Abstract
The invention discloses and aims at providing a method for producing modified mechanism sand and special admixture for dry-mixed mortar. Lime stone chips are utilized as raw materials in the method and the method is characterized by including the steps as follows: A, powder selection, putting the lime stone chips in a powder selecting machine, separating mechanism sand, soil powder, stone powder and coarse stone ballast; B, modification of stone powder, putting the stone powder obtained from the step A into a modification mill for treatment to obtain modified stone powder; C, mixing, putting the modified stone powder obtained from the step B into a mixer and adding a thickening agent , a dispersing agent and a water reducing agent to obtain the special admixture for the dry-mixed mortar; and D, sand making, putting the coarse stone ballast obtained from the step A into a sand making machine for treatment to obtain fine stone ballast, mechanism sand and stone powder, wherein the stone powder returns to the modification mill and the fine stone ballast returns to the sand making machine. The method is mainly used for producing the modified mechanism sand and the special admixture for the dry-mixed mortar.
Description
Technical field
The present invention relates to the method for a kind of production modification mechanism sand and special additive, relate in particular to a kind of method of producing dry-mixed mortar with modification mechanism sand and special additive.
Background technology
Produce dry-mixed mortar with general machine-processed sand, have that workability is poor, the mortar bleeding serious, the admixture consumption is big, earth impurity is many in the sand, shortcoming such as cause that the mortar constructing operation of producing with machine-processed sand is poor, cost height, intensity are low.
Summary of the invention
The object of the present invention is to provide a kind of method of producing dry-mixed mortar, to overcome above-mentioned shortcoming with modification mechanism sand and special additive.
For achieving the above object, technical solution of the present invention is: a kind of method of producing dry-mixed mortar with modification mechanism sand and special additive, utilize race to make raw material, it is characterized in that following steps: A, select powder, race is put in the powder separating machine, isolated machine-processed sand, mud powder, stone flour and rubble slag; B, stone flour modification are put into processing in the modification mill with the stone flour that steps A obtains, and obtain the modification stone flour; C, mixing, the modification stone flour that step B is obtained drop in the mixing machine and add viscosifying agent, dispersion agent, water reducer, obtain the dry-mixed mortar special additive; D, system sand are handled in the rubble slag input system sand machine that steps A is obtained, and obtain microlith slag, machine-processed sand and stone flour, and this stone flour returns the modification mill, and the microlith slag returns the sand machine of making.
The invention has the beneficial effects as follows: 1. it has recycled a large amount of aggregate chips (race) that Wingdale processing industry is produced, and dry production is used for the modification mechanism sand of dry-mixed mortar, not only saves the oven dry energy but also save limestone resource.2, a large amount of stone flours that utilize production mechanism sand to produce, the mixed chemical additive is produced the dry-mixed mortar special additive simultaneously again, has not only turned waste into wealth to economize on resources but also save the broken powder process energy, also protects environment.3, by physically modified to machine-processed sand, be that powder separating machine is got rid of the mud powder of aggregate chips (race) the inside, reach the standard of building sand, by the content of stone powder in the powder separating machine controlling mechanism sand, make it to reach optimum gradation, with workability and the intensity of improving dry-mixed mortar; 4, spending except that argillous stone flour grinds to handle through modification makes epigranular mellow and full, use mixing machine and polymer masterbatch (viscosifying agent again, dispersion agent, water reducer) becomes the dry-mixed mortar special additive after the mixing, in machine-processed dry-mixed mortar, mainly play the thickening water conservation, disperse cement, effect such as gain in strength, join in the machine-processed sand, improve every performance of dry-mixed mortar: increase workability, improve to build and smear efficient, reduce and to land ash, save cement and lime putty, overcome and flake, common faults such as cracking, full degree of mortar at bed joint height in building by laying bricks or stones has freeze proof after the sclerosis, antiseepage, durable, effects such as cracking resistance.
Description of drawings
Accompanying drawing is a process flow sheet of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention and embodiment thereof are described in further detail.
Referring to accompanying drawing, the present invention utilizes race to make raw material, it is characterized in that following steps: A, select powder, race is put in the powder separating machine, isolate machine-processed sand, mud powder, stone flour and rubble slag; B, stone flour modification are put into processing in the modification mill with the stone flour that steps A obtains, and obtain the modification stone flour; C, mixing, the modification stone flour that step B is obtained drop in the mixing machine and add viscosifying agent, dispersion agent, water reducer, obtain the dry-mixed mortar special additive; D, system sand are handled in the rubble slag input system sand machine that steps A is obtained, and obtain microlith slag, machine-processed sand and stone flour, and this stone flour returns the modification mill, and the microlith slag returns the sand machine of making.
