Pulverisers

DEMCO Pulverisers deliver efficient on-site processing. Available for a range of carrier sizes, competitively priced and backed by a 3-year warranty.

Breaking concrete is one thing, processing it efficiently is another. DEMCO pulverisers are purpose built for the work that follows demolition, turning bulky concrete into manageable material while stripping rebar and separating components cleanly on site.

Heavy-duty steel construction for consistent performance under tough conditions

Available in fixed and 360° rotation configurations to suit carrier size and site needs

Replaceable wear parts reduce downtime and keep maintenance straightforward

MAINTENANCE

How do I store my rock breaker?

Keep it in a dry environment. If stored outdoors, position the chisel end low and the hitch end elevated to prevent moisture entry. Proper storage avoids internal corrosion. Keep in mind that long-term exposure to moisture increases the risk of internal corrosion inside your attachment.

Can I leave a rock breaker outside?

Short-term outdoor storage is acceptable if the breaker is stored with the chisel end pointing downhill. For long-term storage, indoor or properly sheltered conditions are recommended to reduce the risk of internal corrosion.

How do I select the correct size rock breaker for my excavator?

Breaker selection needs to account for carrier operating weight, hydraulic flow rate, working pressure and allowable back pressure. Specification tables can be found on the DEMCO website and DEMCO suppliers are always happy to help out with selecting the right sized rock breaker for your machine. 

What routine checks are important before and after using a breaker?

Operators should regularly inspect tool wear and check hoses and fittings for any leaks. Regular greasing is a must, as is ensuring hydraulic flow and pressure settings are verified. Early inspection and detection of any minor issues, prevents any major issues cropping up in the long-term.

Why has the breaker impact weakened?

Common causes include low nitrogen charge, high back pressure, restricted couplers or worn seals. Proper hydraulic testing is needed to pinpoint the issue.

How can I be sure my breaker is working to full capacity?

Check nitrogen pressure, supply-line pressure, return-line back pressure, and flow rates. Accurate measurement ensures consistent performance.

What does frequency loss with heavy blows indicate?

Usually excessive back pressure, which slows piston return and reduces blow rate. Inspect hoses, any partially closed valves and couplers to correct.

WARRANTY AND SERVICE 

What warranty coverage is available for DEMCO rockbreakers?

All breakers come with a three-year manufacturer warranty and access to a dedicated service network in your local area, including parts, service and technical assistance.

How long will I have to wait for new rock breaker parts?

Service kits, wear parts, seals, bushings and tools are held locally for quick dispatch when you need them. Shipping time will depend on your location.

How often does a rock breaker need to be serviced?

Daily inspections are a good maintenance habit to get into, along with regular greasing. Compact breakers also require a nitrogen pressure check at least once a year to maintain performance.
