Milling units use points

The company is located in:

1, clean up part of the use of 

(1) clean the sieve should be smooth, intact, smooth operation, no abnormal noise. 

(2) In operation, pay attention to check the food contained in the sieve under the situation, such as containing too much food, should identify the cause and correct. 

(3) When the mesh is blocked, it can not be beat with iron or hard objects, and the long plate brush can be used to remove the blockage; the surface of the screen surface should be promptly repaired or replaced. 

(4) There should be no collision sound during fan operation. After feeding, check the raw materials of stone, miscellaneous row of stone, miscellaneous conditions, such as gravel contains too much food, should identify the cause and rule out. 

(5) Stoner sieve and the damper should be kept clear, the sieve plugging wire brush cleaning, do not beat, so as not to damage. 

(6) Adjust the eccentric rotation mechanism, to release the rubber mat fastening device, tune and then tighten, so that it is in no pre-stress state. 

2, the use of Valley Part 

(1) Rolling length of the compression spring should be 125 mm, if the spring is too much compression, so that the pressure between the rollers is too large, not only grain broken more, and roll loss faster. In addition, the rubber roller spacing should be between 0.5 to 1 mm, and the rubber roller without movement, shaking, abrasion and other conditions, operation should be flexible. 

(2) Open the hopper flapper to start feeding, slowly turn the flow control handle, the unit to achieve the rated productivity. 

(3) adjust the roll, the shelling rate of 85%, if the lower adjustable roll spacing. 

(4) adjust the air volume, so that rice husk, Hutu full separation. If brown rice contains rice husk, should increase the amount of wind. Husk export tube shall not exceed 5 meters, otherwise rice husk will discharge poorly. 

3, the use of coarse grain separation system 

(1) In order to adapt to different grain length of rice processing, the unit is equipped with two kinds of specifications of the sieve, when selected according to grain length to decide. 

(2) after starting up and shut down a few minutes before, the net rough quality can not be guaranteed, this part of the valley should be returned to the separation sieve and separated again. 

(3) Each screen surface should be kept about 2 degrees inclination. If you find more than 40 grains per kg of brown rice, separation of sieve should be adjusted, speed or inclination to be adjusted. 

(4) The production should pay attention to the smoothness of the operation of the sieve body. If it is found to be sloshing, the transmission part and the rack should be inspected and fastened. 

(5) The production voltage should be maintained between 360 ~ 400 volts. 

4, Milling part of the use 

(1) Check the fasteners before turning on, adjusting machine and transmission, and check the machine there is no foreign body, and then turn the rice mill manpower axis to confirm the operation of flexible before the boot. 

(2) rice mill started, the need to be operating properly before production. When the rice accuracy is high or low, you can adjust the discharge pressure gate pressure or a small amount of adjustment knife to make the rice precision requirements. 

(3) Check whether the broken rice increases at any time in operation, whether there is whole rice in the rice bran, whether the output of rice milling machine is stable or not. 

(4) shut down the first shutting the door, and then reduce the discharge pressure, so does not meet the accuracy requirements of the rice back into the hopper. 

5, the use of bucket elevator single, double Bucket is responsible for the delivery of raw materials, net rice and the return of the mission. Boot machine, such as hoist belt slippage, fighting do not move, indicating the elevator jam or belt too loose, you should clear the jam or tighten the belt.
