Cleaning Wet & Sticky Rock

Cleaning in tough/wet conditions can be extremely challenging. MDS Trommels have drum cleaners allowing them to excel where other machines fail by preventing blinding from the heavy, sticky material coming off the rock.

Drum Cleaners Reduce Downtime and Maximize Profitability.

Drum cleaners prevent blinding by removing built up material from the screening surface.

Applications

Screen Rock Up To 50″

Larger units, like the M820 can screen rock up to 50″ and are effective in cleaning clay-bound stone or rocks mixed in clay or other sticky materials

Demolition Waste

Demolition recycling is one of the key applications of MDS Trommels, where they are often used to separate building waste, bricks, concrete and topsoil with sand. They are highly mobile and easily moved onto recycling sites or retrofit into existing recycling systems.

Screen and sort Material By Size

What is Rip Rap

Rip Rap or Armour Stone, as it is often called, is a rock product used to line shorelines, stream beds, bridge abutments, and other shoreline structures to protect against water or ice erosion.

The only criteria for the rock used to produce rip rap is that it be durable and won’t deteriorate during freeze/thaw cycles or when exposed to water.

There are diferent classifications for rip rap based on size, weight and allowable velocity (m/s). The province of British Columbia has developed its own Standards for Riprap that provides guidance for selection, sizing and placement of riprap. You should consult these to learn more.

Typical Applications Include:

  • Rip Rap/Armour Rock
  • Blast Rock
  • Granite
  • Limestone
  • Sticky/Wet Material
  • Demolition Waste
  • Primary Processing
  • General Recycling
  • Wood Waste
