Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] like figure 1 As shown in the figure, the vanadium slag granulation device of the present invention includes a feeding system, a pre-pressing and forming system and a screening system. The pre-pressing and forming system includes a pre-pressing hopper 1 and a forming hopper 2. The pre-pressing hopper 1 is provided with a pre-pressing Roller 3 and first edger 4. The feeding system is used to supply material to the pre-pressing hopper 1. The discharge port of the feeding system is facing the gap between the two pressing rollers of the pre-pressing roller machine 3. Edger 4, the first edger 4 breaks up the pressed cake pressed by the pre-pressing roller 3. The forming hopper 2 is provided with a forming press roller 5 and a second edge trimmer 6. The discharge port of the pre-pressing hopper 1 is facing the center line between the two press rollers of the forming...

Abstract

The invention discloses a vanadium slag pelleting device, and relates to the technical field of metallurgy. The problem that vanadium slag pellets prepared by a disc granulator are poor in uniformityand low in pelletizing rate is solved. According to the technical scheme, the vanadium slag pelleting device comprises a feeding system, a pre-pressing forming system and a screening system; the pre-pressing forming system comprises a pre-pressing hopper and a forming hopper; the feeding system is used for supplying materials to the pre-pressing hopper; a pre-pressing roller press and a first edgecutting machine are arranged in the pre-pressing hopper, wherein a discharging opening of the feeding system directly faces a gap between two pressing rollers of the pre-compression roller press, andthe first edge cutting machine is arranged below the pre-compression roller press; a forming pressing roller and a second edge cutting machine are arranged in the forming hopper, wherein a discharging opening of the pre-pressing hopper directly faces a middle line between two pressing rollers of the forming roller press, and the second edge cutting machine is arranged below the forming pressing machine; the screening system is arranged below a discharging opening of the forming hopper; and a finished product bin is connected on a screen of the screening system and a fine powder bin is arranged below the screen. The vanadium slag pelleting device is applicable to vanadium slag pelleting.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a vanadium slag granulation device. Background technique [0002] The existing granulation (also known as pelletizing) machinery is a disc granulator. The disc granulator mainly includes a frame, a disc, a base, a large gear, a transmission part, a scraper frame, a non-power scraper, etc. The granulator disc is lined with high-strength glass fiber reinforced plastic. A plurality of water spray devices are installed above the disc, and the water spray devices are used to spray atomized water. After the vanadium slag, sodium slag, and binder are mixed evenly, they are conveyed to the disc of the disc granulator by a screw. With the rotation of the disc, the material is brought to the top, and then falls to the bottom along the bottom of the disc. At the same time, due to the addition of atomized water, the material gradually forms particles in the process of rotating and falli...
