Is there a large error and data drift in the quartz sand online particle size analyzer?2025-11-21The online particle size analyzer is the core equipment for real-time quality monitoring of quartz sand production lines, responsible for dynamically detecting the particle size distribution of sand particles (with a required detection error of ≤± 2%), and providing data support for adjusting the crushing and sand making processes. If there is a large detection error (exceeding ± 5%) and fast data drift (deviation exceeding 3% within 1 hour), it will lead to production parameter adjustment error
Is the quartz sand automatic sampling machine inaccurate in sampling or stuck in old materials?2025-11-21The automatic sampling machine is a key equipment for quality control in quartz sand production lines, responsible for proportionally sampling finished or semi-finished sand samples (with a sampling representativeness error of ≤ 3%), providing accurate samples for quality testing. If the sampling representativeness is poor (the deviation between the test data and the actual data exceeds 5%) and the material is stuck frequently (more than 3 times per shift), it will lead to quality misjudgment an
Is the sealing of the quartz sand vacuum packaging machine loose and the measurement is poor?2025-11-19The vacuum packaging machine is a key equipment for the storage and transportation of quartz sand products, responsible for sealing and packaging the dried quartz sand (with a sealing peel strength of ≥ 3N/15mm and a measurement error of ≤± 2%). If the seal is not firmly sealed (prone to cracking during transportation) and the measurement deviation is large (exceeding ± 5%), it will cause the material to become damp, agglomerate, and increase losses. Based on practical experience, summarize a th
Does the quartz sand high-pressure roller mill have a low crushing ratio and grind the roller surface quickly?2025-11-19High pressure roller mill is an efficient equipment for fine crushing of quartz sand, which achieves material crushing through high-pressure extrusion (requiring a crushing ratio of ≥ 8:1). If the crushing ratio is insufficient (less than 5:1) and the roller surface wears out quickly (with a service life of less than 200 hours), it will lead to an increase in subsequent sand production load and soaring production costs.
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),
