Chromium Ore Powder Briquetting

The chromium ore powder briquetting machine mainly suppresses various iron powder, mineral powder, iron oxide scale, steel slag, refractory materials, etc. Any material that needs to be smelted with powder needs a mineral powder pressure ball machine.

In the past, most of the lime powder in China’s metallurgical industry was abandoned or changed to other uses, resulting in great waste of resources. With the increasingly tight resources and energy, the utilization of lime powder in the metallurgical industry has received more and more attention.

Mineral powder generally refers to the powder obtained after crushing the mined ore. For example, iron ore powder refers to the magnetic separation of different types of iron ore, such as limonite and magnetite. For iron ore with different iron content, the iron content of the mineral powder is 60-68%, and the super concentrate powder is 70-72%, while the iron powder refers to the higher iron content than the ore powder, which is processed by different processing methods such as reduction. , water or gas atomization method, mechanical pulverization method, electrolysis method, molten salt decomposition method, evaporative condensation method, etc., obtain high grade, and reach the granular iron powder with the required particle size.

After the kiln lime is screened, the powder of less than 3mm enters the pressure ball of the high-pressure powder ball press. The ball size is 35mm*25mm*15mm (length*width*thickness), and can also be customized according to the requirements of the purchaser to obtain the volume of the ball. The density is 1.9-2.2g/cm3, and the drop strength is equivalent to that of bulk lime. After the ball is pressed, the qualified ball blocks enter the finished product warehouse for smelting.

The working principle is that the powder containing a certain amount of water enters a set of concentric inner and outer cylinders and is transported by wheel to the annularly distributed die hole groove, and the design is rotated together with the main shaft, and the outer circle is provided with a spiral piece; the outer cylinder is The stationary one is also provided with a spiral blade on the outer side, and the ground rotation direction is opposite to the outer circle of the inner cylinder. The forage is extruded on the side of the die hole that is subjected to the eccentric pressure plate, and is formed by extrusion from the radial direction. The length of the extruded block is controlled by an adjustable tapered steering ring disposed at the exit of the die. During the extrusion process, the heat generated by the friction specifically increases the temperature of the stamper to about 82 °C.
