Identify Installations 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 and used parts.

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 familyStructure / process stagePublished key rangeSpare-part checks
Primary & Secondary SizersPrimary / secondary; inward-rotating twin rolls; hydraulic product-size adjustmentTypical recommended reduction ratio 4:1; legacy published selection range: roll diameter approximately 508–1,524 mm, roll width approximately 1,219–3,658 mmTooth profile, segment arrangement, roll width, gap, rotation and drive interfaces
Tertiary SizersTertiary; outward-rotating rolls; crushing between toothed rolls and adjustable sizing combsTypical recommended reduction ratio 4:1; roll diameter, width and product size selected for the projectAlloy-steel segments, sizing combs, roll barrels, spherical roller bearings and twin drives
Mineral SizersPrimary / secondary crushing of hard rock and clay-bearing ore; inward-rotating rolls; optional breaker barPublished maximum feed 1,200 mm, reduced to approximately 300 mm; adjustable roll spacingCrushing hammers, replaceable segments, breaker bar, liners, removal mechanism and twin drives
Fine-Grinding SizersLow-capacity, test or tertiary / quaternary fine crushing; inward rotation, reversible, twin drivesFixed or fluid couplings; shafts adjust forward/backward to compensate wear; no single published fixed model tableSegments or hardfaced roll surfaces, symmetrical bolted liners, bearing housings, gearboxes and couplings
Sampling Sizers / Roll CrushersSampling and low-capacity service; Mini-Sizers and small double-roll crushersCompact configurations of larger sizers / double-roll crushers; roll gap and tooth profile jointly control product sizeRoll 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.

Wear Parts

Crushing Segments, Sizing Combs, Breaker Bars and Frame Wear Parts

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

Segment Bolts, Clamps and Retainers

Segment Bolt & Retention Parts

Replaceable segments use dedicated fasteners. Replacement procedures involve threaded plugs, lifting eyes and hex-head retaining bolts. Identify threads, heads, lengths, preload, locking and associated parts as a set.

Spare Parts

Roll Shafts, Bearings, Direct Drives, Hydraulics and Seals

Drive and maintenance spares are listed separately. Roll shafts, bearing housings, gear reducers, couplings, hydraulic adjustments, seals and retainers require complete interface checks.

Gear Reducers and Direct-Drive Assemblies

Gear Reducer & Direct Drive Assembly

Current McLanahan Sizers use a motor, coupling and gear reducer mounted directly on the roll shaft. The image identifies a generic component category and does not establish a McLanahan model or interchangeability.

FAQ

Frequently asked questions

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, Mineral Sizer 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.

Submit McLanahan Sizer Nameplate, Serial Number, Drawings and Used-Part Details

Provide sizer family, full nameplate, serial and project numbers, roll width, tooth profile, shaft position and rotation, drawing, used-part photographs, dimensions, materials and feed conditions. We use these for identification, material assessment, manufacturing coordination, quality control and delivery.

Manufacturing Services in China

From Technical Assessment to Finished-Part Delivery

ANRANST provides customers worldwide with engineering assessment, production at certified foundries to the customer technical requirements, quality control and finished-part delivery for custom wear parts and industrial spares, with scope to support other custom industrial parts.

01

Drawing and Engineering Review

We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.

02

Material and Heat-Treatment Specification

Material grades and heat-treatment processes are specified order by order, stated in the technical agreement and tracked through production.

03

Quality Control

Drawing confirmation, material and process control, production tracking, inspection and acceptance coordination.

04

Finished-Part Delivery

We coordinate manufacturing, quality confirmation, packaging and delivery of complete finished parts in a workable, closed-loop supply process.

Provide the existing model, drawings, drawing, materials or operating conditions so we can identify the appropriate technical review and supply route.
