MINERAL PROCESSING SOLUTION

Our company develops and manufactures a new type of high-purity quartz sand production line, the vertical plate sand production line. This line converts large quartz ore into high-purity quartz sand particles ranging from 4 to 120 mesh, meeting the high-purity quartz sand needs of various industries, including quartz plate, glass, ceramics, casting, and construction. This line offers high production capacity, high sand output rate, excellent purity, a simple and rational process structure, easy operation, low failure rate, low investment, and no dust pollution.

Process flow: Large pieces of quartz ore are conveyed to the crushing process through a belt conveyor. According to the characteristics of the quartz ore and the customer’s final requirements for the quartz sand particle size, 1-2 level crushing units will be set up. The crushing process breaks the large pieces of quartz ore into small particles, and then the particles are sent to the ore washing and desludging process through a belt conveyor. The ore washing and desludging process is mainly completed by a drum type ore concentrator. The quartz sand particles enter the drum of the ore washing machine. As the drum rotates, they are rolled, pushed, and rubbed. The dirt, fine sand and part of the oxide scale attached to the surface of the quartz sand particles are cleaned by the washing water. The clean quartz sand particles are discharged from the tail of the ore washing machine and stacked in the temporary storage yard through a belt conveyor. Use tools such as forklifts to put the naturally dehydrated quartz sand particles into the feeding hopper of the grinding process. A vibrating feeder is installed under the hopper to continuously and evenly unload the quartz sand particles in the hopper onto the belt conveyor. The belt conveyor uses a white conveyor belt to effectively avoid color pollution during the transportation process. The quartz sand particles enter the vertical sand making machine and are ground into quartz sand particles of 4 to 120 mesh by the equipment. Then they enter the feeding pit of the bucket elevator through the sand discharge port at the bottom. The quartz sand particles are lifted by the bucket elevator and transported to the screening and impurity removal process. The ground quartz sand particles first enter the drum screen for screening, and the finished quartz sand particles fall into the high-field strength magnetic separator for impurity removal. The remaining high-purity quartz sand particles are sent to the final particle size selection process by the bucket elevator. After joint selection by the linear vibrating screen, high-purity quartz sand particles of different specifications and sizes are respectively packed into finished product packaging. The entire quartz grinding, The screening and impurity removal and particle size selection processes are all carried out in a fully enclosed environment. The quartz sand dust generated is collected by the pulse bag dust collector and will not cause any dust pollution to the environment.

In response to the increasingly stringent quality requirements for quartz and feldspar concentrates in industries like glass and ceramics, Weifang Guote Mining Equipment Co., Ltd. has developed an energy-saving and environmentally friendly quartz and feldspar wet-process production line. Based on our company’s beneficiation equipment and centered around high-strength magnetic purification equipment, this line effectively removes fine-grained, weakly magnetic impurities from the raw ore, significantly reducing the content of weakly magnetic impurities like iron, titanium, and manganese in the concentrate, significantly improving concentrate quality. Furthermore, this line boasts high yields of high-quality concentrate, a high degree of automation, low power consumption, a stable and reliable process, recyclable production water, and zero dust production. This line not only meets the high-purity concentrate demands of traditional industries like glass products and building materials, but also provides high-quality quartz sand raw material for high-tech industries such as semiconductor materials, silica thin film materials, and optical fiber communication materials.

Weifang Guote Mining Equipment Co., Ltd.’s quartz sand and feldspar wet production line primarily operates as follows: First, based on the customer’s specific characteristics, such as particle size, hardness, and impurity content, one to three stages of crushing are selected to reduce the ore size. A vibrating feeder uniformly and quantitatively vibrates the bulky ore into a jaw crusher for initial crushing. The crushed ore then enters a cone crusher for further particle size reduction. The smaller ore pieces then fall into a vertical sand making machine for pre-grinding, ultimately producing granular sand that meets process requirements. A belt conveyor then lifts the ore into the grinding silo. A vibrating feeder located below the grinding silo evenly vibrates the sand into a high-frequency vibrating screen for initial screening. The larger particles that pass through the screen enter a ceramic ball mill for grinding. The ground raw ore pulp is transported to the desludging hopper through the slurry pump for the first desludging and impurity removal process. The raw ore pulp with mud and sand impurities removed passes through the lower part of the desludging hopper and enters the blocked settler for particle size classification. The equipment returns most of the raw ore pulp with unqualified particle size to the ceramic ball mill for re-grinding through the lower slag discharge port. The raw ore pulp with qualified particle size is transported to the thickening hopper for the second desludging and impurity removal process. The tailings are discharged into the tailings pond through the upper part of the thickening hopper, and the raw ore pulp enters the hydraulic classifier from the concentrate port at the bottom of the thickening hopper. Under the combined action of turbulence and gravity in the hydraulic classifier, the tailings are discharged into the tailings pond through the upper tailings pipeline. Qualified ore pulp enters the magnetic separation and impurity removal stage. First, the raw ore pulp enters the GTGB flat plate magnetic separator, which efficiently removes most magnetic impurities. The cleaned ore pulp then enters the GTLH high-gradient vertical ring magnetic separator. Under the extremely strong induction magnetic field of up to 20,000 gauss, the fine-grained, weakly magnetic impurities in the ore pulp are completely separated and discharged through the slag discharge pipeline into the tailings pond. The concentrate pulp is pumped into the thickening hopper by the slurry pump for concentration and dewatering. After initial concentration, the concentrate pulp enters the vibrating dewatering screen. Finally, the dried, qualified concentrate is sent to the finished product silo for packaging and shipment.

All tailings generated throughout the entire quartz and feldspar wet production line are collected and sent to the tailings treatment process. First, the tailings slurry is discharged into a thickening tank equipped with a thickener. After initial clarification, the processed water is discharged through an overflow trough. The concentrated tailings slurry settles to the bottom of the tank and is collected by thickening rakes and discharged at the central outlet. It is then pumped by a slurry pump to a ceramic filter for final dewatering. The microporous ceramic plates separate the tailings slurry into solids and liquids, and the separated water can be reused as processing water. The tailings slurry is then transported to the tailings dump via a belt conveyor.

Our company’s quartz and feldspar wet process production line features advanced equipment, mature technology, and high scalability, allowing for quick and easy process upgrades to meet customers’ increasing demands for product variety and quality.
