HPGR CHEEK PLATE / SIDE LINER

HPGR Side Liners and Cheek Plates

Wear protection and material-bed containment beside the roll gap · Identify by side, profile and clearance

Side liners sit beside the roll gap and material bed, providing lateral containment and protecting adjacent structures. ANRANST checks left/right orientation, fixed or floating roll side, profile, hole pattern, working-surface material, roll-end clearance, failure records and drawing numbers for technical review, quality control and finished-product delivery.

Equipment HPGR units with lateral material-bed containment

Installation Position Both sides of the roll gap and feed bed

Operating Conditions Abrasion, compression, impact and lateral material leakage

Identification requirements Model, installation side, profile, hole pattern, clearance and drawing number

Category image for identifying plate-type parts. Confirm left/right orientation, fixed or floating roll side, hole positions, thickness and working profile against drawings or an approved sample.

Part Function

Contain material beside the roll gap and protect side structures

Side liners and roll ends form the lateral boundaries of the material bed. Working clearance between the plate face, roll end or flange affects leakage, local uneven wear and edge pressure distribution. Similar appearance does not establish interchangeability.

A machine may have left- and right-hand parts, fixed- and floating-roll-side parts, upper and lower parts, or segmented assemblies. Retain position markings during inspection and record adjustment shims, fastening methods and actual clearances.

Orientation identification Left/right, fixed/floating roll side, feed/discharge end

Geometry identification Profile, hole pattern, thickness, recessed holes, chamfers and segmentation

Clearance identification Working clearance to the roll end, flange or edge structure

Material identification Backing plate, working layer, connection method and heat-treatment condition

Position and Performance

Check installation position, clearance and wear layer together

Plate wear changes material-bed boundaries and roll edge conditions as well as reducing part life.

Fixed roll side

Check mounting datums, plate flatness, hole positions and roll-end clearance to prevent one-sided wear caused by assembly errors.

Floating roll side

Account for floating roll travel and clearance at different load positions to avoid interference, trapped material or abnormal leakage.

High-wear feed zone

Subject to material erosion, coarse-particle impact and lateral compression. Confirm the working profile and local material selection using site wear patterns.

Roll-end edge zone

Adjacent to the roll end, flange or edge segment. Excessive clearance can allow leakage; insufficient clearance can cause rubbing and thermal damage.

Segments and connections

Segmented plates, fastening holes, clamping plates, shims and adjustment structures jointly establish location. Retain the assembly sequence during replacement.

Left/right set management

Organise sets by installation side and position number. Record actual thickness, wear and replacement intervals to prevent mixing left- and right-hand parts.

Materials and Manufacturing Processes

Select materials for impact, wear, support and connection conditions

Material families support engineering selection. Confirm grade, hardness, thickness and processing against drawings and technical agreements.

Quenched and Tempered Wear Plate For plates requiring overall toughness, machinable holes and stable shape. Check thickness, flatness, hole positions and control of heat effects.

Bimetallic Composites Evaluate for high-wear surfaces with reliable backing support and connections. Verify the integrity of the wear layer, backing plate, edges and hole areas together.

High-chromium cast iron wear layers or castings Evaluate only with controlled impact and suitable support and assembly conditions. High hardness does not establish resistance to fracture.

Hardfacing and composite repairs For backing plates or working surfaces suitable for repair, control weldability, preheating, interpass temperature, deformation and final profile.

Selection sequence: feed and roll-press duty → lateral erosion and compression → plate wear and clearance loss → material and structural options → dimensional and process inspection → installation records.

Failure Diagnosis

First identify wear, fracture, loosening or loss of clearance control

Similar visible symptoms can result from material, installation, clearance or feed problems.

Observed condition	Priority checks	Improvement Options
Rapid plate thinning or grooving	Feed abrasiveness, flow direction, working-zone position, material layer and effective thickness	Optimise material, profile and replacement interval by wear zone
Edge chipping or complete plate fracture	Impact, unsupported areas, hole edge distances, fastener preload, material toughness and internal defects	Improve support and connections, and check toughness and manufacturing quality
Warping, loosening or hole-area damage	Plate shape, mounting surface, shims, tightening sequence, hole pattern, heat input and operating vibration	Restore mounting datums and control plate shape and fastening procedures
One-sided wear or local rubbing	Left/right orientation, fixed/floating roll side, roll-end runout, plate position and working clearance	Recheck installation and clearance over the actual range of movement
Increased lateral material leakage	Remaining thickness, roll-end clearance, profile match, uneven feed and adjacent edge structures	Restore material-bed boundaries and inspect adjacent roll surface parts
