The artificial sand maker mainly includes horizontal hammer sand maker, vertical shaft hammer sand maker, vertical shaft impact sand maker and roller sand maker.The horizontal VSI crusher can be divided into split hammer headstructure and monolithic hammer head structure. Hammer head adopts highstrength wear resistant material; it has a long life and convenientreplacement.
Vertical shaft hammer sand maker is mainly used for second or thirdstage crushing; it can handle various coarse, medium and fine materials,such as granite, limestone, concrete, etc. whose side length within500mm and compressive strength not more than 350MPa, widely used inhydroelectricity, highway, artificial aggregate and crushing industry.
Advantages: the device is without bottom screen, so there is noclogging. Additionally, hammerhead adopts monolithic structure, can bedirectly connected to the rotor.
Vertical shaft impact sand maker
In accordance with the structure of the rotor, vertical shaft impactsand maker can be divided into: open rotor structure and the closed-endrotor structure.The rotor of the former type appears open structure; having fallen intothe rotor, materials are crushed by hammer; and the rotor of the latertype appears cage layout; materials are thrown at a high speed out afterfalling into the closed-end rotor.Roller sand maker is usually used in sand making field of smallproduction capacity; because of the relatively poor reliability, highfailure rate and difficult repair and maintenance, it is avoid to beingused to handle materials with a certain hardness and high abrasion.
