Roll presses are essential machines used in various industries to compress materials into desired shapes or forms.
Whether you're dealing with powders, raw materials, or large workpieces, roll presses can handle it all.
The process involves several key components and steps that ensure the final product is of high quality and uniformity.
How does a roll press work? 5 Key Components Explained
1. Pre-Compression and Main Compression Rollers
Pre-compression rollers are the first step in the tablet-making process.
Their main function is to remove air from the die cavity, ensuring a denser final product.
Main compression rollers then apply the final force to form the tablets.
These rollers maintain a steady pressure to ensure uniformity and quality in the final product.
2. Ejection Cam and Take-Off Blade
After compression, the ejection cam comes into play.
It pushes the bottom punches upwards, ejecting the finished tablets from the die cavity.
The take-off blade then guides these tablets into the discharge chute.
This chute directs the tablets out of the press for collection.
3. Roll Compaction and Powder Extrusion
Roll compaction involves feeding powders into a gap between two rotating rolls.
These powders are compacted into a sheet and then sintered in a furnace.
This process can be repeated for enhanced material properties.
Powder extrusion, on the other hand, involves placing powders in a sealed container and extruding it to form parts with specific dimensions.
4. Two Roll Mill
In a two roll mill setup, raw materials and additives are placed between two rolls that rotate.
These rolls draw the materials into the roll gap, where they undergo intensive squeezing and shearing.
This increases the contact area and disperses the components evenly.
The process continues until the desired material state is achieved.
5. Eccentric Shaft and Pneumatic Control
The eccentric shaft in roll pressing systems allows for precise control of the gap between the rolls.
This shaft multiplies the applied force to achieve high pressures.
A pneumatic step motor adjusts the angle of the eccentric shaft, enabling fine adjustments in the gap setting.
This ensures accurate and consistent compression.
