Single-driving-roller clearance-free sand maker

Abstract

The invention discloses a single-driving-roller clearance-free sand maker, and relates to the technical field of crushing equipment. The single-driving-roller clearance-free sand maker is composed of a rack 2, a power device, a movable roller 9, a fixed roller, a fixed roller bearing seat 7 and a pressure regulating device; the pressure regulating device comprises a pressure regulating power component, a pressure regulating component, a pressure regulating and applying component, a pressure regulating guide component and a pressure regulating transmission component. The single-driving-roller clearance-free sand maker has the characteristics of simple structure, convenience in maintaining, low running cost, long running cycle, high sand formation rate and the like, can be used for preparing sands for construction by utilizing materials including sand stones, cobblestones and the like, also can be used for front breaking and grinding of a grinding system, and can be widely applied to the fields including construction, construction materials, mines and the like.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a single-drive roller gapless sand making machine. Background technique [0002] With the continuous development of the economy, industrial buildings and civil buildings have also developed rapidly. The source of river sand used to make concrete and wall plastering mud mainly relies on panning from rivers. After decades of panning, combined with panning The excavation is disorderly, and its reserves are getting less and less. Moreover, the normal flow direction of the existing river course has been seriously damaged, and the ecological environment of the river has been affected. For this reason, in recent years, a kind of equipment that utilizes cobblestone, sandstone, hemp stone etc. in the river to prepare building sand grains has appeared on the market, namely: sand making machine. At present, there are two main principles of sand making machines: one is to use hig...

AI Technical Summary

Problems solved by technology

At present, there are two main principles of sand making machines: one is to use high-speed rotating impact to achieve crushing and sand making. This type of sand making machine generally has the disadvantages of high energy consumption, large wear, and high maintenance costs; Roller extrusion is used to achieve crushing and sand making, but most of them have the disadvantage of less adjustment range
