Sand making machine

Abstract

The invention discloses a sand making machine, which comprises a housing horizontally arranged, wherein the housing is cylindrical; a central cylinder is fixedly connected to the inner bottom surfaceof the housing; a first rotating plate is horizontally arranged above the central cylinder; a fixed ring is fixedly connected to the bottom surface of the first rotating plate; a fixed groove matchedwith the fixed ring is formed in the upper surface of the central cylinder; the fixed groove is annular; the fixed ring is rotationally connected with the fixed groove; the bottom surface of the firstrotating plate is fixedly connected with a main shaft; the main shaft is vertically arranged; the main shaft is rotationally connected with the inner bottom surface of the housing; the main shaft isfixedly connected with a first gear; and one side of the main shaft is provided with a first motor. According to the sand making machine, crushed materials are divided into two parts; one part of thecrushed materials performs centrifugal motion after being accelerated to impact on the other part of the crushed materials, and meanwhile, impacts on a crushing plate to perform primary crushing; andthe crushed materials are subjected to secondary crushing by a crushing roller, so that the crushed materials are crushed more thoroughly; the effect of crushing the crushed materials is better; and the sand making machine is more practical.

Description

technical field [0001] The invention relates to the technical field of stone crushing devices, in particular to a sand making machine. Background technique [0002] Stone crushers can be divided into medical stone crushers and mining stone crushers according to major categories. In principle, mining stone crushers are suitable for crushing a large number of hard rocks in mines. The typical granite output particle size is ≤40mm, accounting for 90%. For materials below 100-500 mm, its compressive strength can reach up to 350 MPa. It has the advantages of large crushing ratio and cubic particles after crushing. Crushing machinery with more than 50% material. [0003] Mining crushers are also called stone crushers, which refer to crushing machines in which the particle size of the discharge is greater than 3mm and accounts for more than 50% of the total discharge volume. It was invented by the British Hengan. The crushing operation is often based on the size of the feed and dis...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problems in the prior art that the single crushing process does not completely crush the crushed materials, it is difficult to meet the established standards, and the vibration causes damage to the components when the device is in operation.
