Rake thickener beneficiation plant is common enrichment equipment. According to different transmission modes, it is divided into two types: central drive and peripheral drive. The density of the thickeners produced in China is less than 24 meters, which is the center transmission type; the diameter of 24 meters or more is the same side transmission type thickener. Due to the high rigidity of the truss, its diameter can be made larger, and the largest in the country is φ100 meters. Figure 9-4 shows the center drive 浓 thickener. It consists of a thick pool 7, a truss 5, a transmission device 2, a truss lifting device 3, a receiving cylinder 4, a discharging device 9, and the like. The cylindrical dense pool 7 is made of cement or steel plate, and the bottom of the pool is flat or slightly conical. At the upper edge of the pool wall, there is an annular overflow tank 6 for overflowing, and the concentrated slurry needs to flow into the receiving cylinder 4 in the center of the pool along the feeding trough on the truss, and the lower portion of the receiving cylinder is immersed in the thickened surface of the dense tank. under. A vertical shaft 8 is fixed in the center of the thick pool, and a cross-shaped truss 5 is fixed at the end of the shaft, and a scraper is arranged under the truss. The truss is 8° to 15° from the horizontal. The vertical axis is driven by the motor through a worm reducer. The concentrated material is discharged from the discharge device 9 in the center of the pool by the truss scraper, and the clarified overflow water overflows from the upper overflow tank 6. In order to prevent the cruciform truss from being twisted when the thickener is under overload, the truss lifting device 3 can adjust the height of the truss and is also equipped with an overload signal. Figure 9-5 shows the peripheral transmission thickener. It has a thick cylindrical construction of a reinforced concrete tank, which has a reinforced central column 1 in place of coagulation soil rake axis, with gold leaf rake annular metal seat in column 1, and the other end of the truss end bracket 2 The platform 5 is provided with a tractor (transmission device) 6 supported on the ring-pool track 4 laid along the upper edge of the pool wall, and the tractor is moved by the motor through the reducer to move on the ring-pool track 4. The slurry enters the thickener along the feed trough 8 fixed on the bridge 7, and the concentrated material passes through the conical leaves from the periphery into the conical portion below the central funnel, and is then sent away by the sand pump. Some large-scale concentrators in China use edge-driven thickeners. The main advantages of the thickener are simple structure, convenient operation, less power consumption, and high technical and economic indicators. The main disadvantage is that it has a large footprint and is not suitable for coarse-grained materials of 0.3 mm. Hydraulic Metal Baler is specially used to baling various scrap metal materials and compress them into rectangular, cylindrical, octagonal, etc. The metal scraps that can be processed include scrap metal materials, metal shavings, rotating scrap metal materials, scrap steel bars, scrap aluminum profiles, scrap metal home appliance shells, scrap car shells, etc. The main cylinder pressure of our hydraulic metal balers ranges from 63 tons to 2000 tons and is divided into more than ten grades. Customers can choose the appropriate type of metal BALER according to their needs. The size of the material box and the size of the bale of the metal baler can be designed and produced according to customer needs.
