How to optimize the grinding process in Ball Mill for Alumina Ball:
1. In the situation of wet grinding
Usually,the total charges of the alumina balls in one ball mill should be not less than 55% of the total ball mill capacity.

Empirical formula of charged alumina ball quantity into ball mill:
M=3.14xR2xDxLx25%+1000
Remark M= charged alumina ball quantity(kg)
D=Alumina ball density(g/cm)
R=Radius of ball mill L=Ball Mill Length

Alumina grinding ball proportion:
For a bright new installed ball mill, the alumina balls proportion depends on the capacity of the ball mill and the fineness of
the grinding raw materials

Alumina ball recharge quantity
Recharge quantity=Primary ball quantity*Ball wear loss*Grinding time

2. In the situation of dry grinding:
Dry grinding is widely used in mining, ceramics industries, we developed alumina balls performed well on dry grinding situation with much lower wear-loss, it helps solve the problem of materials contamination.
The proportion of the alumina ball for dry grinding depends on the hardness and fineness of the grinding raw material, generally speaking, CIP formed grinding ball used for dry grinding.

Wear-loss testing method of alumina ball:
This method is the Chinese domestic testing method, put alumina ball samples into polyurethane jar, testing the wear loss in the unit time.
Firstly, put 4kg alumina ball and 4L water into the grinding jar, put the jar into the testing machine, grinding 2h on the revolution of 80 r/min. Take out the samples dry them and get weight M1.
Secondly, put the above samples again into the jar, add 4L water, grinding 24h on the same revolution of 80 r/min.
Thirdly, take out the samples dry and get weight M2.
Fourthly, testing the average diameter of the samples, get average diameter D.
Fifthly, wearloss calculation:
EWT(%o )=KD M 1-M2 )M 1
Empirical formula: EWT(%o)= (M1-M2)M1/24 /100*1000*D

Product Description
Ceramic packing balls also named inert alumina balls are manufactured from very high quality chemical-porcelain clay materials.
According to the different content of Al2O3,the packing ceramic ball is divided into: common ceramic ball, inert ceramic ball, medium alumina ball, high alumina ball and 99% alumina Ball, actived alumina ceramic ball, opening hole ceramic ball, micro porous ceramic ball, heat storage ceramic ball.

Let me introduce hot sales 92% Alumina Grinding Ball for Ceramic grinder
The microcrystalline wear-resistant alumina grinding ball is a high-quality grinding medium made of selected high grade materials,advanced molding technology and calcined in high-temperature tunnel kiln. Possessed with high density, high hardness, low wear,good seismic stability and good corrosion resistance the products are the most ideal medium for grinding glaze, blank and mineral powder processing, and are used as the grinding medium of ball mill in ceramics, cement, paint, refractory, inorganic mineral powder and other industries.
Inert 92% alumina ceramic balls Characteristics and advantages
1.High mechanical strength (Monolithic spheres will not split, crack or spall in use)
2.High temperature resistance
3.Lower water absorption
4.Quite excellent chemical stability
5.Can resist corrosion of acid, alkali and other organic solvent
6.Excellent thermal shock resistance (can withstand the temperature urgent changes occurred in production process)
7.Trouble-free reactor filling due to high crush strength
8.Will not plug catalyst bed, optimizing the process efficiency by keeping the pressure drop low and catalyst activity high
9.No contaminate catalyst due to maximize resistance to attrition, extending the catalyst Activity life and reduce the operation cost

Inert 92% alumina ceramic balls application:
Inert alumina balls are widely used as the covering or supporting media of the catalyst in the reactors and tower packing in many fields such as petroleum, chemical industry, chemical fertilizer, natural gas and environmental protection etc. The main role is to buffer the impact of liquid and gas to the catalyst in the reactor, protect the catalyst and improve the distribution of liquid and gas in the reactor.

Packing & Delivery

Application

In the petrochemical and fertilizer industries, it is widely used as a catalyst and catalyst carrier. Modern water-purifying activated alumina has adsorption characteristics and is therefore used as a desiccant for gases and liquids, as an adsorbent for gas purification, as a deionizing agent for drinking water, as a color and odor eliminating agent for industrial sewage.
It can be used together with household fluorine removal cylinders, and is an ideal drinking water defluoridation device in the family. The defluorination filter material can also be used together with the fluorine removal device of the water plant or the fluorine removal device for industrial use. Activation of fluorine removal filter for household fluorine removal equipment: dispose of aluminum sulfate solution (3 liters of water, 0.3 kg of solid aluminum sulfate), put alumina (AL2P3) defluoridation filter into the above solution, soak for 5-10 hours to discard The liquid (should be properly stirred during soaking), and then washed 3-5 times with water, each time with water about 2 liters, or regenerated by pH adjustment, the pH is controlled at 7.5. Activated alumina defluorination filter can be used continuously for 6-8 years. When the surface appears yellowish brown, the effect of removing fluorine is obviously reduced. This is caused by impurity pollution in the water. Therefore, it is best to treat it once every half a year with 3% dilute hydrochloric acid. The method of operation is the same as the regeneration method.

Physical properties
Moreover, it is required that the dissolution rate of alumina in the cryolite melt is fast, the bottom of the electrolytic cell tank is deep and deep; the heat insulation of the shell on the electrolyte is good; the moisture is not absorbed in the air, the flying loss is small, the fluidity is good, and the transportation is convenient. And to facilitate the automatic feeding of the electrolytic cell. All of these properties depend on the physical properties of the alumina.

The indicators used to characterize the physical properties of alumina are: angle of repose, α-Al203 content, bulk density, particle size and specific surface area, and wear coefficient.

Use and properties of alumina balls
1. The angle of repose. The alumina angle of repose refers to the inclination of the material naturally accumulating on a smooth plane. The alumina with a larger repose angle is more soluble in the electrolyte, and can be well covered on the electrolyte crust during the electrolysis process, and the flying loss is also small.

2. A-Al2O3 content. The content of a-Al2O3 in alumina reflects the degree of alumina roasting. The higher the degree of
calcination, the more a-Al2O3 content, the hygroscopicity of alumina decreases with the increase of a-Al2O3 content.
Therefore, alumina for electrolysis is required to contain a certain amount of a-Al2O3. However, the solubility of a-Al2O3 in the electrolyte is inferior to that of Υ-Al203.

3, the weight. The bulk density of alumina refers to the weight of a unit volume of material in a natural state. Aluminium, which generally has a small bulk density, facilitates dissolution in the electrolyte.

4. Particle size. The particle size of alumina refers to the degree of its thickness. The particle size of alumina must be appropriate, too coarse in the electrolyte to dissolve slowly, or even precipitate; the rules are easy to fly loss.

5. Specific surface area. The specific surface area of alumina refers to the total surface area of the sum of the outer surface area per unit weight of the material and the surface area of the inner pores. It is an important indicator of the level of material activity. Alumina having a large specific surface area has good solubility in an electrolyte and is active, but is hygroscopic.

6, wear coefficient. The so-called wear coefficient is the percentage change of the fractional content in the sample after the alumina is rubbed in a fluidized bed under controlled conditions. The wear coefficient is a physical indicator of the strength of alumina.

According to the physical properties of alumina, alumina can usually be divided into three types: sand, flour and intermediate. These three types of alumina have large differences in physical properties. The sand-like alumina has a small bulk density, a large specific surface area, a slightly smaller angle of repose, and a smaller amount of a-Al2O3, and the coarse particles are more and more uniform, and the strength is higher. Flour-like alumina has a large bulk density, a small specific surface area, contains a large amount of a-Al2O3, more fine particles, and poor strength. The physical properties of the intermediate alumina are somewhere in between.
