Hydrosizer/TBS

The Hydrosizer/TBS is used by a wide range of Mineral Processors to beneficiate and classify minerals generally < 5 mm in size. Minerals such as:

• Silica sand is treated using the TBS/Hydrosizer to produce high-grade sand for concrete products, for glass making or foundry use. The process can also incorporate the removal of contaminants such as Lignite and fish from the sand.
• It is also used in Coal Preparation, treating both run-of-mine coals and the recovery of coal from waste tips.
• Ore Dressing.
• Removal of silica from iron ore
• Separation of minerals from sand such as Ilmenite, Rutile & Zircon

The Hydrosizer/TBS is a hindered settling classifier which, utilises an upward current of water to create a bed of material within its cell, the material held in the cell is in a state of 'teeter' and it comprises a narrow size band. When particles that are larger (or heavier) enter the cell they penetrate the teetering material and those that are finer or lighter are displaced to the overflow. By employing an accurate sensing device with a constant flow of upward current water, well defined separation is achieved.

Each machine is manufactured to exacting standards with abrasion resistant linings where necessary and utilises an Electro/Hydraulic control system, which can if required operate in conjunction with PLC & computer controlled systems.

There is a range of single cut production machines from the TBS 900 to TBS 3650

Other machines using the same principles include the Multi Spigot Hydrosizer often used as a pre-concentrator prior to shaking tables and the Hydrolig developed to remove deleterious matter such as lignite and fish from sand & gravel up to 40 mm in size.

The removal of contaminants from aggregates used in the production of concrete is likely to become standard practice for operators processing riverbed or marine dredged aggregates.

Operators treating deposits with high levels of silt would also benefit from using the Hydrosizer/ TBS.
