Counterattack efficient sand making machine is absorbing domestic and foreign advanced technology, combined with the specific mining conditions of the relevant domestic industry developed the latest generation of high efficiency sand making, for a variety of medium hardness solid material crushing; widely used in granite, basalt, limestone river gravel, cement clinker, quartz, iron ore, bauxite and other minerals in the fine crusher. The mechanism is also used for artificial sand, highway, railway, water conservancy, airport, construction, cement, refractory, metallurgical and other industries to produce high-quality stone. Counterattack efficient sand making machine has a small particle size material grain type uniform, large production capacity, hammerhead long life, supporting small power, change the tertiary crusher for secondary crushing, process simplification, simple structure, easy maintenance and smooth running characteristics . Counter-Efficient Sand Henan hong Heavy Industry design and development of a new generation of energy-saving sand making performance characteristics of the equipment performance is stable and reliable, easy maintenance, small size, light weight, easy to replace parts, easy to move, process simplification, simple structure change tertiary crusher for secondary crushing, large capacity, high yield, hammerhead long service life, environmental protection and energy saving, suitable for crushing granite, basalt, quartz, carborundum, a variety of ores, bauxite, river gravel and other materials. Working principle of the machinery for the continuous operation equipment, work in the motor driven rotor high-speed rotation of the material into the first crushing chamber crushing rotor plate hammer impact crusher, and then enter the second crushing chamber crushing last the discharge port.
