There are four 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-circuit cycle with ball mills to separate ore sand, or to classify ore sand and fine mud in gravity ore dressing plants, to grade ore pulp in metal ore dressing processes, and to remove mud and water in ore washing operations.

Product Introduction：

Scope of application of classifier: There are four types of classifiers: high weir single spiral and double spiral, submerged single spiral and double spiral. The 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 ore pulp in metal ore dressing processes, and to desludging and dehydrating in ore washing operations. The classifier has the characteristics of simple structure, reliable operation and convenient operation. Classifier structure: The classifier is mainly composed of a transmission device, a spiral body, a trough body, a lifting mechanism, a lower support (bearing) and a discharge valve.

Product Advantages：

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 are made of cast iron sleeves, which are reliable in operation; the quality of stone powder is easy to control, and the content of 0.00--0.75mm stone powder is adjustable between 2%-15%.

Low maintenance rate and strong wear resistance

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

How it works：

The classifier is a grading device that uses the principle that solid particles of different sizes and specific gravities have different settling speeds in liquids. Fine ore particles float in the water and overflow, while coarse ore particles sink to the bottom of the tank. The material is pushed to the upper part by a spiral and discharged for mechanical grading. It can filter the powder ground in the mill, and then use the spiral vanes to screw 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 are made of cast iron sleeves, which are wear-resistant and durable. The lifting device is divided into electric and manual types.
