    High Reduction Ratio Crushing In Conical Gyratory Crushers

    Calculation of reduction ratio in crushing [image (135 5 3)] Crushing Equipment The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant (e.g. blasting pattern and mining method) and others which are downstream of the crushing plant (e.g. mill and grinding circuit selection).Dec 06, 2014 Rankin’s formula is also known as Rankin Gordon Formula. It gives the ultimate load that column can bear before failure. If column is short, calculated load will be known as crushing load. And load will be buckling or crippling load, in case of long column. This formula only gives the ultimate load, but columns are design on safe load.

    Already well known for rugged construction, low profile, high reduction ratio, and economical cost, Williams Dust Tight Ash Single Roll Crushers also have easy access to the rotor for maintenance. These dust tight roll crushers are perfect for applications such as crushing ash, limestone, coal, or glass.A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6 1 reduction ratio. Thus, with a 3⁄4” closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. Reduction ratios of 8 1 may be possible in certain coarse crushing.
