2. The granulator connects the granulator to the power supply, connects the air duct, and the cooling water pipe is connected. The bottom is the inlet pipe, the upper is the outlet pipe, and the power switch is started. Press ON on the inverter panel to adjust the frequency conversion. The frequency of the device (generally 30-50HZ, depending on the situation, the frequency of the sticky material is lower, the frequency of the material that is easier to be made can be higher). Look at the correct steering of the granulating knife. After everything is normal, it will be mixed in the car. The material is evenly added to the feeding drum of the granulator. After the granulator can discharge normally, the valve of the air duct is opened, the opening size is adjusted according to the actual situation, and the water pipe is opened (the flow rate of water is determined according to the actual situation, and circulating water can also be used) After processing a batch of materials, first adjust the frequency of the inverter to 0. Press the STOP button to turn off the power switch. The machine part must be taken apart and cleaned.
Note on granulator:
1. Adjust the proper distance between the granulating knife and the screen, generally 2-3mm
2. Check whether the sieve ring is fixed before work. Is the screw on the granulating knife fastened, loose or not, and is the mesh in the screen clean?
3. Let the machine run normally for a few minutes, is the operation normal? Start slowly feeding, Note: There should be no hard materials in the added materials, especially iron materials. Adjust the appropriate speed according to the viscosity of the material. If the viscosity is high, turn the speed down to ensure the screen is working. Do not shake in the middle.
4. After each work, thoroughly clean the appearance of the granulating knife and the granulating sieve cylinder, and dry it with a dry cloth. 5. If the mesh does not discharge during work, the mesh of the screen may have been blocked. After the screen is removed and cleaned, work again. If the work is not working at intervals, wait for the screen to be cleaned before the next work, so as to prevent the powder from being blocked in the mesh, which is easy. Crush the screen.
6. The machine should be completely operated for 3 months to completely maintain the equipment, replace the oil of the reducer, and replace it with new mechanical oil No. 46. 7. Turn on air cooling and water cooling according to the material characteristics. If it is sensitive to heat, the air volume will be slightly Open a big point, open a small point that is not sensitive to heat or not open.
8. The material cannot be dropped into the inverter panel during work or cleaning, which makes it easy to damage the inverter panel. Slow speed control when speed regulation 3. Drying first pull out the fluidized bed hopper, put the prepared wet particles into the main unit, push the jack-up cylinder to reset and close the main unit, and then start the induced draft fan and stir. System, (in the beginning, you can start without stirring the motor, wait for the material to dry a little and then open the stirring motor, so as to reduce material crushing, as the case may be). Clean the system, set the inlet air temperature, and the material will start to dry. After the time, the sample is analyzed, and after the drying is passed, the product is shut down, and the fluidized bed hopper is pulled out and sieved.
4, sifting (FS square vibrating screen)
The prepared granules are dried in a dryer, dried and sieved, and passed through a FS square sieve to uniformly feed the feed to the feed port of the sieve, wherein the upper discharge port is a larger granule and the lower discharge port It comes out with smaller granules or powders, which are directly mixed and granulated; the medium-outlet is a qualified product.
5, smash the whole grain: (swing particle machine)
The large particles were uniformly added to the YBK160 rocking granulator (the appropriate sieve was selected according to the particle diameter), and the granules were sifted through a square sieve.
Processing procedure for pesticide water dispersible granules
1) Mixing of trough mixer: Connect the power switch, jog the main motor, if there is no abnormal noise, and if the equipment is running normally, after the main motor is stopped, add the dry mixed powder to the mixing of the trough mixer. Bucket, loading factor 0.5-0.6, add appropriate water or alcohol (according to the formula), cover the lid, adjust the counter to the appropriate time, generally mix once for 15-20 minutes (can be mixed according to the specific circumstances) The main engine starts to mix. After mixing, the main machine stops, remove the cover, jog the motor, pour the material into the loading trolley, and thoroughly clean the machine after work every day.
