RDS-20

Easy to move, Simple to operate, Quick to set-up and Ideal for boosting productivity, the RDS-20 unit

increases production by up to 20 percent by splitting oversized material to return to the crusher on two

decks, rather than one.

Features

• The closed-circuit design can be set to produce one sized product by returning the top two screen decks

back to the conveyor for further crushing. Operators can also set the machine to produce two sized and

one oversized product.

• Uses one power source to run a complete crushing operation and three auxiliary outlets.

• The optional, patented Hydraset Hopper™ simplifies the connection and removal of the hopper/feeder

so just one operator can prepare the unit for transportation in minutes.

• IROCK’s exclusive ROCK BOX design reduces the impact on the discharge point by allowing crushed

material to build into a natural rock shelf.
