定义
The roller body is a critical rotating component in pharmaceutical tablet press compression systems, designed to apply uniform pressure to powder blends within die cavities. It features precisely machined surfaces and internal cooling channels to maintain dimensional stability during high-speed tablet production, ensuring consistent tablet weight, hardness, and thickness while minimizing heat generation from friction.
工作原理
The roller body rotates against compression rolls or cams, transmitting mechanical force through its cylindrical surface to compress powder material in dies. Its balanced design and surface finish ensure smooth operation with minimal vibration, while internal temperature control mechanisms prevent thermal expansion that could affect tablet quality.
材料
High-grade alloy steel (typically AISI 4140 or 4340) with surface hardening (HRC 58-62) through nitriding or hard chrome plating. Alternative materials include stainless steel (316L) for corrosive environments or ceramic-coated surfaces for specialized applications.
