Silicate cement production line

Abstract

The invention provides a silicate cement production line which comprises a raw material tower, a crusher, a first ball mill rotary kiln, a second ball mill and a storage tower, wherein the first ballmill and the second ball mill are located on the two sides of the rotary kiln respectively, and the crusher is arranged on one side of the first ball mill; the first ball mill is movably installed onone side of the crusher, the first spiral conveyor is movably installed between the first ball mill and the crusher, the raw material tower is arranged on one side of the crusher, the material storagetower is arranged on one side, away from the rotary kiln, of the second ball mill, and the third spiral conveyor is movably installed between the material storage tower and the second ball mill. Crushing and homogenizing are combined via the silicate cement production line, the occupied area and the production process are reduced, metal impurities in the crushed raw materials can be removed, a feeding port and a discharging port of the crusher can be prevented from being blocked, ground cement is screened, the cement with overlarge granularity is fed back into the ball mill to be continuouslyground, and the production quality of the cement is improved.

Description

technical field [0001] The invention relates to the technical field of Portland cement production, in particular to a Portland cement production line. Background technique [0002] Portland cement clinker mainly composed of calcium silicate, limestone or granulated blast furnace slag with less than 5%, and hydraulic cementitious material made of finely ground gypsum are collectively referred to as Portland cement; [0003] The simple production process of cement is two grinding and one burning, that is, the raw materials must be judged, crushed, ground and mixed to make raw materials. The mixed materials are ground together to become cement; [0004] Comparative patent: The Chinese patent discloses a movable modular cement production line with the patent application number CN201721420330.1, including a raw material batching module, a cement grinding module, a cement storage module, a cement packaging and shipping module, an electrical control system module, Common system m...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned device can be easily assembled and transported, it cannot remove the metal impurities in the raw materials and affect the quality of cement when the raw materials containing iron and other metal impurities are used for cement production. The area is large, the feed and discharge of the crusher are prone to blockage, and the ball mill has uneven grinding, resulting in the particle size of some raw materials not meeting the standard requirements
