Description

A kind of preparation method of cobble shaped ceramic grinding media

Technical field

The present invention relates to a kind of cobble shaped ceramic grinding medias and preparation method thereof, belong to ceramic grinding media field.

Background technology

Abrasive media is main material indispensable during ceramic system is standby, and grinder is converted mechanical energy by abrasive media For the crushing energy to material, principle be material particles are disperseed by means of friction, shearing and the collision between abrasive media and It is broken.The direct size of abrasive media, proportion, loadings etc. directly affect the scattered and grinding efficiency of sand mill.Usually we Prepare which kind of ceramics selects similar ceramic grinding media as far as possible:Prepare aluminium oxide(Al2O3)Ceramics selection Al2O3Ceramic grinding is situated between Matter prepares zirconium oxide(ZrO2)Ceramics selection ZrO2Ceramic grinding media prepares carborundum(SiC)Ceramics selection SiC ceramic grinding Medium.General ceramic grinding media is all spherical body, and what is be commercially available is also essentially spherical ceramic grinding media, still The preparation method of this kind of abrasive media it is more complicated similar with the process that ceramic system is standby, it is necessary to powder shaping, degreasing, sintering, Corase grinding and essence such as throw at the processes, and the cost is relatively high, and usually existing causes when not fine and close wear-resisting property to be difficult to reach fine and close The performance standard of block ceramic.

In order to solve the above-mentioned technical problem, the present invention devises a kind of preparation method of cobble shaped ceramic grinding media, The shortcomings that preparation method of the cobble shaped ceramic grinding media overcomes abrasive media preparation process complexity, and cost is higher, profit The carborundum prepared is smelted with industry(SiC), boron carbide(B4C)Wait block materials and discarded silicon nitride(Si3N4)Oxidation Zirconium(ZrO2), aluminium oxide(Al2O3)Ceramic block material, the abrasive media of irregular shape needed for preparation, the patent of invention utilize Ceramic block material and the discarded material preparation ceramic grinding media of ceramics are smelted in industry, and preparation method is simple, cost is relatively low, green Colour circle is protected, and applicability is wide, can be generalized to the preparation of other a variety of ceramic grinding medias.In addition, the cobble shaped ceramic grinding The preparation method of medium is simple for process, it can be achieved that industrialization large-scale production, is suitble to promote the use of.

The content of the invention

In order to overcome defect present in background technology, the technical solution adopted by the present invention to solve the technical problems is: A kind of preparation method of cobble shaped ceramic grinding media, step are:

(1)The ceramics or waste ceramic block that melting is obtained are impregnated with hydrochloric acid solution removes ferrous contaminants;Then rushed with water Wash, filter and dry or in 105 DEG C of baking ovens drying 1 it is small when standby use;

(2)By step(1)The spare ceramic block more than 5 millimeters is crushed;Broken ceramic block is sieved, is chosen Grain size is about 1-5 millimeters of particle;

(3)In step(2)Water or alcohol are added in the ceramic particle of the 1-5 millimeters prepared as solution, is then mixed Mill, treats that ceramic grain surface is smooth, in cobblestone shaped ceramic;

(4)By step(3)Airing or small in 105 DEG C of drying in oven 1 after the cobblestone shape ceramic particle washing prepared When, it places at dry, that is, is prepared into cobble shaped ceramic grinding media.

The ceramics or waste ceramic block that the preferred melting obtains are boron carbide, carborundum, silicon nitride, zirconium oxide or One or more in aluminium oxide.

The preferred step(1)Middle hydrochloric acid solution impregnate remove ferrous contaminants time >=10 it is small when.

The preferred step(1)Every liter of concentration >=0.005 mole of middle hydrochloric acid solution.

The preferred step(3)The mass ratio of middle ceramic particle and solution is 1: 1-3.

The preferred step(3)Middle mix grinding is ball milling, sand milling, Ball-stirring mill or airflow milling.

The preferred step(3)When middle mix grinding time >=10 are small.

The present invention devises a kind of preparation method of cobble shaped ceramic grinding media, the cobble shaped ceramic grinding media Preparation method overcome abrasive media preparation process complexity, the shortcomings that cost is higher, utilizes industry to smelt the carborundum prepared (SiC), boron carbide(B4C)Wait block materials and discarded silicon nitride(Si3N4)Zirconium oxide(ZrO2), aluminium oxide(Al2O3)Pottery Porcelain block materials, the abrasive media of irregular shape needed for preparation, the patent of invention using industry smelt ceramic block material with And the discarded material preparation ceramic grinding media of ceramics, preparation method is simple, cost is relatively low, environmentally protective, and applicability is wide, can push away Extensively arrive the preparation of other a variety of ceramic grinding medias.In addition, the preparation method of the cobble shaped ceramic grinding media is simple for process, Industrialization large-scale production can be achieved, be suitble to promote the use of.

Specific embodiment

Specific embodiment one, a kind of preparation method of cobble shaped ceramic grinding media, step are:
