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
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
