The impeller and cover plate of the flotation machine are the main components of the flotation machine equipment. In the working process of the flotation machine, its impeller and cover plate have the function of self-priming slurry similar to the slurry pump. It is precisely because the impeller and cover plate of the flotation machine have the function of self-priming pulp (or self-aspiration), its impeller and cover plate are worn out and have a short life span and need to be replaced frequently. Therefore, how to choose a material with good wear resistance for the impeller and cover of the flotation machine is of great significance.
The impeller cover of the flotation machine is made of cast iron, alloy materials, polyurethane, wear-resistant rubber and other materials. Among many wear-resistant materials, wear-resistant rubber has been strongly sought after by customers for its superior wear resistance! Practice! And research shows that the use of wear-resistant rubber materials as impeller and cover material has the following advantages:
1. Long service life.
Using conventional cast iron and other materials, corrosion resistance and impact resistance cannot be achieved at the same time. For example, although cast iron is resistant to corrosion and abrasion, it is brittle and has poor ability to withstand the impact of solid particles. During the rotation of the impeller, solid particles have a strong impact on the impeller and cover plate, and the service life of the impeller cover plate made of cast iron is not long. . The impeller and cover plate made of wear-resistant rubber have the functions of corrosion resistance and impact corrosion resistance, which greatly extend the service life of fragile flotation machine components.
2. The amount of maintenance and replacement of impeller and cover plate is small.
In order to ensure the normal operation of the flotation machine, the impeller and cover plate need to be replaced and repaired in time. The impeller and cover plate made of cast iron and other materials have a short service life and a large amount of repair and replacement. However, the impeller and cover plate made of wear-resistant rubber have a long service life, so the amount of maintenance and replacement of the impeller and cover plate is small.
3. It has little impact on production indicators and production processes.
The impeller and cover plate made of cast iron and other materials will be worn for a period of time, and the gap between the impeller and cover plate will become larger, resulting in insufficient stirring strength and circulation degree of the flotation machine, which will affect the flotation index , And because the impeller cover of cast iron and other materials needs to be replaced frequently, it will delay the flotation process. The impeller and cover plate made of wear-resistant rubber have good wear resistance and long service life, so they have little impact on production indicators and production processes.
4. The input cost of spare parts such as impeller cover plate is low.
The impeller and cover plate made of cast iron and other materials have a short service life, so a large number of spare parts are required, and the scrap rate of components is also high, so the production cost is high. The impeller and cover plate made of wear-resistant rubber material have a long service life, so the input cost of spare parts such as the impeller cover plate is low, which is beneficial to reduce the cost of flotation.
Polyurethane flotation machine rotor stator has both the high strength of plastic and the high elasticity of rubber. It is a new wear-resistant flotation machine rotor stator with excellent comprehensive performance.
Product features: high wear resistance, high wear resistance, corrosion resistance, longer life, reducing the number of replacements of cast iron and rubber impeller covers.
is widely used in flotation equipment in lead-zinc ore, copper ore, gold ore, titanium ore, ore and other non-ferrous metal mines.
