The Strength of Compressed Tablets: Part I. The Measurement of Tablet Strength and its Relation to Compression Forces

Abstract

Abstract A motorised single-punch eccentric tablet machine has been fitted with instruments to measure the forces operating during the compression cycle. Apparatus has also been designed to measure the resistance to crushing of the final compact. Sodium chloride was compressed at varying pressures and the relationship between compaction forces, ejection force, strength and voidage investigated.
