions, such as sand contains too much grain, should find out the reason and rule out. (5) Stone removal screens and all dampers should be kept open. Wire plugs should be used to clean the screening holes. Do not knock so as to avoid damage. (6) When adjusting the eccentric rotation mechanism, loosen the rubber pad fastening device, adjust it and then tighten it so that it is in a non-prestressed state. 2. Use of Silicon Valley Part (1) The length of the nip compression spring should be 125 mm. If the spring is compressed too much, the pressure between the nip rolls will be too large, not only the grain breaks, but also the roll loss will be faster. In addition, the distance between the rubber rollers should be between 0.5 and 1 mm, and the rollers should be free from turbulence, shaking, grinding, etc. The operation should be flexible. (2) Open the hopper board and start feeding. Slowly turn the flow adjustment handle to make the unit reach rated productivity. (3) Adjust the roll so that the shelling rate is 85%, and if it is low, the small roll spacing can be adjusted. (4) Adjust the air volume so that the rice hulls and husks are fully separated. If brown rice contains rice hulls, the amount of air should be increased. The rice husk exit pipe must not exceed 5 meters, otherwise the rice husk will not be discharged smoothly. 3. Use of Roughness Separation System (1) To adapt to the processing of rice with different grain lengths, the unit is equipped with two types of sieves, which are determined according to the length of rice grains. (2) After starting and several minutes before shutdown, the net roughness quality cannot be guaranteed. This part of the grain should be returned to the separation screen and separated again. (3) Each screen surface should maintain an angle of about 2 degrees. If more than 40 grains per kilogram of brown rice are found, the separation mesh, rotation speed or inclination should be adjusted. (4) The smooth running of the screen body should be paid attention to at any time during production. If any shaking is found, check the transmission parts and the frame and tighten it. (5) The voltage in production should be maintained between 360 and 400 volts. 4, the use of rice milling parts (1) Check the fasteners, regulators and transmission agencies before starting the machine, and check whether there is no foreign body inside the machine, and then manpower to turn rice milling machine axis, confirm that the operation can be flexible before starting. (2) After the rice-milling machine is started, it needs to be normal before it can be produced. When the out-migration precision is high or low, the pressure of the discharge pressure gate can be adjusted or a small amount of adjustment of the rice knife can be used to make the rice precision meet the requirements. (3) Observe whether the broken rice is increased, whether there is an entire meter in the rice bran, and whether the output of the rice mill is stable. (4) When the machine is shut down, the material gate is closed first, then the discharge pressure is reduced, so that the rice grains that do not meet the accuracy requirements are returned to the hopper. 5. The use of bucket elevators, single and double buckets, is responsible for the task of conveying raw materials, net rice, and back-to-back objects. If the hoist belt slips and the bucket does not move during start-up, it means that the hoist jams or the belt is too loose. It should clear the jam or tighten the belt.
