Due to their robust design, adequate motor power and the replaceable wear plates on the bottom and sides of the drum, this mixer has a very long operational lifetime. The design of the paddles and beater, and the appropriate speed of rotation combine to produce very thoroughly mixed materials. The beater beam is fitted with a side scraper which assists in keeping the drum side clean. To improve the effectiveness further, the position of the paddles is adjustable vertically and transversely. The adjustable legs allow for variable outlet and loading heights.
