jaw crusher VS cone crusher

1. The feed size of the jaw crusher is ≤1200mm, the treatment capacity is 15-500 tons/hour, and the compressive strength is 320Mpa. The cone crusher has a feed size of 65-300 mm, a production capacity of 12-1000 t/h, and a compressive strength of 300 MPa. By comparison, the jaw crusher can meet t... Read More

What is vibrating screen machine?

   The vibrating screen works by reciprocating rotary vibration generated by vibrator excitation. The upper rotating weight of the vibrator causes a plane to oscillate the surface of the screen, while the lower rotating weight causes the screen surface to produce a cone-shaped rotating vibration....
