Description

A wear-resistant hammer head high fineness breaking device

Technical Field

The utility model relates to the technical field of cement production, in particular to a wear-resistant hammer head high-fineness breaking device.

Background Art

In the current design of cement raw materials and clinker grinding, roller combined grinding system is mostly used. The roller press is used to crush and pre-grind the coarse clinker and the slag with poor grindability, which can achieve the effect of increasing production and reducing consumption. However, the roller press will cause roller surface wear after long-term use. At the same time, there are inherent defects in the working process of the roller press, resulting in a large proportion of coarse particles in the material cake, making it difficult for the subsequent ball mill to adapt to the material conditions, affecting the system output.

The dispersing and classifying machine is a kind of material cake dispersing and sorting equipment, which has the functions of dispersing the material cake and grading the particles. It is usually used in conjunction with a roller press to form an independent extrusion dispersing circuit.

The scattering method of the scattering classifier adopts the principle of centrifugal impact crushing. The material after being squeezed by the roller press is in a dense cake shape, which is fed continuously and evenly from the symmetrically arranged feed ports and falls on the scattering disk with hammer-shaped convex rib lining. The main shaft drives the scattering disk to rotate at a high speed, so that the material cake that falls on the scattering disk is accelerated to separate from the scattering disk. The material cake is thrown out at a high speed along the tangent direction of the scattering disk and then hits the impact lining and is crushed.

Since the material breaking process is continuous, the material rebounding from the impact liner will be more fully crushed by the continuous high-speed flying material from the breaking disc. The broken material falls through the annular channel and falls evenly into the grading area.

In the existing scattering and classifying machine, the impact liner is installed in the scattering and classifying machine with an integrated design, which causes the impact liner to be damaged during use. During its replacement, the impact liner is difficult to disassemble and the disassembly and assembly takes a long time.

For this reason, we propose a wear-resistant hammer head high-fineness breaking device to solve the existing problems.

At this time, an external power device is connected to drive the main shaft to rotate, so that the scattering disk rotates, and the material cakes that fall on the scattering disk are accelerated to break away from the scattering disk. The material cakes are thrown out at high speed along the tangent direction of the scattering disk and then hit the impact plate and are crushed. Since the material scattering process is continuous, the material rebounding from the impact plate will be subjected to another violent impact by the material continuously flying out of the scattering disk at high speed and be crushed more fully. The scattered materials fall evenly through the area between the shaft block and the bottom ring to the grading area of the wear-resistant hammer scattering classifier below.

Furthermore, when the impact plate needs to be replaced, the top plate can be removed, and each single arc-shaped impact plate can be pulled out from the positioning strip. When reinstalling, the positioning groove on the new impact plate can be inserted into the corresponding positioning strip;
