Fish Scale Shaped Roller Shell
Fish scale shaped roller shells are precision-engineered components for pellet mills, designed with a textured, scalloped surface to enhance material grip and compression efficiency during pellet formation. The shell is the outer surface of the roller assembly that presses raw feedstock against a rotating die. The listing specifies material options including C50, 20MnCr5, and 100Cr6 steels, with hardness ranging from HRC 58 to 62. These shells are custom fabricated to match die dimensions and are used in feed, biomass, and fuel pellet production systems.
The fish scale pattern consists of evenly spaced, angular grooves that improve feed flow and reduce slippage compared to smooth or dimpled rollers. The material choice determines wear resistance and service life - 100Cr6 offers high chromium content for abrasion resistance, while 20MnCr5 provides good toughness under high stress. Surface finish is typically ground to a tolerance of ±0.02 mm. The shell is not coated but hardened through heat treatment, with no surface plating mentioned in the listing.
These roller shells are purchased by manufacturers of animal feed, wood pellets, and biofuel plants requiring high-wear components for continuous operation. Buyers typically order custom sizes based on die diameter and roller assembly specs. Packaging is custom, often wooden crates with internal foam padding. The supplier accepts ODM and OEM orders, indicating flexibility in design. Trade terms are FOB Zhangjiakou or CIF port, with lead times dependent on customization level.

Sourcing Fish Scale Shaped Roller Shell from Zhangjiakou Hongxing Machinery Co., Ltd. - China Import Guide
Before ordering, verify the exact dimensions and material grade of the roller shell against your pellet mill’s specifications. The supplier offers customization but does not provide engineering drawings - request CAD files or printed blueprints showing tolerances, groove pattern, and bore details. Confirm that the stated hardness (HRC 58-62) is backed by a test report from a certified lab, not just a supplier claim.
Logistics are shipped from Zhangjiakou port by sea or air. Lead time depends on customization but typically ranges from 30 to 45 days. Incoterms are usually FOB or CIF; buyers must confirm who arranges insurance and customs clearance. Payment terms are often 50% advance, 50% before shipment. Request a packing list with weight, dimensions, and protective measures for heavy steel components.
Quality inspection should include hardness testing at multiple points, dimensional checks with calipers, and visual inspection for surface cracks or decarburization. Request a material certificate (EN 10204 3.1 or 3.2) for the steel grade used. Inspect packaging for rust prevention - oil coating or vapor corrosion inhibitors should be applied. Retain a sample for reference in case of premature wear or failure.
