The GTGB permanent magnet high-field plate magnetic separator is a patented product developed and manufactured by Guote Mining Equipment. It features high-gradient, high-field strength magnetic separation. It integrates magnetic and gravity separation, enabling targeted separation of weakly magnetic minerals based on the ore’s distinct magnetic characteristics. It is widely used in the wet processing of non-metallic ores for iron removal and purification, and is particularly suitable for wet iron removal of non-metallic ores such as quartz sand and potassium-sodium feldspar. It also demonstrates excellent separation performance for weakly magnetic minerals such as hematite, limonite, specularite, siderite, manganese ore, and tantalum mud.

The GTGB permanent magnet high-field plate magnetic separator primarily consists of a channel steel frame, a lower trough, a magnetic support frame, a drive roller assembly, a plate magnetic system, a conveyor belt, a reduction motor, a feed box, and an automatic ore flushing device.

GTGB permanent magnet high field strength plate magnetic separator product advantages: (1) The magnetic system of this equipment is made of high-performance rare earth neodymium iron boron material, with a wide pole surface, a large number of magnetic poles, high magnetic induction intensity, and a large magnetic field gradient. The local maximum magnetic field can reach 15,000 gauss, which is close to the magnetic field strength of a high-gradient electromagnetic magnetic separator. (2) The magnetic system group adopts a flat plate arrangement structure, which has a larger magnetic field sweeping area than traditional magnetic separators and better iron separation effect. (3) The magnetic system mechanism and conveyor belt are both installed on an adjustable carrier. The horizontal angle of the carrier can be adjusted quickly and easily to control the flow rate of the slurry in the magnetic separation area, so as to better select the magnetic materials in the slurry. (4) The reduction motor of a well-known brand is used, which is reliable and durable. The conveyor belt can be adjusted in time according to the different material shapes of the magnetic materials in the slurry to achieve better iron removal effect. (5) The conveyor belt is made of high-strength and high-quality composite materials, with a long service life and obvious unloading effect. (6) The feed box adopts a double-layer perforated plate structure, which ensures smooth and uniform distribution of materials and a thin slurry layer. It is equipped with upper and lower high-pressure water automatic ore flushing devices. The upper ore flushing device is responsible for flushing the non-magnetic ore slurry mixed with the magnetic material, and the lower ore flushing device uses high-pressure water to flush the magnetic material particles attached to the conveyor belt.

The GTGB permanent magnet high-field plate magnetic separator operates as follows: ore slurry is fed into the feed box through an inlet pipe. After thorough dispersion, it is evenly distributed on the conveyor belt above the plate magnetic system. Under the influence of gravity, the slurry flows downward along the inclined conveyor belt. The non-magnetic slurry eventually flows into the non-magnetic slurry hopper in the lower trough. The high-intensity magnetic field, reaching up to 15,000 gauss, firmly attracts the magnetic material contained in the slurry to the conveyor belt. The motor drives the drive roller assembly, moving the conveyor belt and the magnetic material on it upward along the inclined direction. The magnetic material on the conveyor belt then enters the non-magnetic field area. Under the influence of gravity and high-pressure flushing water, the magnetic material and the flushing water flow into the magnetic slurry hopper in the lower trough.

The GTGB plate magnetic separator, used in conjunction with the GTLH vertical ring magnetic separator, can maximize the separation of fine-grained, weakly magnetic materials contained in the slurry. It is a core equipment for iron removal and impurity removal in non-metallic ore beneficiation.

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.

Designed and manufactured by Weifang Guote Mining Equipment Co., Ltd., the GTLH series vertical ring high-gradient magnetic separator is a high-performance, technologically advanced high-magnetic separation device renowned both domestically and internationally. It is widely used for the beneficiation of weakly magnetic minerals such as hematite, limonite, siderite, ilmenite, and wolframite, as well as for the iron removal and purification of non-metallic minerals such as quartz, feldspar, nepheline, and kaolin. It boasts excellent beneficiation performance, low energy consumption, minimal maintenance, high reliability, and robust adaptability to ore properties, resulting in an average operating rate exceeding 99%.

The GTLH vertical ring high-gradient magnetic separator primarily consists of a frame, lower core and discharge chute, lower yoke and magnetic columns, excitation coil and cooling system, upper core and yoke, non-magnetic swivel, magnetic media cartridge, feed hopper, rinse hopper, concentrate hopper, middling hopper, tailings hopper, concentrate flushing device, level hopper, swivel drive mechanism, pulsating mechanism, and electrical control cabinet.

The excitation coil of the GTLH vertical ring high-gradient magnetic separator utilizes high-quality conductors and a multi-layer, three-dimensional, cross-winding structure. The oil circuit is unobstructed and well-connected. The coil winding provides high mechanical strength, strong deformation resistance, high insulation strength, a large heat exchange area, and excellent heat dissipation. The excitation coil is immersed in cooling transformer oil and cooled by the forced flow of the cooling oil pump. The heated cooling oil is pumped to an external, high-efficiency plate heat exchanger. The heat is effectively dissipated through the radiator’s efficient fins, and the cooled transformer oil returns to the excitation coil system, beginning a new cycle of cooling. This cooling method offers rapid cooling, simple structure, easy installation, and a compact footprint. It truly achieves oil-water cooling, is highly efficient and energy-efficient, reduces coil temperature rise, and maintains a stable magnetic field. This method enables the excitation coil to generate a high-gradient magnetic field at low temperatures, with an induced magnetic field strength of up to 2.3 Tesla. The excitation coil is equipped with a comprehensive temperature protection system that displays the operating temperature of each coil in real time and features two-level over-temperature protection. If the temperature exceeds the limit, an alarm is triggered, cutting off the excitation current and placing the equipment into a protective mode.

The magnetic medium utilizes our company’s proprietary structure, ensuring excellent beneficiation performance. With a feed size of 1.2 mm and normal flushing water, the magnetic medium remains clog-free and has a long service life. The swivel drive mechanism utilizes an internationally renowned brand, ensuring stable operation and a long service life. Driven by the stroke box, the pulsating mechanism reciprocates, repeatedly flushing mineral particles adsorbed on the magnetic medium surface with slurry, effectively eliminating mechanical inclusions and improving concentrate grade. The pulsating stroke box utilizes a high-thrust, four-roller reciprocating mechanism, ensuring stable operation over long periods of operation and enhancing equipment availability. The tailings valve features a fluid-resistant design and a special wear-resistant material coating on the inner wall, significantly enhancing its wear resistance. The use of well-known low-voltage electrical components and PLC components ensures safe, reliable operation and a long service life. An advanced soft-start function prevents transient current shock to the coil. The system also features an advanced fault self-diagnosis system with remote assistance capabilities. In the event of a malfunction, fault information is immediately transmitted to the company’s customer service center.

The GTLH vertical ring high-gradient magnetic separator operates as follows: The ring rotates vertically, generating a high-gradient magnetic field within the magnetic medium. Slurry is fed through the ring through the gaps in the upper iron yoke. Magnetic particles in the slurry are attracted to the surface of the magnetic medium and carried to the top, where the ring rotates, to the non-magnetic area. Flushing water then flushes the magnetic material into the concentrate hopper, while non-magnetic slurry flows through the gaps in the lower iron yoke and is discharged into the tailings hopper.

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.
