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.
Why can't the moisture content of the dehydrated material always decrease?2026-10-16The vibrating dewatering screen is responsible for reducing moisture in the quartz sand wet production line, but many customers have found that the screen surface has serious water leakage - water does not leak out of the screen holes, but instead flows away from the discharge end along with the sand, resulting in a high moisture content in the finished product and a sudden increase in pressure during subsequent drying or packaging processes. The problem usually lies in the coordination of three
How much does the fineness of the feed affect the permanent magnet roller magnetic separator?2026-10-14Whether the feed particle size of the permanent magnet dry roller magnetic separator in quartz sand dry iron removal is within the equipment design range directly determines the iron removal effect. Many customers have found that the iron content in finished products fluctuates between high and low, and they have been investigating and troubleshooting. The problem lies in the fluctuation of grinding or grading processes, which leads to the particle size of materials entering the magnetic separat
How to detect the decrease in magnetic field strength of a flat magnetic separator?2026-10-13The flat magnetic separator relies on magnetic plates to adsorb iron impurities in wet iron removal from quartz sand. After running for two to three years, many customers have found that the iron removal effect is not as good as before, and the iron content in the concentrate gradually exceeds the standard. Using a Gaussian meter, the magnetic field strength on the surface of the magnetic plate has decreased significantly compared to the new machine. Magnetic demagnetization is a problem that pe
