Materials are dispensed by a positive feed  delivery mechanism.   Each revolution of the shaft moves the same amount of material from the beginning to the end of any load, ensuring quality and consistency.

Each aggregate can be dispensed individually at any time, using our independent clutch system.  This greatly decreases calibration  time.  It also enables the operator to make a wide range of products, such as grout mixes with sand and cement, or pervious concrete with stone and cement.  It allows for sand or stone to be off-loaded individually, either to reload with a different size, or to dispense either product to meet a customers' need.  There is no spillage of sand or stone along the length of the unit, due to our unique chain design.  This allows for a cleaner job and a cleaner chassis.

The auger drive motor is located at the bottom of the auger, putting the horsepower where it is most needed.  This design also allows for easy auger removal and wear blade replacement.  Our patented chain drive system lasts longer than belt systems.  This also means lower maintenance costs, since the chain seldom needs to be replaced.  Weight distributions are run on every unit we mount, ensuring compliance with D.O.T. guidelines in any state.  We offer multiple chute designs for a variety of applications.  Operator training is offered at the customer's location, along with unit calibration.  Training schools are held on various dates throughout the year at our company headquarters as well as other states and countries.
