1. Spiral classifier is one of the equipment of mineral processing. 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. It can filter the grinding powder in the mill, and then screw the coarse material into the feed port of the mill by using the spiral blade, and discharge the filtered fine material from the overflow pipe. Spiral classifier is called classifier for short. There are mainly four kinds of graders: high weir single screw and double screw, submerged single screw and double screw. The classifier is mainly composed of transmission device, spiral body, tank body, lifting mechanism, lower support (bearing bush) and discharge valve. Spiral classifier is widely used in concentrators and ball mills to form a closed-circuit cycle and separate ore sand, or in gravity Concentrators to classify ore sand and fine mud, and in metal beneficiation process to classify the size of pulp, as well as desliming and dewatering in ore washing operation< The spiral classifier mainly includes high weir type single screw and double screw, low weir type single screw and double screw, submerged type single screw and double screw. The low weir type is rarely used, mainly high weir type, submerged type and XL spiral classifier< The spiral classifier is widely used in ore dressing plants to form a closed-circuit cycle with ball mill to separate ore sand, or in gravity dressing plants to classify ore sand and fine mud, and in metal dressing processes to classify ore pulp particle size, as well as desliming and dewatering in ore washing operations. The machine has the characteristics of simple structure, reliable operation and convenient operation the base of the machine is made of channel steel, and the machine body is welded with steel plate. The head of screw shaft and shaft head are made of pig iron sleeve, which is wear-resistant and rable. The lifting device can be divided into electric and manual.

Hengcheng mineral processing gives you a detailed explanation of the working principle and operation theory of the spiral classifier:

1. The working principle of the spiral classifier is to feed the pulp into the U-shaped groove from the middle feed port on the side of the groove

2. The U-shaped groove makes the pulp flip back and forth, which will make the lighter particles fall at the bottom, while the heavier ones are located on the upper side, so as to separate the materials of different sizes and weights
The spiral classifier of mineral processing equipment is different from some other equipment for transporting grit, which can be divided into spiral classifier, rake classifier and floating trough classifier. The outstanding one here should belong to the spiral classifier. The main reason is that it has the characteristics of simple structure, convenient operation, large skew point of view and so on. It is easy to connect with the grinding machine for gravity flow, so it is widely used
Second, the operation theory of spiral classifier of mineral processing equipment

other classifiers are distinguished by the size and weight of solid materials, so the settling velocity in liquid is different. Fine ore particles float in water and overflow, while coarse ore particles sink at the bottom of the tank. Spiral classifier is a kind of classification equipment for mechanical classification. Because it can be connected with the mill, it can grade and filter the raw materials from the mill, and then grade the coarse and fine materials. The base of this type of machine is made of steel groove, and the body is made of steel plate by welding, so the machine is very firm. The various parts of the spiral shaft use pig iron sleeve, so it is very wear-resistant. And its performance compared with other classifiers are also greatly improved, so it is widely used in proction

5. Hello: you said that the anti sand water is actually backwater. I wonder if your concentrator has a flotation system? If there is a flotation system, the first thing to consider is whether the nature of flotation reagent will cause backwater viscosity. If it is viscous, it will affect the pulp viscosity and flow rate inside the mill (pulp will change when it reaches the highest point with the operation of the ball mill) and the discharge speed, and even lead to swelling. If the pulp inside the ball mill cannot be removed in time for a long time, the internal concentration will increase, The fineness will definitely decrease
in addition, attention should be paid to the acidity and alkalinity of backwater
generally speaking, backwater has little effect on fineness, but has some effect on other flotation indexes

Spiral classifier mainly includes high weir single screw and double screw, low weir single screw and double screw, submerged single screw and double screw. Low weir is rarely used, mainly high weir, submerged and XL spiral classifier
