OPERATING PRINCIPLES:

DOVE Concentrating Tables (Shaker Tables) comprise of a table, or Deck, with a ultra smooth rubber covering the entire surface of the Deck, on to which is incorporated (Cemented) a series of rubber Riffles. At one end of the deck is Head-Motion, which is designed to impart a reciprocating movement to the table’s deck in a horizontal plane. The Head Motion eccentric produces the motion, which is designed to move the material on the surface of the Deck to move forward across the Table.

Parallel to the movement and shaking action caused by the head motion, a very thin layer of water is introduced across the deck. The same movement cause the shaking action, imparts a jigging action across the deck, which results in size classification, separation and stratification of solid particles based on their specific gravity. Separation will be also influenced by the length of the Head Motion stroke and by the reciprocating speed.

The flow of cross water causes shearing of stratified material and forces it to cascade over the rifle surface of the table’s deck. Lower specific gravity material remains close to the water surface and rides over the riffles towards discharge end of the table; higher specific gravity material is being hold back by the riffles, which is closest to the table’s surface, and moving along the table’s deck to the concentrate discharge.

Absolute smoothness of the Deck action is highly critical for maintaining high recovery and high capacity. Deck is supported on an extra rigid, heavy, all steel sub frame, which is mounted on heavy steel channel main frame and configured with heavy duty Rockers. This configuration design of rigid and strong under fabrication insures against the most imperceptible deck flutter. The Deck weight is equally distributed over a series of splash proof slide bearings mounted on the rigid sub frame. DOVE Under Carriage design eliminates Deck Warping, which is common in many decks.

DOVE Concentrating Tables (Shaker tables) range is comprised of three different types of Decks, consist of Wooden Deck type, Fiber Glass Deck type and Aluminum Deck type. The three types of the shaker tables mechanically designed and operate on the same principal. The difference is the application, the type of ore to be concentrated, size range, and the performance, as well as the durability of the Table.

The Wooden deck type is the most common type, widely used across industry, in various applications, supplied in rectangular or diagonal shape, with ultra-smooth rubber cover and riffle surface and are operating in horizontal plane, where material with higher specific gravity is separated from material with lower specific gravity. Wooden Deck type is highly efficient and carries proven record in efficient concentration and recovery of coarse and fine material, with maximum particle intake of 7 mm, used for both primary and secondary concentration of coarse, fine and slime. Wooden Deck is lighter than Fiberglass and Aluminum deck tables.

The Fiberglass Deck type is fairly new in the industry, it has been popular due to its cost, which is slightly lower than wooden deck table, it is recommended for maximum particle intake of 2 mm. it is mainly applied as primary step of concentration. However, for fine particle and slime concentration, as secondary step, should use wooden Deck table. Fiberglass table is heavier than Wooden Deck tables and have shorter life span, and as the result of shock created by the speed and pulse of the Head motion, the Fiberglass deck tend to crack on the surface and also in some instances the deck experience warping, which can effect the recovery.

The Aluminum Deck type is very heavy and lower capacity than Wooden Deck Type. It is also mainly recommended for primary concentration and initial cleanup. This type of Deck is not popular and tends to be expensive.
