Efficient dry method sand making production line

Abstract

The invention discloses an efficient dry method sand making production line. The efficient dry method sand making production line comprises a feeding device, a vibration crushing device, a belt conveyor, a vibration screening device, an efficient powder concentrator, a dust removal device, a control center and a hydraulic device. The feeding device is of a cylindrical structure. The feeding devicecomprises a material hanging device, a feeding port, a material containing device and a discharging port. The material containing device is provided with an infrared detection device. The infrared detection device detects the volume of materials in the material containing device and is connected with the control center. The feeding port is located above the material containing device, and the discharging port is located in the lower right side of the material containing device and is of a circular structure. The material hanging device comprises a mechanical arm and is connected with the hydraulic device. Power is provided through the hydraulic device, the material hanging device is connected with the control center, and the control center receives signals of the infrared detection deviceand controls the feeding speed of the material hanging device.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a high-efficiency dry sand production line. Background technique [0002] The machine-made sand production line is a kind of processing and production equipment that uses larger particle size stones as raw materials to produce finished aggregates of different specifications. The finished aggregate can meet the use requirements of the concrete industry, and is used to make up for the dwindling natural sand and stone and reduce the production cost of concrete and other building materials. [0003] The production process of the existing machine-made sand production line is as follows: the raw materials are transported to the feeding device through the elevator, and after being crushed and shaped by the feeding device to the sand making machine, they are classified by the screening screen, and the sand and gravel are screened in the screening screen. Finally, the sand that meets...

AI Technical Summary

Problems solved by technology

Stones that do not meet the requirements are returned to the sand making machine for crushing and shaping through the feeding device or the grading adjustment machine. The dust generated in the sand making production line is processed through the dust removal pipeline to the dust collector. However, in the existing sand making production line, The dust removal pipeline is generally only used for dust removal in the lifting stage, and the dust removal effect is average
