Coal ball press machine equipment operation - in order to ensure the supply ball machine to work properly, the power supply should not be lower than the dome of the nominal value of the input voltage. When the nominal value of 24VAC, voltage fluctuations should not exceed ± 25%. Dome common operating voltage of 24VAC. Wiring should be stressed that strong, weak separated to avoid strong electrical interference on the weak. Ball machine internal space is limited, so that the strength of electrical coexistence built-in transformer, thus affecting the weak signal. In addition, the built-in transformer cooling will increase the burden, thereby increasing the likelihood of an internal circuit burned. 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 with a certain cohesiveness, (Y values ??may be about 10mm), can also choose a strong adhesion bituminous coal and anthracite by a certain percentage, weakly caking coal, non-caking coal blending (where Y value caking bituminous coal should be 15mm; particle size of coal ball press machine at that lime cheapest, should break 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 ℃), coal is rapidly heated to the softening temperature range (420-450 ℃) 3. Forming: lime pressure ball machine in a pulverized coal 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 stew pot where to buy lime pressure ball machine, 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 type stew blocks, which significantly improved the anti extent broken, hot stew for about 2h or so.
