By adopting the production system and the production method, the problem that conventional machine-made sand is unreasonable in grading and poor in particle shape can be fundamentally solved. The production method comprises the following steps: crushing broken stones by virtue of a crushing machine, conveying the broken stones to a grading controller by virtue of conveying equipment, classifying machine-made sand and finely controlling the grading of the machine-made sand, returning unqualified materials to the crushing machine to be crushed again, adding a particle shape optimizing machine behind the grading controller, and optimizing the particle shape of the machine-made sand. According to the machine-made sand produced by using the method disclosed by the invention, the fineness modulus and stone powder content can be accurately adjusted, the machine-made sand is mellow and full in particle shape and less in edge and corner, the improvement of concrete performance can be facilitated, the consumption of water and cement can be saved, and huge economic benefits can be provided.
Description
Technical field
The present invention relates to Machine-made Sand production system and production method.
Background technology
China's engineering construction is in recent years fast-developing, and sand is as the important source material of engineering construction, and demand is increasing.But natural sand resource is day by day deficient, the demand that Machine-made Sand replaces natural sand just becomes increasing.
Vertical shaft impact crusher is the major equipment of production mechanism sand, but its Machine-made Sand produced exists obvious shortcoming: coarse particles is many, and fine particle is few, content of stone powder is high, grating is unreasonable, and need use with natural sand blending, the concrete class of configuration is low, workability is poor.
Original production system, if want the grating of Regulation mechanism sand, mainly contain two kinds of methods, one adopts impact cutting associating rod mill or pair roller to break joint sand manufacturing, one is sieved by air to adjust, but these two kinds of ways can not the precise controlling of realization mechanism sand grating.
Impact cutting associating rod mill or pair roller break joint sand manufacturing, if the character of raw material is different with particle diameter, or disintegrating apparatus is different, namely the Machine-made Sand grating of producing can change, thus the concrete quality of impact preparation, increase Cost of Concrete, reduce concrete work performance.
Air sieve mainly controls the fineness modulus of finished sand by the returning charge amount adjusting coarse sand, it can not carry out intense adjustment to the accounting of grade each in finished sand, and Machine-made Sand grating is the important indicator affecting its configuration concrete quality.
In addition, the Machine-made Sand rough that vertical shaft impact crusher is produced, corner angle are many, and during configuration concrete, the consumption of cement and water is large.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of high-quality Machine-made Sand production system and production method.The Machine-made Sand grating using this production system to produce is rationally controlled, and particle shape is good, can meet the specification of quality of concrete fine aggregate, and flow process is simple, easy handling.
The technical solution adopted in the present invention is:
A kind of high-quality Machine-made Sand production system, rubble, by after crusher in crushing, is transported to screening plant through handling equipment, Machine-made Sand is carried out classification, and wherein underproof material returns crusher and carries out again broken; Described screening plant is Gradation Control device, is used for the grating of fine control mechanism sand; After screening plant, add particle shape optimize machine, the particle shape of Machine-made Sand is optimized.
Above-mentioned Gradation Control device, comprises pre-point watch-keeping cubicle at the beginning of and a precise controlling room.Described first pre-point watch-keeping cubicle, under the acting in conjunction vibrating material scattering device and negative pressure device, the content of stone powder in controlling mechanism sand, and by thickness yarn spacer plate, most of coarse sand is kept off outside finished product Machine-made Sand; Described precise controlling room, will be divided into multiple grade through pretreated Machine-made Sand by vibration screening device, and control the accounting of corresponding grade in the end in finished product by the intense adjustment plate in each grade passage.
Above-mentioned particle shape optimizes machine, comprises body, rotor, transmission mechanism and electric motor, utilizes the high speed rotating of rotor, drives material to rotate, makes mutually to wash away between material, exchange views, fin cutting and corner angle, be optimized by the particle shape of Machine-made Sand.
Utilize the production method of above-mentioned any one high-quality Machine-made Sand production system, comprise following operation:
Rubble is broken for the broken process of Machine-made Sand;
The gradation adjustment operation of Regulation mechanism sand size fractionated ratio and content of stone powder;
The particle shape shape of Machine-made Sand being carried out to shaping optimizes operation.
Compared with prior art, the invention has the beneficial effects as follows:
(1) grating of Machine-made Sand can realize real-time accurate adjustment;
(2) the Machine-made Sand particle shape produced is mellow and full, smooth surface, and corner angle are few;
(3) with the Machine-made Sand configuration concrete that above-mentioned production system is produced, the consumption of water and cement can be reduced, improve concrete work performance, there is huge economic and social benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
