Does the filter cake of the filter press have high moisture content and low filtration efficiency?2026-08-03The filter press is a key equipment for tailings dewatering in quartz sand wet production lines. The two most common problems are high moisture content in the filter cake (over 25%) or low filtration efficiency (less than 50m ³/h). It is recommended to check the three stages in sequence during the investigation.
Is the dewatering screen broken quickly and has poor dewatering effect?2026-08-01In the quartz sand production line, the vibrating dewatering screen is responsible for the key tasks of solid-liquid separation and reducing moisture content. Many customers have reported frequent screen replacement and high moisture content in dehydrated sand. The problem often lies not in the screening machine itself, but in the feeding concentration and screen selection.
Does the impeller of the quartz sand scrubbing machine wear out quickly? Adjust the material and concentration in this way2026-07-31The CX scrubbing machine is used in quartz sand production lines to remove iron films and clay on the surface of sand particles, and the impeller is the core vulnerable part of the equipment. Many customers have provided feedback that the service life of the impeller is less than three months, or even shorter. Frequent replacement not only increases the cost of spare parts, but also affects the operation rate of the production line. The reason for this is mostly related to improper selection of
Common faults and troubleshooting ideas in the operation of vertical high gradient magnetic separators2026-07-30The vertical ring high gradient magnetic separator is a key equipment for deep iron removal from quartz sand, which can effectively remove weak magnetic impurities such as magnetite and hematite. However, in actual production, problems such as magnetic medium blockage, coil overheating, and fluctuations in iron removal efficiency often occur, directly affecting the quality of finished products and production line operation rate. Based on common on-site fault phenomena, the troubleshooting ideas
Troubleshooting and Solutions to Common Problems in Quartz Sand Production Line2026-07-29The quartz sand production line consists of multiple stages such as crushing, screening, grinding, magnetic separation, grading, and dehydration. Any problem in any stage may affect the yield and quality of the final product. Based on actual feedback from frontline production, the following issues are the most common and easily overlooked.
Which type of magnetic separator should be used for quartz sand with different particle sizes? The selection comparison table has arrived2026-07-28Magnetic separation is the most widely used method for removing iron in the purification process of quartz sand. However, in actual production, many customers have reported that the magnetic separation effect is not ideal, and the problem often lies in the mismatch between equipment selection and material characteristics. The existence state of iron impurities directly determines which magnetic separation equipment should be used.
New scheme for dry purification: color selection+grading+modification fully completed2026-07-24In the field of deep processing of quartz sand, dry purification and fine grading processes are increasingly widely used in water scarce areas and powder processing scenarios due to their advantages of not requiring water, not producing wastewater, and compact processes. Shanlu Heavy Industry provides a complete set of dry process equipment from crushing, color selection, grading to modification, suitable for the production of high-purity quartz sand, electronic grade silicon micro powder, coati
Is the mud content in quartz sand too high? The scrubbing and desliming system is configured in this way2026-07-23Quartz sand sources often contain a large amount of clay minerals and surface iron films. If these impurities are not effectively removed at the front end, they will directly affect the separation efficiency of subsequent purification processes such as magnetic separation and flotation. Shanlu Heavy Industry provides specialized production line equipment for scrubbing, desliming, grading, and concentration, suitable for pre-treatment of weathered sand, sedimentary sand, and quartz sand sources w
Can't feldspar mica be removed? This is the right way to match the flotation line2026-07-22Flotation is an effective purification method for impurity minerals in quartz sand that are embedded with fine particle size, have small differences in specific gravity, and are difficult to separate by magnetic or gravity separation. Shanlu Heavy Industry provides specialized production line equipment for quartz sand flotation, including slurry adjustment, dosing, flotation, and dehydration. It is suitable for quartz sand sources with high silicate impurities such as feldspar, mica, and tourmal
More than 90% of the water cycle! The wet production line plan for glass sand has arrived2026-07-14Float glass, photovoltaic glass, and daily-use glass have strict standards for the particle size, iron content, and chemical composition of quartz sand. Shanlu Heavy Industry provides specialized production line equipment for glass sand, including crushing, screening, grinding, magnetic separation, grading, and dehydration. It is suitable for the production of silica sand for glass in the 20-140 mesh range and meets the requirements for first grade float glass with Fe ₂ O3 content ≤ 120ppm and S
