  • Does the quartz sand drum dryer dry slowly and have a high moisture content?2025-11-17The drum dryer is the core equipment for quartz sand dewatering, responsible for drying sand particles with a moisture content of 15% -20% after washing to below 5% (industrial grade standard). If the drying efficiency is low (the unit time output is less than 60% of the rated value) and the moisture content of the finished product exceeds the standard (more than 8%), it will lead to subsequent screening blockage and product storage agglomeration. Based on practical experience, summarize a three
  • Does the quartz sand variable frequency feeder have low accuracy and large impact?2025-11-17The variable frequency feeder is the "precise feeding valve" of the quartz sand production line, which achieves stepless control of the feeding amount through variable frequency adjustment (requiring feeding accuracy error ≤ 5%). If the feeding accuracy is low (with an error of over 10%) and there is a large start stop impact (material spraying during startup and accumulation during shutdown), it will cause downstream equipment load fluctuations and uneven product quality. Based on practical exp
  • Is there much jamming or residue on the quartz sand screw conveyor? 3 steps to solve2025-11-15Spiral conveyor is the "material conveying link" of quartz sand production line, responsible for horizontal or inclined conveying of finished sand and raw sand. If there is a conveyor lag (stopping more than once per hour) or excessive material residue (residual amount in the machine exceeding 5%), it can lead to material breakage and
  • Does the quartz sand pulse bag filter have poor dust removal and clogged filter bags?2025-11-15The pulse bag filter is the "air purifier" of the quartz sand production line, responsible for capturing the dust generated during the crushing and screening process (with a required emission concentration of ≤ 10mg/m ³). If the dust removal efficiency is low (emission concentration exceeds 30mg/m ³) and the filter bag is prone to clogging (needs to be replaced after one month of use), it will cause dust
  • Is the grading of quartz sand air separator inaccurate and fine powder running?2025-11-12The wind separator is the core equipment for dry classification of quartz sand, which separates sand particles of different sizes (such as fine powder and coarse sand below 200 mesh) through airflow. If there is poor grading accuracy (pass rate of qualified particle size is less than 85%) and excessive fine powder carryover (the proportion of fine powder in coarse sand exceeds 10%),
  • Is the quartz sand magnetic separator not clean enough for iron removal and has a declining magnetic field?2025-11-12Magnetic separator is a key equipment for quartz sand purification, responsible for removing magnetic impurities such as Fe ₂ O Ⅲ from raw materials (with a required iron content of ≤ 0.05% in the finished product). If the iron removal effect is poor (iron content exceeds 0.1%) and the magnetic field strength decays quickly (decays by more than 30% after six months of use),
  • Uneven feeding and old blockage of quartz sand vibrating feeder?2025-11-11The vibrating feeder is the "flow control valve" of the quartz sand production line, responsible for evenly feeding the crushing, screening, and grinding equipment. If there is uneven feeding (flow fluctuation exceeding 20%) and frequent blockage (more than 2 blockages per hour), it will cause downstream equipment to overload or idle, disrupting the production rhythm. Based on practical experience, summarize the three-step troubleshooting method to quickly restore stable feeding.
  • Low recovery rate of quartz sand fine sand recycling machine and turbid wastewater?2025-11-11The fine sand recycling machine is the "resource guardian" of the quartz sand washing production line, responsible for recycling 0.1-0.3mm fine sand from wastewater. If the recovery rate is low (below 85%) and the sand content in the wastewater is high (over 0.5%), it will cause waste of raw materials, sedimentation in the sedimentation tank, and increase the cost of dredging. Based on practical experience, summarize the three-step troubleshooting method to quickly improve the recycling efficien
  • Is the quartz sand ball mill grinding slowly and with poor particle size?2025-11-08The ball mill is the core equipment for ultrafine grinding of quartz sand. If the grinding efficiency is low (the output per unit time is less than 60% of the rated value) and the particle size of the finished product does not meet the standard (such as requiring a 200 mesh pass rate of 95%, but only 80% in reality), it will drag down the subsequent purification process and increase production costs. Based on years of operation and maintenance experience, summarize a three-step troubleshooting m
  • Is the water in the quartz sand dewatering sieve not completely removed and fine sand running away? 3 steps to solve2025-11-05Dehydration screen is a key equipment for reducing the moisture content and recovering fine sand after washing quartz sand with water. If the dehydration effect is poor (the moisture content of the finished product exceeds 15%) and the loss of fine sand is high (the loss rate of<0.1mm fine sand exceeds 8%), it will increase the drying load, waste raw materials, and affect subsequent storage and transportation. Based on extensive project experience, summarize a three-step troubleshooting method t
