sludge reducing apparatus for sand production facility

摘要

The present invention provides an apparatus for reducing sludge in a sand-producing facility, comprising: a classifying means 20 for classifying sand by particle size using crushed ore and water at a downstream side of the raw material separator 15; Water supply means (30) for regenerating and replenishing water circulated to be supplied to the classification means (20); A post-treatment means (40) for sending the residual soil generated by the classification means (20) and the water supply means (30) from the sludge storage tank (42) to the filter press (43) to produce a cake; And a control means (50) for controlling the classification means (20), water supply means (30), and post-processing means (40) with a set algorithm. Accordingly, the production of inorganic sludge, a waste, is minimized by causing the regression of raw materials from the downstream to the upstream process while classifying the sand into heavy and uncoated sands of different sizes in a short time by a plurality of classification means, and It has the effect of being able to respond flexibly.
