Embodiment Construction

[0019] combined with figure 1 A mud sand recycling process of the present invention will be further described.

[0020] A kind of silt recycling process of the present invention comprises the following steps:

[0021] (1) Collection and washing: Set up a water circulation pool for stacking mud-sand-water mixture, and wash the mud and sand through water circulation;

[0022] (2) The first recovery: the washed mud-sand-water mixture is sequentially introduced into the circular vibrating screen group and the spiral classifier unit to extract 1.0-3.0mm fine sand;

[0023] (3) The mud and sand overflow water separated by the spiral classifying unit is introduced into the buffer water intake tank for collection;

[0024] (4) Pre-separation: The mud and sand overflow water is introduced into the cyclone group, the coarser mud and sand are discharged through the bottom outlet of the cyclone, and the mud and sand water mixed with finer particles is discharged from the cyclone overflo...

Abstract

The invention discloses a sand recycling process comprises the following steps: (1) collection and flushing; (2) first recovery; (3) converging; (4) pre-separation; (5) second recovery; (6) concentration treatment; (7) third recovery; and (8) wastewater recovery. The process provided by the invention is directed at mud and sand water recovery treatment of the quarry field, improves the fine sand recovery amount, carries out recovery of mud and sand particles three times respectively according to the particle sizes of different ranges, is conducive to recycling of fine sand after recovery, and recovers the separated liquid, and is conducive to cyclic utilization of water, thereby reducing the intake of production water, and lowering environmental pollution.

Description

Technical field: [0001] The invention relates to the technical field of ore processing, in particular to a mud sand recovery and reuse process. Background technique: [0002] A large amount of mud and sand will be produced during the production of crushed stones, but such mud and sand are generally waste materials and difficult to recycle. The recovery of mortar in the prior art generally uses a filter press for solid-liquid separation. This method can only recover mud and sand with a certain particle size, and the recovery amount is small, and the recovery utilization rate is low. Invention content: [0003] The invention provides a process for recovering and reusing mud and sand, which solves the problems of low recycling amount and low recycling rate in the prior art. [0004] The technical solutions of the present invention are as follows: a mud and sand recovery and reuse process is characterized in that it comprises the following steps: [0005] (1) Collection and ...
