Abstract
The invention provides a production method for natural quartz sand. The natural quartz sand is prepared from natural quartz stones, diluted hydrochloric acid solutions with the concentration of 14%-18% and water. The production method has the advantages of being simple in technology, little in equipment investment, low in cost, capable of being produced in batches, easy to operate and free of environmental pollution.
Description
[technical field]
The invention belongs to natural stone diamond stone manufacture field, espespecially a kind of with the method for natural stone diamond stone for primary industryization production natural siliceous sand.
[background technology]
Natural siliceous sand is a kind of silicate minerals of hard, wear-resisting, stable chemical performance, and its main mineral constituent is silicon-dioxide, and relative density is 2.65, its chemistry, calorifics and mechanical property have obvious anisotropy, be insoluble to acid, fusing point about 1730 DEG C, has higher fire performance.Natural siliceous sand is of many uses, as the industry such as glass, pottery and refractory materials, metallurgy, casting, building, chemical industry, machinery is all no lack of the figure of quartz sand.
[summary of the invention]
The object of the present invention is to provide a kind of method of suitability for industrialized production natural siliceous sand.
To achieve these goals, the production method of a kind of natural siliceous sand of the present invention can adopt following technical scheme: a kind of production method of natural siliceous sand, and its raw material used comprises: the dilute hydrochloric acid solution of natural stone diamond stone, concentration 14%-18%, water; Described production method is as follows:
A. natural stone diamond stone is sent into rinsing machine, with high pressure water washing, the dirt settling of natural stone diamond stone outside surface is removed;
B. again the natural stone diamond stone after cleaning is sent into sheller, the Calusena lansium of natural stone diamond stone outside surface is removed;
C. then natural stone diamond stone is sent into crusher, make quartzite be split into granular quartz sand;
D. again quartz sand is sent into sour pond, soak 25-30 hour with the dilute hydrochloric acid of concentration 14%-18%;
E. the natural siliceous sand in sour pond is pulled out, continue to be fed into rinsing machine high pressure water washing;
F. Tumble Dry natural siliceous sand particle again, and bake out temperature is 60 DEG C-75 DEG C, and drying time is 2.0-3.5 hour;
G. natural siliceous sand is sent into magnetic separator, the quartz sand containing magnetic, containing metal and metal oxide in magnetic separator Adsorption quartz sand, after 0.2-0.3 hour, magnetic separation terminates, and the quartz sand after magnetic separation is sent into vibratory screening apparatus and carries out classification, classify according to different size.
Compared with prior art, the present invention has following beneficial effect: in the present invention production method have that technique is simple, facility investment is few, cost is low, can be mass, the advantage of simple to operate, non-environmental-pollution.
