Sandstone separator for directly separating mixed sandstone according to different granule diameters

Abstract

The invention discloses a sand-stone separator which directly separates the sand-stone mixture into different particle sizes. , a third sieve and a fourth sieve, the lower ends of the first, second, third and fourth sieves are respectively erected with a discharge port, the upper end of the first sieve is connected to a feed port , the apertures of the first, second, third and fourth screens gradually decrease in sequence. The fully graded sand and gravel separator of the present invention combines four screens with different apertures on one separator, the apertures gradually decrease from top to bottom, and can separate fine sand (0.1~5mm) to block stones ( 300~500mm), aggregates of different particle sizes roll down from the outlets of the screens under the action of vibrators and springs for classification, and add water spray at the feeding port The device is used to facilitate full flushing and reduce the mud content of the aggregate, which not only improves the separation speed of the aggregate, but also improves the quality.

Description

technical field [0001] The invention relates to a sand-stone separator, in particular to a sand-stone separator which directly separates a sand-stone mixture into different particle sizes. Background technique [0002] Generally, the sand and gravel separator has only one sieve, which can only separate two kinds of aggregates: fine sand (0.1~5mm) and gravel and pebbles for concrete (5~25mm). A full-graded sand separator, which separates sand and stones of various particle sizes and uses them separately has become an urgent need. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of sand and gravel mixture that can directly separate the sand and gravel mixture into masonry rubble, paving stone, gravel pebbles for concrete, sand for concrete, sand for masonry plastering, etc. Sand and stone separator for diameter aggregate. [0004] In order to achieve the above-mentioned technical effects, the present invent...
