The quartz sand magnetic separator is the core equipment for purifying and
removing iron in high-purity quartz sand production lines (daily processing
capacity ≥ 3000t). It is mainly used to remove ferromagnetic impurities in
quartz sand (with a required iron removal rate ≥ 98% and iron content ≤ 0.05%),
and is suitable for high-end quartz sand production needs such as photovoltaics,
electronics, and glass. Its iron removal accuracy directly determines the grade
and market competitiveness of the finished sand. In actual production,
enterprises often face problems such as incomplete iron removal, substandard
production capacity, and rapid attenuation of equipment magnetic fields, which
affect product quality and production efficiency.
As a technology-based enterprise specializing in the research and
development, manufacturing, and service of complete sets of quartz sand
equipment, Shanlu Heavy Industry has been deeply involved in the industry for
more than ten years. It has a standardized production base, a professional
R&D and technical service team, and can provide full process services for
magnetic separator selection, customized optimization, installation and
commissioning, operation and maintenance training, and spare parts supply. All
products and solutions comply with industry safety, environmental protection,
and quality standards. With professional technical strength, it has helped
dozens of quartz sand enterprises across the country achieve efficient iron
removal and stable improvement of product quality.
Based on the common pain points of quartz sand magnetic separators, Shanlu
Heavy Industry has developed a targeted compliance optimization plan based on
on-site practical experience, which is in line with production reality and does
not exaggerate:
1. Incomplete iron removal: The core causes are insufficient magnetic field
strength, excessive material flow rate, and uneven feeding. Optimization plan:
Select a high magnetic field strength magnetic separator (magnetic field
strength ≥ 12000Gs) to meet the removal requirements of weak magnetic impurities
in quartz sand; By using a frequency conversion speed control system, the
material flow rate is controlled at 0.8-1.2m/s to ensure sufficient adsorption
of impurities; Equipped with a variable frequency feeder, the feeding rate is
stabilized at 85% -90% of the rated value of the equipment, and a fabric feeder
is installed to ensure that the material passes evenly through the magnetic
field area and improve the iron removal accuracy.
2. Insufficient production capacity: mainly due to mismatch between equipment
specifications and production line capacity, and improper adjustment of magnetic
field gap. Optimization measures: Based on the daily processing capacity of the
production line, accurately select magnetic separators that are suitable for the
specifications to avoid small equipment bearing large loads; Regularly calibrate
the magnetic field gap and control it within 5-8mm to avoid excessive gap and
reduce processing efficiency. Shanlu Heavy Industry can provide on-site
parameter calibration services.
3. Fast magnetic field attenuation: often caused by poor magnetic material,
inadequate equipment sealing, and dust intrusion. Optimization plan: Select
high-performance permanent magnets, control the magnetic field attenuation rate
to ≤ 5% per year, and extend the service life of the equipment; Adopting a
labyrinth sealing structure to prevent dust from entering the magnet and protect
magnetic field stability; Regularly clean the dust on the surface of the magnet,
test the magnetic field strength every quarter, and perform magnetization
maintenance in a timely manner.
In terms of daily operation and maintenance, Shanlu Heavy Industry recommends
following standardized procedures: conducting daily inspections of the operation
status, magnetic field strength, and iron removal effect of the magnetic
separator, and keeping operation records; Clean up the accumulated materials
inside the equipment every week and inspect core components such as magnets and
conveyor belts; Calibrate the feed rate and material flow rate monthly, and
tighten loose bolts; Conduct comprehensive equipment maintenance every quarter,
replace aging seals and worn parts, and ensure long-term stable operation of the
equipment.
