Problems solved by technology

Even with the same main engine configuration, due to the different grinding characteristics of materials and unreasonable adjustment methods of process parameters, etc., the output of the system is uneven, the gap is large, and the power consumption of grinding is also uneven.

Embodiment Construction

[0007] 1. Roller press through type pre-grinding process system

[0008] Up to now, the grinding system is still used by a small number of enterprises. Generally, the processing capacity of the roller press is small. Although the production potential of the follow-up tube mill is rich, the front-end roller press does less work in one extrusion (roller The extrusion force of the press is 6000KN / m2-7000KN / m2, the ratio of the capacity of the roller press to the system is about 200%, and the power consumption per unit throughput is about 2.5kwh / t-3.0kwh / t), which is only equivalent to general extrusion Crushing function, during the extrusion process, a certain amount of side material can participate in the circulation, and the extruded material is directly put into the mill without classification (the 80um sieve of the 80um material after extrusion is 70%-80%, and the specific surface area is only 100m2 / kg About), the system production increase range is 20%-60%, and the average p...

Abstract

The invention relates to a cement grinding expert optimization system, namely a cement material bed finish-grinding process system (or called as a sphereless cement finish-grinding system). The cement grinding expert optimization system comprises a vertical mill cement material bed finish-grinding process system which consists of a vertical mill device, a high-efficiency powder concentrator, a dust collector and a fan, as well as a closed-circuit cement grinding process system which consists of a horomill (HOROMILL of French FCB), the high-efficiency powder concentrator, the dust collector and the fan. The novel dry-process cement clinker is dry and hard in grinding characteristic, poor in grinding easiness, and free from common open-circuit and close-circuit grinding flows of pretreatment measures before grinding, the impact-crushing capability of materials is low through the warehouse grinding body of the mill, and the system is low in grinding efficiency and high in electricity consumption. The grinding system with a crusher and rod mill pretreatment technology is only applicable to pipe mills with the diameter phi of 3.5m and below due to low treatment capability.

Description

Background technique [0001] With the continuous exchange of cement production technology and international counterparts, my country's cement industry has made great progress and development. Domestic cement design institutes, engineering technicians and scientific researchers from colleges and universities have developed a number of patented technologies and equipment with independent intellectual property rights, which have been successfully applied to the EPC project of export production lines, and have won good international praise. As far as cement grinding technology is concerned, due to factors such as the selection of grinding host equipment and pretreatment equipment, the process flow of new dry-type lines and grinding stations of different scales in China has its own characteristics, and the system output and grinding power consumption indicators Also different. Even with the same main engine configuration, due to the different grinding characteristics of materials a...
