Nowadays, the application of wood pellet machines is becoming more and more extensive, and there are more and more manufacturers producing wood pellet machines. So how to choose a good wood pellet machine? The following Kingoro granulator manufacturers will explain to you some methods of purchasing:
First, let’s first look at the quality of its appearance. Whether the spray paint on the surface of the wood pellet machine is uniform and firm, whether there is paint leakage, sagging and falling off, whether the surface polishing is bright, whether there is falling off and rusting, whether the surface of the stainless steel parts is smooth or not, whether there are bumps, and whether there are polished patterns .
Second, it is necessary to carefully check whether the body and the chassis, the motor (or diesel engine) and the chassis are fastened. The flat mode mainly checks whether the assembly quality of the template locking nut and the particle cutter is problematic, and the ring mode mainly checks the tightness of the template. Whether the bolts are tightened, and whether the pressure roller bracket is loose.
Third, whether there is a gap between the pressing roller of the ring die sawdust pellet machine and the inner wall of the ring die. After adjustment, tighten the adjusting nut in time and install the protective cover. After confirming that there are no foreign objects in the shield and the ring die, turn the ring die by hand to check whether the driven spindle is stuck and the sound of rubbing.
Fourth, observe whether there is beating of the ring die during rotation, and whether it will rub against other parts. Open the observation port for feeding the powder into the twisting cage and check whether there is any foreign matter in the twisting cage. Turn the cage shaft by hand to see if there is any rubbing noise.
Fifth, repeatedly open and close the ring-molded warehouse door to check whether it is easy to open and close and tightly closed. Special attention should be paid to the reliability inspection of the tightness and locking of the connection between the ring die pressing chamber and the powder feeding cage. The general requirements are: accurate positioning, firm locking, and no leakage of powder. After locking the press chamber door, observe the seam seal of the chamber door from the side. If there is a place where the seal is not tight, the fixing bolts of the door hinge of the warehouse can be adjusted so that it can effectively prevent the leakage of powder.
Sixth, adjust the different positions of the particle cutter, and lock the nut repeatedly to check whether its function is reliable.
Seventh, check its safety. When purchasing, you must carefully check whether the convex edge of the spindle safety linkage can effectively touch the fork of the travel switch. If the fork cannot be turned or not turned in place, the travel switch cannot be guaranteed to work effectively, and the user cannot purchase it; Regardless of the transmission mode used by various types of machines, the transmission components such as pulleys, transmission shafts, flanges, etc. must be equipped with special and effective protective covers. This kind of protective cover requires firm installation and can effectively protect the safety of operators.
Eighth, test machine inspection. Before testing the machine, first check the lubrication of the reduction gear box and the lubrication points in the machine. When starting the test machine, be sure to be ready to stop at any time. The time for the first start-up test machine should not be too long. After confirming that there is no abnormality in the machine, make the machine enter the continuous operation state. When the wood pellet machine is idling, there will be no irregular vibration, the impact sound of the gear and the friction between the feeding winch and the stirring shaft
Ninth, finished product inspection. Check whether the surface of the pellet feed is smooth, whether the section is neat, and whether there are cracks. It has a certain surface hardness, it is difficult to crush it by hand, and the specifications of the finished product should be uniform. The finished product qualification rate of pellet feed shall not be lower than 95%.、
