1. General Introduction

Double-shaft crusher is a kind of crushing equipment widely used in the industrial field. Its main function is to grind, impact and crush the raw materials continuously, and finally turn them into the required finished products. Due to its excellent crushing effect and crushing efficiency, double-shaft crusher is widely used in mining, stone processing, building materials, road construction, cement production and other fields.

2. Working Principle

Double-shaft crusher is mainly composed of feed port, blade of appropriate size, fragmentation chamber, reverse comb teeth, etc. When the raw materials pass through the feed port and enter the fragmentation chamber, they begin to be cut, impacted and crushed by the double-shaft rotation driven by two gears with different speeds. After repeated operations, the material is cut into small pieces, and the final block material is discharged through the screen outlet. The material under the screen returns to the crushing chamber for grinding again, and finally becomes the required finished product.

3. Advantages Analysis

Compared with the traditional single-shaft crusher, the double-shaft crusher has the following advantages:

(1. High efficiency: The axes of the double-shaft crusher are parallel, which effectively reduces the friction resistance. Therefore, compared with the single-shaft crusher, its crushing effect is better.

(2. Low energy consumption: Since the double-shaft crusher adopts a double-shaft rotating design, the energy consumption is lower. In mass production, it can significantly reduce production costs.

(3. Strong self-cleaning ability: The double-shaft crusher is equipped with reverse comb teeth. When foreign matter in the raw material enters the crushing chamber, it will not jam the blade, but will use its own cleaning ability to expel the foreign matter. out.

IV. Application fields

Double-shaft crushers are widely used in the following fields, including:

(1. Metallurgical industry: crushing of metals such as aluminum, iron, and steel.

(2. Building materials industry: crushing of cement, glass, crystal and other products.

(3. Mining industry: crushing of minerals such as ore and rock.

(4. Chemical industry: crushing of various chemical raw materials.

V. Conclusion

Double-shaft crusher, as a high-efficiency, low-energy-efficiency, and strong self-cleaning crushing equipment, has become an indispensable part of the industrial field. In the future engineering and production fields, its application and development prospects will become increasingly extensive.
