Efficient crushing machine mainly by: the back plate means, side liner, back plate, front liner means, sieve means and the upper and lower shell composition efficient compound crusher advantages and characteristics of the hopper in order to enter the cavity, a drop in high-speed rotation combating the hammer, the hammer and the back plate through action between Gansu efficient Sand, material preliminary crushed in a hammer area. After the material many times by high-frequency repetitive hammering and back, fall on the separator to form a deposited, generating Gansu efficient Sand slipped and landed on the lower portion of the rotor rotation tell thrown trays, has been thrown into the high-speed counter plate into the collision, fall and via a mobile hammer mandatory counterattack, crushing, grinding. Therefore, the material through its own weight during multiple complex whereabouts crushed, erosion grinding. In order to achieve ultra-fine effect. Our researchers after years of research, reference works crushing machine at home and abroad, and according to user feedback of information, combined with its advantages, developed a new energy-efficient heavy third generation sand-dryer. The typical use is to adapt the current (manual system sand and gravel) industry Gansu efficient Sand, at present, by the practice of heavy sand (third-generation dual-gravel Sand) overall performance is superior to the crusher, rod mill Sand, really through impact Sand, and cone crusher and soft hammer crusher. The device is suitable mechanism artificial stone made, Sunaba, highway, rail, water, construction, cement, refractories, metallurgy, glass sand and other industries producing quality stone's preferred device. Work, driven by the motor Gansu efficient Sand, high-speed rotation of the rotor, the material into the first crushing chamber and the rotor plate hammer impact crusher, and then smash into the second crushing chamber. In the crushing process, not only the formation of the impact crusher plate hammer and lining material between, and also completed a hammer between each board and stone crushing cavity performed at stone shaping. Finally discharged from the discharge port. Sand making equipment, Huaying Heavy Industries (online consultation), provided by the Zhengzhou Gansu Sand Mine Equipment Co., Huaying. Huaying Zhengzhou Mining Equipment Co. (www.huayingjx.com) is a leader in Zhengzhou, crushing grinding equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Heavy in Huaying leadership with the staff warmly welcome all inquiries negotiations to create a better future Huaying Heavy.
