Throwing Impact Crusher Sand Making Machine

Abstract

The invention discloses a cast impact type gravel sand making machine, belongs to the technical field of crushing machines, and provides a cast impact type gravel sand making machine. The sand making machine is high in crushing force; equipment is relatively good in abrasive resistance, and the prepared sand grains are uniform. According to the technical scheme of the cast impact type gravel sand making machine, a feeding hopper is arranged at the upper end of a machine body; a machine body bracket is arranged at the lower end of the machine body; casting impellers are arranged in the machine body, are located below the feeding hopper, and are driven through an electromagnetic speed regulation motor which is arranged in the machine body; an impact plate is arranged on the inner lateral wall of the machine body; a discharge opening is formed in the bottom end of the machine body, and is communicated with the middle of a wind cone on the machine body bracket; a draught fan is arranged at one end of the wine cone; the other end of the wind cone is communicated with a sand inlet of a sand forming barrel; a sand outlet is formed in the bottom of the sand forming barrel; and a dust removal opening is formed in the upper part of the sand forming barrel, and is communicated with a dust remover through an air hose. The cast impact type gravel sand making machine can be widely applied to the field of sand making.

Description

Technical field [0001] The projectile impact type crushed stone sand making machine of the present invention belongs to the technical field of crushers. Background technique [0002] The grain size and shape of crushed stone sand is different from that of natural sand. Natural sand is round and smooth, while machine-made sand is cubic. Machine-made sand has a larger specific surface area than natural sand, and concrete prepared with machine-made sand has higher strength. Secondly, the production of machine-made sand can be combined with the production process of crushed stone, which greatly reduces the production cost of machine-made sand. Finally, machine-made sand is conducive to the comprehensive utilization of mineral resources, which not only solves environmental problems but also improves the utilization rate of natural resources. The sand making machine originated in Germany. In 1924, the Germans produced the third-generation sand making machine with single and double rot...

Problems solved by technology

At present, most of the current domestic models are imitation foreign models, which are bulky and low in efficiency, especially the "rock-on-rock" model, the yield of which is only 30%, which is caused by disorderly and disorderly strikes

Moreover, the service life of domestic sand making machine wearing parts (throwing head, flow channel plate, material receiving plate, counterattack plate, impeller body) is generally lower than that of foreign advanced products
