Wear Parts

Roller, poles and sidebar with slot wear parts

Pressure, impact and wear mechanisms differ from the roller surface poles to roll end ends; materials and the process installation position Determinations separately.

Forged/heaped rollers

Forged / Welded Roll Body

Roller surface stacking and rely on the material pad to form a natural wear resistance protection. The roller diameter, roll widths of scale welding type in bulk packaging moldings are required for corrugation by machine diagram as well with hard surfaces or edge structures that must be confirmed according their mounting profile

Material Selection: Roller cores, transition layers and hard surfaces are different Materials and Processes The system needs to be determined in combination with grinding, pressures and repair cycles as well.

Roller End Edge Protection

Roll Edge Protection

Protection of the high wear area in roller body end, reducing edge stripping and side leakage. Separations / fixed surface to be secured with a pin zone as well for right-handed roll positions must confirm by original figure

Material Selection: The edge zone shock, cutting and stress concentration is obvious. Resilient wear alloys can be used cemented carbide The nesting block or composite solution requires verification of the anti-collapse capability.

Feed Chute Liner

Cover the feed drop-off and pillar channels, control uniform feedings as well to protect slot shell. The hole lineage is confirmed by a slide of holes in rowing or downfall space; interface with sidebar canals will be verified on its slip chart

Material Selection: By block rate, deflections and water content impact wear Selecting partitions wear-resistant steel plate, rubber or polyurethane Composite Programs and Consolidated Filling Liners Risks of depriving.

Discharge Chute Liners

Discharge Chute Liner

Protect the exit and transshipment of ballasts, which withstand sliding wear as well local shocking with bulk. Contour lines are confirmed by a droplet slide diagram for profiles or holes in rowings; tapping is also recognized through an interface between downstream equipment (SUV).

Material Selection: Choose by the pressure cake strength, water content rate and speed as well. wear-resistant steel plate Or elastic Composite liners and focuses on controlling the wear of seams, edges or fixed parts.

Why this page is not created polycom (r) Unification model Code?

Because the current factory page is clearly configured according to materials, processes and project requirements. The public information does not provide a uniform model table for all of this because it has no standard identification system in place on its own site as well than at any other time when you can identify parts with nameplates or roller diameter (Roll width), roll surface form(Rail size) etc; serial number/drawn figure must be determined by reference).

Studded Roll Surfaces Can composite casting rollers and stacked roll bodies be directly interchangeable?

No. Three Rollers Construction Pressure, milling ratios and edge protection methods Item Configuration Differently, the full roller unit must be combined with operating conditions Assessments.

Can roll diameters and roller width only be provided Manufacturing bearing Or hydraulics?

Cannot. It is also necessary to confirm the position of fixed/floating rollers, shaft neck and seat hole; bearing model, and the gaps hydraulic cylinder Size and pressure, sealing Interfaces and Drawing Revision.
