working principle
Working principle of spiral classifier: The classifier relies on the principle that solid particles have different sizes and specific gravity, and therefore have different settling speeds in the liquid. Fine ore particles float in the water and overflow, while coarse ore particles sink to the bottom of the tank. It is a kind of classification equipment that is pushed to the top by a spiral and discharged to perform mechanical classification. It can add the powder grade of the material ground in the mill to the filter, and then use the spiral blade to screw the coarse material into the feed port of the mill. The filtered fine materials are discharged 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 head and shaft head of the spiral shaft are made of pig iron sleeves, which are wear-resistant and durable. The lifting device is divided into electric and manual.
Performance characteristics
1. This equipment has advanced technology and simple process, and is especially suitable for use in large and medium-sized dry sand making production lines.
2. The water inlet head and shaft head of the spiral shaft are made of pig iron sleeves, which are reliable in operation; the stone powder quality is easy to control, and the 0.00--0.75mm stone powder content is adjustable bet ween 2% and 15%.
3. It is lined with tiles and 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.
