The classifier mainly has four kinds of high weir type single spiral and double spiral, submerged single spiral and double spiral classifier. The classifier is widely used in the concentrator with the ball mill into a closed cycle separation of ore sand, or used in the gravity concentrator to grade ore sand and fine mud, metal beneficiation process for pulp particle size classification, as well as washing operations in the desilting, dehydration and other operations. The classifier has the characteristics of simple structure, reliable operation and convenient operation.
Working principle
Working principle of the classifier: The classifier is based on the principle that the size of solid particles is different, the specific gravity is different, and therefore the settling speed in the liquid is different, the fine ore particles float in the water into overflow, and the coarse ore particles sink at the bottom of the tank. A classification device for mechanical classification by pushing the screw to the upper part of the discharge, which can add the grade of powder ground in the mill to the filter, and then screw the coarse material into the feed port of the mill by using the spiral plate, and discharge the filtered fine material from the overflow pipe. The machine base is made of channel steel, and the body is welded with steel plate. The inlet head and shaft head of the spiral shaft are made of cast iron sleeves, which are wear-resistant and durable, and the lifting device is divided into two kinds: electric and manual.
Other instructions
Advanced technology, simple process
The equipment has advanced technology and simple process, which is especially suitable for large and medium sand production lines of dry process.
Reliable, convenient and flexible operation
The inlet head 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% and 15%.
Low maintenance rate, strong wear resistance
Using tile lining, low maintenance rate; The base is made of channel steel, and the body is welded with steel plate, with good quality and high wear resistance.
