The quartz sand screw conveyor is the core auxiliary equipment for material
transportation in quartz sand production lines, widely used for continuous
transportation of raw materials, semi-finished products, and finished sand
(suitable for quartz sand with particle size of 0.1-300mm). It requires stable
transportation efficiency, no material accumulation, and no leakage. Its
operating state directly connects various processes such as crushing, screening,
and drying, affecting the continuity of the entire production line. In actual
production, enterprises often face problems such as poor conveying, rapid blade
wear, body leakage, and motor overload, which not only affect production
efficiency but also increase operation and maintenance costs, and even pose
safety hazards.
Shanlu Heavy Industry, as a technology-based enterprise specializing in the
research and development, manufacturing, and service of complete sets of quartz
sand equipment, has been deeply involved in the industry for more than ten
years. It has a standardized production base, professional R&D and technical
service team, and can provide full process services for screw conveyor
selection, customized adaptation, installation and commissioning, operation and
maintenance training, and standardized spare parts supply. All products and
solutions strictly comply with industry safety, environmental protection, and
quality standards, and have solved the pain points in the conveying process for
dozens of quartz sand enterprises across the country, ensuring the continuous
and efficient operation of production lines.
Based on the common core pain points of quartz sand screw conveyors and
practical on-site experience, Shanlu Heavy Industry has developed a compliant
and practical optimization plan that can be directly implemented. The plan is
professional, rigorous, and without any exaggeration
1. Poor transportation: The core causes are uneven feeding, blade
entanglement of materials, and excessive inclination angle of the conveyor.
Optimization plan: Equipped with a variable frequency feeder to stabilize the
feed rate at 85% -90% of the equipment's rated value, avoiding material
accumulation caused by feed overload; Choose shaftless spiral blades or install
anti winding devices to reduce material entanglement. Shanlu Heavy Industry can
customize blade structures based on material characteristics; Reasonably adjust
the inclination angle of the conveyor and control it within 15 ° -20 ° to avoid
excessive inclination angle causing material to slide down and affecting
conveying efficiency.
2. Rapid blade wear: mainly due to insufficient wear resistance of the blade
material, high hardness of quartz sand, and sharp impurities in the material.
Optimization measures: Select high chromium alloy wear-resistant blades, perform
surface hardening treatment to improve wear resistance and extend blade service
life. Shanlu Heavy Industry can provide standardized wear-resistant blade spare
parts to ensure quick replacement; Install a grille impurity removal device
before feeding to screen out sharp impurities and reduce blade impact wear;
Regularly check the wear of the blades, adjust the blade clearance in a timely
manner, and avoid equipment failure caused by uneven wear.
3. Body leakage and motor overload: often caused by aging seals, worn
casings, and excessive conveying resistance. Disposal plan: Adopting a labyrinth
sealing structure, combined with high-temperature and wear-resistant seals, to
prevent material leakage. Shanlu Heavy Industry can provide customized sealing
solutions; Regularly check the wear of the inner wall of the casing, and install
wear-resistant lining plates when the wear is severe; Optimize the conveying
path, reduce material conveying resistance, and equip with overload protection
device. When the load exceeds the set value by 110%, it will automatically warn
and stop the machine to avoid motor damage.
In terms of daily operation and maintenance, Shanlu Heavy Industry provides
professional guidance: conduct daily inspections of equipment operation status,
blade wear, sealing condition, and conveying efficiency, and keep detailed
operation records; Clean up residual materials inside the casing every week,
check the tightening of blades, seals, and bolts, and replenish bearing grease;
Calibrate the feed rate and conveyor inclination angle monthly, and tighten
loose parts; Conduct comprehensive equipment maintenance every quarter, replace
aging seals, worn blades, and liners to ensure long-term stable operation of the
equipment.
Shanlu Heavy Industry focuses on the research and development of quartz sand
full process equipment and services. Based on the production line capacity,
conveying distance, and material characteristics of the enterprise, we can
provide customized screw conveyor adaptation and optimization solutions to help
enterprises improve conveying efficiency, reduce operation and maintenance
costs, and ensure production continuity. If your production line is facing
problems such as poor conveying of screw conveyors, rapid blade wear, or needs
