A vertical shaft impact sand making machine

Abstract

The invention relates to the field of mining equipment, in particular to a vertical shaft impact sand making machine, which includes a casing, a feeding port, a feeding hopper and a crushing chamber. The lower side is provided with a crushing chamber, the left and right sides of the bottom of the crushing chamber are provided with fixed blocks fixedly connected with the casing, dust removal devices are provided on both sides of the crushing chamber, and shock absorbing pads are provided at the bottom of the fixed block. In the present invention, by setting the feeding hopper , can realize the adjustment of the throwing and blanking flow rate, and effectively solve the problem of excessive dust in the crushing process of the sand making machine by setting the dust removal device, and can realize the dust removal water by setting the first filter layer and the second filter layer Purify and realize the recycling of water resources. Through the motor, the rotating shaft and the crushing cavity can rotate in the opposite direction, which is beneficial to improve the crushing efficiency of the sand making machine.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a vertical shaft impact sand making machine. Background technique [0002] In the field of mining equipment, vertical shaft impact crusher is also known as sand making machine. Production of mountain rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, artificial sand from stone chips, construction aggregates, road fabrics, cushion materials, asphalt concrete and cement concrete aggregates, and various Fine crushing and coarse grinding of various metallurgical slags, especially for medium-hard, extra-hard and abrasive materials such as silicon carbide, corundum, sintered bauxite, magnesia, etc. The main shaft group drives the rotor group to rotate at a high speed, and the rotor group throws the middle part of the material at a high speed inside the crushing cavity assembly and collides with the surrounding blanking materials, through "rock hitting rock" and ...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing vertical shaft impact sand making machine, the structure of the crushing chamber assembly is single, the crushing efficiency of the sand making machine is reduced, and at the same time, the flow of materials cannot be adjusted, resulting in the inability to adjust the flow of throwing and blanking in daily use. , cannot meet different crushing needs, and the existing sand making machine will generate a large amount of dust due to the high-speed movement of the rotor during the crushing process, and the productive dust generated is too large, causing dust pollution and affecting the health of construction workers. Therefore, in view of the above status quo , there is an urgent need to develop a vertical shaft impact sand making machine to overcome the deficiencies in current practical applications
