Optimal Tablet Press Operation: Machine versus Granulation

A tablet press is one of the most complex machines used in the manufacturing environment. Clearly defining the basic principles in tablet press operation is essential to having a successful run. Learning key factors can help to avoid the many obstacles that can interrupt a successful run. Worldwide, more than 18 different companies make tablet presses. All tablet presses operate in the same basic way with only a few exceptions. This fact allowed the industry to define and create a standard for tablet press machines and tablet press tooling, which was published in the Tablet Specification Manual (TSM) by the American Pharmaceutical Association. The TSM can be acquired through any tooling or tablet press supplier. This article discusses how tblet press performance can be optimized by clearly distinguishing between granulation and machine issues; focusing on the importance of flow, compression, and ejection; and performing the necessary maintenance and quality control checks.
