Is the fracturing sand airflow screening inaccurate or blocked?2025-11-25Airflow screening is the core grading equipment for fracturing sand production, responsible for screening products with precise particle size ranges such as 20-40 mesh and 40-70 mesh (requiring a particle size qualification rate of ≥ 98%), which directly affects the fracturing construction effect of oil and gas wells. If the screening accuracy is low (with a pass rate of less than 90%) and the screen mesh is frequently clogged (cleaned more than twice per hour), it will lead to product degradati
Is the classification of feldspar spiral classifier slow and there are many fine sand inclusions in the settling?2025-11-25The spiral classifier is a key grading equipment for feldspar beneficiation, responsible for separating fine mud and qualified sand particles in feldspar ore (with a requirement of -200 mesh fine particle content ≤ 8% in settling sand), providing high-quality raw materials for subsequent flotation purification.
Is the quartz sand ultrasonic cleaning machine unable to clean thoroughly and the sand particles are broken?2025-11-24Ultrasonic cleaning machine is a key equipment for fine purification of quartz sand. It uses ultrasonic cavitation effect to remove oil stains and mud film on the surface of sand particles (with a requirement of impurity residue rate ≤ 0.3% after cleaning), providing clean raw materials for high-end application scenarios. If there is
Uneven mixing and thick scaling of quartz sand mixing bucket?2025-11-24The mixing bucket is a key equipment in the quartz sand washing and purification process, responsible for thoroughly mixing sand particles with water (or chemicals) (with a required mixing uniformity of ≥ 95%), providing conditions for subsequent grading and impurity removal. If there is uneven mixing (local materials not mixed, insufficient reaction of reagents), severe scaling on the barrel wall (scale layer thickness exceeding 15mm), it will lead to a decrease in purification efficiency and a
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
