It is one of the main gravitational segregation equipment in the enrichment plant, widely applies in the classification tungsten, the tin, the tantalum niobium and other rare metals and the noble metal ore. Also available in classification iron, manganese ore and coal. When ore and so on processing tungsten, tin, the table effective recycling granularity scope is 2-0.22 millimeters. The table dressing process carries on the complex inclined bed surface , and the ore grains are sent in from the bed surface for the ore trough, simultaneously it supplies crosswise wash for the water trough, thus the ore grains laminate surface and according to the proportion and granularity, and make the longitudinal motion and transversal motion along the bed surface, in function of the gravity, the crosswise running water momentum, and the inertia and friction force from the reciprocation symmetry movement of bed surface. Therefore, the proportion and the granularity different ore grain assumes gradually along respective heading by a on the one hand to b on the other hand fan-shaped flows off, separately discharges from the ore concentrate end and the debris side different area, finally is divided into the ore concentrate, the middling and the debris.
1.Spiral chute is to make seperations of useful minerals from gangues by use of the different particles to gravity hydraulic pressure and friction in the multi-force field through dynamic contrifugal flowing membrane of slurry produced on the inclined surface of spiral based on the differences of useful mineral and gangue in specific gravity,particle size and shape. 2. Spiral chute (glass fiber reinforced plastics spiral chute) is applicable to metal and non-metal ores with adequate density difference, like iron, chromite, pyrite, tin ore, tungsten, tantalum, niobium, gold ore, colliery, monazite, rutile and Zirconium.
1. The gold centrifugal concentrator is a relatively new type of gravity concentration equipment.The machines utilizes the principles of centrifugal to enhance the gravitational force experienced by feed particles to effect seperation based on particle density. 2.The key components of the unit are a cone shaped concentrate bowl, rotated at high speed by an electric motor and a pressurize water jacket encompassing the bowl. 3.Centrifugal concentrator can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation and recover gold from the old tailings. 4.Application shows that the recovery can be as high as 99precentage and the concentrating ratio is up to 1000times.In recovering the natural gold in lode ore with 65percentage of the ore having a milling size -0.074mm, the recovery for the natural gold is up to 98percentage.For the natural gold of 0.004mm in particla size, the gold recovery is 97percentage.The equipment is patented in china.
