Problems solved by technology

The current known dry granulation equipment uses a screw conveyor that runs through the granulation drum for both the powder entry and the reflux of the granules. It is difficult to adjust the reflux flow of the granules and the granulation efficiency is poor due to inaccuracy, and the scale of the equipment cannot be enlarged. The problem of low grain production capacity

Embodiment Construction

[0007] Figure 1 shows a schematic diagram of the invention. The dry granulation system of the present invention includes a granulator, a hoist, a screening machine, a granulator, a bag filter, and a powder silo, and the granulator is composed of a granulation drum, a feed end, a discharge end, and a screw conveyor. , the specific implementation is as follows:

[0008] The carbon black powder enters the powder silo 9 from the upstream process, and the material in the powder silo 9 enters the screw conveyor 4, and is pushed by the screw conveyor 4 to the inside of the granulation drum 1, and then passes through the granulation drum 1 from the discharge end 3 The discharge port on the top enters the hoist 5, and enters the screening machine 6 after being lifted. After screening, the unqualified materials are returned to the powder bin 9, and the qualified pellets enter the pellet bin 7, and a part of the materials in the pellet bin 7 are automatically fed. The feed port on the e...

Abstract

The invention discloses a dry granulation system, and particularly relates to dry granulation of carbon black. The dry granulation system comprises a granulator, an elevator, a screening machine, a granule bin, a bag filter and a powder bin; the granulator is composed of a granulation roller, a feeding end, a discharging end and a spiral conveyer, and the dry granulation system has the beneficial effects that the productivity is increased, the reflux quantity of granules is accurately controlled, the granulation efficiency is improved, and the quality of finished products is improved.

Description

technical field [0001] The present invention relates to a dry granulation system, especially carbon black dry granulation, including a granulator, a hoist, a screening machine, a grain bin, a bag filter, and a powder bin. The granulator consists of a granulation drum, It is composed of feed end, discharge end and screw conveyor. Background technique [0002] Due to its low bulk density, easy flying, and poor fluidity, powdery carbon black is not easy to store, transport and use. Therefore, it is necessary to make powdery carbon black into granular carbon black, increase the bulk density by nearly 10 times, solve the problem of flying and significantly improve fluidity. There are dry method and wet method for making powdery carbon black into granular carbon black. Dry granulation has the advantages of low energy consumption and high product quality. Dry granulation is to complete granulation without adding auxiliary granulation agent. The granulation process needs to add gr...
