Key Facts & Figures at a glance

The VeRoLiberator^® is a vertical impact crusher with very low energy consumption, near complete particle liberation, high reduction ratios, and operates dry.

Technological principles of the VeRoLiberator^®

• Vertical quadruple axle-in-axle system
• Gravitational free-fall of material through the comminution cylinder
• No energy used for lifting of material, tools or casing
• Several tools on three levels rotate clockwise and counterclockwise 
• Turbulent particle flow through machine 
• Multiple high velocity impacts crush ores, rocks, and slags
• Rotational speeds can be adjusted to the individual input material
• Modular set-up, for easy maintenance

Key parameters

• Throughput of approximately 100 to 130 t per hour
• Low energy consumption of 3 to 7 kWh/t output
• Particle size reduction ratio of up to 6.250 from continuous single-pass comminution
• Very high degree of particle liberation

Good to know

• 100% dry operating system, no process water needed
• No grinding media
• Very low noise level (85 dBA under full load)
• Very low dust level (encapsulated wind-draft filter system)
• Adjustable product particle size from coarse to fine
• Easy and fast maintenance, short down time for service
• Flexible design and layout
• Adjustable operating parameters, e.g. speed, number, shape or alloy of tools
• Possibility of down- and upscaling
• Modular set up for easy transportation and installation
• Mobility to operate within open pit mines (for in-pit crushing and conveying, IPCC)
• Low safety risk - no external moving parts
