2.6 When operating the feeding device of the pulverizer and the granulator, the main motor should be operated under the rated current without clogging.
2.7, various trace elements, vitamins, etc., from the additive inlet of the mixer, quantitatively input, the mixer mixes a batch of materials, feed once, the input time is the beginning of each batch of materials, the control room gives Investing in the signal and investing in time.
3, maintenance and repair 3.1, according to the requirements of the equipment manual for maintenance and maintenance. If there is no special requirement, the bearing injection oil adopts ZG-3 calcium-based lubricating oil, the reducer lubricating oil adopts HJ-60 mechanical oil, and in winter, if the room temperature is lower than -10 °C, HJ-20 mechanical oil is used.
3.2. The equipment should be minorly repaired within half a year and overhauled within one year. Replace the lubricant, clean the bearings, and replace the damaged parts during minor repairs.
3.3. Adjust the tightness of the belt in time. The belt must not have severe slippage when the machine is running.
3.4. The wearing parts of the hammer and screen of the pulverizer, the stamper of the granulating system and the pressure roller shall be repaired, adjusted and replaced in time. Replacement, repair, and adjustment time, depending on the productivity of the feed processing product or the quality of the product, generally when the productivity is significantly reduced, the pellet forming rate and the surface quality are not required, it should be adjusted or replaced in time.
3.5. After the hammer of the pulverizer is worn, it should be reversed or turned over. When the head is turned, the original hammer arrangement should be maintained. When all four corners are worn and need to be replaced with new hammers, each set of new hammers should be weighed. The weight difference of each set of hammers should not exceed 5g. It must be assembled according to the hammer arrangement diagram during installation to avoid strong crusher. shock.

3.6. After using the electronic scale for half a year, it is necessary to check and calibrate its accuracy.
3.7. After each shift, the residue in the die hole should be washed out with the bean cake powder in the particle machine cavity.
3.8, the computer control room is always kept clean and quiet 4, general faults and troubleshooting methods 4.1, the crusher strong vibration, noise is very likely may be:
4.1.1. If the hammers are not aligned correctly, the hammers should be re-installed according to the hammer arrangement diagram;
4.1.2. Individual hammers are not clamped in the pin shaft and should be disposed of in time;
4.1.3. If the fixing bolt of the crusher bearing seat is loose or the bearing is damaged, it should be repaired or replaced in time.
4.1.4. After the pulverizer hammer or the self-contained fan impeller wears, the balance of the rotor is destroyed. At this time, the relevant parts should be replaced in time.
(If the inspection is not the above reason, it may be the two sets of hammers on the corresponding pin shaft of the pulverizer. If the weight difference is too large, the corresponding two sets of hammers should be re-matched so that the weight difference does not exceed 5g.)
4.2. The ash return of the feeding port of the pulverizer is generally due to the excessive feeding amount, which causes the lifting capacity of the pulverizer fan to be insufficient, and the sieve piece and the suction pipe are blocked. At this time, the material in the upper and lower chambers of the sifter should be shut down in time to clear the suction pipe and re-adjust the feed amount of the pulverizer.
4.3. The abnormal sound in the pulverizer is generally caused by a large piece of hard material entering the pulverizer, or the falling parts of the machine are flowing in the smashing room. Immediately after discovering this condition, stop the machine and inspect the crushing chamber and remove foreign matter.
4.4. The coarseness of the finished batch material is generally due to the occurrence of sifting or leakage of the sieve or the improper installation of the sieve after the screen is worn or damaged by foreign matter, and the sifting between the sieve edge and the sieve edge is not strict. It should be handled accordingly.
4.5. The poor fluidity of the mixer and the insufficient uniformity of mixing may be due to damage to the broken arch in the mixer or looseness of the transmission belt. Check the position of the broken arch or the tightness of the drive belt in time.
4.6. Excessive dust in the operation area is mainly due to the fact that the dust-free cloth bag mouth is not tight, the ports of the feed pipe and the upper cover of the mixer are not tightly sealed, resulting in leakage of ash, and the fan casing, the conveying pipe elbow and the suction pipe are used. After a period of time, it is also possible to wear holes to cause ash leakage. Therefore, if too much dust is found, the above parts should be inspected and treated in time.
4.7. Motor Incompetence and Overheating The motor weakness may be due to a phase disconnection in the three-phase circuit of the motor. The overheating of the motor may be due to short circuit of the internal circuit of the motor or long-term overload operation. At this time, stop the machine in time, ask the electrician to check the electrical equipment or adjust the workload.
4.8. The reason why the pellet machine does not discharge may be:
4.8.1. If the feed port and the agitator are clogged, the blockage should be removed in time;
4.8.2. If the die hole is blocked, the die hole should be opened;
4.8.3. If the moisture content of the raw material is too high or too low, the amount of steam should be adjusted;
4.8.4, the gap between the stamper and the press roller is too large, and the gap should be adjusted to meet the requirements.
4.9. The reason why the signal light on the analog screen does not light may be:
4.9.1. If the leveler is damaged, the new leveler should be replaced;
4.9.2 If the material level circuit is in poor contact, the line should be inspected and processed;
4.9.3 If the bulb is broken, the bulb should be replaced.
4.10. The reason for the significant decline in productivity may be:
4.10.1. If the hammer is worn, the hammer or angle adjustment should be replaced;
4.10.2, the screen hole is blocked, the screen hole should be cleaned;
4.10.3, the pressure roller wears, repairs or replaces the pressure roller;
4.10.4, the voltage drops, avoiding the peak of electricity consumption;
4.10.5. Insufficient supply of steam, check the pressure gauge, increase the amount of steam and pressure.
