Description

Technical Field

[0001] This utility model belongs to the field of powder making machine technology, specifically relating to a high-efficiency powder making machine. Background Technology

[0002] Material crushing is classified into layered crushing, impact crushing, and grinding crushing. Vertical shaft impact mills are a type of impact mill, which uses a high-speed rotating motor to drive the rotor of the vertical shaft impact mill. Material entering the crushing chamber impacts against the impact liners surrounding the cylinder. The material is finely crushed through high-speed impacts between the material and the working surfaces of the impact liners, as well as through collisions between materials of different sizes within the chamber and between the material and the impact plates on the rotor. This type of mill produces materials with low powder content and uses a high-power motor. Summary of the Invention

[0003] Therefore, this utility model designs a high-efficiency grinding and pulverizing machine that can save a lot of energy and reduce the cost of fine crushing of materials.

[0004] The objective of this utility model is achieved through the following means:

[0005] A high-efficiency grinding mill includes a grinding mill rotor, a grinding roller support frame installed on the grinding mill rotor, grinding rollers installed on the grinding roller support frame, the grinding rollers corresponding to the grinding mill grinding ring, and a grinding roller adjustment device installed on the grinding roller support frame. The grinding roller adjustment device is a grinding roller adjustment spring, and the grinding rollers are installed at the ends of the grinding roller adjustment springs.

[0006] The aforementioned high-efficiency grinding mill has a grinding roller adjustment spring outer sleeve equipped with a grinding roller support frame sealing protective cover.

[0007] The aforementioned high-efficiency grinding mill has a grinding roller support frame comprising two horizontal frames and one vertical frame. One end of the two horizontal frames is fixed to the grinding mill rotor, and the other end of the two horizontal frames is connected through the vertical frame. The two horizontal frames, one vertical frame, and the grinding mill rotor form a rectangular frame. Grinding rollers are mounted on the vertical frame via bearings. Grinding roller springs are mounted on both horizontal frames, and a grinding roller support frame sealing protective cover is mounted on the outside of the grinding roller springs. The top and bottom of the vertical frame are respectively fixed to the ends of the corresponding grinding roller springs.

[0008] The aforementioned high-efficiency grinding mill has four grinding roller support frames arranged radially on the mill rotor, with one grinding roller installed on each grinding roller support frame.

[0009] Compared with the prior art, the present invention has the following technical effects:

[0010] This utility model patent utilizes a high-pressure grinding roller rotating at high speed within a grinding ring to crush the material requiring fine grinding between the roller and the grinding ring. Fine powder of the correct particle size is collected and stored by a classifier, while unqualified material is returned to the grinding chamber of the mill for further crushing. This cyclic grinding process saves significant energy and reduces material crushing costs compared to a grinding mill. The adjustable springs on the grinding rollers allow for the crushing of materials of different particle sizes, further reducing production costs.

[0011] This invention relates to a mechanical device that pulverizes raw materials by crushing them between a high-pressure roller and a grinding ring. It is a fine crushing device for materials with a particle size between that of a crusher and a mill. The crushed material has a high powder content. For limestone materials with medium to low hardness, the output fine powder rate of small and medium-sized roller mills (with a particle size of less than 80-100 mesh) can reach over 80%, while large roller mills can achieve over 80% fine powder rate for output particles smaller than 300 mesh. This roller mill uses significantly less motor power than a mill, resulting in a significantly lower cost per ton of material, achieving the goal of "more crushing, less grinding" and reducing energy consumption.
