Abstract
Description
technical field
[0001] The invention relates to a grinding device, in particular to a vibration-vibration integrated sand and gravel screening device for concrete preparation. Background technique
[0002] Sand and gravel are commonly used in building decoration, and sand and gravel refer to a loose mixture of sand grains and crushed stones. In geology, mineral or rock particles with a particle size of 0.074~2mm are called sand, and those with a particle size larger than 2mm are called gravel or breccia (the difference between the two lies in the degree of rounding, see the entry conglomerate and sandstone for details. ). If most of the gravel in the sand is gravel, it is called sand gravel. Some people also refer to sandstone as sandstone in daily life.
[0003] Sand and gravel need to be screened before use. Sand and gravel with different particle sizes have inconsistent effects, so they need to be screened. In the prior art, the work throws sand and gravel onto the scr...
