MSI Horizontal Balers


The McDonald Services family of horizontal extrusion balers vary in size from the thirty by thirty inch feed model to the sixty by forty six inch feed model. Of the forty different models offered, the "thirty-thirty" and the "sixty forty-three" models are the most popular.

OE-330 30/30

The smaller 30" by 30" extrusion balers are popular with customers who are working with hard to bale materials. The width to height bale dimension reversal (30 " wide by 40" high) improves bailing efficiency and handling of hard to bale materials.

AT-643 60/43

The ability to handle large pieces of waste plus high volume production are two reasons why customers choose our 60 " x 43 " model extrusion balers. Their size makes these balers ideal for commercial recyclers, municipal land fill operators, and waste haulers.
