This machine is a device for mechanical classification by the principle that the specific gravity of the solid particles is different and the speed of precipitation in the liquid is different. The machine is combined with a ball mill to form a closed loop, which is used as a pre-washing grading and inspection pole for the mill, as well as for de-sludge dewatering of the particles used in the washing.
The classifier mainly has four types of sorghum single helix and double helix, sunken single helix and double helix.
Spiral classifier scope:
The classifier is widely used in the concentrating plant to form a closed loop cycle with the ball mill to split the ore, or to be used in the gravity ore dressing plant to classify the ore and fine mud, and to classify the slurry in the metal beneficiation process, and to wash the ore. Desliming, dehydration and other operations. The machine has the characteristics of simple structure, reliable operation and convenient operation. The classifier is based on the principle that the solid particle size is different, the specific gravity is different, and the sedimentation velocity in the liquid is different. The fine ore particles float in the water to overflow and the coarse ore particles sink to the bottom of the tank. A grading device for mechanical grading by pushing the upper part of the screw, which can filter the powdered powder in the mill to filter, and then screw the coarse material into the grinding machine feed port by using a spiral rotary piece, and filter The fine material discharged is discharged from the overflow pipe. The base of the machine is made of channel steel, and the body is welded by steel plate. The screw shaft has a water inlet head, a shaft head and a pig iron sleeve. It is wear-resistant and durable. The lifting device is divided into electric and manual.
The working principle of the spiral classifier:
The spiral classifier is based on the principle that the solid particle size is different, the specific gravity is different, and the sedimentation velocity in the liquid is different. The fine ore particles float in the water to overflow and the coarse ore particles sink to the bottom of the groove. A grading device for mechanical grading by pushing the upper part of the screw, which can filter the powdered powder in the mill to filter, and then screw the coarse material into the grinding machine feed port by using a spiral rotary piece, and filter The fine material discharged is discharged from the overflow pipe. The base of the machine is made of channel steel, and the body is welded by steel plate. The screw shaft has a water inlet head, a shaft head and a pig iron sleeve. It is wear-resistant and durable. The lifting device is divided into electric and manual.
Spiral classifier structure:
The classifier is mainly composed of a transmission device, a spiral body, a trough body, a lifting mechanism, a lower bearing (bearing bush) and a discharge valve.
