Polyurethane impeller cover plate for flotation machine. The impeller cover plate is the rotor stator of the flotation machine, also known as the water wheel cover plate. It is used for mixing and abrasion. The rubber impeller cover plate has high wear resistance and is vulcanized with high wear resistance tire top rubber as the main material. The general life span is about 8 months. Polyurethane material greatly improves the wear resistance time. In mine practice, it can reach 3 years. The number of maintenance and repairs saves money and labor. It is an ideal replacement product.
The function of the impeller cover on the machine is:
1. When the pulp is thrown out by the impeller, a negative pressure suction is formed under the cover plate;
2. Adjust the amount of pulp entering the impeller;
3. It can prevent the ore from pressing the impeller when it is stopped and difficult to start;
4. Play some role in steady flow.
When the flotation machine is working, the mine tube feeds the pulp to the center of the cover plate, and the centrifugal force generated by the rotation of the impeller throws the pulp out, and at the same time, a negative pressure is formed between the impeller and the cover plate, so it is automatically sucked into the outside through the intake pipe. air. The strong stirring effect of the impeller makes the pulp and air fully mix, and divides the airflow into many tiny bubbles. In addition, some bubbles will be precipitated from the slurry behind the impeller blade.
Features of the impeller cover on the flotation machine:
1: Large suction volume, low power consumption
2: Each tank has both suction, slurry suction and flotation to form a flotation circuit, without any auxiliary equipment, horizontal configuration, easy to change the process.
3: The slurry in the tank is recycled, which is beneficial to the suspended recovery of coarse minerals.
4: It is equipped with manual control, automatic control and electric control device for the pulp surface, which is convenient to adjust.
5: The impeller is composed of a closed double truncated cone, which can produce strong slurry circulation.
Chaishang Trading’s flotation machine stator rotor is a high-efficiency flotation machine stator and rotor designed by CAD and UGS, and molded with high wear-resistant rubber, which has a wear-resistant effect more than 3 times that of ordinary stator rotors.
In addition, the stator and rotor of the flotation machine of Chaishang Trading Co., Ltd. can be manufactured according to different requirements by using rubber formulas such as wear resistance, corrosion resistance and oil resistance according to the working conditions and parameters of the slurry provided by the concentrator.
