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; coal particle size, should be broken to 3mm, in which fine particles of pulverized coal lmm should control In 85 to 90% is appropriate; water for ease of feeding and metering, coal moisture is best controlled heating in 2-4% 2: Fast thermoforming heating pulverized coal is a key technology in the very short. the time, the pulverized coal at ordinary temperature heating means with vertical tube groups connected in series, dried (120-150 ℃), preheated (122-250 ℃), the coal is rapidly heated to the softening temperature range (420- . 450 ℃) 3. Forming: pulverized coal in a coal briquetting machine, with good adhesion and plasticity was pulverized, homogenized by dimensional temperature, extrusion plasticized, melt molding, can suppress the burning The type of block 4. Thermal stew: coal briquetting machine just has not been able to press out hardened-block, was admitted to the hot pot stew, in the absence of air condition, hot-block in this slow gradual sequence cooled and hardened into a dense texture and hard like coke coal by thermal treatment stew-block gypsum pressure ball machine price, which significantly increased the degree of crushing, hot stew for about 2h or so. Gongyi City Heng Jian Machinery Co., Ltd. production 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 briquetting machine. We would like to provide you with quality service most Full intimate sale, the full technical track allows you to use the rest assured. slag pressure ball machine main structure of the transmission system, main frame, speed reducer, belt conveyor, pre-press equipment, roller sleeve groove ball alignment system, hydraulic system and electric control of several parts. quantitative material, uniformly added while working pressure dome preload device, so that the preload device stable material level, then the pre-pressure by the preload means the material is forced into the spiral of the intermediate rolls the material for pre-compressed and transported to the two pairs of rollers curved slot, two pairs of roller surface evenly distributed identically shaped roller nest, by engaging the drive, so that two pairs of rollers constant, reverse rotation, the delivery to notch materials bite into the tank and forcing compressed gypsum pressure ball machine manufacturers, with roller continues to rotate off the ball in its elasticity and gravity, as the motor rotates continuously rotated periodically pressure roller pressing movement, to achieve mass production. We Fuhua manufacturers gypsum pressure ball machine equipment according to the user appears to pressure the ball machine production process problems with these questions to develop manufacturing equipment Gypsum pressure ball machine to produce products to customer satisfaction true to the customers, to provide customers with first-class service, welcome customers to our factory to buy.
