What should I do if there is air leakage at the inlet and outlet of the three return dryer?2026-09-17After running for a period of time, the sealing failure at the inlet and outlet ends of the three return drum dryer has caused air leakage, which is a concern for many customers. Hot air runs away from the gaps, fuel consumption increases, but the moisture content of the discharged material cannot be reduced, and the dust on site also increases significantly.
What should I do with the adhesive material on the magnetic roller of the permanent magnet dry roller magnetic separator?2026-09-16The surface sticking of the magnetic roller is a common problem in the dry iron removal of quartz sand using a permanent magnet dry roller magnetic separator. When the moisture content of the material is too high or there is too much fine powder, the fine powder will gradually adhere to the surface of the magnetic roller, forming a layer of material shell, shielding the magnetic field lines, and significantly reducing the iron removal effect.
What should I do if the electromagnetic iron remover unloads iron uncleanly?2026-09-15The electromagnetic suspension iron remover is used in quartz sand production lines to remove iron filings from materials above the belt. However, when the power is turned off to unload iron, the iron filings remain and adhere to the magnetic poles, which is a common problem. The thicker the iron filings accumulate, the magnetic force is shielded, and the iron absorption effect decreases accordingly.
How to check the decrease in magnetic force of permanent magnet iron remover?2026-09-14The permanent magnet suspension iron remover is installed above the belt conveyor to remove mechanical iron such as iron filings and bolts mixed in quartz sand. But many customers have reported that the iron absorption effect of the equipment has significantly decreased after a period of use, and iron impurities above the belt still run downstream. The problem usually lies not in the magnetic block itself, but in the suspension height and material layer thickness.
What is the reason for the poor iron removal effect of permanent magnet dry roller magnetic separator?2026-09-12The permanent magnet dry roller magnetic separator is used for fine powder iron removal in quartz sand dry purification, but many customers have reported that the iron removal effect significantly decreases after the equipment runs for a period of time, and the iron content in the finished product exceeds the standard. The problem often lies not in the magnetic roller itself, but in the matching between the magnetic roller speed and the feeding speed.
How to check the decrease in screening efficiency of the drum screen?2026-09-11Roller screen is commonly used in the pre classification stage after quartz sand crushing, but after running for a period of time, the screening efficiency drops sharply from the design value of over 85% to below 60%, and a large amount of fine or coarse particles that should have been screened out are mixed in the finished product. The root cause of the problem is mostly due to clogged sieve holes.
Single drum dryer dries slowly and has a high moisture content2026-09-10Single tube dryers are commonly used in the quartz sand drying process, but many customers have reported that the drying speed slows down after running the equipment for a period of time, and the moisture content of the discharged material cannot be reduced. The problem usually lies in three aspects: heat source, plate reading, and speed.
What is the reason for the decrease in processing capacity of the vertical ring magnetic separator2026-09-09The vertical ring high gradient magnetic separator is indispensable in removing iron from quartz sand, but many customers have found that the processing capacity of the equipment decreases significantly after running for a period of time. The same opening of the feeding valve resulted in nearly one-third less discharge. The problem mostly lies in the media box.
How to deal with abnormal noise during the operation of permanent magnet drum magnetic separator2026-09-08The sound of the permanent magnet drum magnetic separator is stable during normal operation. Once periodic impact or friction sounds occur, it is mostly due to internal problems. If abnormal noise is detected and the machine continues to operate without stopping, the magnetic block may further detach and jam the drum, or even damage the entire magnetic system.
Electromagnetic dry powder magnetic separator coil overheating and frequent shutdown2026-09-07The electromagnetic dry powder magnetic separator is used for deep iron removal of micro powder materials in quartz sand dry purification, but frequent shutdowns caused by coil overheating are a concern for many customers. As the temperature of the coil increases, the magnetic field strength decreases, greatly reducing the iron removal effect and even burning the coil in severe cases.
