A device for processing raw materials of dry-mixed mortar and gravel

Abstract

The invention belongs to the technical field of building materials, and specifically relates to a dry-mixed mortar sandstone raw material processing device, which is used for drying sandstone raw materials. A rotating motor is vertically fixed on the top plate through the motor seat, and the output shaft of the rotating motor penetrates the top plate of the sealing cylinder and extends into the inside of the sealing cylinder; the top plate of the sealing cylinder surrounds the motor with an annular feeding port, and the upper part of the top plate is located at the edge of the feeding port A ring-shaped first baffle plate is installed at the center; a dispersing mechanism, a grinding mechanism and a drying mechanism are sequentially arranged in the sealed cylinder from top to bottom. When the sand and gravel raw material processing device of the present invention is used to dry the sand and gravel raw material, the sand and gravel raw material can be fully and uniformly dried, avoiding the occurrence of the sand and gravel raw material blocking the screening hole in the subsequent screening process , and can grind the surface of sand and gravel raw materials into a rounded shape, which improves the accuracy of the subsequent screening process.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a device for processing dry-mixed mortar and gravel raw materials. Background technique [0002] Dry-mixed mortar refers to a granular or powdery building material that is physically mixed in a certain proportion with dried and screened aggregates, inorganic gelling materials and additives, and can be used directly after mixing with water. Dry-mixed mortar plays the role of bonding, lining, protection and decoration in thin layers in the construction industry, and is widely used in construction and decoration engineering. The sand and gravel raw materials in the dry-mixed mortar are mainly quartz sand, river sand, broken limestone, etc. Before use, the sand and gravel raw materials containing impurities must be washed and dried, and then the sand and gravel raw materials must be screened. At present, the following problems exist in the drying of sand and g...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a dry-mixed mortar sandstone raw material processing device, aiming to solve the following problems existing in the current drying of sandstone raw materials: (1) the moisture on the surface of the sandstone raw material will make the sandstone raw material agglomerate, It makes it difficult for the sand and gravel raw materials to be fully and uniformly dried, which in turn causes the sand and gravel raw materials to block the screening holes in the subsequent screening process, which damages the equipment and reduces the screening effect; (2) The surface of the sand and gravel after drying There are many irregular sharp corners, which reduces the screening accuracy in the subsequent screening process
