The aim of this study was to compare the tableting process of tablets on Fette 2090 and Fette 3090. The Fette 2090i and Fette 3090i are both multi-station tablet presses. Тhe significant difference between them is that the 3090i as a new generation tablet press generates a larger number of tablets in a shorter time because it is a double rotary press, unlike the 2090 which is a single rotary press. Fette 3090i has double-sided production, two filling devices, two pre-compression and main compression stations and two tablet discharges. Fette 2090i as s single rotary press has one sided production, one filling device, one pre-compression and main compression station and one tablet discharge. Tablets were produced by direct compression or DC as it is known in the industry. DC is the mixing of raw materials into a uniform blend, which are then compressed into a final tablet. In recent years direct compression has become extremely popular in the tableting industry. This is due in part to its low cost and simplicity. The main goal of this research was to determine how the speed of tableting affects the quality of the produced tablets. Depending on the formulation the tablets can be produced with lower or higher tableting speed. In this case, tablets are produced with a speed of 100 000 pcs/h on Fette 2090i and with a speed of 300 000 pcs/h on Fette 3090i.
