Classification Plays a Key Role in Mining Process

The classification is an important preparation process for the mineral processing. The situation and result of the classification will directly affect the subsequent operation indicators of the concentrator. In the beneficiation process, there are a lots of classification equipments, and the mining spirals is one of them.
Henan Hongxing Mining Machinery Co., Ltd. is a well known classifier manufacturer and supplier in China. Here Hongxing experts will introduce the mining spirals from application, structure and feature three aspects.
The mining spirals is not only widely applied to the closed circuits, which is equipped with Ball mills to split flow the mineral sand in concentrator, but also widely used for the classification of mineral sand, fine silt in the concentrator, or for the size grading of ore pulp in the metal ore dressing process, or for the desliming and dehydration in the washing operation. This mining spiral has the features of simple structure, reliable work, easy to operate and so on.
The mining spiral is mainly composed of the transmission device, spiral body, cell body, elevator mechanism, lower bearing (bearing bush) and ore exhausting valve.
Grader transmission of spirochetes, tank, lifting mechanism, lower seat (bush) and mine Drainers. According to the form, the mining spirals can be divided into the high weir single spiral classifier, the high weir double spiral classifier, the sunken single spiral classifier, and the sunken double spiral classifier.
The mining spiral is compact in structure, easy to use, and can form the closed loop gravity with the ore mill, so it is widely used in the concentrator. However, the mining spiral covers a large area and has a lower classifying efficiency, both of which limit its application. In recent years, in the first step of grinding and classifying assignment, it began to use the swirler to replace the mining spirals and the closed circuit of the grinding mill. Therefore, how to improve the classifying efficiency of the mining spirals and show its inherent advantages becomes an important research topic.
