The Working Principle of a Compression Load Cell | HBM

Essentially, a compression load cell is a block that is designed to hold a load at one point to measure the compression. While tension load cells measure the pulling force, compression load cells measure a pushing force along a single axis. Generally, a compression load cell is placed beneath the object that needs measuring.

Principals of gold Stamp Mill operations

Principles of Stamp Mill Crushing. The most effective method of crushing is by impact, but as a particle of ore becomes finer it becomes increasingly harder to catch it fairly between two surfaces so that it may be further crushed or comminuted. It is largely because of this that very fine crushing becomes difficult in the stamp battery.
