The construction of organic fertilizer plant should consider many factors, such as the sale of organic fertilizer market, the development prospects of organic fertilizer industry, organic fertilizer production raw materials, organic fertilizer production line equipment, organic fertilizer production line investment. After the plant is built, when organic fertilizer is put into production, the maintenance and maintenance of organic fertilizer equipment should be considered.
After a period of time, wear and failure will inevitably occur in the production equipment of organic fertilizer. Organic fertilizer production lines require all machines to work together. Some machine failures will certainly affect the progress of the entire production line. How to reduce equipment wear, reduce production failures, extend the life of organic fertilizer equipment is particularly important. This paper introduces the matters and maintenance should be paid attention to in the use of organic fertilizer production equipment.

Maintenance of organic fertilizer production process
The production process machines of organic fertilizer mainly includes fermentation, overturning, crushing, mixing, granulation, screening, drying, cooling, packaging. Mainly used in organic fertilizer equipment are: compost dumper, crusher, blender, granulator, sieve extension, dryer, cooler, packaging machine.
From the perspective of organic fertilizer production process, several important mechanical maintenance methods are highlighted.
Compost dumper
After use, remove residues and residues from the machine and surrounding area and add lubricant to the lubrication point. Check the amount of oil in the gearbox and fill with enough gear oil. Clean up the underwind material and keep it open. Check the contact of the contactors in the electronic control cabinet. If there is any damage, replace it immediately.
Crusher
Before using the crusher, you must check that the shape of the crusher is damaged and that the components are complete. Before the mill is plugged in, make sure that there is iron in the mill and manually turn the flywheel more than one turn. To ensure safety, it is strictly forbidden to move the knife by hand. Confirm that the grinder main turn correctly before the motor can be started into production.
The inner knife of the crusher has a different time of use. If there is wear, replace the blade promptly. When installing the tool, the rotary tool must be tightened. The factory runs for about 500 hours. Check the left and right main bearings and clean and lubricate if necessary. The grinder has a lot of work. Regularly check the tightness of the transmission triangle belt to ensure that the drive is smooth and reliable.
The crusher speed cannot be increased at will. When the crusher works with a higher power machine, attention should be paid to control the flow and make the flow uniform.
Mixer
Before starting, check that all bolts are loose. Large stones or iron blocks must not be carried in the mixture to avoid damage to the stirring blades. Check that the housing and deceleration oil surfaces are in place.
Sieve
In the process of screen operation, the wear situation should be checked regularly to see if the screen surface local wear and leakage, whether the screen surface screen wear and other than excessive deformation, thus affecting grading accuracy and screening efficiency. In the event of such a situation, the service should be stopped and serviced, the part of the wear is too large should be root handling digital filter machine
Granulator
In normal production, the uniformity of feed and the moisture content of raw materials should be ensured. Stop feeding before stopping, and stop the material in the standby body after the basic discharge. If necessary, the machine can be turned on for 2-3 minutes after shutdown and all materials in the body can be pushed out. If the machine is stuck or the electrical load is too heavy, pull it still, reduce the supply of materials and stop inspection in time, and clean the inner wall of the machine.
Dryer
Do not stop the air, do not add fuel to the furnace to avoid scratches. When the dryer is running, it is prohibited to remove the protective device. Mobile luminaires with voltages higher than 12 volts are prohibited when checking the stove and dryer.
Screening machine
During the operation of the screen, the wear condition shall be checked regularly to see whether the leakage is caused by the local wear of the screen surface, and whether the excessive deformation is caused by the wear of the screen holes on the screen surface, thus affecting the classification accuracy and screening efficiency. In case of the above conditions, the machine shall be shut down for maintenance, and the parts with excessive wear shall be treated with root digital filter
Granulator
In normal production, feed uniformity and moisture content of raw materials should be ensured. Stop feeding before shutdown, and stop after the materials in the standby body are basically discharged. If necessary, turn on the machine for 2-3 minutes after shutdown to push out all materials in the body. If the machine is stuck or the electric load is too large and cannot be pulled, the material supply shall be reduced and the inspection shall be stopped in time, and the inner wall of the machine shall be cleaned.
Dryer
It is forbidden to add fuel to the furnace without stopping air supply to avoid scratches. When the dryer is running, it is forbidden to remove the protective device. When checking the stove and dryer, it is forbidden to use portable lamps with voltage higher than 12V.
Organic fertilizer production line equipment
Regular inspection items of organic fertilizer production line
One. Do not shut down frequently to avoid overload operation of organic fertilizer equipment.
2。 The tires of new equipment are easy to loosen, so check them frequently.
3. Check the operation of the reducer of each motor. If there is any abnormal noise or heat, stop the machine immediately for inspection.
4. Check the wear condition of each bearing and replace it with excessive wear. If the bearing oil temperature rises, stop the operation immediately and check the cause.
5. Check whether the chain is loose, damaged or aged.
6. If it is necessary to stop production, the residual organic fertilizer raw materials in the equipment shall be cleaned to prevent the residual organic fertilizer in the equipment from aggravating the corrosion of the equipment, and the cleaning, moisture-proof, anti-corrosion and other work shall be done well. After shutdown, the equipment idles for 10-20 minutes every 1-2 days, so that it can be used normally when it is put into production again.
After the installation, commissioning and acceptance of the organic fertilizer production line, there will be no major problems in the basic operation mechanism and procedures of the equipment. In order to make the equipment continuously and stably meet the production needs, it is necessary to strictly implement the use requirements of the equipment, do a good job in daily maintenance, so as to better ensure the use efficiency and service life of the equipment, and obtain greater economic benefits for the manufacturer.
