Pressing balling machine

Abstract

The invention discloses a pressing balling machine. The pressing balling machine comprises a material mixing system, a feeding system, a first conveying system, a first pressing balling system, a second conveying system, a second pressing balling system and a transfer system. The first pressing balling system comprises a first press roll and a second press roll, wherein the first press roll and the second press roll are arranged side by side in a spaced manner. The first press roll and the second press roll are rotatable. Both the peripheral surface of the first press roll and the peripheral surface of the second press roll are smooth surfaces. Materials are suitable for penetrating through the part between the first press roll and the second press roll. The second pressing balling systemis connected with the second conveying system. The second pressing balling system comprises a third press roll and a fourth press roll, wherein the third press roll and the fourth press roll are arranged side by side in a spaced manner. The third press roll and the fourth press roll are rotatable. A plurality of spaced ball sockets are formed in the peripheral surface of the third press roll and the peripheral surface of the fourth press roll oppositely. Materials are suitable for penetrating through the part between the third press roll and the fourth press roll. According to the pressing balling machine, the compactibility of pressed balls can be guaranteed, the strength of pressed balls is improved, and the of balling of the pressed balls is increased.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a ball pressing machine. Background technique [0002] In metallurgy, mining, coal, refractory materials, chemical industry, building materials and other industries, it is usually necessary to treat some materials such as iron concentrate powder, chromite ore powder, copper concentrate powder, copper slag, chromium ore powder, manganese ore powder, laterite nickel ore, Lead and zinc waste, bauxite, red mud, non-ferrous metal powder, quicklime powder, dolomite powder, iron-containing powder in steel mills, etc. are used to make pellets for smelting and direct reduction. The method is to mix the above-mentioned powder with a binding agent and a reducing agent, and go through production processes such as mixing, pressing, drying and the like. The key process is forming. In order to increase the output and ensure the strength of the pellets, it is now manufactured by a double-...

AI Technical Summary

Problems solved by technology

[0003] In the process of studying the briquettes of the briquetting machine, it was found that: due to the binder in the material, the air is enclosed in the pellets during the briquetting process, which affects the compactness of the pellets. In order to compact the pellets, it is necessary to Using high pressure to press the ball, despite this, the ball forming rate is still quite low

For different materials due to their different properties, it is necessary to repeatedly adjust various parameters of the pellet machine, resulting in extremely unstable performance parameters of the pressed pellets, and it is difficult to ensure the strength of the pellets

Especially the red mud material has a particularly high requirement for moisture. If the moisture is too high, it will easily form mud and roll sticking phenomenon, and it is difficult to clean, reducing the operation rate. If the moisture is too low, it will be difficult to form pellets. in industrial production
