Circular mold granulator

Abstract

The invention discloses a circular mold granulator which comprises a rack and a forming roller. Forming holes penetrating through the inside and the outside are densely distributed in the forming roller. A compression roller spindle driven by power of a compression roller driving device is installed in the forming roller. A compression roller set matched with the forming roller to conduct ceramsite forming is installed on the compression roller spindle. A scraping knife capable of being attached to the outer wall of the forming roller is connected to the rack. The forming roller and the compression roller spindle rotate reversely. An annular material inlet is formed in the front side of the forming roller. A feeding barrel located on one side of the forming roller is installed on the rack, a feeding opening is formed in the feeding barrel, and a feeding screw is installed in the feeding barrel. A main shaft of the feeding screw and the compression roller spindle are coaxially arranged and connected through a coupler. A conical material guiding barrel is installed between the discharging end of the feeding barrel and the material inlet, the material guiding barrel is fixedly connected with the outer wall of the forming roller, and the material guiding barrel and the feeding barrel are connected in a rotating and sealing mode. The circular mold granulator has the advantages that the ceramsite forming quality is high, the continuous production efficiency is high, and the ceramsite forming quality is improved.

Description

technical field [0001] The invention relates to a granulator industry, in particular to a ring die granulator. Background technique [0002] Ceramsite is widely used as aggregate in the construction and building materials industry due to its advantages such as reasonable particle size distribution, small bulk density, low thermal conductivity, low water absorption, high refractoriness, good thermal insulation effect, and acid corrosion resistance. As one of the important raw materials of lightweight aggregate, the molding process of ceramsite is as follows. After the raw materials (construction impurities, stone powder, additives, etc.) are batched, they are stirred and mixed by a mixer, and then granulated by a granulator. . After the granulation is completed, it needs to be dried and cooled to finally form a finished product. [0003] After the raw materials have been batched and stirred, they need to be granulated by a granulator. Existing granulators mainly include tw...

Problems solved by technology

The disadvantage of the top feeding structure is that the top feeding is easy to cause the material to concentrate on the top or fall to the bottom, the material enters unevenly, and some of the pressure rollers in the ring cloth may not work (or the extrusion amount is not enough) ), that is, some mesh holes on the outer ring cylinder will not produce particles, so the production efficiency is low
