How to use wood pellet machine correctly

Raw material size and moisture control.

The raw material size of wood chips is within 6mm and the moisture content is between 10-15%. If the compressed particles are fluffy and there are many vertical cracks, the moisture content of the raw materials should be appropriately reduced. If the situation is severe, contact the manufacturer to replace the compression ratio with a higher compression ratio. Ring die mold; On the contrary, if the compressed particles are short, high temperature, and cross-cut, the moisture content of the raw material should be appropriately increased. If the car is frequently stuffed, the ring die mold with a lower compression ratio should be replaced.

Use and maintenance

1. Familiarize with the manual: Please read the product manual that comes with the machine before using this machine. Understand the performance, structure, use, daily maintenance and maintenance of the ZLG series wood pellet machine.

2. Trial operation: Before turning on the machine, check whether the screws of each part of the machine are tight, and then start the motor for a trial run, and observe whether the machine's rotation direction is the same as the logo and whether there is any abnormal sound.

3. Correctly adjust the gap between the mold rolls: adjust the gap between the mold rolls each time the equipment is turned on, by adjusting the tension bolts and tightening nuts. Specific operation steps: loosen the tension bolt tightening nut II, tighten the tension bolt tightening nut I, use a torque wrench to fasten the tightening nut and measure the torque to 55~60N.m. Let the hollow shaft rotate once, the pressure roller rotates at least 4/5 at the same time as the mold rotates, and then tighten the bolt tightening nut II forcefully.

4. Mold washing: Take 50 kg of chaff, 100 kg of fine sand, and 50 kg of engine oil and stir evenly, then turn on the machine, and continue to discharge and grind (via the grinding port) immediately after landing. Repeat the grinding several times until the template hole is smooth and all the material is discharged.

5. Preparation for shutdown: In the early stage of use of the new mold of the granulator, stop feeding before shutting down. After the material in the silo is processed, add oily material (moisturizing) through the grinding port and press it into the mold hole to keep the hole lubricated (Wet) so that it will not be blocked when it is used next time.

6. Particle control: The length of the particles can be adjusted to the extension length of the cutter on the material rack.

7. Discharge port (under the discharge cover, there are N discharge ports in the middle and upper part of the bearing chamber). The function of this port is to discharge the remaining material in the pressing chamber. If the remaining material is not discharged in time, it will damage the hollow shaft bearing and reduce it seriously. Its life, so the discharge port must be kept unblocked, and pay attention to the discharge situation during work. If blockage or poor discharge is found, use slender objects to clear the blockage. Never use metal objects when the machine is running. Use plastic, wood, bamboo, etc. instead, you can remove the steel pipe of the discharge opening when it is difficult to clean. (It is normal that no excess material is discharged 3 days before the operation of the new equipment)

Lubrication instructions and maintenance.

1. Before the main reducer is used, the medium-duty industrial gear oil L-CKC320 should be added to the gear box according to the oil mark position (refer to the following table according to the ambient temperature), and the main reducer gear, main bearing chamber and bearing lubrication are automatically supplied by an oil pump. For lubrication, the oil must be changed after about 300 hours of operation for the first time; after the first oil change, the oil must be changed every 2000-3000 hours of operation.
   

2.  The gear reducer is filled with oil according to the label. Generally, use 46# mechanical oil or special lubrication-2#, molybdenum disulfide-2# or ZL-2 lithium-based grease. When adding lubricating oil, the oil level The height should be in the middle of the oil mark or the oil indicator, and the lubricating grease should be 1/3 to 1/2 of the internal cavity volume of the reducer. It is not advisable to add too much grease to avoid mixing heat; 1 Lubricant replacement cycle : Lubricating oil must be changed for the first time after 300 hours of operation. When changing, the remaining dirty oil should be removed. After the initial oil change, the lubricating oil should be replaced every 3 months if the reducer works continuously for more than 10 hours a day; the lubricating oil should be replaced every 6 months if the reducer works less than 10 hours a day; 2 Grease replacement Cycle: Replace it every 6 months (only manual lubrication).

3. The lubrication of the motor bearing depends on the speed. Choose HTHS Great Wall grease for 2 poles, and HP-R Great Wall grease for 4, 6, and 8 poles. Check or compensate the grease every 3-6 months.

Mold adjustment:

1. Adjust the gap between the pressure roller and the mold: remove the feed cover, unscrew the hollow bolt of the lubricating oil pipe at the shaft end of the pressure roller, adjust the two tightening nuts on the front and rear of the pull bolt, so that the pressure roller shaft can be rotated to adjust the pressure roller After adjusting the gap between the assembly and the mold, tighten the hollow bolt to connect the lubricating oil circuit.

   Note: Before starting the machine, the pressure roller should be pressed against the mold as much as possible; when changing the mold or pressure roller, the pressure roller should be kept away from the mold as much as possible.

2. Replace the pressure roller assembly: remove the feed cover → remove the related pipes and fixing bolts on the shelf plate, first take out the tension bolts, the pressure roller adjusting sleeve, and the material dial, and then take out the shelf plate. Lift the hollow shaft directly (see the first note) for replacement.

3. Mold replacement: Repeat the first operation to keep the pressure roller away from the mold; loosen the bolts that fix the cover plate and the connecting pipes of the frame plate, and then take out the cover plate together with the material shifting system. At this time, put the pressure roller assembly Loosen and use the middle threaded hole to push out the taper block. There are three to four evenly distributed φ26 process holes on the bearing chamber under the mold. The mold can be lifted up from this hole with a jack, and the lifting hole on the mold is used to take out the It is replaced.

Precautions

1. The operator should be familiar with the instruction manual, be familiar with the performance, structure and operation methods of the machine, and perform installation, commissioning, use and maintenance according to the provisions of this instruction.

2. Hard (metal) debris should be removed from the processed materials to avoid damage to the machine and cause accidents.

3. During the processing, it is strictly forbidden for the operator to reach into the transmission part and the granulation cavity to prevent accidents.

4. Frequently check the wear of the mold press roller, and adjust, replace or repair if necessary.

5. If you need to check the pellet machine, you must cut off the power supply to ensure safety.

6. The motor must be installed with a ground wire to avoid accidents.
