XingBang crusher independent research and development_Ivylm522beneficiation magnetic beneficiation, the re-election beneficiation and flotation beneficiation.Mainly described here is of Henan prosperous Heavy mineral processing methods re-election, the following solution: [1] jig election Vertical alternating currents so that the material is loose, to stratified and selected according to the proportion of the process.The basic components of the jig jig rooms, rooms built screen.Water and a mixture of mineral particles into the jump from one end to the elimination room sieve, mineral particles in the vertical alternating the role of water movement, alternating occurrence of loose and tight, and finally according to their own specific gravity stratification.A small proportion of the products in the upper flow with the slurry discharged from the upper; lower than the major product in the lower part of the discharge.A wide range of jig beneficiation jig more than by the reciprocating motion of the diaphragm caused by the flow of alternating movement, the formation of the zigzag motion curves in favor of the hierarchicalPiston jig with compressed air so that water up and down movement.Main Baum and new screen under the air chamber type, in most cases re-selection in coal preparation, a few cases also used for mineral processing.The pulse waveform of the flow is an important factor affecting the process of jigging.Granularity of the material ball mill is stratified according to the proportion, it sometimes will be screening the ore into the narrow level were selected.Jig operating parameters for Rotary Kiln the flow of stroke, stroke, sieve under water recharge, the feeding and to feed concentration and the proportion of the stone of the bed, particle size and thickness.Jig unit area processing capability, device structure is simple, easy operation and maintenance.As beneficiation scale expansion, the jig trend of large-scale.Dressing up to 7.5m diameter circular jig jig room, an area of ​​42 square meters.Use in coal preparation piston jig jig room area reached 35 square meters. [2] shaker election Shaker (shaking table) from the bed surface and the transmission mechanism with a lateral tilt of the bed strips or grooves.The drive mechanism so that the bed surface, the longitudinal asymmetry of reciprocating motion.The mineral particles of the bed surface of the pulp lateral flow and bed inter vortex under the combined effects of mechanical vibration, loose from the analysis, stratified zoning.Upper ore particles the proportion of small particle size, the lower mineral particles than significant, the particle size is small, the upper slurry flow rate faster, so the mineral particles of lateral movement was faster; lower slurry flow rate, the mineral particles due to bed friction by mechanical handling power of longitudinal movement speed; mineral particles of different size and proportion of the bed surface trajectories and separation. The motion characteristics of the transmission mechanism, the bed and bed shape, size and layout.The main operating parameters of the bed of stroke, stroke, lateral inclination, rinse water, to the amount of ore to the ore concentration.Typically, fine-grained with a small stroke to the mine, the high stroke and low bed bar; large stroke and low stroke and high bed.Shaker sorting efficiency is high, especially enrichment is high, a variety of products; but a small amount of equipment per unit area processing.To save area since the 1950s, a variety of multi-storey shaker, which suspended multi-shaker than the located type. [3] chute election Chute (spiral chute) with the material selected other process in the tilt of the flow of the slot flow.Mineral particles, gravity, friction, water flow, pressure, shear and block bar resistance (groove surface of the block time) under the combined effects of loose, layered to achieve separation by specific block machine gravity. According to the granularity of the processed material is divided into: ① coarse chute (feed size is usually 2 ~ 3mm, up to 100mm and above), fixed and belt for sorting gold, sand tin and tungsten ore, etc.; ② ore chute (feed size 2 ~ 0.074mm). Chute type more commonly used are the following.
