Experimental spiral chute

Experimental spiral chutes 1. Overview: Gravity separation spiral chutes summarize the characteristics of spiral concentrators, spiral concentrators, shakers, and centrifugal concentrators. After being evaluated by relevant scientific research, design, universities, and concentrators organized by the Ministry of Metallurgy, they are recognized as having superior performance, advanced sorting indicators, and have been awarded the Science and Technology Research Achievement Award by the Ministry of Metallurgical Industry. They have been widely used in non-ferrous and black mining metals. This machine is suitable for separating fine materials with Granularity of 0.3-0.02mm to obtain iron, ferrotitanium, ferrochrome, pyrite, zircon sand, Rutile, monazite, phosphate rock, tungsten ore, placer tin ore, tantalum niobium ore, niobium ore and other non-ferrous metals, rare mineral metals and nonferrous metal mineral bodies with different specific gravity. 2、 Production principle: The spiral chute screening machine is freely placed on the cross (or tripod) on the support table. The uniform mortar is slowly fed to the surface of the rotating groove through the feeding groove installed at the beginning of the spiral groove, and the selection is carried out. The tail end is equipped with a valve block type equipment cutting groove, allowing the sorted products to be divided into three types (or four types) according to grade along the radial direction. Change the selection width of each equipment by adjusting the orientation of the valve block. The product gathering bucket is a concentric circular tube that converges and induces the obtained multi head ore flow. The cross-section of the fiberglass spiral chute and the slope of the curve change, which is very suitable for the separation of fine mineral materials. The spiral chute used in the experiment is characterized by stability, easy operation, and a large density range. 2. The material processing capacity is large, the enrichment ratio is high, and the probability of recovery is high. 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 experimental spiral chute is composed of six parts: a feeding homogenizer, a feeding groove, a rotating groove, an equipment cutting groove, a product gathering hopper, and a groove support (including a cross or triangular frame). The spiral groove formed by the connection of spiral plates is a key component. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and is bolted together. The selected surface of the rotating groove has a pre designed durable wear-resistant layer. It has the advantages of being lightweight, sturdy, durable, and not easily damaged consumer goods. The spiral groove is equipped with a multi tube feeding homogenizer to divide ore evenly, making it easy to operate. The concentrator is not limited to being placed on the cross (or tripod) of the support table. The evenly divided mineral mortar is slowly fed onto the spiral groove surface through the feeding chute at the head of the rotating groove for sorting. The tail of the rotating groove is installed in a valve type new product selection groove, and the selected new products are divided into three types (or four types) of new equipment along the radial direction according to grade. Change the width of each new product by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that allows the intercepted multi-directional mineral flow to converge and lead out. The cross section of the spiral chute and the different slopes of the curves are very suitable for sorting fine particle materials. 5、 The spiral concentrator is suitable for separating fine grained iron ore, Ilmenite, Chromite, pyrite, cassiterite, tantalum niobium ore, placer gold ore, coal, monazite ore, Rutile ore, zircon sand, rare earth ore and other metal and non-metallic mineral materials with sufficient density ratio difference.
