1. Raw material requirements:
The moisture content of the material should be adjusted to 14%-18%. If the moisture content is too high or too low, the yield and quality of the particles will be affected. At the same time, the raw materials should be mixed evenly and the water content should be consistent.
2. New die running:
The mold plate should be run-in before the first use. The method is as follows: Take 5 kg of raw materials, 1 kg of fine sand and mix well, then add 1 kg of waste engine oil and mix thoroughly. Start the machine, put the raw materials after mixing, adjust the pressure roller bolts with a wrench, wait until the normal discharge, (Note: the adjustment gap can not be too small, too small will damage the pressure roller and the grinding disc.) Keep the machine running for 1 hour before adding Normal raw materials are produced. If the material cannot be granulated normally after adding the raw material, the roller bolt should be slightly loosened until the normal discharge.
After the adjustment, the granules are still not normal, and the steel nails are used to expose the oil or dry material in the mold plate (the steel nails flatten the head), and then re-run.
When the operator completes the granulation work for one day, after the raw materials in the granulation chamber are pressed, the oil material (mixed with the raw material and 10% waste engine oil) is added to the machine to fill the die hole of the mold to ensure that the die hole is not blocked, so that the operator It will be ready for the next operation and will save a lot of time next time you start the device.
3, the adjustment of the die plate roller gap:
The gap between the pressure roller and the die plate has a great influence on the granulation quality, and the general gap should be between 0.05 and 0.3 mm. When the gap is larger than 0.3 mm, the material layer is too thick and unevenly distributed to reduce the granulation yield. When the gap is less than 0.05 mm, the machine wears severely. Roller and die spacing judging method: Generally, it is not good to turn the press roller into the granulator when the press roller is turned to the time of turning or when the hand is thrown into the granulator (the sound of the press roller pressed to the die plate). Adjustment method: As shown in Figure 1, adjust the screw 8 with an Allen key (spare part), and pay attention to the adjustment of the screws on both sides.
4, the choice of mold hole depth and aperture (compression ratio):
A die with a small hole depth and a small aperture ratio has a high granulation yield but a low hardness, and conversely, a low yield and a high hardness. Therefore, users should choose different mold plates according to their needs, and if necessary, provide raw materials. We can customize the molds for your needs.
5. Adjustment of particle length: Adjust the length of the pellet by adjusting the height of the cutter set on the edge of the discharge port.
6. Replacement method of the mold plate: Use a screwdriver to flatten one of the teeth on the spindle and insert the nut into the notch of the nut. Use a hook wrench (spare part) to unscrew the nut, take out the stopper washer and the flat washer, and then use the die plate screwdriver. (Spare parts) Remove the mold plate. After replacing the new mold plate, re-run the machine as described above.
7. Processed granule treatment: The processed granules have a relatively high temperature and should be placed in a ventilated place to cool to room temperature before being stored in bags.
