Abstract
The invention provides a formulation and technology of medium-high-alumina ceramic balls. The medium-high-alumina ceramic balls comprise the following raw materials in percentage by mass: dolomite, barium carbonate, bauxite, chinastone and calcined fossil; the technology comprises the steps of wet grinding for twice, precipitating for twice, adding a binding agent for uniformly mixing and firing, so as to obtain the medium-high-alumina ceramic balls. With the adoption of the medium-high-alumina ceramic balls prepared by using the formulation and technology provided by the invention, the defects that the conventional medium-alumina ceramic balls and medium-high-alumina ceramic balls are relatively low in bulk density, higher in abrasion loss, lower in hardness, and not pure enough in color and luster, and the using function loss of the medium-high-alumina ceramic balls reaches or is close to the using function standard of high-alumina ceramic balls.
Description
Technical field
The present invention relates to the mill ball in industrial ceramics processing and other fields, specifically a kind of formula and technique effectively reducing the middle alumina porcelain ball of abrasion and energy consumption.
Background technology
Now commercially conventional abrasive product is divided into two kinds, and one is middle aluminium mill ball, and one is high alumina mill ball.Middle aluminium mill ball in use weares and teares greatly, often produce 10,000 tons of ceramic products need consume in about 60 tons, aluminium ball; High aluminium ball wearing and tearing are little, and often produce 10,000 tons of ceramic products and need consume about 12 tons, but the price of its costliness makes comparatively multi-user hang back, use range is less.
It is large that middle alumina porcelain ball overcomes middle aluminium ball milling consumption, the weakness that energy consumption is high, and its using property data is close to the performance index of high aluminium ball, but product price is about 60% of high aluminium ball price, is extensively easily accepted by a user use, and market potential is huge.
Summary of the invention
The invention provides a kind of formula and technique of middle alumina porcelain ball, adopt the porcelain ball that obtains of the present invention to overcome existing middle aluminium ball and middle high alumina spheroid close lower, wear away larger, hardness is lower, the defect that color and luster is pure not, and its using function loss reaches or close to the using function standard of alumina porcelain ball.
The present invention realizes above-mentioned purpose by the following technical solutions:
The formula of middle alumina porcelain ball and a technique, it comprises the raw material of following mass component:
Rhombspar 3-5%, barium carbonate 3-5%, aluminium vanadine 80%, porcelain stone 3-5%, calcining fossil 3-5%, bonding agent are some.
The formula of described a kind of middle alumina porcelain ball and technique, its manufacture craft is as follows:
1) first being pulverized by above-mentioned each raw material, is the particle of 0-3mm by raw material pulverizing to particle diameter, and by raw material screening to 40 order;
2) take corresponding raw material according to the mass component of above-mentioned raw materials, carry out first time wet-milling to 400 order after mixing, then carry out first time heavy slurry, the heavy slurry time is 24 hours;
3) by step 2) in carry out second time wet-milling to 800 order through the raw material of once heavy slurry, then carry out that second time is heavy starches, sinking the slurry time is 24 hours; After heavy slurry completes, the method for employing iron removal by magnetic separation is to carrying out deironing;
4) add bonding agent to stir, the raw material of gained in bonding agent and step 3) is mixed according to the ratio of 1:9, then stirs;
5) raw material in step 4) is carried out granulation through spray-drying tower, obtain 60-100 object raw material;
6) machine after the raw material cooling in step 5) is pressed into porcelain ball embryo, the size of porcelain ball embryo adjusts according to actual needs;
7) fired in high temperature pushed slab kiln by the porcelain ball embryo of mechanical pressing in step 6), firing temperature is 1400 DEG C, and the firing time is 40 minutes, has fired rear cooling and has namely obtained required product.
The present invention adopts technique scheme to have following beneficial effect:
In the present invention, alumina porcelain ball warp is crossed and is used compared with middle aluminium ball and general middle high aluminium ball because body is greatly close, the milling time of Similar types of materials obviously shortens, save electric energy, reduce the production cost of product, meanwhile, because of in alumina porcelain spheroid greatly close, take ball mill feed bin space little, increase the charge amount of ball mill feed bin, improve the split run output of manufacturing enterprise.Because middle alumina porcelain ball milling material is little, its life-span be the 3-5 of middle aluminium ball doubly, close to or reach work-ing life of high aluminium ball, obviously extend the timed interval of tip-in in process of lapping, decrease the number of times of tip-in in process of lapping, substantially increase labor productivity.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.
The formula of middle alumina porcelain ball and a technique, it comprises the raw material of following mass component:
