The machine is equivalent to the whole of two hammer crushers, which are combined reasonablely. And it has the following features by making both the two sets of rotor working togeter: 1, Both the upper and the lower of the birotor crushing together About the combined two sets of rotors, the broken material crushed by the upper rotor will be finely crushed by the hammer head of the rapid rotated lower rotor again. The inner cavity material will collide and crush rapidly with each other until becoming powder, and then being discharged directly. 2, Without screen grate bottom, the machine canl never be blocked by the high moisture content material. With screen grate bottom, traditional crusher can't be used for the raw material whose moisture content is higher than 8%. And when the raw material's moisture content is higher than 10%, the machine may be seriously blocked, the hammer head can't rotate, the material cann't discharged, and even the motor may be burn out, thus the production wil be influnced seriously. The machine was designed without screen grate bottom and has no strict requirement for the moisture content. It doesn't exist the paste plugging plate problems, let alone fine powder can't be discharged in time and repeat grinding problems. Therefore, it has high crushing efficiency and there is no hammer invalid wear phenomenon. 3, Wear-resisting composite hammer head High alloy wear-resisting composite hammer head. Use the hammer head in combination with the hammer handle, only change the head without changing the handle. 4, Unique transposition gap adjusting technology. There needs no repairing of the hammer head after it was worn, just move its location can realize repeat using. A hammer can be used as three vice hammer. 5, Hydraulic manual start chassis Only one person can easily operate it. It's not only light and fast, but also safe and reliable and easy to repair.
