SU1671345A1 - Reprocessing method for covers of used batteries - Google Patents

Abstract

The invention relates to the grinding of solid materials, and in particular to methods for processing covers of used batteries (AA) in the field of production of secondary raw materials and waste disposal. The goal is to increase the efficiency of disposal. The flat covers of the IA are strung with metal necks / MG / onto a flexible organ / GO / type of wire and loaded together with the GO into a jaw vibration crusher. After crushing, MG, strung on GO, is separated from crushed ebonite particles of the AI cover by screening. The setting of the crusher is made on the condition of minimizing the deformation of MG and ebonite admixture to MG lead.

Description

The invention relates to the grinding of solid materials, in particular, to methods for processing special materials, mainly covers of used batteries, and may find application in the production of secondary raw materials.

The purpose of the invention is to increase the efficiency of disposal

According to the proposed method, the covers of used batteries, which are known sources of direct electric current, are processed by crushing and subsequent separation. In this case, the differences of the proposed method consist in the fact that the covers string their metal necks onto a flexible organ such as a wire and consistently load with this flexible organ into a vibratory crusher, and during separation separate the threaded necks from the crushed nonmetal particles.

Example Recyclable battery covers are 15 x 100 x 250 mm, each with two lead necks, which must be removed without noticeable admixture of ebonite cover. The caps string the legal entities onto a wire, for example, tie a wire loop into chains of 10-15 pieces. each of them was fed with a belt conveyor to a jaw vibratory crusher. Binders of the crushed throats are separated from crushed ebonite particles on the grate. At the same time, no more than 3% of ebonite remained on the lead, mainly in the impregnated state, which makes it possible to melt the lead and obtain lead castings at an acceptable quality level.

To crush such covers, it is reasonable to use the famous jaw vibratory crushers, in which the crushing cheeks are mounted on torsions. The stiffness of these torsions should be adjusted so that over time, with the closest approach of the cheeks, the distance

60-70% of the height of the neck. The purpose of increasing the efficiency of utilization. The simplicity, the efficiency of the collection of the throat, the caps are strung with metal.

wines and the purity of secondary raw materials are increased by the necks on a flexible organ of the type of economical utilization.5 locks and are consistently loaded with the formula of the invention last into a vibratory crusher, and

The method of processing the covers using separation separates strung necked batteries by crushing particles from crushed metal particles.

Claims (1)

Claim A method of processing the covers of used batteries by crushing and separation, characterized in that, in order to increase the efficiency of utilization, the covers are threaded with metal necks onto a flexible organ such as wires and sequentially loaded with the latter into a vibratory crusher, and during separation, the threaded necks are separated from the crushed < non-metal particles.
