Abstract
The present invention relates to a large planetary ball mill capable of continuously feeding and discharging materials, which relates to a milling device, particularly to a planetary ball mill technique for continuous production with high flow rate. The planetary ball mill comprises a spindle, a central gear, an idle gear, a milling barrel gear and a milling barrel, wherein the ratio of the effective inner diameter D1 of the barrel body of the milling barrel to the distance R0 between the center axis of the milling barrel and the axis of the spindle is 1: 0.8 to 1.2; the ratio of the gear tooth number Z1 of the milling barrel to the gear tooth number Z2 of the central gear is 1: 0.8 to 1.2. The present invention is suitable for producing continuous feeding and discharging materials with high efficiency and high flow rate. Compared with a common ball mill, the energy can be saved by 30%, and the attrition of alloy steel can be reduced below 0.25 kg/t.
Description
Technical field
The present invention relates to a kind of milling equipment, especially big flow quantity-produced planetary ball mill machine technology.
Background technology
Ball mill is extensive powder processing industry equipment, is widely used in fields such as building materials, electric power, metallurgy, mine, chemical industry.Reach more than 2,000,000,000 tons with the domestic total amount of the powder of its processing, wherein cement is 800,000,000 tons, 9.6 hundred million tons of coal dusts, 0.8 hundred million tons of blast furnace slags, other 2～300,000,000, in national economy, play a part bigger.But because ball mill inefficiency (its pulverize effective power only account for below 10% of grinding machine general power) not only, and to the abrasion height of hard alloy steel, spend the total power consumption of electricity at 600～1,000 hundred million degree in the equal energy consumption 30～50 of ton powder, the abrasion of steel ball, forging and lining board of grinder are on average in about 1,000,000 tons of 0.5kg/t consumption steel alloy, therefore how to improve the ball mill crush efficiency, reduce the steel alloy abrasion, not only meet industrial policy: energy-conservation, saving material can also obtain than considerable economic and social benefit.
Summary of the invention
The object of the present invention is to provide a kind of energy-conservation, material-saving, high efficiency large continuous planetary ball mill.
The present invention includes main shaft, central gear, idle pulley, mill tube gear and mill tube, central gear is fixed on the bearing block of main shaft, and be provided with main shaft is concentric, idle pulley intermeshes with central gear, mill tube gear respectively, the mill tube gear is connected the end of mill tube with one heart, the axis of mill tube is parallel with the axis of main shaft, effective inside diameter D of the cylindrical shell of described mill tube
