The roller assembly is an important part of the pellet mill machine, as it exerts pressure and shear forces on the raw materials, transforming them into uniform pellets with a consistent density and size.
The sawtooth-like design of the roller shell helps to prevent slippage between the roller and the raw material. This ensures that the material is compressed evenly, resulting in consistent pellet quality.
● Material: high quality and wear-resistant steel; ● Hardening and tempering process: ensure a maximum durability; ● All our roller shells are finished by skilled staff; ● Roller shell surface hardening will be tested before delivery.
The helical teeth roller shells are mainly used in the production of aquafeeds. This is because corrugated roller shells with closed ends reduce the slippage of material during extrusion and resist damage from hammer blows.
The roller shell is made of X46Cr13, which has stronger hardness and wear resistance.
The teeth are in a Y-shape and evenly distributed on the surface of the roller shell. It enables the materials to be squeezed from the middle to 2 sides, increasing the efficiency.
The surface of the roller shell is welded with tungsten carbide, and the thickness of the tungsten carbide layer reaches 3MM-5MM. After secondary heat treatment, the roller shell has a very strong hardness and wear resistance.
We use the high quality steel to manufacture each pellet mill roller shell with extreme precision for any size and type of pellet mill on the market.
This roller shell has a curved, corrugated surface. The corrugations are evenly distributed on the surface of the roller shell. This enables the material to be balanced and the best discharge effect to be achieved.
HAMMTECH offers high quality customizable 3mm hammer blades for different brands. Different specifications are available to meet your requirement.
