Spirals are gravity concentrators and separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. It has extremely good performance and effects in processing placer of beach, riverside, seashore and stream.
í¦Gandongí¦ Spirals are made of polyurethane lined fiber glass with wearable corundum inner surface.
Generally there are 5 turns in one start, single, twin, triple and quad starts available per column to suit capacity requirements.
Application
Rutile, ilmenite and zircon concentration
Iron ore, chromite and manganese beneficiation
Tin, tantalum and ore concentration
Gold, native copper and base metal recovery
Silica sands processing
Titano-magnetite concentration
Feature & Benefits
Reasonable structure and small occupation area
High recovery, high efficiency, and precise separation,
Light in weight, rust and corrosion resistant;
Simple installation and Minimal maintenance requirements
Low operating cost and long operating life
Reliable running with minimal operator attention
Strong adaptability to fluctuation of feeding amount, density, size and grade.
Jigging machine belongs to gravity-based equipments, which can separate mineral based on differing of specific gravity. Gandong saw-tooth wave jig is mainly consist of three parts: main frame, driving set and jigging chamber.
Application
Jigging machine is widely used in gravity concentration of tin, tungsten, placer gold, hematite ore, manganese, titanium, antimony, lead, tantalum, niobium and other minerals.
Features
The pulsing curve of the traditional jig is sinusoidal waveform, the up and down speed of water flow and acting time produced by the movement of membrane are almost same, so it is unfavorable to loose of jig bed and layering of minerals based on special gravity, and thus affect separation ability and recovery rate. Saw-tooth wave is energy economy gravity equipment that is developed and improved from traditional jig on the basis theory of jig bed layering. Its jigging pulsating curve is similar to saw-tooth wave, which makes the up speed of water flow quicker than down speed of water flow, so it can improve looseness of jig bed and reduce suction action, which can lead to fully settlement of heavy particles in slurry, it highly improves separation ability and recovery rate. Stroke and frequency of stroke are adjustable.
Application of shaking table
Concentrating 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. They are effective in processing precious and base metal, rare metal and non-metallic minerals.
Construction
Head Motion: The head motion is of rugged construction and requires minimum maintenance. Its internal mechanism is splash lubricated from an integral oil sump.
Decks: The decks are built of 16 mm zircon-reinforced fiberglass with fabricated steel frames at the bottom and are easy to clean, requiring little maintenance. The specific gravity of fiberglass made into decks is one third of that of steel, while its strength reaches as high as 70% that of steel. This fiberglass desks also has the characteristic of water-resistance and corrosion-resistance and can hold the shape unchangeable at f+50f¦.
Feed and Water Box: A wooden feed distributing box with hopper and a long water box are attached to the iron of the deck, giving a very even distribution of feed and water.
Base: A choice of ordinary type, groove steel support or big channel steel support is available.
Technical Specification
The Gandong Shaking Tables have three distinct deck designs available.
The course ore deck is designed for recovering particles sized from 0.5 mm to 2 mm; the fine sand deck is designed for recovering fine particles in the range of 0.074 mm to 0.5 mm; the slime deck is designed for recovering super extremely fine particles in the range of 0.05 mm to 0.074 mm.
Concentrator is kind centrifugal concentration equipment. It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings.
Three models are available. Application shows that the recovery can be as high as 99%, especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of í¬0. 074mm, the recovery for the natural gold is expected up to 98%. For that natural gold of 0.004mm in particle size, the recovery is 97%. The cleaning up cycle is 1~4 hours, and the upgrade ratio is up to 1,000 times. The equipment is patented in China.
