Embodiment 1

[0020] Raw material formula is by weight percentage:

[0021] Bauxite 40%, potassium feldspar 15%, clay 45%.

[0022] The chemical composition of the raw material is formed by weight percentage: bauxite (Gong County, Henan): SiO 2 (7.88), Al 2 o 3 (8557), TiO 2 (3.42), Fe 2 o 3 (0.84), CaO (1.01), K 2 O(0.84), Na 2 O (0.22); Potassium feldspar (Hunan Pingjiang feldspar): SiO 2 (65.22), Al 2 o 3 (19.18), Fe 2 o 3 (0.02), CaO(0.40), MgO(0.23), K 2 O(9.74), Na 2 O(4.20); clay SiO 2 (96-68), Al 2 o 3 (15-31), Fe 2 o 3 2 O(1-2), Na 2 O(0.5-1).

[0023] Mix 3 tons of the above raw materials according to the above ratio, add them to the ball mill, add water to the ball mill, and mill for 36 hours to make mud. Dried, then pulverized into powder by a pulverizer, put the powder into a mold box and put it into an isostatic press (manufactured by Qingdao Shuangying Electromechanical Equipment Co., Ltd., model LDJ400 / 4000-160) to press into a ceramic roller cylinder R...

Embodiment 2

[0026] Raw material formula is by weight percentage:

[0027] Aluminum oxide powder 70%, clay 20%, dolomite 7%, barium carbonate powder 3%

[0028] The chemical composition of raw materials is composed by weight percentage: aluminum oxide powder: Al 2 o 3 (99.99%); clay SiO 2 (96-68), Al 2 o 3 (15-31), Fe 2 o 3 2 O(1-2), Na 2 O(0.5-1); Dolomite: CaO>30%, MgO>21%; Barium carbonate powder: BaCO 3 (99.99%).

[0029] Mix 3 tons of the above raw materials according to the above ratio, add them to the ball mill, add water to the ball mill, and mill for 36 hours to make mud. After the mud absorbs iron and removes impurities, it is made into powder through a spray drying tower. The mold box is put into the isostatic press to press the rough blank of the ceramic idler cylinder, and then the rough blank is processed into a semi-finished ceramic idler cylinder by a lathe, and the semi-finished ceramic idler cylinder is fired at a high temperature to become a ceramic idler cylind...

Abstract

The invention relates to a preparation method for ceramic support roller cylinder body in belt conveyer, which comprises: mixing the raw material according to some proportion to prepare even powder; putting the powder into mould cabinet to press into blank with static pressing machine; refining the blank, sintering, grinding to obtain the product. this invention can promote the bending strength and abrasion resistance of the roller cylinder body and fit to production in scale.

Description

technical field [0001] The invention relates to a ceramic idler roller of a belt conveyor, in particular to a manufacturing method of the ceramic idler roller. Background technique [0002] In the prior art, the molding method of the ceramic idler cylinder is that after the raw material is formulated, it is ball milled by a ball mill, filtered by a filter press, extruded into a billet by a vacuum mud mill, dried for a long time, refined, sintered, and ground. to make. The bending strength and wear resistance of the ceramic idler cylinder produced in this way are not very satisfactory, and the time for drying the semi-finished product in the production process is relatively long, which is not conducive to rapid production in batches. Contents of the invention [0003] The purpose of the present invention is to provide a manufacturing method that can improve the bending strength and wear resistance of the ceramic idler cylinder and make production more convenient, thereby i...
