Refurbished 50 Inch Raymond Roller Mill: Features, Specs & Availability

If you’re in the market for a refurbished Raymond mill 50”, you’re probably asking the same questions most buyers do: What’s been rebuilt? How will it perform? Can I trust that it’s ready to run?

Buy Now

This guide covers everything you need to know about the 50 inch Raymond roller mill, from technical specs and included components to rebuild quality and how to check availability.

50 Inch Raymond Roller Mills: The Basics

The 50″ Raymond vertical roller mill, also known as the 5057 model, is a widely respected piece of used industrial grinding equipment known for its durability and performance. It’s designed to pulverize, dry, and classify material all in one step, making it a highly efficient solution for a wide range of applications, from limestone to gypsum.

Whether you’re looking for a used Raymond mill rebuilt with quality-tested components or simply need a vertical grinding mill for sale that’s ready to plug into your operation, the 5057 offers excellent flexibility.

Breaking Down Its Full Technical Specifications

Understanding the specs is essential when evaluating a used vertical roller mill for sale. Here’s what you can expect from a rebuilt 50” model:

Performance

Material Capacity varies depending on material type and fineness:

  • Limestone (95% passing 18 mesh): Up to 8.8 tons/hr (7.1 US tons)
  • Limestone (85% passing 200 mesh): Up to 7.1 tons/hr (5.7 US tons)
  • Limestone (99% passing 325 mesh): Up to 4.6 tons/hr
  • Gypsum (90% passing 100 mesh): Up to 11 tons/hr (8.5 US tons)
  • Feed Size Range: ~1/2″ to 1-1/2″ (10–40 mm)
  • Fineness Control: Adjustable from coarse to 99.998% passing 325 mesh
  • Water Evaporation: Handles up to 1,800 lbs/hr via air-swept drying

Dimensions & Power Requirements

  • Mill Diameter: 50 inches (1270 mm)
  • Weight: ~80,000 lbs (approx. 8,000 lbs with motor)

Recommended Motors:

  • Mill: 100 HP (75 kW)
  • Fan: 60 HP (45 kW)
  • Classifier: 30 HP (22 kW)
  • Airflow: Nominal 10,000 CFM; maximum 12,000 CFM

What’s Included in the Rebuild?

Every refurbished 50 inch Raymond roller mill is rebuilt with precision to ensure dependable long-term performance. Here’s what typically gets serviced or replaced:

Grinding Components

  • Rollers and Rings: Resurfaced or replaced as needed, ensuring even wear resistance
  • Bearings: Replaced to reduce friction and vibration
  • Shafts: Inspected and aligned for smooth operation

Classifier and Blower

  • Classifier Vanes: Repaired or replaced for consistent particle sizing
  • Fan Assembly: Balanced and rebuilt for optimal airflow and drying performance

Structural and Mechanical

  • Gearbox: Inspected and rebuilt with new seals and lubricants
  • Housing and Liners: Repaired for integrity and safety
  • Motor Mounts and Couplings: Realigned or replaced to support reliable power transmission

Testing and Quality Assurance

Rebuilt mills are test-run to verify vibration levels, airflow, throughput, and classifier performance. The result is a reliable machine that’s ready to be put back into service — often with better longevity than when it was brand new.

How This Mill Compares to Other Raymond Models

Raymond mills come in various sizes and configurations, but the 5057 strikes an ideal balance of capacity and footprint for many mid-sized operations.

Compared to smaller models like the 3036, the 50 inch Raymond roller mill delivers significantly more throughput and finer control of particle size. While larger models exist, the 5057 is often preferred for its versatility in both large and small batch processing, especially in operations where changeover and maintenance accessibility matter.

Why Choose a Refurbished Raymond Mill?

Refurbished doesn’t just mean “used.” A refurbished Raymond mill 50” has been thoroughly inspected and reconditioned, offering:

  • Extended Wear Life: Thanks to replacement of worn components and optional hardfacing.
  • Performance Assurance: Test results confirm the mill’s efficiency and output.
  • Cost Savings: Significant discounts over brand-new mills, with similar reliability.

For buyers who want to reduce capital expense without sacrificing performance, a refurbished 50 inch Raymond roller mill hits the sweet spot.

Inventory may vary, but mills like the 5057 are often available for purchase and can be configured to match your system requirements. Ask about:

  • Motor options to match your existing power specs
  • Hardfacing upgrades for extended wear life
  • Classifier upgrades for tighter particle size control
  • Skid-mounted configurations for faster installation

Warranty and Support

When you purchase a used vertical roller mill for sale, you want more than a handshake. Here’s what to expect with a quality refurbished unit:

  • Limited warranty on rebuilt components
  • Post-sale technical support for installation and operation
  • Replacement part availability for ongoing maintenance
  • Documentation verifying rebuild details and performance tests

Don’t settle for a mystery mill from an auction listing. Buying from a vendor who stands behind the machine ensures peace of mind.
