Technical Field

[0001] The utility model relates to the field of cement processing equipment, in particular to a composite cement mill partition plate device. Background Art

[0002] In the cement production process, the cement mill is one of the key equipment. The partition plate is used to divide the interior of the mill into different grinding areas, so that the material can be fully ground in the process of gradual refinement. However, the middle of the fence plate of the traditional partition plate is usually a closed support plate without sieve holes for support. Such a support plate only plays a supporting role and lacks the function of promoting material grinding.

[0003] For example, the utility model patent (application number: 201820235385.3) discloses a "cement mill baffle plate structure," and its specification discloses: It includes a circular baffle plate fixedly connected to the cylinder. The baffle plate is welded to the inner wall of the cylinder by a plurality of arc-shaped welded plates sequentially spliced together around the outer edge of the baffle plate to form a connecting ring. The welded plates are distributed along the inner circumference of the cylinder. This cement mill baffle plate structure is lightweight, easy to manufacture, and firmly connected to the cylinder. The above patent can demonstrate the shortcomings of the existing technology.

[0004] Therefore, we have made improvements to this problem and proposed a composite cement mill partition plate device. Summary of the Invention
