Durable Mineral Spiral Classifier with Reliable Performance

    Spiral classifier is one of the beneficiation equipment. Spiral classifier is a kind of equipment for mechanical classification based on the principle that the specific gravity of solid particles is different, so the speed of precipitation in liquid is different. The material powder milled in the mill can be graded for filtering, and then the coarse material is screwed into the mill inlet with a spiral blade, and the filtered fine material is discharged from the overflow pipe. The spiral classifier is referred to as a classifier. There are four types of classifiers: high weir single and double spiral, submerged single and double spiral. The classifier is mainly composed of a transmission device, a spiral body, a trough body, a lifting mechanism, a lower support (bearing bush) and an exhaust valve. Spiral classifiers are widely used in the ore dressing plant to match the ball mill with closed-loop circulation and split-flow ore sand, or in gravity ore dressing plants to classify ore sand and fine mud, as well as to classify the size of the pulp in the metal beneficiation process and to wash the ore.

    Spiral classifiers are widely used in ore dressing plants to be equipped with ball mills for closed-loop circulation to split ores, or for gravity. In the ore dressing plant, the ore and fine mud are classified, and the size classification of the pulp is carried out in the metal beneficiation process, and the operations such as desliming and dewatering in the washing operation are performed. The machine has the characteristics of simple structure, reliable operation and convenient operation.

    The spiral classifier is mainly composed of a transmission device, a spiral body, a trough body, a lifting mechanism, a lower support (bearing bush) and an exhaust valve.

     The water tank of this machine is installed at an inclined angle. The inclination angle is determined according to the equipment configuration in the process. The transmission device drives the screw to rotate in the tank. The finely ground slurry enters the tank from the side feed inlet and forms a groove at the lower end of the tank. The surface area and volume of the slurry subsidence area are determined by the inclination of the sink and the height of the overflow weir. The low-speed rotating spiral can play a certain stirring effect. After the slurry is stirred, the light and fine particles are suspended on the top to form an overflow, which overflows from the overflow weir at the end of the water tank and flows into the next beneficiation process; the coarse particles sink to the bottom of the tank to form Sand is transported by spiral to the ore discharge outlet.
