Is the sieve of the swing screen classifier frequently clogged? The main reason is that the moisture content of the feed exceeds 5%2026-08-20Frequent clogging of the screen mesh and large deviation in grading accuracy are the two most frequently reported issues by customers. The root cause often lies not in the screening machine itself, but in the issues with the feed humidity and screen selection.
Does the magnetic field strength of the permanent magnet drum magnetic separator decay quickly?2026-08-19The permanent magnet drum magnetic separator is the main equipment for removing iron from quartz sand. Many customers have reported that the iron removal effect has significantly declined after half a year of operation, and the Fe ₂ O3 content has rebounded from below 0.05% to above 0.1%. The problem usually does not lie in the magnetic material itself, but in two easily overlooked maintenance details.
How to repair uneven discharge of quartz sand impact crusher2026-08-18The impact crusher is a commonly used equipment for coarse and medium crushing of quartz sand, responsible for crushing the raw stone into uniform sand material. After long-term operation of the equipment, it is easy to encounter problems such as uneven discharge sizes and uneven crushed materials, which seriously affect the quality of subsequent screening and sand production.
Low recovery rate and high consumption of reagents in flotation machines?2026-08-17The flotation machine is used for the separation of quartz sand from silicate impurities such as feldspar and mica. The two most troublesome problems for customers are low recovery rate and high reagent consumption. Many companies only focus on the drugs themselves, but overlook two more fundamental factors.
Is the feeding of the vibrating feeder unstable and fluctuating?2026-08-15The vibrating feeder is the "throat" of the quartz sand production line - it evenly feeds the material into the crusher, mill or screening equipment, and unstable feeding directly leads to fluctuations in all subsequent processes. The three most frequently reported issues by customers are fluctuating feed rates, abnormal equipment amplitude, and material slippage on the tank.
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%.
