Description

one

The invention relates to devices for wet granulating powdered materials and can be used in the metallurgical industry, in carbon black plants for wet granulation of carbon black.

Purpose Inventing | - improving the economy and improve the quality of the obtained. .

The drawing shows the principle of a jeeJ device for wet granulation of porous materials v

The device consists of a hopper 1 with powdered material for granulation, a screw ribbon auger 2, a shaft 3 with radially laid along a helix with step 4 fingers 4, a cylindrical body 5 with nozzles. 6 for Gpedachi granulating liquid, the outlet 7 And the drive 8.

The device works as follows.

The powdery material in the bunker 1 is screwed with the HbiM screw belt screw 2 into the cylindrical part of the housing 5, where as a result of the screw ribbon insert 2. a constant pitch that exceeds the primary pitch of the screw editor S. Patrusheva

The scientific research institute, formed by radio-mounted fingers 4, the Supplied powdered material is compacted, excluding air leaks through the device into the bunker. Since the powdered material is continuously fed, the compacted layer is destroyed, moving along the jtopnycy 5 with the help of a helix formed by radially arranged fingers 4, SH enters the zone of reflux of the granulating liquid entering through the nozzles 6, which contributes to the creation of germs that enter in a zone with gradually increasing pitch, they are enlarged during rolling and collision between themselves and on the inner walls of the housing 5 and the fingers 4, become denser, become more durable and in the form of ready-made granules blunt vkodnoy pipe. The operation of the device is carried out continuously, the speed of rotation of the shaft is changed by the drive 8, depending on the quality and properties of the powder material.

The application of the proposed unit for wet granulation of powder materials allows to increase the ECONOMY and improve the quality of the obtained granules.
