Rotary Bit Cutter Excavator

 

Model: DWRC- 75

Model: DWRC – 110

Model: DWRC- 150

  Feed the dredge pump or just stir and screen material.   Rotary excavators are engineered to feed the dredge pump. There are three important elements in a properly engineered cutter drive. First is adequate horsepower to aggressively excavate material. Second a oversize shaft and gearbox to handle the shock loads created by the cutter and provide long service life. Thirdly a basket that does not plug with clay or rock  and can efficiently screen oversize that can not pass the pump impeller. Our cutter basket is innovative, like most of our products. Our cutter basket solves many common problems with the cutter style basket.  Our basket resists clay fowling, rock pegging and rock nesting. These are the three most common issues with a rotary cutter. Many times producers fault the deposit and not the cutters capability to deal with the deposit.  The overall design of our rotary excavators is rugged and built to last.  Our lowest horsepower model is the DWRC-75.   Our mid HP model is the DWRC-110.  For the larger dredges our model DWRC- 150 hp. Over 90% of dredges have a rotary excavator. This is for good reason. If a properly designed system in a deposit of free flowing material and the proper basket design, the rotary basket wins. Only for the most difficult deposits do we recommend our chain driven excavator. In those deposits our chain driven excavator will out produce a rotary cutter.

.    Common observations for the dredge pump suction means:

1. Most cutters are underpowered.

2. Do you have a hi vacuum from, excessive lift or a partially plugged basket ?

3. Can production can be increased by a larger pump or the proper equipment?
