Is the deviation of the iron unloading belt of the magnetic separator due to uneven tension or roller problem?2026-11-05In the wet iron removal process of quartz sand using permanent magnet drum magnetic separators, the deviation of the iron discharge belt is a problem encountered by many customers. After the belt deviates, one side is severely worn and the other side is suspended. The iron powder cannot be removed completely, and the edge of the belt makes abnormal noise due to friction with the frame. The problem usually lies in belt tension, roller adjustment, and drum parallelism.
Why is the bottom flow of the sedimentation machine sometimes thick and sometimes thin due to obstruction?2026-11-04The obstructed settling machine achieves particle size separation in wet classification of quartz sand by ascending water flow, and stable bottom flow concentration is a prerequisite for ensuring classification accuracy. But many customers have found that the bottom flow concentration fluctuates between high and low. When it is high, the discharge valve quickly blocks, and when it is low, it becomes as thin as water, which affects the subsequent pressure filtration or dehydration processes. The
Why does the hydraulic classifier run coarse when the front-end feeding fluctuates?2026-11-03The hydraulic classifier is commonly used in quartz sand wet production lines to process slurry from front-end grinding or scrubbing, and sudden increase in feed rate is a common operating condition. When the front-end equipment is adjusted or the buffering capacity is insufficient, a large amount of slurry flows into the classifier, causing overflow and coarsening, and the bottom flow becomes finer, resulting in an instant collapse of the classification effect. The root of the problem lies in t
What material is more wear-resistant for spiral blades in hydraulic classifiers?2026-11-02The hydraulic classifier has been running for about a year, and the outer edge of the spiral blades has noticeably become thinner, with a larger gap between them and the inner wall of the tank, resulting in a decrease in classification accuracy. Blade wear is a problem that cannot be bypassed by such equipment, but the speed of wear varies depending on how well the blade material, speed, and material level in the slot are controlled.
Why does the drum screen shake badly after being used for a long time?2026-10-31After running for two or three years, the shaking of the drum becomes more and more obvious, and there is a dull impact sound at the contact between the rolling ring and the supporting wheel, which also deteriorates the screening effect. The problem mostly lies in the wear of the rolling ring. The rolling ring is a force transmitting component between the cylinder and the supporting wheel. After wear and tear, the clearance increases, and the cylinder loses stable support during operation, resul
What is the appropriate size for the sieve holes of the drum screen to ensure screening accuracy?2026-10-30The drum screen is responsible for controlling the particle size in the pre classification of quartz sand, but many customers have reported that oversized coarse particles are often mixed into the screened products, or the fine powder that is sieved out is not thoroughly screened, resulting in significantly lower screening accuracy than required. The problem usually lies in the coordination of three aspects: sieve size, cylinder speed, and feeding uniformity.
Why do the side plate welds of the dehydration screen crack after prolonged use?2026-10-29The vibration dewatering screen operates continuously in the quartz sand production line, and the cracking of the screen frame is a serious structural failure. Cracks often occur at the side plate welds, crossbeam connections, or near the exciter mounting seat. If not detected in a timely manner, crack propagation may lead to the scrapping of the entire screening machine. The problems usually arise in three aspects: weld quality, stress concentration, and operating load.
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
