롤러라고도 합니다. 롤러 쉘펠릿 공장의 주요 작업 부품으로 원료를 다이에 압착하는 롤러 어셈블리의 표면 중 하나입니다. 다이 내부에 장착되어 다양한 종류의 바이오매스 및 가축 및 가금류 펠릿 가공에 적용됩니다.
주로 골판지형(개방형과 폐쇄형)과 보조개형으로 나뉩니다.
1.Material Selection & Preparation
We supply roller shell made of high quality alloy steel, spring steel, and bearing steel. Dimension ranges from 50mm to 1200mm, made from premium-grade materials, high wear resistance bearing steel, alloy steel or carbon steel. (40Cr, 20Crmnti, Gcr15/60SiMn), featuring with high wearing resistance, hardness, long service life and good pelleting performance together with our dies.
Prepare blanks via casting or forging, ensure that the internal structure is dense and defect-free.
2.Precision Machining
Finishing Precision Turning: Finishing dimensions to drawing requirements to ensure tolerances (such as IT6-IT7). Drilling/keyway processing: mounting holes, lubrication holes or transmission keyways.
3. 열처리
Carburizing heat treatment,Quenching & tempering to achieve surface hardness (HRC 58-62). hardening depth 6-8mm, uniform hardness and long service life.
4. Quality Inspection and dimension detection
Dimensional checks: caliper, three-coordinate measurement. Hardness tests : Rockwell hardness meter. Flaw detection: Ultrasonic or magnetic powder flaw detection to check internal cracks.
5. Finished rollers and package
