After 30 years of concentrated research and development, basing on the original two-roll coal ball press machine and small ball press machine, ourcompany has also developed a good four-roll coal ball press machine . Four-roller coal ball press machine working principle isthat the two vice-roll pre-suppress materials in the form of pipeline to lay a solid foundation for the finished ball.Small ball press machine is designed and produced specially for the customers that need small equipment. Small ball machine is a machine used for pressing various powdery materials; it has very wide application and can be used for the pelleting of such materials as coal briquette, lime powdery, mineral powder, aluminium skimmings, active carbon, alumina, bauxite, caustic soda, charcoal, clay, peacoke, coal, cryolite, chemical fertilizer, plastic, limestone, pigment, urea and sylvite. The design purpose of small ball press machine is to reduce dust, control capacity, recycle and reuse and improve the transportation property.Coal briquetting machine is also called coal power ball press machine. It can be divided into cold pressing molding and hot pressing molding, while it gives priority to cold pressing molding. Cold pressing molding ball press machine is divided into two kinds: pressing ball with binder, pressing ball without binder. In general, pressing ball with binder is used. For finishedproducts heroes ball solid foundation. After the main roll for feeding and secondary pressure, the pressure of materialsmultiplied, squeeze the ball more solid product. Reached a multiplier effect. Loose on the local materials, such as coke, ironskin, dust powder effects of sludge and other materials is very obvious.In addition, they are professional jaw crusher supplier, cone crusher manufacture and ball mill suppliers, and stone crusher for sale, etc,.
