Identify التركيبات and Spares across Five Current Sizer Families

McLanahan does not publish one fixed model table. Primary & Secondary, Tertiary, Mineral, Fine-Grinding and Sampling Sizers are configured for material, feed and product sizes. This page retains the series, typical dimensions, structures and part routes needed for spare-part checks. Before manufacture, confirm nameplate, serial number, general arrangement, drawing references and used parts.

Standard Models and Key Dimensions

Current McLanahan Sizer Families and Identification Ranges

The current catalogue groups products by application and structure, not a single model code system. Converted imperial dimensions and other values are typical published selection ranges, not manufacturing dimensions for an individual machine.

Current product family	Structure / process stage	Published key range	Spare-part checks
Primary & Secondary Sizers	Primary / secondary; inward-rotating twin rolls; hydraulic product-size adjustment	Typical recommended reduction ratio 4:1; legacy published selection range: roll diameter approximately 508–1,524 mm, roll width approximately 1,219–3,658 mm	Tooth profile, segment arrangement, roll width, gap, rotation and drive interfaces
Tertiary Sizers	Tertiary; outward-rotating rolls; crushing between toothed rolls and adjustable sizing combs	Typical recommended reduction ratio 4:1; roll diameter, width and product size selected for the project	Alloy-steel segments, sizing combs, roll barrels, spherical roller bearings and twin drives
Mineral Sizers	Primary / secondary crushing of hard rock and clay-bearing ore; inward-rotating rolls; optional breaker bar	Published maximum feed 1,200 mm, reduced to approximately 300 mm; adjustable roll spacing	Crushing hammers, replaceable segments, breaker bar, liners, removal mechanism and twin drives
Fine-Grinding Sizers	Low-capacity, test or tertiary / quaternary fine crushing; inward rotation, reversible, twin drives	Fixed or fluid couplings; shafts adjust forward/backward to compensate wear; no single published fixed model table	Segments or hardfaced roll surfaces, symmetrical bolted liners, bearing housings, gearboxes and couplings
Sampling Sizers / Roll Crushers	Sampling and low-capacity service; Mini-Sizers and small double-roll crushers	Compact configurations of larger sizers / double-roll crushers; roll gap and tooth profile jointly control product size	Roll bodies, tooth profiles, bearings, gearboxes, seals and project interfaces

Parts within one family vary with material, feed, product size, tooth profile, roll width, rotation, drive and installation. “DDC-Sizer” alone is insufficient for a quotation; provide the full nameplate and installation records.

Crushing Segments, Sizing Combs, Breaker Bars and Frame قطع الغيار المستهلكة

Separate segments, tooth working layers, sizing combs, الكسارة المسننة للمعادن breaker bars, frame liners and retainers by actual position. Candidate materials support preliminary service assessment only.

Replaceable Crushing Segments and Hammers

Replaceable Segment & Crushing Hammer

Primary, Secondary, Mineral and Fine-Grinding designs use serviceable crushing rolls. Check family, shaft position, tooth profile and count, helical arrangement, rotation, retention and original tooth height.

Material selection: Official Tertiary information specifies replaceable alloy-steel segments. Confirm the actual material, heat treatment, hardfacing and hardness against original drawings, impact and abrasion.

Tooth Crests, Flanks and Hardfaced Working Layers

Tooth Profile & Hardfacing Layer

Reduced tooth height lowers capacity and accelerates wear. Compare against new-tooth height or a profile template during maintenance. Restore by hardfacing only where the original tooth design permits it.

Material selection: Assess tooth-body toughness, working-layer wear resistance and welding heat effects together. Surface hardness alone cannot replace the original process requirements.

Frame Liners, Top Plates and Side Protection

Frame Liner, Top Plate & Side Protection

Fine-Grinding designs use symmetrical bolted wear liners. Frame, side-wall, inlet and outlet protection on other families varies by project. Check segmentation, thickness, hole patterns and removal access.

Material selection: The manufacturer specifies wear-resistant materials without one universal grade. Screen candidates by impact, sliding wear and structural rigidity, then follow original drawings and inspection requirements.

Why is there no fixed McLanahan model table here?

McLanahan's catalogue configures five product families for project conditions rather than providing one fixed model code covering all equipment. ANRANST publishes only traceable families and documented ranges.

Can DDC-Sizer, الكسارة المسننة للمعادن and Tertiary Sizer segments be interchanged directly?

No. Families, shaft rotation, tooth profiles, roll widths, comb or breaker-bar structures, retention and project configurations differ. Check complete model, serial number, shaft position, drawings and used parts.

Why are McLanahan OEM part numbers not listed?

Available records and public manufacturer pages do not provide OEM numbers that can be cross-checked against a specific family, position and installation. Numbers can be added when manufacturer catalogues, drawings or reliable installation lists provide that evidence.
