Abstract

The invention relates to a process for sand washing with stone dust. The invention is characterized in that the process for sand washing with stone dust comprises the following steps: (1) performing filtering and water scrubbing to separate out fine sand, soil particles and water; (2) sending the separated rough sand into a crusher for crush with water; (3) separating the sand, soil particles and water which are recrushed, refiltered and rescrubbed and the mixture of the sand, soil particles and water which are crushed, refiltered and scrubbed at the first time; (4) separating the mixture of sand, soil particles and water and then obtaining the finished sand and the finished soil particles which can be used to improve soil, wherein the water can be recycled for use. The invention performs three-waste treatment and processing to the waste stone dust generated during the production in a quarry, uses the stone dust which contains dust, fine sand and rough sand in the quarry as the raw materials to produce the building sand, thereby not only saving the problem concerning the shortage of the natural fine aggregate resource, but also being favorable for the environment protection in a aggregate production place and reducing the stacking place of the quarry waste and the environmental pollution.

Description

A kind of processing method of stone flour washed-out sand
Technical field
The present invention relates to a kind of processing method of utilizing stone flour that the rubble field contains dust, fine sand and coarse sand for the stone flour washed-out sand of raw material production building sand.
Background technology
At present, the stone flour that stone quarry production is discharged is the waste in producing, and includes dust, fine sand and coarse sand.The quantity discharged of stone flour is very big in the annual rubble field, and all increasing every year.A large amount of waste stone powders will cause environmental pollution, not only will take a large amount of soils, and wasting manpower and material resources's maintenance of discharging again, also can cause second environmental pollution.The excessive collection of placer that picks up of cutting into a mountain for quarrying not only will destroy a large amount of arable lands every year, causes soil erosion, and can work the mischief to environment, the havoc eubiosis and natural landscape.Research and development stone flour washed-out sand is imperative, has promptly solved the natural fine nervous problem of resource of gathering materials, and is beneficial to again to gather materials the home environment protection and reduce the stacking occupation of land and the problem of environmental pollution of quarrying, rubble field waste.
Summary of the invention
The present invention has overcome the defective of above-mentioned existence, and purpose is the stone quarry to be produced the waste stone flour of discharging carry out disposal of three wastes processing treatment, and a kind of processing method of stone flour washed-out sand is provided.
The processing method content Description of stone flour washed-out sand of the present invention:
The processing method of stone flour washed-out sand of the present invention is characterized in that: the processing method of producing the stone flour washed-out sand comprises the following steps:
(1), with the waste that contains dust, fine sand and coarse sand that the stone quarry filters out, screen and wash, isolate fine sand, mud powder and water;
(2), send the coarse sand of separating to crusher and add the water fragmentation;
(3), screen once more after the fragmentation and wash, the coarse sand that filters out returns the crusher inlet, carry out fragmentation once more, sand, mud powder and the water that postsearch screening, washing are come out carries out separating treatment together with the mixture of the sand, mud powder and the water that screen, wash out for the first time;
(4), flow to the mixture of sand, mud powder and the water of separator, heavy sand rises and falls downwards, discharges from the pipeline of bottom, flows to sand water precipitation pond natural sedimentation; The mud mixture of light specific gravity is subjected to the effect of the current that eddy current and bottom enter, and discharges from the top of separator, by the effusive muddy water natural sedimentation of muddy water delivery pipe, is through the sand of post precipitation that finished sand, mud powder are used to improve the soil, water can recycle.
The processing method of stone flour washed-out sand of the present invention; the waste stone flour that solves stone quarry production discharge carries out disposal of three wastes processing treatment; utilize the stone flour that dust, fine sand and coarse sand are contained in the rubble field to be the raw material production building sand; promptly solved the natural fine nervous problem of resource of gathering materials, be beneficial to again and gather materials the home environment protection and reduce the stacking occupation of land and the problem of environmental pollution of stone quarry waste.
Embodiment
The processing method of stone flour washed-out sand of the present invention is achieved in that the processing method of producing the stone flour washed-out sand comprises the following steps:
(1), with the waste that contains dust, fine sand and coarse sand that the stone quarry filters out, screen and wash, isolate fine sand, mud powder and water;
(2), send the coarse sand of separating to crusher and add the water fragmentation;
(3), screen once more after the fragmentation and wash, the coarse sand that filters out returns the crusher inlet, carry out fragmentation once more, sand, mud powder and the water that postsearch screening, washing are come out carries out separating treatment together with the mixture of the sand, mud powder and the water that screen, wash out for the first time;
(4), flow to the mixture of sand, mud powder and the water of separator, heavy sand rises and falls downwards, discharges from the pipeline of bottom, flows to sand water precipitation pond natural sedimentation; The mud mixture of light specific gravity is subjected to the effect of the current that eddy current and bottom enter, and discharges from the top of separator, by the effusive muddy water natural sedimentation of muddy water delivery pipe, is through the sand of post precipitation that finished sand, mud powder are used to improve the soil, water can recycle.
