Exactly how to prolong the working life of a pellet machine?<br>
Every machine has a certain working life. It depends on the putting on parts. In terms of pellet equipments, the using parts consists of roller, die (ring die or level die), bearing, and also gearbox, and so on the functioning life of a ring die is 800-1200 hrs, a flat die is 600-800 hrs, and also a roller is around 1000 hours. The working life is figured out by the product top quality, yet likewise affected by your making use of routines. Correct use and normal maintenance can prolong the working life of a pellet machine.



Feed the pellet machine with oil mix

Whenever when you complete pellet manufacturing, feed oil combinations (blended sawdust and also used oil) to the pellet equipment and also allow it operate for 1-2 minutes, then you can close down the equipment. After this process, the die openings are filled with oil blend and won't obtain blocked by the raw materials With this step, you can start making pellets straight the following time. It can not only conserve your time yet likewise prolong the working life of the pellet equipment.



However if you do not make use of the pellet equipment for over 1 month, you would certainly better obtain the oil combination in the die, or they would obtain set and also challenging to clean up. This is bad for later usage.



Control the pureness of basic materials.

Before beginning the machine, see to it there is no contaminants in the feed hopper. Yet don't put you hand into the receptacle when the pellet machine is running. If there is irregular noise in the feed hopper, you should close down the machine and also eliminate the contaminants, and begin it once again.



See to it there is no stones, metals, large timber obstructs in the raw materials. Problem permitting, install a Tublar Magnet or a RCYB on the feed receptacle to prevent steels entering into the pellet machine. Besides, you can utilize an automatic feeder to accomplish consistent feeding, so that the pellet production is much more smooth.



Control the moisture web content

Normally, the dampness web content of raw materials should be 10% -18%. If the dampness content is too reduced, the raw products will certainly be too tough. They will boost the power intake as well as the abrasion of the pellet equipment. On the other hand, resources with high moisture web content are hard to grate, which will increase the abrasion of the hammer mill. Besides, Journalism and rubbing in the pellet mill will heat up the raw products and create the dampness to vaporize. The evaporated moisture will mix with the timber powders and also block the holes on the die, thus lowering the pellet production.



Clean the elements routinely

The pelletizing process will certainly generate a lot timber dust, however the pellet machine are normally not outfitted with dust defense gadget. This requires us to clean up the roller, die, major shaft and also bearing regularly. Clear up the sawdust in ports, voids and screw holes, or they might trigger fracture of the parts.



If you don't make use of the pellet machine for long time, I suggest you to dispatch the components and also clear up the pellets inside the die and the sawdust attached to the mold and mildew surface area, incase they come to be rigid and tough to eliminate. On the other hand, the sawdust will certainly take in water and also accelerate the deterioration of the parts.



Oil the roller, shafts as well as gearbox

Before the very first time usage, include lubricate oil to the transmission, shafts and also bearings. In daily usage, you need to lubricate the roller and also main shaft every day, and lube the transmission every a fifty percent year. If the roller lacks oil, it will create damages to the bearing as well as roller shaft, even break down the pellet machine.



Choose ideal size of die


The hole size of the die is from 2.5-10mm, and also the 4mm, 6mm as well as 8mm is one of the most popular. The size of die is determined by the raw materials. If the holes are undersized, the pellet yield will be reduced as well as even no pellets appearing. Meanwhile, they will boost the stress in between the roller as well as die as well as reduce the functioning life of the pellet equipment. So you need to seek advice from the sales to select a suitable die



Readjust the clearance between the roller and die.

The roller and also die (flat die or ring die) is the core part of the pellet equipment. Their clearance affect the pelletizing result as well as the functioning life. The appropriate clearance is between 0.1 mm and also 0.3 mm. If the clearance is larger than 0.3 mm, the raw product layer will certainly be as well thick and lower the pellet yield. If the clearance is less than 0.1 mm, the abrasion of the roller as well as die will certainly raise, as well as influence the functioning life.



In flat die pellet machine, there are readjusting nuts on the 2 sides of the equipment body. Tighten them up as well as screw back for 15 ° -30 °. Maintain the two screws in well balanced placements. Then, you can attach the lock bolts. In ring die pellet machine , make sure the clearance between each side of the roller and also the ring die coincides. In other words, the roller and ring die must in the same axis, in case the eccentric roller cause abrasion to the ring die.



Place the pellet machine in completely dry areas

To secure the pellet equipment from damp, we require to place the pellet equipment in a clean, completely dry as well as aerated environment. The metal components are simple to get rust under moist condition, and the electrical motor will have faster way or electrical leak. richi pellet will reduce the working life of the pellet equipment.
