Slurry concentration control in spiral chute concentrator

Gravity beneficiation is widely used in the beneficiation of metal and non-ferrous metals due to its small environmental pollution and low cost. The fiberglass spiral chute is a type of gravity separation machinery, characterized by a cubic parabolic shape on the cross-section, suitable for handling finer particle levels of -0.2MM. In the selection process, there is no need to add flushing water, and fine, medium, and tailings are segmented at the tail end of the chute. 2、 The slurry with the same technical principle is slowly fed onto the surface of the spiral groove through the feeding groove installed at the head of the rotating groove for selection. The tail end of the rotating groove is equipped with a valve block type equipment to select the groove, allowing the sorted products to be divided into three categories according to grade along the radial direction. By adjusting the position of the valve block to obtain the width of each device, the product gathering hopper will differentiate and densely extract the intercepted multi-directional mineral flow. The cross-section of the spiral chute and the slope change of the curve are particularly suitable for the separation of fine particle materials. The concentration control of the ore slurry in the spiral chute beneficiation plant is three characteristics or advantages. 1. Heavy-duty and large processing capacity. Today, the overall requirement for treating ore materials is to establish profits on a large scale. 2. Fine granulation is used for the treatment of fine and micro particle level mineral materials, especially for minerals with a particle size of -0.047mm. The original machinery can basically ensure the recovery of+0.047mm particle size. 3. With the development of Hydraulics, two-phase flow, machine vibration, etc., spiral chutes have progressed from simple use of gravity and water resistance to the level of composite application of centrifugal force, equipment vibration force, magnetic separation force, etc. By using a composite force field, the enrichment of useful mineral materials and the separation of small and fine particles can be enhanced, thereby improving mineral recovery rate. 4. Based on energy conservation, environmental protection and consumption reduction, the land area and space occupied should be small, and water and electricity consumption should be small. 5. Easy and flexible operation, stable sorting process, simple structure, and convenient maintenance management. Spiral chute concentration control of ore slurry in the beneficiation plant is . The structure of the fiberglass spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a spiral groove, a product selection groove, an equipment gathering hopper, and a groove support (including a cross or triangular frame). The rotating groove connected by spiral blades is a key accessory. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together by screws. The spiral groove has a pre made durable wear-resistant layer on the selected surface. He also has the advantage of lightweight, sturdy, and long-lasting consumables. The rotating groove is equipped with a multi tube feeding homogenizer to evenly distribute the ore, and the operation is not complicated. The screening machine is freely stacked on a cross (or tripod) on a support table. The evenly distributed mortar is slowly fed onto the surface of the spiral groove through the feeding chute installed at the beginning of the spiral groove, and sorting is carried out. The bottom of the rotating groove is installed in a valve block type new product cutting groove, and the selected new equipment is divided into three types (or four categories) of new products along the radial direction according to grade. Change the width of each new product by adjusting the position of the valve block. The new equipment gathering bucket is a concentric circular tube that allows the selected multi head ore flow to converge and export separately. The cross-section of the spiral chute and the slope of the curve change greatly in the separation of fine particle materials. 5、 The fiberglass spiral chute is suitable for processing 0.6-0.03MM and vein or placer ores, but it is unfavorable for sorting when the mud content is high. Now it has been widely used for processing iron ore, tungsten, tin ore, niobium tantalum ore, coastal and riverside ore sands, and gold mines.
