Problems solved by technology
There are following deficiencies in the manufacture method of this lead powder: 1, hand-cut small lead post, the length of lead post has certain difference; The ratio of lead oxide is the ratio of oxidation degree
For this reason, in order to obtain high-quality lead powder, practitioners in the storage battery industry have conducted a large number of experiments, but have not found a suitable production process for lead powder and equipment for the production of lead particles that match it.

Abstract
The invention discloses a method and device for producing storage battery lead powder. A device for producing the storage battery lead powder is adopted, and operation steps include that an electrolytic lead ingot is placed into a melting pot to be refined, refining temperature is 450-500 DEG C, and the electrolytic lead ingot is completely melt to be liquid lead. The liquid lead is sucked to a lead granule casting machine through a lead pump. The liquid lead is poured through the lead granule casting machine and made into lead granules with the diameter as 15 millimeters and length as 20 millimeters through cooling and demolding, and the lead granules are reserved to be used. The lead granules are placed into a ball mill, the pressure of the ball mill is 26 kilopascal, the temperature is 115 DEG C, and the lead granules are ground. The lead granules with the apparent specific gravity as 1.2-1.6 gram / centimeter 3 are sucked to a lead powder storage bin from the ball mill through a pneumatic concentration method. The lead granules are collected to obtain the storage battery lead powder. Compared with the prior art, the lead granules in the same specification are cast through the lead granule casting machine, a method for producing the lead powder is matched, and oxidizability of lead powder production is guaranteed.
Description
technical field [0001] The invention relates to the technical field of lead-acid battery manufacturing, in particular to a method and a machine for manufacturing lead powder used as lead-acid battery terminal raw materials. Background technique [0002] Lead powder is the main raw material of lead-acid batteries, and its quality directly affects the quality of lead-acid battery products. The production process of lead powder is to melt and cast electrolytic lead into lead pillars. The lead column is added into the lead powder machine to grind into lead powder, and the lead powder, sulfuric acid and various additives are mixed into a paste machine to make a lead paste, and then the lead paste is applied to the grid to make a pole plate. The performance of lead powder directly affects the quality of the plate. Therefore, the manufacturing process of lead powder is a very critical process in the battery production process. A kind of manufacture method of lead powder is arrang...
