Technical issues that should be paid attention to during the briquetting process

The conventional molding of coal uses thermoplastic binders and relatively good plastic materials. Before the materials enter the feeder of the roll forming machine, the volatiles emitted from the mixed materials are discharged to the horizontal screw conveyor.
The molding of a moderately warm, plastic coal and binder mixture, more precisely, makes it have a certain shape but only makes it dense, so the required unit pressure is relatively low. / cm ,因此使用较小的轴承和使用较宽压辊的成型机也有很大的生产能力。 For example, the pressure used divided by the roll width is described as kN / cm , so a molding machine that uses smaller bearings and a wider press roll also has a large production capacity. Because the quality of forming and briquette improves with the increase of the diameter of the press roll, the roll diameter of the machine is generally larger than 750mm , Usually l 000mm or 1400mm .
加工的。 The shape of the briquettes that shape the briquettes is processed by electrochemical milling (ECM) . This processing technique can arbitrarily choose the shape and size of the stamper. For market reasons, briquette producers usually want to be able to distinguish between their products and their competitors with naked eyes. The shape of the briquette can be changed according to the determined process, for example, using a ball press to produce a complete The beautiful and beautiful briquette can even add marks such as stripes, letters, trademarks, etc. to the product design.
Coal contains impurities, whose composition and quantity depend on the source of the coal. Even if the coal itself is relatively soft, the mixture is already plastic, and the forming pressure is small, these impurities still cause wear. Therefore, the pressure roller is equipped to be more skinning, and the skinning is heat sleeved on the roller core.
个压辊由完全封闭的双输出轴齿轮减速器和有压辊同步装置的齿形偶合器驱动。 The two pressure rollers are driven by a fully enclosed double output shaft gear reducer and a toothed coupling with a pressure roller synchronization device. Even if the material contains a thermoplastic binder and has been plasticized, the material still has relatively good flow performance. Therefore, a gravity feeder with a tongue plate controller or a distribution tray can be used to feed the roll forming machine. The details of the design of the roll forming machine will not be reviewed here.
