Granulators

Granulation turns fine powders into larger, uniform granules. This helps the material flow better and compress into tablets more easily. In dry granulation, powders are compacted using rollers or presses, then milled into granules. It's a key step for making consistent, high-quality tablets—especially when the product can't handle heat or moisture.

Granules flow better and compress more evenly than loose powder. This helps make tablets that are uniform in weight, strength, and quality. Granules also reduce dust and improve handling during production.

The three main types are:

• Wet granulation – Uses a liquid binder to form granules. Requires a drying step.

• Dry granulation – Uses pressure to compact powder into granules. No liquid or drying needed.

• Direct compression – No granulation. The powder mix is compressed directly into tablets.

It depends on your product and process. Wet granulation is common, but it requires drying and can be time-consuming. Dry granulation is often better for heat- or moisture-sensitive materials. It’s faster, uses less equipment, and doesn’t require drying. If you're looking for an efficient, no-water method, dry granulation is a good choice.

A granulator forms larger granules from powder to improve flow and compression. A milling machine breaks down material into smaller particles or controls particle size after granulation. In tablet manufacturing, granulators build up size, while mills reduce or even it out. Both are often used together for consistent tablet quality.
