Now we have the roller shells of different shapes, such as:close-end grooved roller shell, honeycombed roller shell, drum-hole groove roller, open-end grooved roller shell, deflective-grooved roller shell etc.
■ All roller-shells are manufactured using high carbom steels.
■ All roller-shells are surface-hardened up to 58-62HRC
■ Hardening depth is 6-7mm for C50 steel.
■ The heat treatment is characterized by uniform hardening and hardening depth to ensure maximum durabilty.
■ All our products are finished by skilled staff.
■ Roller-shell surface hardening is tested before delievery to ensure premium quality.
Open-end grooved drum roller shell characteristics:
■ Shape：open-end grooved drum corrugated
■ Material: Alloy steel, spring steel and bearing steel.
■ Special thermal treatment ensures better wear resisting, and pelletizing performance.
■ Long working life
