1.Brief description: 2DSKP/2PLF serial double roller crusher is our self-developed crushing equipment that is widely used in the industry of coal, coke, metallurgy, chemicals, building and other industries. Characteristic: Complete case structure will solve the problems of unstable bearing position and keep the crushing space closed to ensure the working environment clean. The crushing teeth are casting by high anti-abrasion alloy(HRC 45-55, impact toughness 38Kg·m/cm2) that is with characters of high strength, high toughness and high wear-resistance. The service life is 2-3 times longer than normal crushing teeth. Various structures of crushing teeth: there are movable tooth structure, cutting sleeve structure, ring structure, plate structure and whole roll structure, which can be customized according to the actual situation. There are kinds of manners to adjust the product size that are eccentric cup, leading screw and hydraulic which will ensure the outlet size. The tooth layout are optimized; there are various types such as single screw type, double screw type, multi screw type and straight type; this will make sure high crushing rate. Coupling and belt wheel adopts fast disassemble manner that is expansion+key which will make sure enough strength and easy disassembling. The application of advanced damping structure, coupling absorbing temporary impact and each protection for mechanic and electric will improve the liability of crusher and decrease the troubles during operation. There are various walking ways that is fix type, leading screw type, hydraulic type and electric type, which is easy for maintenance. Be equipped with advanced protection device for overload and stalling, intelligent control, lubrication system, easy and liable operation.
