What should I do if the drum screen body deviates and the supporting wheel wears out quickly?2026-10-28After running for a period of time, the cylinder of the drum screen deviates, which is a problem encountered by many customers. The cylinder rotates with one side high and the other low, resulting in uneven distribution of material on the screen surface. The wear rate of the supporting wheels is significantly accelerated, and in severe cases, abnormal noise is produced due to friction between the cylinder and the frame. The problem usually lies in the adjustment of the idler and the levelness of
Will damage to the insulation layer of a single drum dryer lead to increased energy consumption?2026-10-27During the operation of a single drum dryer, the surface temperature of the drum is too high, causing it to become too hot to stay when touched by hand, which is an energy consumption problem encountered by many customers. The heat should have been used to dry the material, but a large amount is lost from the cylinder wall, causing fuel consumption to increase, but the moisture content of the discharged material cannot be reduced. The problem usually lies in two aspects: the insulation layer and
What is the reason for the abnormal noise of the cleaning machine reducer?2026-10-26Periodic abnormal noise from the reducer during the operation of the scrubbing machine is a potential equipment hazard encountered by many customers. The sound gradually changes from a slight "clang" sound to a piercing metal friction sound. If not dealt with in a timely manner, the gear or bearing of the reducer will be damaged, and the entire cleaning machine will be forced to stop. The replacement of the reducer may take one or two days, or three or five days, directly affecting the operation
How to determine if the dehydration screen vibration motor is overheated?2026-10-24The vibration motor is the power source of the dewatering screen, and burning is one of the most serious faults reported by customers. When the motor burns, the entire sieve stops, and replacement can take half a day or even a day, affecting the operation of the production line. The problem often lies in three aspects: heat dissipation, wiring, and operating load.
Why does the hanging iron remover lose its ability to absorb iron after prolonged use?2026-10-23The permanent magnet suspension iron remover is mounted above the belt conveyor and is responsible for removing iron filings and bolts mixed in quartz sand. After using it for one or two years, many customers found that the iron suction effect was not as good as before, and the iron parts above the belt continued to run downstream. After dismantling and testing, the magnetic field strength on the surface of the magnet was much lower than that of the new machine. The reason for the weakening of s
What will happen if the feed moisture content of the electromagnetic dry powder magnetic separator exceeds the standard?2026-10-22The electromagnetic dry powder magnetic separator is used for micro powder iron removal in quartz sand dry purification, but many customers overlook the indicator of feed moisture content. When the moisture content of the material exceeds the standard, the magnetic separator appears to be operating normally, but the iron removal effect is quietly decreasing, and the iron content of the finished product occasionally exceeds the standard.
What should I do if the surface temperature of the magnetic roller in the dry roller magnetic separator is too high?2026-10-21The problem of excessively high surface temperature of the magnetic roller in the dry iron removal process of quartz sand using a permanent magnet dry roller magnetic separator is easily overlooked. As the temperature of the magnetic roller increases, the magnetic force of neodymium iron boron magnetic material gradually decreases, and the iron removal effect quietly decreases, and this attenuation is often irreversible. The problem usually lies in two aspects: heat dissipation of the magnetic r
What should I do if the mud content still cannot be reduced after scrubbing with the scrubbing machine?2026-10-20The scrubbing machine is responsible for removing surface clay and iron film in the quartz sand production line, but many customers have reported that the mud content of the sand material is still high after scrubbing, which affects the subsequent magnetic separation and flotation effects. The equipment is running normally and the impeller is not damaged, but the problem often lies in the coordination of three process parameters: scrubbing time, scrubbing concentration, and feed particle size.
What is the reason for the decreasing processing capacity of the drum screen?2026-10-19Drum screen is commonly used in the pre grading process of quartz sand, but after running for a period of time, the processing capacity gradually decreases, and the same amount of feed cannot be screened, resulting in a large amount of unfiltered fine powder mixed in the finished product. The problem usually lies in two aspects: clogged sieve holes and cylinder rotation speed.
How to extend the service life of the three pass dryer for copying boards?2026-10-17After running the three return drum dryer for one or two years, many customers have found that the drying effect has significantly decreased - despite the same hot air temperature, the moisture content of the discharged material is higher than before, and there are often "wet lumps" at the tail of the drum that have not been dried. The heat source and speed are both normal, but the problem often lies in the reading board.
