Coal spiral chute

Coal Spiral Chute Coal Spiral Chute 1. Overview Gravity beneficiation is widely used in the beneficiation of metallic and non-metallic minerals due to its low environmental pollution and cost. Fiberglass reinforced plastic chute is a type of gravity sorting machine, with a structural characteristic that the cross-section presents a cubic parabolic state, suitable for handling finer particle levels of -0.2MM. In the sorting step, there is no need to add water for flushing, and the fine, medium, and tailings are segmented at the tail end of the chute. 2、 The mineral mortar with uniform technical principles is slowly fed onto the surface of the rotating groove through the feeding chute installed at the end of the spiral groove head, and then sorted. The bottom of the spiral groove is equipped with a valve block type product selection groove, which divides the selected equipment into three categories according to grade along the radial direction. By adjusting the orientation of the valve block to change the cutting width of each product, the equipment gathering bucket allows the obtained variable mineral flow to converge and lead out. The change in slope of the curve on the transverse surface of the fiberglass chute is particularly applicable for the sorting of fine-grained materials. Coal Spiral Chute III. Advantages: 1. Stable, easy to operate, and with a large density range. 2. The material processing has a large production capacity, high concentration, and high recovery rate. 3. Small space occupation, low water consumption, simple structure, and no need for power. 4. Easy installation, easy operation, low investment, and fast efficiency. The coal spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a spiral groove, an equipment selection groove, a product gathering hopper, and a groove bracket (including a cross or triangular frame). The rotating groove connected by spiral blades is a key component. The rotating plate is made of fiberglass (fiber reinforced coal gangue), connected together by screws, and the spiral groove has a pre made wear-resistant layer on the selected surface. She has the advantages of being lightweight, sturdy, and durable consumables that are not easily damaged. Above the rotating groove, there is a multi tube feeding homogenizer for ore separation, which is simple and convenient to control. The sieving mineral containers are freely stacked on the cross (or tripod) of the support table. The evenly distributed mortar is slowly fed onto the surface of the rotating groove through the feeding groove installed at the head of the spiral groove, and sorting is carried out. The tail end of the spiral groove is equipped with a valve block type new equipment to obtain the groove. The selected new products are divided into three categories (or four types) according to grade along the radial direction. Change the cutting width of each new equipment by adjusting the orientation of the valve block. The new product gathering bucket is a concentric circular tube that allows the selected multiple ore streams to converge and lead out separately. The slope change of the cross-section and curve of the spiral concentrator is very suitable for the separation of fine particle materials. 5、 The use of a field spiral concentrator is suitable for processing 0.6-0.03MM and vein ores and minerals, but it is unfavorable for separation when the mud content is high. Currently, it has been widely used for processing iron ore, tungsten, tin ore sand, tantalum niobium, bay and riverside ore and placer gold. coal spiral chute
