The quartz sand roller press is the core equipment in the fine crushing
process of large-scale quartz sand production lines. It is mainly used to crush
the coarse crushed quartz sand particles (particle size 20-50mm) into 5-10mm,
providing suitable raw materials for subsequent sand making and grading
processes. It requires uniform discharge particle size, stable pressure, and
controllable crushing ratio. Its operational stability directly affects the
efficiency of subsequent processes and the grading quality of finished sand. In
actual production, enterprises often face problems such as large pressure
fluctuations in roller presses, coarse discharge particles, uneven wear of
roller surfaces, and abnormal equipment vibration, which affect the continuous
operation of production lines and product quality.
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, a professional R&D team, and a
nationwide after-sales technical service network. It can provide full process
services for roller press selection, customized optimization, installation and
commissioning, operation and maintenance training, and standardized spare parts
supply. All products and technical solutions strictly comply with industry
safety, environmental protection, and quality standards. It has provided roller
press related solutions to dozens of quartz sand enterprises across the country,
helping enterprises solve pain points in the fine crushing process and improve
production stability.
Based on on-site practical experience and the core pain points of the quartz
sand roller press, Shanlu Heavy Industry has developed a professional and
compliant optimization plan that is in line with production reality, without any
exaggerated statements and can be directly implemented:
1. Unstable pressure: The core causes are inaccurate pressure regulation of
the hydraulic system, excessive fluctuations in feed rate, and uneven force on
the roller surface. Optimization plan: Adopting an intelligent hydraulic control
system, accurately setting the extrusion pressure (controlled within 15-25MPa
according to the hardness of quartz sand), monitoring pressure changes in real
time, and controlling the deviation within ± 0.5MPa; Equipped with a variable
frequency feeder, the feeding rate is stabilized at 80% -90% of the rated value
of the equipment, ensuring that the material enters evenly between the two
rollers and avoiding pressure fluctuations caused by local overload; Regularly
calibrate the parallelism of the roller surface to avoid pressure imbalance
caused by uneven force distribution. Shanlu Heavy Industry can provide on-site
calibration services.
2. Coarse discharge particles: mainly caused by insufficient extrusion
pressure, severe roller wear, and high material moisture content. Optimization
measures: Based on the hardness of quartz sand and the target discharge particle
size, accurately adjust the extrusion pressure to avoid insufficient crushing
caused by insufficient pressure; By selecting high wear-resistant alloy roller
surfaces, the wear resistance performance is improved and the service life of
the roller surfaces is extended. Shanlu Heavy Industry can provide standardized
wear-resistant roller surface spare parts to ensure quick replacement; Strictly
control the moisture content of the feed to ≤ 5%, and add a pre drying process
when the humidity is too high to avoid material adhesion affecting the extrusion
effect.
3. Uneven wear of the roller surface and equipment vibration: often caused by
sharp impurities in the feed, loose anchor bolts, and untimely cleaning of the
roller surface. Disposal plan: Install a grid impurity removal device at the
feeding end to screen out sharp impurities and oversized particles, reducing
roller surface impact wear; Regularly tighten the anchor bolts of the equipment,
check the integrity of the shock absorber spring, and avoid abnormal vibration;
Establish a daily roller surface cleaning system, promptly clean up residual
materials on the roller surface after shutdown, avoid uneven wear, and extend
the service life of the roller surface.
Daily operation and maintenance standards, Shanlu Heavy Industry provides
professional guidance: conduct daily inspections of equipment operation status,
extrusion pressure, discharge particle size, and roller surface wear, and keep
detailed operation records; Clean the roller surface and feed inlet material
accumulation every week, inspect the hydraulic system and transmission
components, and replenish high-temperature and anti-wear lubricating grease;
Calibrate extrusion pressure and feed quantity parameters monthly, and tighten
loose parts; Conduct comprehensive equipment maintenance every quarter, replace
aging seals and worn parts, and ensure long-term stable operation of the
equipment.
