Abstract

The invention relates to a grinder. The grinder comprises a feed hopper and a grinding cavity communicated with the feed hopper, wherein the grinding cavity is fixed on a device base, the inside of the grinding cavity is provided with a main shaft, the main shaft is provided with a rotating cutter linked with the main shaft; the grinder also comprises a cavity communicated with the grinding cavity, a screen is arranged between the cavity and the grinding cavity; and the cavity is communicated with a feeding fan through a pipeline, and the pipeline is communicated with a discharge hole. The grinder provided by the invention is used to efficiently grind materials to be grinded such as the waste printed-circuit board of waste electrical appliances and facilitate subsequent recovery and utilization.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a pulverizer. Background technique [0002] With the advent of the information age and the rapid development of the electronics industry, the problem of electronic waste pollution is inevitably in front of us. Circuit boards, which are the core components of various electronic and electrical products, are being discarded more and more. There are many heavy metals and other toxic and harmful substances in waste printed circuit boards, which need to be properly disposed of. If they are discarded directly, it will put a lot of pressure on environmental protection, and it is also a great waste of resources. [0003] At present, there are three main methods of recycling waste circuit boards in China: one is heat treatment, including incineration, cracking, direct smelting, etc., to burn non-metals and extract copper and other precious metals. This method will cause serious damage. Air pollu...
