Is the automatic weighing feeder feeding unstable?2026-08-14The automatic weighing feeder is a key equipment for accurately controlling the feeding amount in quartz sand production lines, and the fluctuation of feeding directly affects the stability of subsequent grinding and grading processes. The three most frequently reported problems by customers are the fluctuating feeding amount, belt deviation, and frequent material jamming at the silo mouth.
Has the production capacity of ceramic filter suddenly decreased?2026-08-13Ceramic filters are widely used in the dewatering of quartz sand concentrates, but many customers have found that the processing capacity of the equipment significantly decreases after several months of operation, resulting in thinning of the filter cake and an increase in moisture content. The problem is not with the filter itself, but with the inadequate cleaning and regeneration process of the ceramic plates.
Does the discharge of the sand making machine become coarse and the hammer head wears out quickly?2026-08-12Vertical sand making machines are commonly used in the quartz sand crushing and shaping process. After running for a period of time, the discharge particle size becomes coarser and the hammer head wears faster, which is likely due to the gap between the impact plate and the hammer head not being adjusted in a timely manner.
Is the inflation volume of the flotation machine not adjustable? Is the dosage incorrect? Take a look at these two points2026-08-11The flotation machine is used for the separation of quartz sand from feldspar and mica. Many companies have reported significant fluctuations in flotation indicators and high consumption of reagents. The problem often lies not in the equipment itself, but in the operational details of the two stages of aeration and reagent addition.
Common problems with screening equipment: solution for clogged holes in drum screens2026-08-10Drum screen is widely used in the pre classification stage after quartz sand crushing, but when the material moisture content is high, fine powder is prone to adhere to the inner wall of the screen hole, causing blockage, and the screening efficiency drops sharply from the design value of over 85% to below 60%.
Is the classification effect of hydrocyclones poor? Check these three parameters one by one2026-08-09Hydrocyclones play a dual role in grading and concentration in quartz sand wet production lines. The two most common problems are a decrease in grading efficiency, overflow and coarsening, or bottom flow pinching, which directly affect the operational indicators of subsequent magnetic separation and dehydration processes. The investigation should be carried out in the order of "pressure first, concentration then, structure".
Does the filter cake of the filter press have high moisture content and low filtration efficiency?2026-08-03The filter press is a key equipment for tailings dewatering in quartz sand wet production lines. The two most common problems are high moisture content in the filter cake (over 25%) or low filtration efficiency (less than 50m ³/h). It is recommended to check the three stages in sequence during the investigation.
Is the dewatering screen broken quickly and has poor dewatering effect?2026-08-01In the quartz sand production line, the vibrating dewatering screen is responsible for the key tasks of solid-liquid separation and reducing moisture content. Many customers have reported frequent screen replacement and high moisture content in dehydrated sand. The problem often lies not in the screening machine itself, but in the feeding concentration and screen selection.
Does the impeller of the quartz sand scrubbing machine wear out quickly? Adjust the material and concentration in this way2026-07-31The CX scrubbing machine is used in quartz sand production lines to remove iron films and clay on the surface of sand particles, and the impeller is the core vulnerable part of the equipment. Many customers have provided feedback that the service life of the impeller is less than three months, or even shorter. Frequent replacement not only increases the cost of spare parts, but also affects the operation rate of the production line. The reason for this is mostly related to improper selection of
Common faults and troubleshooting ideas in the operation of vertical high gradient magnetic separators2026-07-30The vertical ring high gradient magnetic separator is a key equipment for deep iron removal from quartz sand, which can effectively remove weak magnetic impurities such as magnetite and hematite. However, in actual production, problems such as magnetic medium blockage, coil overheating, and fluctuations in iron removal efficiency often occur, directly affecting the quality of finished products and production line operation rate. Based on common on-site fault phenomena, the troubleshooting ideas
