Embodiment 1

[0035] Embodiment 1, by weight 75% low-quality bauxite clinker, 18% diaspore, 3% kaolin, 2% BaCO 3 , 2% dolomite and 0.3% sodium tripolyphosphate added to the total weight of the above five raw materials for batching. First, the main raw material-low-quality bauxite clinker is washed with water, selected to remove impurities, and the low-quality bauxite clinker after removal of impurities Soil clinker, diaspore, clay, BaCO 3 , dolomite and sodium tripolyphosphate are added to the ball mill according to the weight ratio, and an appropriate amount of water is added for two ball mills. First, coarse grinding is performed and passed through a 400-mesh sieve, and then a second fine grinding is carried out and passed through a 600-mesh sieve to make a slurry The fineness of the slurry is controlled between 0.3%-0.5% after 600 sieves, and the water content of the slurry is kept at 35%-37%. Blanks and mud blanks are dry-pressed into molds and then dried to make semi-finished cerami...

Embodiment 2

[0041] Embodiment 2, by weight ratio is 50% low-quality bauxite clinker, 40% diaspore, 6% kaolin, 4% BaCO 3 And add 0.3% sodium tripolyphosphate and 5% medium-grade bauxite clinker of the above four raw materials for batching, first wash the main raw material-low-quality bauxite clinker, select and remove impurities, and remove impurities Low-quality bauxite clinker, diaspore, clay, BaCO 3 And the added sodium tripolyphosphate and medium-grade bauxite clinker are added to the ball mill according to the weight ratio, and an appropriate amount of water is added to carry out ball milling twice. 600 mesh sieve to make slurry, so that the fineness of the slurry is controlled between 0.3%-0.5% of the 600 sieve, and the water content of the slurry is kept at 35%-37%. Put the slurry into the pool for wet cleaning to remove iron, and grade spray Pellet and homogenize to make a clay billet, which is dry-pressed and dried to make semi-finished ceramic balls, put the semi-finished cerami...

Embodiment 3

[0047] Embodiment 3, be 65% low-quality bauxite clinker, 30% diaspore, 3% kaolin, 2% dolomite and add 0.3% sodium tripolyphosphate and 10% middle-grade aluminum of above-mentioned four kinds of raw materials by weight For batching of bauxite clinker, the main raw material - low-quality bauxite clinker is washed with water, selected to remove impurities, and the low-quality bauxite clinker, diaspore, clay, BaCO 3 And the added sodium tripolyphosphate and medium-grade bauxite clinker are added to the ball mill according to the weight ratio, and an appropriate amount of water is added to carry out ball milling twice. 600 mesh sieve to make slurry, so that the fineness of the slurry is controlled between 0.3%-0.5% of the 600 sieve, and the water content of the slurry is kept at 35%-37%. Put the slurry into the pool for wet cleaning to remove iron, and grade spray Pellet and homogenize to make a clay billet, which is dry-pressed and dried to make semi-finished ceramic balls, put th...

Abstract

The invention discloses a process method for producing high-quality medium-alumina ceramic balls by inferior raw materials, which comprises the following steps: firstly washing a main raw material - inferior bauxite clinker with water, picking out to remove impurities, adding the inferior bauxite clinker with removed impurities, diaspore, clay, an efficient flux component and a diluent into a ball mill on a weight basis, performing ball milling twice with a proper amount of water, performing primary coarse milling and sieving by a 400-mesh sieve, performing secondary fine milling and sieving by a 600-mesh sieve, performing wet washing of the prepared slurry to remove iron, performing spray granulation and homogenization to prepare a mud blank, then performing dry-pressing, classification and molding with a mould, drying to prepare a semi-finished ceramic ball, charging the semi-finished ceramic ball into a kiln, sintering the ceramic ball at a preserved temperature of 1340 DEG C. The invention shortens the ball milling time, saves energy, reduces cost, uses a large amount of inferior raw materials, widens the range for material selection, produces high-quality medium-alumina ceramic balls with high strength, good wear resistance, and comparable application effect to existing medium-alumina ceramic balls, reduces production cost by 10-15%, is energy-saving and high-efficient, and facilitates healthy economic development.

Description

technical field [0001] The invention relates to a production process for ceramic balls, in particular to a production process for medium-alumina ceramic balls. Background technique [0002] As we all know, there are many types of aluminum-containing ceramic balls, including ordinary aluminum-containing ceramic balls, medium-aluminum ceramic balls, high-alumina ceramic balls, activated alumina ceramic balls, and inert alumina ceramic balls. It is non-toxic, odorless and has the functions of purification, adsorption, catalytic protection and drying. It can be used in chemical, petrochemical, fertilizer, pharmaceutical, smelting, building materials, gas and environmental protection industries. It has a wide range of uses. As the aluminum content of ceramic balls increases, medium-alumina ceramic balls, activated alumina ceramics and high-alumina ceramic balls have the characteristics of higher strength, better wear resistance, and higher density, and the use effect is also quit...
