Abstract
The invention discloses a production technology of dry-process machine-made sand capable of replacing river sand. The production technology comprises the following steps: 1) raw material transport; 2) screening process; 3) secondary crushing; 4) classification screening: directly conveying the base material of which the particle size is greater than 4.75mm into a centrifugal crusher by conveying equipment, and grinding again; repeating the step; screening one third of the base material of which the particle size is less than 4.75mm by a linear sieve, wherein the rest two thirds of the base material replaces river sand; selecting the base material over 80 meshes from the one third of the base material screened by the linear sieve as special sand; and selecting the base material below 80 meshes from the one third of the base material screened by the linear sieve as special sand. The production technology disclosed by the invention is reasonable in design and simple in process; a large quantity of construction waste can be made into a river sand substitute meeting requirements while the construction waste of other particle sizes also can be used in other ways, thus, the problem of construction waste is solved, the use of river sand is reduced, and the environment is protected; and moreover, the cost is very low, and large-area popularization is facilitated.
Description
Technical field
The present invention relates to the processing technology of a kind of dry method mechanism sand replacing river sand.
Background technology
Current building waste has become as social effects of pollution, does not have other way to solve except burying etc..More existing factories utilize building waste to carry out brickmaking, but the brick quality so made does not pass a test, and life-time service can affect construction quality,
Additionally in architectural engineering, river sand is widely used, but the excavation of river sand needs to destroy the ecosystem in river course, and environment is significantly unfavorable.
So, for the technician, develop the processing technology of a kind of dry method mechanism sand replacing river sand; reasonable in design; technique is simple, it is possible to substantial amounts of building waste is made the succedaneum of satisfactory river sand, and the building waste of other particle diameters also can do other purposes simultaneously; firmly building waste; decrease the use of river sand simultaneously, protect environment, and very low cost; it is easy to spread, becomes a problem urgently to be resolved hurrily.
Summary of the invention
The technical problem to be solved in the present invention is to overcome drawbacks described above; the processing technology of a kind of dry method mechanism sand replacing river sand is provided; reasonable in design, technique is simple, it is possible to substantial amounts of building waste is made the succedaneum of satisfactory river sand; the building waste of other particle diameters also can do other purposes simultaneously; firmly building waste, decreases the use of river sand simultaneously, protects environment; and very low cost, it is simple to spread.
For solving the problems referred to above, the technical solution adopted in the present invention is:
A kind of processing technology of the dry method mechanism sand replacing river sand, it is characterised in that: step is as follows:
1), raw material transport: utilize construction waste as base material, pull with transport vehicle；
2), screening process: utilize screening machine by the base material of different-grain diameter；
Particle diameter is not less than the base material of 6cm, is transported in gyratory crusher；
Particle diameter base material between 3.5-6cm, is transported in jaw crusher；
Particle diameter is not more than the base material of 3.5cm, is transported in brickmaking machine as brickmaking sand.
3), second-time breakage: the base material that jaw crusher and gyratory crusher export is transported in centrifugal crusher, the base material after output is broken；
4), category filter: the particle diameter base material more than 4.75mm, be directly transmitted back in centrifugal crusher with conveying equipment, again pulverize；This step repeats；
The particle diameter base material less than 4.75mm, utilizes straight line shaker screening 1/3rd, and other remaining 2/3rds replacement river sands use；
Straight line shaker screening 1/3rd base materials, choose more than 80 orders as special sand, for binding sand, insulation sand；
Straight line shaker screening 1/3rd base materials, choose below 80 orders as special sand, for thin-coat plaster, cement self-leveling.
Owing to have employed technique scheme; compared with prior art; the present invention is reasonable in design, and technique is simple, it is possible to substantial amounts of building waste is made the succedaneum of satisfactory river sand; the building waste of other particle diameters also can do other purposes simultaneously; firmly building waste, decreases the use of river sand simultaneously, protects environment; and very low cost, it is simple to spread.
