Detailed Product Description: | Previously, China's metallurgical industry, lime powder mostly been abandoned or changed into other uses, resulting in a tremendous waste of resources, along with the increasingly tense energy resources, the use of lime powder metallurgy industry, more and more people's attention. Since 2002 related to the metallurgical industry through research institutes, to solve this problem, namely the use of high-pressure powder ball press machine, the powder is pressed into a ball out of the kiln blocks for smelting use at present, some steel mills abroad and China's Baoshan Iron and Steel, Anshan Iron and ready to use. Specific process is as follows: After screening lime kiln lime pressure ball machine, less than 3mm into the high-pressure powder powder ball press machine pressure the ball, the ball block specifications for 35mm × 25mm × 15mm (length × width × thickness), also in accordance with need customized party, get the ball block bulk density 1.9-2.2g / cm3, strength and bulk lime quite fall. After the pressure of the ball after screening, passing the ball into the finished product warehouse block use for smelting. Ball press machine equipment thermoforming process, is prepared by a coal, heating, molding, hot stew composed of four parts. 1. Preparation of coal: Coal on coal quality is concerned, you can choose suitable for hot-pressing process of a single species of bituminous coal has a cohesiveness that house lime pressure ball machine cheapest, (Y value at about 10mm may be), Strong adhesion can also choose a certain percentage of bituminous coal and anthracite, weakly caking coal, non-caking coal blending (where Y value caking bituminous coal should be 15mm; coal particle size, should be broken to 3mm, which lmm The fine particles of coal, should be controlled at 85 ~ 90% is appropriate; the water is easy to feed and metering, coal moisture is best controlled heating in 2-4% 2: rapid heating pulverized coal is hot. The key lime molding technology that house pressure ball machine service best, in a very short period of time, the pulverized coal at room temperature using a heating device upright tube several groups in series, dried (120-150 ℃), preheated (122 -250 ℃) lime pressure ball machine, coal is rapidly heated to the softening temperature range (420-450 ℃) 3. Forming: pulverized coal in coal briquetting machine, with good adhesion and plasticity was pulverized By dimensional temperature homogenization, extrusion plasticized, melt molding, can suppress the hot-block 4. Thermal stew: coal briquetting machine just has not been able to press out hardened-block, sent into the hot pot stew, in the absence of air condition, hot-block sequence in this slow gradually cooled and hardened into a dense texture like coke and hard coal by thermal treatment stew-type blocks, which significantly increased the degree of crushing, hot stew for about 2h or so. Gongyi City Heng Machinery Co., Ltd. specializes in producing built pressure ball machine, briquette press the ball machine, powder ball press machine, gypsum pressure ball machine, coke breeze pressure ball machine, slag pressure ball machine, coal powder ball press machine.
