Allowable Vibration Value Of Coal Crusher

How a Roller Crusher Crush Coal Gangue | Fote Machinery

Mar 08, 2021· When crushing coal gangue, it should go through three processes of "coarse-middle-fine crushing". Roll crusher. 2. Grinding and maintaining frequently. The surface of the roll crusher is easily worn to grooves and makes the gap between the rolls larger, thereby reducing the crushing effect.

Vibration Test and Shock Absorption of Coal Crusher

However, the maximum vertical vibration displacement of the coal crusher in the Linyou power plant was 219.39 μ m, which exceeded the allowable value and did not meet the vibration safety requirements. The measurement point on the floor was near the coal crusher to determine the maximum vibration response of the floor slab near the coal crusher.

Vibration and Distance - Vibrationdamage.com

Mar 29, 2021· The higher the value of b, the more the vibration dissipates with increasing distance. The division of the distance by the square root of the charge weight is usually referred to as " square root scaling " in the scientific literature, since its goal is to place a series of blasts with different amounts of explosive on the same source energy basis.
