Steel Ball Mills 20 – 100 litres

Steel ball mill type SKTM60

Jars for jar mills are available to a maximum of about 32 litres. Above this size the jars and their contents become too heavy for easy operating. From 20 litres to 70 litres and for 100 litres on demand we have the small and operator friendly SKTM and TNM series of small ball mills. From 100 litres and above we refer to our other possibilities. The emptying of the mill is by means of a pendulum motion which fills the collecting tank. The SKTM series are for dry process applications. The TNM series are for wet process applications.
