Gray Crusher Rotor - Heavy-Duty Impact Crusher Rotor Assembly for Mining & Quarrying
Product Overview
The gray crusher rotor is the core rotating component of a horizontal impact crusher, directly responsible for converting motor power into high-speed impact energy to crush rock, ore, limestone, and other hard materials. At Quzhou Horbon Mining Parts Co., Ltd., we manufacture and supply gray crusher rotors as complete assemblies or individual sub-components - giving procurement teams full flexibility to source exactly what they need from a single factory.
Our PFC1415P-compatible rotor assembly (Part No. 2105070001) is a prime example of our heavy-duty rotor manufacturing capability: a total assembled weight of 8,150 kg, rotor diameter of Ø1368 mm, overall length of 2807 mm, and a 4-row plate hammer configuration - engineered for primary and secondary crushing in high-throughput mining, quarrying, and aggregate production.
Whether you need a complete rotor assembly, a replacement rotor body, plate hammers, main shaft, bearings, or wedge blocks, Horbon supplies all 44 sub-components under one roof.

Key Components & Material Highlights
A gray crusher rotor assembly integrates multiple critical components. Horbon manufactures or sources every one of them:
Rotor Body
The structural backbone of the assembly at 4,043 kg. Precision-cast with machined hammer slots to accommodate a 4-row plate hammer configuration. Built for maximum impact energy transfer and long structural service life.
Main Shaft
Forged alloy steel shaft at 670.25 kg. Transmits torque from the drive assembly to the rotor body. As a critical structural component, it is manufactured using CNC machining and heat treatment quenching for dimensional accuracy and fatigue resistance.
Plate Hammers / Blow Bars
Four hammers, 447.75 kg each. The primary wear part that directly strikes feed material. Available in high-manganese steel, chrome-molybdenum alloy steel, and bimetal wear-resistant grades - material selected to match your feed hardness and abrasion requirements.
Self-Aligning Spherical Roller Bearings
Two units at 88.91 kg each. Absorbs heavy radial and axial loads while automatically compensating for shaft misalignment under impact loading - critical for stable rotor operation in heavy-duty conditions.
Bearing Seat / Housing
Precision CNC-machined bearing housings (201.03 kg × 2) maintain exact bearing alignment and provide an integrated oil reservoir for reliable lubrication.
Wedge Block System
16 pcs of Wedge Block 1 + 32 pcs of Wedge Block 2. Secures plate hammers firmly in rotor slots. The wedge locking design enables rapid hammer replacement without specialized tooling, significantly reducing planned maintenance downtime.

Labyrinth Seal System
Dual-ring labyrinth seals prevent dust ingress into the bearing zone and stop lubricant leakage - extending bearing service life and reducing unplanned maintenance.
Drive Pulley
Cast iron large-diameter drive pulley (521.63 kg) for V-belt power transmission. Dynamically balanced for stable high-speed rotation.
Material & Process Capabilities
Horbon applies rigorous material selection and manufacturing processes across all gray crusher rotor components:
High-Manganese Steel
Excellent toughness and work-hardening, ideal for impact wear parts.
Chrome-Molybdenum Alloy Steel
Superior hardness and thermal stability for high-stress structural parts
Bimetal Wear-Resistant Composite
Extended service life for plate hammers in high-abrasion applications
Heat Treatment & Quenching
Applied to structural and wear components for controlled hardness profiles
Precision Casting
Near-net-shape complex geometry components with consistent grain structure
CNC Machining
All critical-dimension surfaces (shaft journals, bearing seats, hammer slots) are finish-machined to tolerance
Quality Control covers the full production chain: raw material spectral analysis, Rockwell hardness testing (HRC), coordinate measuring machine (CMM) dimensional inspection, non-destructive flaw detection, and third-party inspection availability.
Applications
Gray crusher rotors manufactured by Horbon serve end-users in:
- Mining Operations - Iron ore, copper ore, gold ore, and other hard rock primary and secondary crushing
- Quarry & Aggregate Production - Limestone, granite, basalt, and river gravel crushing lines
- Cement & Building Materials - Clinker, slag, and construction waste processing
- Coal & Energy Sector - Coal sizing and preparation plants
- Recycling & Demolition - Concrete and construction debris reduction
Our rotors are compatible with major crusher brands including Metso, Sandvik, Terex, Trio, and a wide range of Chinese-standard (domestic) OEM models.
Why Source Your Gray Crusher Rotor from Horbon?
Horbon is a dedicated crusher parts manufacturer - not a trading company. Our factory in Quzhou, Zhejiang covers approximately 13,000 m², and every part on this page is produced or quality-controlled in-house. This means you deal with one supplier contact, one quality system, and one shipment for your entire crusher spare parts order - gears, bushings, bronze sleeves, main shafts, rotor assemblies, nuts, bolts, springs, oil seals, pulleys, and more.
Send us your part drawing, existing part number, or worn sample. We reverse-engineer and manufacture to match, with full OEM/ODM support. No minimum order complexity - we handle both single-component orders and complete rotor assembly procurement.
We supply rotor components compatible with Metso, Sandvik, Terex, Trio, and domestic OEM crusher models. If you're running a mixed fleet, Horbon is your one-stop procurement solution.
Standard lead time is 15–30 days from order confirmation. We maintain ready stock of common wear parts. Shipping is handled via FOB or CIF terms through Shanghai and Ningbo ports, with export experience covering Southeast Asia, the Middle East, Africa, Europe, the Americas, South Asia, and Australia.
Every shipment is backed by multi-stage QC: spectral raw material testing, HRC hardness verification, CMM dimensional inspection, flaw detection, and optional third-party inspection. Horbon provides quality problem free-replacement and 7×24 online technical support, including installation guides and video/photo assistance.
Frequently Asked Questions
Q: Can I order individual components of the gray crusher rotor rather than a full assembly?
A: Yes. All sub-components - including plate hammers, wedge blocks, main shaft, bearings, bearing seats, labyrinth rings, and drive pulleys - are available for individual order. Minimum order quantity is 5 pieces per part.
Q: What material options are available for plate hammers / blow bars?
A: We supply plate hammers in high-manganese steel, chrome-molybdenum alloy steel, and bimetal wear-resistant grades. Material selection depends on your feed material hardness and operating conditions. Share your application details and we'll recommend the best option.
Q: Do you support OEM/custom rotor manufacturing?
A: Yes. We accept customer drawings, sample parts, or existing part numbers for reverse engineering and custom manufacture. Both OEM and ODM arrangements are supported.
Q: How long is the standard production lead time for a gray crusher rotor assembly?
A: Standard lead time is 15–30 days. Wear parts such as plate hammers and wedge blocks may be available from existing stock for faster delivery.
Q: Which crusher brands are your rotor components compatible with?
A: Our components are compatible with Metso, Sandvik, Terex, Trio, and a wide range of Chinese domestic OEM crusher models. Provide your crusher model and part number for exact compatibility confirmation.
Q: What quality checks are performed before shipment?
A: Our QC process includes raw material spectral analysis, Rockwell hardness (HRC) testing, CMM dimensional inspection, flaw detection, and optional third-party inspection. Documentation is provided upon request.
