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.
