Black carbon crushing machine

Abstract

The invention relates to a carbon black crusher which is characterized in that a frame, a main powdering chamber and a secondary powdering chamber are included, wherein, the main powdering chamber and the secondary powdering chamber are arranged on the frame sequentially; the main powdering chamber is divided into a main powdering cavity and a filtration cavity by a main screen which is vertically arranged and a breathable layer which is vertically arranged at the periphery of the main screen; a disintegrated powder mixer is vertically arranged in the main powdering cavity; a granular carbon black inlet and a granular carbon black outlet are formed on the main powdering cavity; the material outlet of the filtration cavity communicates with the secondary powdering chamber; the secondary powdering chamber is also divided into a secondary powdering cavity and a secondary filtration cavity by a secondary screen which is horizontally arranged and an outer casing baffle plate which is arranged at the periphery of the secondary screen; a secondary disintegrated powder mixer is horizontally arranged in the secondary powdering cavity; a material discharging pipe is arranged on the secondary powdering cavity; through a blower, carbon black is fed into a bag filter for filtering and collecting; and the filtered and collected carbon black enters a storage hopper. The carbon black product ground and crushed by the crusher of the invention has the advantages that the particle size is small, the particle size distribution is narrow, the surface of the carbon black has a lot of oxygen-containing functional groups, and the dispersion property and the flow property of the carbon black are good.

Description

Technical field: [0001] The invention belongs to the production field of carbon black, and more specifically relates to a special pulverizer for carbon black such as acetylene carbon black. Background technique: [0002] Carbon black is a kind of amorphous carbon, which is a light, loose and extremely fine black powder with a very large specific surface area ranging from 10-3000m2 / g. It is an organic matter (natural gas, coal tar, anthracene oil, fuel oil, calcium carbide, etc.) The product obtained by incomplete combustion or thermal decomposition under the condition of insufficient air, which is widely used in rubber and plastic products, paint, ink, leather, coating, color masterbatch, plastic, footwear, batteries and conductive products, static electricity Copying and other industries. However, the carbon black products currently produced have a medium particle size (PSL-301 carbon black particle size is smaller), a narrow particle size distribution, and poor dispersibi...
