Gravity Table

Floating shaker table in pioneers used primarily for sorting coarse grain size of the tungsten-containing rock and placer tin or nonferrous metal sulfide ores containing sulphides of tin concentrates or coarse scheelite - wolframite - cassiterite mixed concentrate ore particle size is usually in the range of 0.2 ~ 3mm, individual cases can reach 6mm.





These sands crude density difference or need to concentrate minerals with similar specific gravity, then the normal gravity separation method can not achieve effective separation; flotation separation by single flotation concentration, because the particle size is too large, and unable to obtain satisfactory technical indicators by only froth flotation. At this time, we introduce our TF-4500*1850 floating shaking table in pion eers with complete wooden riffle deck which can be coated with rubber.

Shaking tables are designed to wet gravity-based separation of minerals and other granular materials. There are many applications where the concentrating table is of particular value and cannot be equaled for economical and efficient performance.

Application

Shaking tables are used to treat a great variety of materials, ranging from heavy material, ranging from heavy sulphides (specific gravity 7.5) to coal (specific gravity 1.3), at some cases below 50um.


Export container load

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.

The most Economic and Practical Ultra-fine Powder Processing Equipment, the Energy-saving and Reduce Consumption Equipment fro ultra fine Powder Processing

HCH ultra-fine grinding mill is especially suitable for ultra fine grinding. With yearsâ?? accumulation of experience in R&D, the HCH Ultra-fine Grinding Mill is a new ultra fine pulverizing equipment designed by Hongcheng. This mill is widely used to grind any non-metal minerals with Moh's hardness below 7 and moisture below 6%, such as talc, calcite, calciumcarbonate, dolomite, bentonite, kaolin, graphite, carbon black, etc. HCH Ultra-fine Grinding Mill features in space-saving, completeness, wide usage, easy operation, smooth performance, high performance-cost ratio and high efficiency. HCH1395 Grinding Mill is the biggest ultra fine circle-roll grinding mill in China.

Working Principle
Technological process: The pre-grinding raw ore material will be crushed into particlesï¼?10mm and transport to the feeding hopper by the elevator, then feed into the grinding chamber by the feeder. The grinding rollers equip on the rotary table rotates around the centre shaft. There is flexible gap between the roller and ring. The rollers rotate outward by the centrifugal function to compress the fixed ring. The rollers also self- rotates around the roller pin. When material passed through the gap between the ring and roller, the material will be smashed by the rotating rollers. Four layers of rollers. Material will be grinded 1st time when passing the 1st layer of roller and ring. Then be grinded second, third and fourth time when loop through each layer rollers. Thus the materials were grinded sufficient and obtain much fine powder. The powder fallen down onto the bottom table by gravity will goes up to the classifier for separation by the airflow from blower. The qualified fineness passing from the classifier will be collected by the pulse bag collector as final product, while unqualified fallen down for regrinding till passing through. The powder goes with air flow into the pulse bag filter and collects by the discharging valve. The wind path is in circulation and the airflow is in negative pressure. There will be no dust escape, so the equipment can ensure a no dust operation in workshop.

Application Range
HCH Ultra-fine Grinding Mill is widely used to grind any non-metallic minerals with Mohs hardness below 7 and moisture below 6%, such as talc, calcite, calcium carbonate, dolomite, bentonite, kaolin, graphite, carbon black etc.. This kind of mill is especially suitable for ultra fine grinding. The fineness can be adjusted from 0.045mm(325 mesh) to 0.005mm(2500 mesh), whose range is much wider than that of traditional Raymond Mill.
