High purity quartz sand air classifier with high accuracy and fine powder?2025-12-02The airflow classifier is the core equipment for fine processing of high-purity quartz sand (SiO ₂ ≥ 99.99%), responsible for screening products in a specific particle size range of 100-500 mesh (with a required particle size deviation of ≤± 5% and a fine powder carryover rate of ≤ 2% in coarse powder), directly determining the quality of raw materials in high-end fields such as quartz glass and semiconductor packaging. If there is a drift in grading accuracy (particle size
Poor mixing and slurry layering in quartz crucible planetary mixer?2025-12-01The planetary mixer is the core equipment for the production of quartz crucibles, responsible for mixing high-purity quartz powder, binders, dispersants and other raw materials into a uniform slurry (requiring a mixing uniformity of ≥ 99% and no obvious layering after 24 hours of standing), which directly affects the density, strength and high temperature resistance of the crucible. If there is uneven mixing (local quartz powder agglomeration) and
Poor particle size and excessive crushing of vertical fracturing sand crusher?2025-11-29Vertical crusher is the core equipment for fine crushing in fracturing sand (quartz sand/ceramic sand), responsible for processing raw materials into particles with a mesh size of 20-70 that meet the fracturing requirements (particle roundness ≥ 0.8, over crushing rate ≤ 5%), directly affecting the diversion capacity of fracturing construction. If there is
Does the feldspar permanent magnet drum magnetic separator have impure iron removal and magnetic field attenuation?2025-11-29The permanent magnet drum magnetic separator is a key equipment for feldspar beneficiation and purification. Its core function is to remove magnetic impurities such as Fe ₂ O3 and Fe Ⅲ O ₄ from the raw materials (with a required Fe ₂ O3 content of ≤ 0.1% in the finished product), which directly affects the whiteness of feldspar and the quality of subsequent ceramic and glass products. If the iron removal is not thorough (iron content exceeds 0.2%) and the magnetic field strength decays quickly (
Does the ceramic fracturing sand granulator have poor ball formation and low strength?2025-11-27The ceramic fracturing sand granulator is the core equipment for high-end fracturing sand production, responsible for processing raw materials such as clay and bauxite into spherical particles (with a required sphericity rate of ≥ 92% and compressive strength of ≥ 69MPa), directly determining the service performance of fracturing sand in high-temperature and high-pressure
Is the classification of the plate sand vortex powder selector inaccurate and there is too much coarse powder?2025-11-27The vortex type powder selector is a key grading equipment in the production of sheet sand, responsible for screening high-quality fine powder with a mesh size of 100-200 (requiring a coarse powder carryover rate of ≤ 3%), which directly affects the fineness and coating effect of the sheet sand. If there is poor grading accuracy (pass rate of qualified particle size is less than 90%) and a high amount of coarse powder carryover (>100 mesh coarse powder accounts for more than 8%), it will cause t
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
