Crushing and compacting in a single step
New vibration crusher drum with newly designed tool holders for Hamm HC series compactors
HAMM have announced new compactor models featuring a new vibration crusher drum that has been designed specifically to crush and compact mixed soils, rocks such as basalt and granite, and other construction materials of comparable pressure resistance in a single step.
For countries with exhaust emission standard EU Stage V/EPA Tier 4f, the new HC 250i C VC model is available now, whilst for countries following the Tier 3 exhaust emission standard, the new HC 250 C VC will be available from the autumn of 2024.
Hamm say that by deploying VC compactors, processes on site can be streamlined, reducing the work and expense needed for material preparation and transport, and cutting CO2 emissions by up to 50%, depending on the application.
As with the predecessor series, the new models feature the initials ‘VC’ (Vibration Crusher) in the type designation. Featuring powerful Deutz engines and reinforced components around the front frame, three-point articulation, and the underbody, the new compactors are well-equipped for tough applications.
The separate ‘C’ in the type designation also symbolizes a reinforced drum drive, capable of inclines of up to 60%. The 25-tonne machines are supplied with heavy-duty tyres and the Easy Drive operating concept as standard, whilst for operator comfort, a seat with extended backrest comes as standard and an air-sprung driver’s seat can be selected as an optional extra.
A highlight of the new VC compactors is the newly designed tool holder system. This is compatible with round-shank cutting tools for stone, as well as wear-resistant heavy-duty cutting tools with carbide tips and hard facing for abrasive stone or hard stone.
The configuration of the tool holder system and the way the tool inserts attach have been designed to ensure assembly and removal are quick and easy with no need for specialist tools, keeping maintenance and servicing costs low. Existing machines (H 25i VC/3625 VC) can also be fitted with the new-design tool holder system by switching the drum. Transport rings are available for easy transport.
The new VC compactors are suitable for a wide range of applications. In addition to crushing and compacting geological material to create a stable substrate, the machines can also be utilized to level rubble in landfill sites or to pre-crush and loosen stone in road planing and surface mining, taking much of the hard work out of subsequent processes such as layer-by-layer milling off.
