Hydraulic tablet press and rotary tablet press are two different types of machines used in pharmaceutical, food and other industries to produce differen kinds of shapes and sizes of tablets. They have big difference in how they work. The following are the main differences between the working principles of hydraulic tablet presses and rotary tablet presses:

Hydraulic tablet presses use hydraulic pressure to compress powders or granules into differen kinds of shapes and sizes of tablets.

Compressive force is applied vertically by a hydraulic piston or cylinder that moves up and down to form tablets into differen kinds of shapes and sizes in the mold cavity. Hydraulic presses are typically used in research and development, small-scale production, or to produce tablets with complex shapes and designs.

Rotary tablet press machinery operate based on rotational motion.They have a rotating turret with multiple punches and dies that move in a circular motion.

The powder or granules are fed into the mold and compression occurs as the turret rotates, forming differen kinds of shapes and sizes tablets. Rotary tablet presses are suitable for high-volume production and are more commonly used for large-scale tablet production.

The choice between a hydraulic tablet press and a rotary tablet machine depends on the specific requirements of tablet production. Hydraulic presses are ideal for small batches, specialized tablets, and research purposes, while rotary presses are the preferred option for large-scale production of standardized tablets with high efficiency and productivity.
