Abstract

The invention relates to a lead pig grinding and granulating machine which comprises a stand (12) and a working platform (1). The lead pig grinding and granulating machine is characterized in that two counter-roll matching grinding rollers (3), two counter-roll matching longitudinal-cutting rollers (4) and two counter-roll matching cross-cutting rollers (6) are sequentially arranged on a stand (12) at a certain interval, wherein the surface of each longitudinal-cutting roller (4) is uniformly provided with one group of longitudinal cutting blades (5) around the circumference along the axial direction, and the surface of each cross-cutting roller (6) is uniformly provided with cross-cutting blades (7) parallel to the axial direction along the circumference. The invention has the advantages that the traditional process of counter-roll extruding and granulating after slicing a lead pig is discarded, and advanced processes and devices of firstly grinding, then rolling and stripping, then crossly cutting and granulating are adopted. Compared with the prior art, the lead pig grinding and granulating machine has the advantages of high granulating efficiency, high material utilization rate, long service life, low manufacture cost and the like.

Description

technical field

[0001] The invention relates to a mechanical device for cutting soft metal into flakes in a cold state, in particular to a lead ingot rolling granulator used in lead ingot granulation equipment in the lead-acid storage battery industry. Background technique

[0002] At present, in the lead-acid battery manufacturing industry, the lead powder machine for producing lead powder needs to use about 50g of lead pellets as raw materials. The traditional method is to melt lead ingots (each ingot weighing 45kg) in a lead melting pot and separate them into lead pellets, which not only wastes a lot of energy, consumes lead materials, but also seriously pollutes the environment. In order to fundamentally solve these problems, a new process of directly dividing lead ingots into lead flakes in a cold state and producing lead pellets from lead flakes has emerged. In this process, after the lead ingot is divided into lead flakes in a cold state, the lead flake double-roll g...
