    Gyratory Crusher - an overview | ScienceDirect Topics

    The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are

    Dec 26, 2019 Erosion = XC 3. C is the velocity of the particle. X is a coefficient based on the liquid. being pumped. The velocity of the particle is directly associated to the tip speed of the impeller (Image 1). Lowering the tip speed of a machine has a significant impact on particle velocity and, thus, the erosive energy. Equation 2:

The washing machine will have a default spin speed for the type of clothes (and program you have chosen). Wool will require a slower spin speed (around 600-800rpm), synthetic will need around 800-1000 rpm and cotton will need 900-1400rpm

    Basics in Centrifugation. Centrifugation is a technique that helps to separate mixtures by applying centrifugal force. A centrifuge is a device, generally driven by an electric motor, that puts an object, e.g., a rotor, in a rotational movement around a fixed axis. A centrifuge works by using the principle of sedimentation: Under the influence
