Eight, washing plant equipment configuration It is difficult to wash ore, the number of washing sections is large, and the operation line is long. Especially the production scale is large, the equipment specifications are also large, the weight is also large, and the floor space is also large. The equipment configuration should promote the material self-flow as much as possible. Layer configuration, suitable for establishing an independent washing plant. The basic points of the configuration are: the crushing, washing, sieving equipment , the cylinder washing screen, the washing vibrating screen and other equipment are set on the high-rise floor, the material under the screen is self-flowing to the lower platform scrubber, spiral classifier; The grit of the material and the scrubber and the spiral classifier is sent to the next operation by the belt conveyor according to the dissociation of the mineral monomer, such as crushing, grinding, jigging, etc.; the overflow is sent to the thickener by the rubber pump. The concentrator overflows as washing water, and the underflow is sent to the grinding by the sand pump. As shown in the figure below, the material is fed into the cylinder washing machine 1 by the horizontal belt conveyor 4 (hand-selected and removed mud group), and the under-slurry material flows to the lower-layer spiral washing machine 2, which is sanded and conveyed by tape. The material on the screen sieve sent by the machine 5 is transported to the subsequent operation by the collecting belt conveyor 7 , and the overflow of the 2 is flowed to the thickener, and the clarified water is used for washing the water and the bottom stream is used for grinding. Maintenance of electric bridge cranes 3. 6 except iron removed iron. The washing equipment configuration should take into account: Scrap Metal Baler And Shear,Industrial Metal Baling And Shearing Machine,Heavy-Duty Scrap Shear Baler Combo,Precision Metal Recycling And Shearing Machinery Jiangyin Hangli Technology Co., Ltd. , https://www.hanglimachinery.com
For easy or washable ore, vibrating screen and spiral classifier are the main washing equipment. The washing equipment and the crusher can be arranged in the same inter-span, and are arranged in a multi-step type according to the process sequence, which is characterized in that the material is self-flowing, the working line is short, and the floor space is small. As shown in the figure below, the coarse crushing ore is transported by the belt conveyor 1 to the medium crushing silo, and the washing machine 2 is fed into the washing machine 3, and the material is sieved into the medium crushing cone crusher 5, and the material is sieved. Entering the secondary washing sieve 4, the material on the sieve passes through the belt conveyor 13 and the medium crushed ore into the fine pre-screening machine (and the washing) 6, and the material on the sieve is fed into the fine cone crusher 7, which discharges and Spiral classifier 8 grit sharing mining belt conveyor is sent to the main plant grinding bin, 4 and 6 of the undersize material flows to 8; the spiral classifier overflows from the sand pump to the cyclone 10, and its overflow acts as The washing water of the washing sieve 3 is sent to the thickener 11 and the bottom stream is lifted by the sand pump 12 to the grinding. The clarified water of the thickener is lifted by the pump 9 to the washing screen for washing water.

(1) The washing vibrating screen feeder should be able to adjust the speed to overcome the fluctuation of the mud content in the feeding material. The material layer of the screen surface should be kept uniform, the action point of the flushing water should be effective, and the water pressure should be sufficient.
(2) The cylinder washing sieve should be equipped with a suitable feeder and a ring of resistance. The action point of the flushing water should be effective and the water pressure should be sufficient. The length of the non-porous section and the perforated section are determined based on the ore washability and the feed size characteristics. The size of the mesh depends on the particle size composition of the material, the suitability of the subsequent work equipment, the washing and screening effects.
(3) Before ore washing, it is advisable to pre-wet the ore and hand-selected mud, especially difficult to wash the ore, which can improve the washing effect.
(4) The washing equipment wears out quickly, and it is necessary to install lifting equipment that is convenient for repairing and replacing parts.
(5) The lifting capacity of the slurry pump should adapt to the fluctuation of the flow rate of the washing ore slurry, and the speed governing device should be adopted.
(6) The self-flow slope of all materials must be sufficient. The water content of the washing products transported by the belt conveyor must be reduced. The lifting angle should generally be less than 12°.
(7) The washing process has a large amount of water, and there are many opportunities for running water in the water pressurization operation. The floor and platform should have suitable slope and perfect sewage system to ensure a good working environment.
