Abstract
Description
technical field
[0001] The invention relates to a building crushing device, in particular to a sandstone crushing and grinding device for construction engineering. Background technique
[0002] In the process of building construction, sand and stones of different particle sizes need to be used according to different building requirements. When screening sand and stones, the construction unit usually places an inclined sieve on the ground, scoops up sand and stones with a shovel and pours them directly. On the sieve, to achieve simple screening of sand and gravel, in this case, the screening of sand and gravel is not thorough, and the work efficiency is low, and the sand and gravel cannot be ground, and the quality of construction is difficult to be guaranteed. Therefore need a kind of sandstone grinding and screening device, sandstone is ground, and the sandstone of different particle size is screened, but general screening device easily causes sieve mesh blockage.
