Abstract
The present invention discloses the process of preparing white grinding medium with bauxite as main material. The materials include bauxite 75-95 wt%; plasticizer of kaolin, clay or artificial plasticizer 1-10 wt%; fluxing agent of one or several of sodium tripolyphosphate, CaCO3, BaCO3, baked talcum and light burnt magnesia 1-20 wt%. The preparation process includes the following steps: 1. ball milling bauxite while adding plasticizer and fluxing agent; 2. stoving the milled slurry; 3. forming grinding medium blank; and 4. sintering to obtain grinding medium product. The present invention has low production cost, low sintering temperature, low power consumption, low resource consumption, high product performance and other features.
Description
Technical field
The present invention relates to grinding medium manufacturing technology field, particularly is the method for feedstock production white rubbing medium with the bauxitic clay.
Technical background
Grinding medium is widely used in the raw-material attrition process of various industries fields such as mineral, pottery, coating, makeup, is the requisite of a lot of industries, and therefore a large amount of market arranged.And the main raw material of grinding medium is an aluminum oxide, and its market value is higher.Fine alumina ceramic exists performance and price contradiction at present, the grinding medium that the production color is white, performance is high will use expensive aluminum oxide, and the natural bauxitic clay mineral that utilize China's abundant are main raw material, and preparation color grinding medium white, that performance is high yet there are no report.
Summary of the invention
Use expensive aluminum oxide when the objective of the invention is the grinding medium white at the production color, that performance is high, for saving cost, so utilize natural bauxitic clay mineral to be main raw material, add a small amount of other auxiliary agents, prepare the grinding medium that color is white, performance is high.
The raw material weight per-cent of grinding medium is bauxitic clay 75-95%; Softening agent 1-10%; Fusing assistant 1-20%.Softening agent is a kind of in kaolin, clay and the artificial softening agent; Fusing assistant is tripoly phosphate sodium STPP and CaCO
3, BaCO
3, burn in talcum, the light calcined magnesia one or more.
Concrete steps are as follows:
(1) with bauxitic clay: water=1: 1-1.5 put into the ball grinder ball milling 24-48 hour, then ball milling gained slip was dried;
(2) in the material of (1) step gained, added softening agent and fusing assistant ball milling 24-48 hour together, material: water=1: 1-1.5, take out the slip oven dry then;
(3) (2) step gained raw material is adopted plastic molding or isostatic pressing, make the grinding medium base substrate;
(4) (3) step gained grinding medium base substrate was made product at 1000-1350 ℃ of sintering 1-3 hour.
Production cost of the present invention is low, firing temperature is low, and less energy consumption, resource consumption are few, and bauxite raw material is to contain Al
2O
3Reach the natural mineral more than 60%, can be applicable in the existing production of grinding medium factory, made product has characteristics such as color is white, performance height.
