Sand grinding equipment

Abstract

The invention discloses sand grinding equipment. The sand grinding equipment comprises a support, a grinding box, a first rotating shaft, a driving device and at least one grinding roller, wherein the grinding box is mounted on the support; a feed port is formed in the upper part of the grinding box; a discharge port is formed in the lower part of the grinding box; a discharge door is detachably mounted in the position corresponding to the discharge port of the grinding box; the first rotating shaft is rotationally mounted in the grinding box; the driving device is connected with the first rotating shaft and drives the first rotating shaft to rotate; each grinding roller comprises a main grinding roller body and a second rotating shaft, the main grinding roller body is rotationally mounted on the second rotating shaft, the second rotating shaft is mounted on the first rotating shaft through an elastic piece, and the second rotating shaft and the first rotating shaft are perpendicular to each other in the axial direction. According to the sand grinding equipment, the grinding quantity of materials each time can be increased, and the grinding effect of the materials can be guaranteed effectively.

Description

technical field [0001] The invention relates to the field of wear-resistant ball casting and processing, in particular to sand grinding equipment. Background technique [0002] To ensure the quality of castings, it is necessary to control all aspects of the casting process. Before wear-resistant casting, it is necessary to carry out sand grinding process. In the past, sand grinding was done manually, and the workload of workers was heavy, but the effect of manual sand grinding Not good, resulting in a decrease in the quality of the casting. [0003] CN201900214U after the publication of China effectively solved the problem of high cost and poor effect of manual sand grinding, and the structure is simple and easy to promote, but when this patent is put into use, the amount of rolling materials in each rolling process is less, and In the case of uneven grinding, it is usually solved by taking out the material and adding it to the sand mill for multiple rolling. Although multi...

[0003] CN201900214U after the publication of China effectively solved the problem of high cost and poor effect of manual sand grinding, and the structure is simple and easy to promote, but when this patent is put into use, the amount of rolling materials in each rolling process is less, and In the case of uneven grinding, it is usually solved by taking out the material and adding it to the sand mill for multiple rolling. Although multiple rolling can solve the problem of uneven grinding to a certain extent, it increases the costs to the business and increases the time consumed by sand grinding
