Vibratory screening mechanism for vertical sand making machine

Abstract

The invention discloses a vibratory screening mechanism for a vertical sand making machine. The vibratory screening mechanism comprises a vibratory screening box, two vibration mechanisms, a rotatingmechanism and a base, wherein a screening plate and a first spring are arranged in the vibratory screening box, the vibration mechanism comprises a first motor, a cam, a driven wheel and a second spring, the rotating mechanism comprises a second motor, a rotating shaft and an impeller, the vibration mechanisms and the rotating mechanism are arranged below the vibratory screening box, the rotatingmechanism is arranged between the two vibration mechanisms, and the base is arranged below the vibration mechanisms and the rotating mechanism. The vibratory screening mechanism has the advantages ofbeing simple in structure and better in vibratory screening effect, and the vertical sand making machine using the vibratory screening mechanism is high in crushing efficiency and good in crushing quality.

Description

technical field [0001] The invention relates to the technical field of mining crushing and sand making equipment, in particular to a screen vibration mechanism for a vertical sand making machine. Background technique [0002] Sand making machine is also called sand making machine, sand making machine and sand making machine. It is a special machine for producing sand and stone for construction. It is widely used in various ores, cement, refractory materials, aluminum where clinker, corundum, Glass raw materials, machine-made building stones are made of gold slag, especially for high-hard, extra-hard and wear-resistant materials such as silicon carbide, corundum, sintered bauxite, and beautiful sand, which are more effective than other types of crushers; suitable for sand making machines It is suitable for the crushing and shaping of soft or medium-hard and extremely hard materials; in the field of existing mining equipment, the working principle of the sand making machine is...

[0002] Sand making machine is also called sand making machine, sand making machine and sand making machine. It is a special machine for producing sand and stone for construction. It is widely used in various ores, cement, refractory materials, aluminum where clinker, corundum, Glass raw materials, machine-made building stones are made of gold slag, especially for high-hard, extra-hard and wear-resistant materials such as silicon carbide, corundum, sintered bauxite, and beautiful sand, which are more effective than other types of crushers; suitable for sand making machines It is suitable for the crushing and shaping of soft or medium-hard and extremely hard materials; in the field of existing mining equipment, the working principle of the sand making machine is to divide the material into the throwing material in the middle and the blanking material in the periphery, and the main shaft group drives the rotor group to rotate at a high speed. The rotor group throws out the material in the middle at a high speed and collides with the surrounding material, and crushes the material in the way of "rock hitting rock" or "rock hitting iron". In the vibration mechanism of the vertical sand making machine, this method crushes the material It will cause damage to the screening vibration structure and reduce the efficiency of the mineral processing process; moreover, the screening effect of the existing screening vibration mechanism is poor, reducing the quality of the output
