TECHNICAL FIELD Ta

The present application generally relates toa field of materials science and - mineral engineering, and more particularly, to a system, and a method for complete - material sizing solution. -

BACKGROUND

Present Solid classification system:

Presently for dry or wet classification equipment, such as dry and wet screens are used to classify coarser particles while for finer applications screw/bucket wheel classifiers are employed. In case of dry classification, the number of products that can be produced from a single unit is highly restricted and it also generates dust pollution. Other than this, dry systems are highly inefficient for classifying materials with moisture. both dry and wet screens cannot effectively remove contaminants sticking to the surface of the material while remaining limited to the number of products that can produced by a single unit. In case of screw/bucket wheel classifiers, it cannot be used for classifying coarser particles and are generally used for removing clay from finer particles. This equipment also carmot remove surface contaminants or produce multiple product sizes in single unit.

Disadvantage of the present technology:

Presently classification employs the above mentioned equipment in : isolation and is limited by sizes of material it can process and number of products it can deliver to the user in a single unit. For example a dry/wet screen or screw classifiers/bucket wheel cuts material at different sizes but the product still contains : other foreign objects like silica, clay and alumina and the rejects too contains a large :

amount of usable material. This material then must be processed by using other systems - to recover the usable materials from rejects. The final product from this system still = contains foreign objects sticking to the surface of the material and is not properly - cleaned due to absence of any scrubbing and rinsing action. An additional scrubbing ) system is then required to remove the deleterious objects from the material to maximize B its full potential. Also in such system there is no process to recover very fine material Lu and for this the user must install the separate fines recovery systems in order to - reprocess the rejects or face a huge wastage of an important natural resource. = ft

In view of the above mentioned drawbacks, there exists a need for an efficient integrated system that provides a facility of scrubbing, hydro-cycloning, rinsing, sizing, dewatering and conveying into a single to classify substance that may include materials and/or minerals.
