Grasping the current dynamics and retaining using the trend of time, Zhengzhou referred to as to the energy-saving and environment-friendly in sand maker industry and bought up the courage to abandon the small-size sand maker production with high expense, higher electrical power consumption and small output. Meanwhile, continuously increase the manufacturing ability of large-size devices. The sand maker with very low vitality consumption and emission reduction has grown to be the fantastic equipment and a single massive pattern down the road mining pattern. Performance characteristic of sand maker: This device has the following attributes: stable efficiency, easy processing, uncomplicated composition, uncomplicated servicing, strong capacity, lengthy provider existence of hammer Operating principle of sand maker: When sand maker is doing the job, in the motor driven rotor high-speed rotation, the fabric to the crushing chamber crushing impression crusher and plate hammer around the rotor, after which you can enter the 2nd crushing chamber to smash, and finally through the discharge port. Wear-resisting technological innovation transformation such as hammer, inner lining plate and counter-attack board and technological innovation of energy-saving and high efficient sand maker are 2nd to none, which thoroughly demonstrates the excellent accomplishment and innovation abilities in unbiased innovation. Calcium Grinding Mill with highly effective potential, superior crushing and grinding performance, risk-free and steady operation is the favored selection within the mining, design, highway, railway, metallurgy.
