Wear-resisting wind guide cone with replaceable lining plate

Abstract

The invention provides a wear-resisting wind guide cone with a replaceable lining plate. The wear-resisting wind guide cone is composed of an upper round connector, a lower cone connector, the lining plate and bolt holes. When a vertical mill works, impact force generated by solid materials to the wind guide cone is totally borne by the inner wall lining plate of the wear-resisting wind guide cone with the replaceable lining plate, and the service life of a shell of the wind guide cone is prolonged. When the inner wall lining plate of the wear-resisting wind guide cone with the replaceable lining plate is damaged, an operator can loosen bolts connected with the lining plate to replace the lining plate, the maintenance work of disassembling the mill and taking out the wind guide cone is avoided, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the field of mining equipment, is suitable for the operation connection of a vertical mill, and in particular relates to a wear-resistant air guide cone with a replaceable liner. Background technique [0002] For cement processing enterprises, the vertical mill is to feed raw materials into the center of the grinding disc from the feed port through the air lock feeding device, and is thrown to the periphery of the grinding disc under the action of the centrifugal force field, and is crushed by the repeated grinding of the grinding roller. The pulverized materials come from the edge of the grinding disc, in which the powdery materials are taken up and sent out by the high-speed airflow at the lower part of the vertical mill, and the solid materials fall into the mill cavity by their own weight for re-grinding. The air guide cone installed in the chamber of the vertical mill is an important accessory to change the direction of th...

AI Technical Summary

Problems solved by technology

However, the air guide cone in the chamber of the vertical mill wears very quickly, and the wear resistance of the shell of the air guide cone cannot support the impact of the materials in the working chamber of the vertical mill for a long time, so the air guide cone needs to be replaced after a period of time, and It is troublesome to replace, which increases the labor intensity of the operator
