1) What is the reason for the abnormal noise of the pellet machine? What factors are mainly considered? Answer: 1. The raw material transportation is unstable, the feeding speed should be adjusted; 2. The deflection scraper wear causes uneven feeding, and should be replaced with a new scraper; 3. The pellet machine ring mold and the pressure roller are old and new, preferably the new ring mold is matched. New pressure roller; 4. The gap between the ring die and the pressure roller is not coordinated with the material produced, and the gap of the pressure roller is adjusted; 5. The reason of the pressure roller, the new or old pressure roller is used together or the pressure roller is worn and damaged; 6. The used The formula is more difficult to granulate, and the formula is adjusted appropriately; 7. The steam supply is insufficient or the pressure changes, check whether the steam line and the system pressure and the pressure reducing valve are normal; 8. There is debris in the granulating bin, and the granulating bin is removed. Internal debris; 9. Spindle bearing wear or damage, need to replace the bearing. (2) When the granulator is refueling, the operation method of the grease block and the easy failure, how to solve? A: When refueling the granulator, you must first turn off the gas and then move the grease block. First: When moving the grease block, it is inevitable that you will forget to turn off the gas. If there is any movement, please do not move it. Turn off the gas source before moving. Second; sometimes after the gas is broken, still can not move, then remove the hexagonal bolt in the middle of the grease block, separate the grease block to see two O-rings in the middle, then put the O-ring Good to reload, you can. Third: When the grease block is not facing the oil passage, the grease block is connected because the air pressure is too high, just remove the hexagon socket bolt in the middle of the grease block. (3) What is the instability of the granulator current? Answer: (1) improper adjustment of the gap of the pressure roller ring mold; (2) serious wear of the materializing knife and uneven material distribution; (3) excessive coarse powder in the semi-finished product or the return material (the classification sieve has damage phenomenon); 4) The raw materials and the added liquid and steam are not mixed uniformly; (5) the transmission belts are different in tension. (4) What should I do if the pellet machine does not start up? Answer: (1) Check if the power supply is normally energized; (2) Check if the safety pin is broken; (3) Check if the travel switch is in place; (4) Check if the particle machine door is closed. (5) What is the improvement phenomenon for the uneven surface of the granular material? Answer: 1. Properly control the thickness of the powdered feed, so that all raw materials can be fully softened during quenching and tempering. 2. For raw materials with more fiber, do not add too much steam to this formula because it is easy to be mixed with steam bubbles. (6) What are the reasons why the granulated granules are not tight enough and the powder is more? How to deal with it? A: Control the granulation output, increase the ring mode compression ratio, and adjust the formula as necessary. (7) Reasons for the color inconsistency of the pellets and solutions? Answer, control the amount of water added and the uniformity of mixing in the mixture. Control the quality of the ring mold such as the smoothness of the hole; control the fineness and uniformity of the material before granulation. (8) What is the reason why the pellets are bent and many cracks appear on one side? A: This phenomenon is usually caused when the particles leave the ring mold. When the position of the cutter is adjusted far from the surface of the ring mold and the edge is blunt, the particles are broken or torn by the cutter when they are extruded from the die hole. Instead of being cut, some of the pellets are bent to one side and many cracks appear on the other side. Improvement method: increase the compression force of the ring mold on the feed, that is, increase the compression ratio of the ring mold, thereby increasing the density and hardness value of the pellet material; crushing the feed material to be finer, if the molasses or fat is added, the molasses should be improved. Or the uniformity of fat distribution and control the amount of addition to increase the compactness of the pellets, to prevent the feed from becoming soft; to adjust the distance of the cutter from the surface of the ring mold or to replace the use of sharper cutting blades; The agent improves the adhesion inside the particles. (9) What should I do if the mold hole is severely blocked? Answer: 1. After immersing in oil, first press it with compound feed and observe the discharge condition. 2. Slowly feed the whole corn or fractured corn to observe the discharge; 3. Whole corn and oil After mixing the fine-grained sand, observe the discharge; 4. Drill the filler with an electric drill (improper operation will damage the die hole).
