Black Diamond · Heavy-Duty · Shalemaster — roll surfaces, shafts, belt drives and tramp relief.
Material selection, drawing-based manufacturing and supply coordination for roll wear surfaces, shafts and supports in coal, limestone and wet, sticky material crushing. Double roll crushers and DDC-Sizers have different drives and roll assemblies, requiring separate parts identification.
Provide roll diameter × width, tooth profile, roll gap and single- or dual-drive configuration.
| Series | Main Configuration | Selection التفاصيل |
|---|---|---|
| Black Diamond | Single or dual V-belt drive; clean coal and friable materials | Roll surface profile, roll diameter × width and pulley interface |
| Heavy-Duty | Heavy-duty double rolls; limestone, gypsum and run-of-mine coal | Tooth profile, bearing housings, roll shafts and tramp relief mechanism |
| Shalemaster | Differential roll speeds; V-belt and reducer drive; wet, sticky materials | Special tooth profile, individual roll speeds and scraper clearance |
Roll diameter, width and tooth profile are project-specific. Check drawings and serial numbers even for parts within the same range.
Select wear surfaces for abrasion, impact and adhesion. Confirm materials together with the existing part design, heat treatment and fixing method.
Roll Shells & Segments
Directly contacts the feed material. Specify fixed or movable roll, diameter, width and segmentation in your enquiry.
Materials and Operating Conditions: Consider toughness and work hardening under impact, and wear-resistant alloys or repairable surfaces under abrasion.
View Parts and Materials →Crushing Teeth
Tooth height, pitch, arrangement and root design affect feed gripping and product size. Use tooth drawings, not visual similarity, for matching.
Materials and Operating Conditions: Balance tooth-tip wear, tooth-root impact toughness and repair weldability.
View Parts and Materials →Side & Bottom Liners
Protect the frame interior and base along the material path. Specify hole spacing, plate thickness and maintenance sections.
Materials and Operating Conditions: Assess wear-resistant plate for impact resistance and installation machining; it is not a universal OEM material specification.
View Parts and Materials →Roll Scrapers
For removing adhering material. Confirm that a scraper is fitted, then check the working clearance between the blade and roll surface.
Materials and Operating Conditions: Consider wear-resistant steel while preventing contact between the hard scraper edge and roll surface.
View Parts and Materials →Match drive spares by shaft diameter, keyway, bearing designation and drive arrangement.
Roll Shafts
Check shaft shoulders, keyways, roll shell connections and bearing fits.
Materials and Operating Conditions: Assess quenched and tempered alloy steel against load, fatigue strength and fit requirements.
View Parts and Materials →Bearings, Housings & الموانع
Check fixed or movable support positions, bearing designations, lubrication and dust seals.
Materials and Operating Conditions: Specify housing and seal materials separately. Ordinary wear-resistant steel is not a substitute for bearing rolling-contact steel.
View Parts and Materials →Sheaves, V-Belts & Gear Reducers
Single-drive machines transmit power between rolls by belts; dual-drive machines power each roll independently. Check the Shalemaster reducer and differential-speed arrangement separately.
Materials and Operating Conditions: Machine pulleys, bores and keyways to drawing; specify V-belts by size and matched-set quantity.
View Parts and Materials →Spring-and-Toggle Tramp Relief
The movable roll yields when tramp material enters. Check springs, toggles, pins and return position as a complete mechanism.
Materials and Operating Conditions: Specify springs and load-bearing parts against fatigue loads, heat treatment and original dimensions.
View Parts and Materials →Hydraulic Roll Adjustment
For optional hydraulic adjustment, check cylinder bore, stroke, mounting trunnions and roll gap range.
Materials and Operating Conditions: Select piston rods, seals and mountings separately for the hydraulic system conditions.
View Parts and Materials →Brand, roll diameter or tooth profile alone cannot establish interchangeability. Check the drive, roll shafts, bearing housings, connection dimensions and tooth drawings separately.
