Basic process of processing pesticide granules

Basic process of processing pesticide granules

1) Groove mixer

Mixing: 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 tank of the trough mixer with a loading factor of 0.5. -0.6, add suitable water or alcohol (according to the formula), cover the lid, adjust the counter to the appropriate time, generally mix it once for 15-20 minutes (you can set the mixing time according to the specific situation). The host starts mixing and mixing. After that, the host stops, remove the cover, jog the motor, pour the material into the loading trolley, and thoroughly clean the machine after work every day.

2, rotary granulator

Connect the granulator to the power supply, connect the air duct, connect the cooling water pipe, the inlet pipe is below, the upper is the outlet pipe, start the power switch, press ON on the inverter panel to adjust the frequency of the inverter (generally For 30-50HZ, depending on the situation, the frequency of the sticky material is lower, and 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, the materials in the mixed trolley are evenly added. The feeding cylinder of the granulator, after the granulator can normally discharge the valve of the air duct, 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) when the batch of materials is processed. After that, first adjust the frequency of the inverter to 0, press the STOP button, turn off the power switch, and disassemble the machine material to clean it.

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. Thoroughly clean the appearance of the granulating knife and the granulating sieve cylinder after each work, 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, and the screen will be removed and cleaned before work. If the work is not working at intervals, wait for the next work. It is necessary to clean the screen to work, so as to prevent the powder from drying out in the mesh, which makes it easy to squeeze the screen.

6, the machine is running normally for 3 months, the equipment should be thoroughly maintained, the oil of the reducer should be replaced, and the new mechanical oil No. 46 should be replaced.

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 larger, and the heat-insensitive opening will 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 regulation when speed regulation

3, drying

First pull out the fluidized bed hopper, put the prepared wet granules in, push back to the main machine, start the jacking cylinder to reset and close the main unit, and then start the induced draft fan and the stirring system. (You can start without stirring at the beginning. Motor, wait for the material to dry a little and then open the stirring motor, so as to reduce material crushing, depending on the specific conditions). Clean the ash system, set the inlet air temperature, the material will start to dry, sample and analyze after a period of time, and shut down after drying. After the fluidized bed hopper is pulled out, it is 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.
