Sand making machine can be divided into four main categories:
Include :horizontal hammer type crusher, vertical shaft impact crusher, roller type sand making machine, vertical shaft hammer crusher.
(1) Horizontal hammer type crusher : Horizontal hammer crusher sand making machine is mainly PX efficient fine crusher ( split hammerhead structure ) and hit the sand machine ( integral type hammerhead structure ).Efficient fine crusher hammerhead and a hammer handle are split structures, hammerhead adopts high-strength wear-resistant material, long service life of hammer. Hammer replacement more convenient. The bottom has a screen plate structure, can achieve effective frayed, improves the efficiency of sand. Play the hammer pressure-blasting machine hammer is an integral structure, directly through the rod connected to the rotor. Due to this structure, the hammer in the crushing process will produce a larger force, so the head materials of low hardness, so the hammer abrasion resistance is weak. Daring play sand machine has the advantages of simple structure, low price, small work place is an option.
(2) Vertical shaft Pelton Sand : Vertical shaft Pelton Sand according to rotor structure is divided into: the open rotor structure and a closed type rotor structure. Closed type rotor structure, the rotor into the cage is layout, material from the top into the closed after the rotor, is high throw. Open type rotor structure, the rotor is open structure, material into the rotor, by throwing hammer hit.
(3) Roller type sand making machine : In the small capacity of the sand fields, using roller crusher sand making machine for use, are also part of the application. But the roller type sand making machine used in the long termIn the process of poor reliability, fault rate is higher, the repair and maintenance more difficult. Therefore, to have certain hardness and abrasion resistance of high material, to avoid the use of roller type sand making machine.
