There are four main types of classifiers: high weir single spiral and double spiral, submerged single spiral and double spiral. This classifier is widely used in ore dressing plants to form a closed-loop cycle with ball mills to separate ore sand, or used in gravity ore dressing plants to classify ore sand and fine mud, to grade slurry in metal ore dressing processes, and to desludging and dehydrating in ore washing operations. This classifier has the characteristics of simple structure, reliable operation, and convenient operation.

Working principle

Working principle of classifier: The classifier uses the principle that the solid particles have different sizes and specific gravities, and therefore have different settling speeds in the liquid. Fine ore particles float in the water and overflow, and coarse ore particles sink to the bottom of the tank. It is a grading equipment that is pushed to the upper part by the spiral to perform mechanical grading. It can filter the powder grade ground in the mill, and then use the spiral blades to rotate the coarse material into the mill feed port, and discharge the filtered fine material from the overflow pipe. The base of the machine is made of channel steel, and the body is welded with steel plates. The water inlet and shaft head of the spiral shaft adopt cast iron sleeves, which are wear-resistant and durable. The lifting device is divided into electric and manual types.

Other descriptions

Advanced technology, simple process

The equipment has advanced technology and simple process, and is particularly suitable for large and medium-sized dry sand production lines.

Reliable, convenient and flexible operation

The water inlet and shaft head of the spiral shaft adopt cast iron sleeves, which are reliable to operate; the quality of stone powder is easy to control, and the content of 0.00--0.75mm stone powder can be adjusted between 2%-15%.

Low maintenance rate and strong wear resistance

The tile lining is adopted, with low maintenance rate; the base is made of channel steel, and the body is welded with steel plates, with good quality and high wear resistance.
