An excavating bucket for rotating bucket excavators has a trough-shaped bucket having a forward edge formed by a U-shaped bucket lip. The lip has multiple shank holes and a cutting tooth in each shank hole which is removably attached to the lip. There are two sets of corner shank holes which lie on a circular line and receive a corresponding number of corner cutting teeth.

Apr 08, 2018 · Calculating Stockpile Capacity: Once the minimum storage capacities which will assure maximum mill output are known, the appropriate stockpile configuration must be determined. Stockpiles fall into two general categories: conical and elongated. Conical Stockpiles The conical stockpile is the simplest and easiest to analyze. The total stockpile capacity is given by: 3.14 (Tan A)R³ D/3000
