Cement processing raw material treatment method

Abstract

The invention relates to the technical field of cement processing and treatment and particularly relates to a cement processing raw material treatment method. The treatment method comprises the steps of regulating the ratio of raw materials including limestone, clay and iron powder through an automatic distribution device to meet the requirement of cement with different hardness; grinding the raw materials, namely enabling an electric motor to drive a grinding table to rotate through a speed reducer, enabling the materials to fall from a discharging device into the center of the grinding table through an air locking feeding device, throwing the materials to the edge of the grinding table under the action of a centrifugal force, and rolling and grinding the materials by a grinding roller; and homogenizing the raw materials, namely enabling the components of the raw materials to tend to be uniform and consistent in a reasonable coordination or pneumatic stirring way. The cement processing raw material treatment method is reasonable in design, convenient to treat and capable of favorably controlling the ratio of the raw materials through automatic equipment and favorably controlling the problems of nonuniform fineness of the raw materials, reaction inconsistence, great influences to clinker quality and high crude particle content through a fine grinding process.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a processing method for cement processing raw materials. Background technique [0002] Cement, 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. The history of cement can be traced back to the Dadiwan people in Qin'an, China 5,000 years ago, who laid a floor similar to modern cement. A mixture of lime and volcanic ash, which was later used by the ancient Romans in construction, is very similar to modern lime pozzolanic cement. The concrete made of cemented crushed stone not only has high strength after hardening, 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 def...

Problems solved by technology

[0004] However, the existing cement processing technology is rough, and the fine density of cement raw meal cannot be well controlled. The fineness of raw meal is uneven, and the reaction is inconsistent, which has a great impact on the quality of clinker. The problem of large coarse particles directly affects the quality of cement. unqualified
