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
Is the quartz sand jaw crusher inefficient and the jaw plate grinds quickly?2025-10-30Jaw crusher is the core equipment for coarse crushing of quartz sand. If the crushing efficiency is low (production capacity below 70% of the rated value) and the jaw plate wears out quickly (service life less than 300 hours), it will cause the production line to stagnate and the replacement cost to increase. Based on practical experience, summarize the three-step troubleshooting method to quickly restore equipment performance.
Is quartz sand impact sand making machine of poor grain size and much returns? Steps to solve2025-10-27The impact sand making machine is the core equipment for shaping and finely crushing quartz sand particles
The spiral quartz sand washer is not clean, and the fine sand spills? Steps to solve2025-10-22The spiral sand washing machine is the key equipment for quartz sand desliming and purification. If the ore washing is incomplete (the mud content of finished product is over 3%) and the fine sand loss is large (the loss rate of fine sand<0.15mm is over 10%), the raw material will be wasted and the quality of finished product will not meet the standard. Combined with practical experience, the three-step troubleshooting method is summarized to quickly recover equipment performance.
Uneven particle size and reduced capacity of quartz sand cone crusher? Quick solution in 3 steps2025-10-20The cone crusher is the core equipment for fine and medium crushing of quartz sand. If the particle size deviation after crushing is large (qualified particle rate is lower than 80%) and the capacity drops sharply (lower than 70% of the rated value), the subsequent sand production load will be increased and the qualified rate of finished products will be low. Combined with years of operation and maintenance experience, the three-step troubleshooting method is summarized to help enterprises quick
