Is the inflation volume of the flotation machine not adjustable? Is the dosage incorrect? Take a look at these two points2026-08-11The flotation machine is used for the separation of quartz sand from feldspar and mica. Many companies have reported significant fluctuations in flotation indicators and high consumption of reagents. The problem often lies not in the equipment itself, but in the operational details of the two stages of aeration and reagent addition.
Common problems with screening equipment: solution for clogged holes in drum screens2026-08-10Drum screen is widely used in the pre classification stage after quartz sand crushing, but when the material moisture content is high, fine powder is prone to adhere to the inner wall of the screen hole, causing blockage, and the screening efficiency drops sharply from the design value of over 85% to below 60%.
Is the classification effect of hydrocyclones poor? Check these three parameters one by one2026-08-09Hydrocyclones play a dual role in grading and concentration in quartz sand wet production lines. The two most common problems are a decrease in grading efficiency, overflow and coarsening, or bottom flow pinching, which directly affect the operational indicators of subsequent magnetic separation and dehydration processes. The investigation should be carried out in the order of "pressure first, concentration then, structure".
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
