Single-motor double-roller hydraulic sand making machine for extruding and grinding materials

Abstract

The invention provides a single-motor double-roller hydraulic sand making machine for extruding and grinding materials, and relates to the technical field of sand making equipment. The feeding hopper is fixedly installed at the top of the fixed base, the use distance of the positioning frame plates can be freely adjusted, and therefore the distance between the two sand making rollers can be adjusted, the device can crush materials into gravel with different particle sizes for use, adaptability is high, the use requirements for crushing and sand making of the materials with different particle sizes can be met, and the device is suitable for popularization and application. The sand making machine can be used for crushing harder materials step by step, is extremely high in adaptability, and solves the problems that the distance between two crushing rollers of an existing sand making machine is fixed, different sand making machines need to be selected when sandstones with different particle sizes are produced, the adaptability is extremely poor, and the harder materials need to be crushed in sequence from large to small, so that the production efficiency is high. And different types of sand making machines are also needed, so that the practicability is poor.

Description

technical field [0001] The invention relates to the technical field of sand-making equipment, in particular to a single-motor double-roller hydraulic sand-making machine for extrusion and grinding of materials. Background technique [0002] Sand making machine is the core equipment in sand making industry and stone shaping field. It has become the mainstream design in metal ore crushing, quartz sand production, steel slag treatment and other fields. , Concrete mixing plants, etc. provide high-quality sand and gravel aggregates. [0003] However, as far as the current traditional sand making machine is concerned, it makes sand by crushing materials with double rollers, and the distance between the two crushing rollers is fixed, so that the crushing particle size of the material is fixed for a fixed type of sand making machine, and it can be used in different production Different sand making machines need to be selected for the particle size of sand and gravel, which has extr...
