Cement grinding and screening device

Abstract

The invention discloses a cement grinding and screening device. The cement grinding and screening device comprises a treatment frame, wherein supporting frames are symmetrically installed at the bottom of the treatment frame, a base is installed at the ends, away from the treatment frame, of the supporting frames, one side of the treatment frame is communicated with a material pushing pipe, and a dustproof cover is installed at the end, away from the treatment frame, of the material pushing pipe; a feeding port is formed in the side, away from the supporting frame, of the treatment frame, a sliding cover is connected to the position, close to the feeding port, of the inner wall of the treatment frame, a handle is installed at one side of the sliding cover, a discharging port is communicated with the side, away from the material pushing pipe, of the treatment frame, and a screen is fixedly connected to the position, close to the discharging port, of the inner wall of the treatment frame; and a hole cleaning device is mounted at the position, close to the treatment frame, of the inner wall of the treatment frame. According to the cement grinding and screening device, the purpose of effectively crushing large particles of cement raw materials is achieved, and it is guaranteed that the sizes of the particles of the cement raw materials are small, so that the particles are easier to use.

Description

technical field [0001] The invention relates to the technical field of cement, in particular to a cement grinding and sifting device. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. In the early years the mixture of lime and volcanic ash is very similar to lime pozzolanic cement, use it to glue concrete which made of crushed stone. After hardening, the cement not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, as an important cementing material, it is widely used in civil engineering, water conservancy, national defense and other projects. [0003] For example, Chinese patent CN109453847A proposes a cement crushing and grinding device, including a grinding shell, a feeding cylinder, a support column, a ba...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a cement grinding and sifting device, which solves the problem that the cement cannot be accumulated inside the sieve hole when the device is grinding the cement, and achieves a perfect sieve hole on the surface of the sieve. For the purpose of cleaning, the function of secondary crushing of large granular cement is realized, the crushing uniformity of the device is improved, and the hardened cement can be directly crushed, which saves time. The rebound device is installed to further improve the Work efficiency, effectively avoid the dust generated during cement grinding process from floating in the air, improve the air quality in the factory building, and ensure the on-site working environment and the health of personnel
