The quartz sand magnetic separation and purification machine is the core
equipment for the production of high-purity quartz sand (photovoltaic grade,
electronic grade), mainly used to remove weak magnetic impurities (such as Fe ₂
O3, TiO ₂) in quartz sand, ensure the purity of the finished sand (required iron
removal rate ≥ 97%, finished iron content ≤ 60ppm), and directly determine the
high-end application adaptability of quartz sand. In actual production, the
equipment often encounters problems such as inadequate iron removal rate,
unstable magnetic field strength, low sorting efficiency, and equipment jamming,
which are mostly related to improper adaptation of magnetic field parameters,
non-standard equipment maintenance, and insufficient raw material pretreatment.
There are clear and feasible disposal plans.
Shanlu Heavy Industry is a technology-based enterprise specializing in the
research and development, manufacturing, and service of complete sets of quartz
sand equipment. With more than ten years of experience in the industry, it has a
standardized production base, a professional R&D team, and a complete
after-sales system. It can provide full process services such as magnetic
separation and purification machine selection, parameter calibration, compliance
optimization, and operation and maintenance training. With rich on-site
practical experience, it formulates optimization plans that are suitable for
production situations based on common equipment problems, helping enterprises
achieve compliant production of high-purity sand. All plans comply with industry
standards and quality standards.
1、 Common problem troubleshooting
Based on the on-site service experience of Shanlu Heavy Industry's technical
team, common problems with magnetic separation and purification machines can be
accurately identified to avoid blind maintenance. Firstly, the iron removal rate
does not meet the standard, which is often caused by insufficient magnetic field
strength, insufficient contact between materials and magnetic fields, and
excessive impurity content in raw materials. This can be investigated by
detecting magnetic field strength and adjusting feed speed; Secondly, the
magnetic field is unstable, mainly due to loose magnetic systems and poor
equipment heat dissipation. After long-term operation, it is necessary to
regularly check the fixing of the magnetic system; The third issue is low
sorting efficiency, which is often related to uneven feeding and unreasonable
sorting gaps; The fourth issue is equipment jamming, which is caused by impurity
blockage and insufficient lubrication of transmission components.
2、 Compliance Optimization Guidelines
1. Non compliant iron removal rate: precise adaptation to improve impurity
removal effect
According to the impurity content of quartz sand raw materials, accurately
adjust the magnetic field strength (suitable for weak magnetic impurities of
12000-18000Gs), regularly calibrate with a magnetic field detector to ensure
stable strength; Optimize the feeding system, control the feeding speed
(0.6-1.0m/s) through variable frequency speed regulation, install a material
distributor to evenly distribute the material, and extend the contact time
between the material and the magnetic field; Pre treat the raw materials, screen
out oversized impurities, and avoid affecting the sorting effect. Shanlu Heavy
Industry can provide suggestions for adapting the pre-treatment equipment.
2. Unstable magnetic field and low sorting efficiency: standardized
adjustment to ensure stability
Regularly check the fixing bolts of the magnetic system, tighten loose parts,
and avoid uneven magnetic field caused by magnetic system displacement; Optimize
the cooling structure of the equipment to ensure that the temperature is
controlled below 60 ℃ during operation, and avoid high temperatures affecting
the magnetic field strength; Adjust the sorting gap (5-8mm) to adapt to
different particle sizes of quartz sand, while cleaning residual impurities in
the sorting chamber to improve sorting efficiency; Equipped with an online
monitoring device, it provides real-time feedback on magnetic field strength and
sorting efficiency, making it easy to adjust in a timely manner.
3. Equipment jamming: Daily cleaning, standardized lubrication
After daily shutdown, clean the impurities and accumulated materials in the
sorting chamber, feed inlet, and discharge channel. Install a grid before
feeding to screen out impurities with a particle size greater than 0.5mm to
avoid blockage; Regularly add lithium based grease to the transmission
components of the equipment, every 500 working hours to ensure smooth operation;
Check the operation status of the motor and equip it with overload protection
device to avoid motor damage caused by jamming.
3、 Enterprise Services and Daily Operations
Shanlu Heavy Industry can provide customized adaptation services for magnetic
separation and purification machines based on the purity requirements and raw
material characteristics of the enterprise's finished products, with
