VSI Barmac Crusher for Sale: A Comprehensive Overview

The search for a VSI Barmac crusher for sale represents a strategic investment in high-quality tertiary and quaternary crushing technology. Originally developed by Metso (now part of Metso Outotec), the Barmac Vertical Shaft Impact (VSI) crusher is renowned for its unique rock-on-rock crushing principle, which provides exceptional product shape, reduction ratios, and the ability to handle abrasive materials. This article outlines the key features, applications, and considerations when purchasing a Barmac VSI, supported by comparative analysis and real-world evidence.

Core Technology and Advantages

Unlike conventional crushers that use metal-to-metal impact or compression, the Barmac VSI utilizes a high-velocity rotor that throws feed material against a stationary anvil rock shelf or into a dense stone-on-stone particle cloud. This autogenous crushing action offers distinct benefits:

• Superior Product Shape: Produces well-shaped, cubical aggregates critical for high-quality concrete and asphalt.
• Wear Cost Reduction: The rock-on-rock action minimizes wear on metal parts, as the wear is transferred to the feed material itself. Key wear components like rotor tips and cavity wear plates are designed for easy replacement.
• Versatility: Capable of fine grinding, grinding circuit optimization (pre-milling), and manufacturing sand from various feedstocks.
• Adjustability: Product gradation can be precisely controlled by adjusting rotor speed, feed rate, and the cascade of material flow.

Key Models and Considerations for Purchase

When evaluating a Barmac VSI crusher for sale, understanding the model series is crucial. The two primary series are the B-Series (e.g., B9100, B7150, B6150) and the earlier developed "Orange Series" Rotopactor models. Key considerations include capacity requirements, feed size, desired product size, and power availability.

The following table contrasts general characteristics to aid in preliminary selection:

Feature / Model Range	B-Series (e.g., B9100/B7150)	Older Rotopactor Models
Technology Era	Newer design, continuous refinement	Original/earlier design, proven over decades
Control & Automation	More advanced; compatible with modern automation systems like IC™ crusher automation	Manual or basic hydraulic adjustment systems
Parts Availability	Generally excellent through official channels	Available but may require sourcing from specialized suppliers
Typical Application Focus	High-capacity aggregate production, industrial minerals	Robust construction for demanding duties; often found in established operations

Note: Specific model suitability must be assessed by a qualified engineer based on actual plant data.

Real-World Application Case Study

A prominent example of the Barmac VSI's effectiveness is its application at the Tarmac-owned Linhay Quarry in Ashburton, UK. Facing the challenge of producing high-specification railway ballast and concrete aggregates from highly abrasive greywacke sandstone, the quarry installed a Metso Barmac B9100SE VSI in a tertiary crushing role.

The results were documented in industry reports: The B9100SE successfully produced precisely shaped 40mm railway ballast meeting Network Rail specifications. Crucially, it also generated a consistent supply of high-quality manufactured sand as a by-product from the same abrasive feed material—a task challenging for other crusher types. This installation demonstrated the model's durability in abrasive applications and its value in maximizing product yield from difficult raw materials.

Frequently Asked Questions (FAQ)

1. What is the main difference between a Barmac VSI and a cone crusher?
While both are used in secondary/tertiary stages, cone crushers use compression crushing between a mantle and concave liner, producing more flaky products under certain conditions. The Barmac VSI uses high-velocity impact and rock-on-rock attrition to produce superior cubical shape and is more effective for sand manufacturing or fine grinding. They are often used complementarily in circuits.

2. Can a used Barmac VSI effectively manufacture sand?
Yes absolutely. The rock-on-rock principle is inherently suited for sand production. When purchasing used equipment inspect key wear parts like the rotor (tips/back-up tips), feed tube/distributor plate cavity wear plates Assess their remaining life as these directly impact product gradation consistency

3 What should I inspect when viewing a used Barmac crusher for sale?
Critical inspection points include:

• Rotor Assembly: Check for cracks imbalance or excessive wear on tips trays
• Main Shaft & Bearings: Investigate for any signs of overheating oil leaks or unusual play
• Drive System: Inspect sheaves belts motor condition
• Internal Lining/Wear Parts: Measure remaining thickness of wear plates anvils etc
• Operational History: Request maintenance records hourly usage logs

4 Are parts readily available for older models?
Metso Outotec maintains extensive spare part support even for legacy models Additionally there exists a robust independent aftermarket specializing in compatible replacement parts rotors rebuilds ensuring long term operational viability

5 Is it possible to retrofit automation on an older manual model?
To some extent yes Basic hydraulic setting adjustments can often be upgraded However full integration with modern process control systems like IC™ may be limited compared to newer factory-equipped models A detailed technical review by specialist is recommended

In conclusion procuring a VSI Barmac crusher whether new or used involves evaluating its unique crushing action against specific operational goals From producing premium aggregates to solving sand shortage issues its proven technology backed by documented case studies makes it significant asset in mineral processing aggregate production circuits
