The product was ball milled with a Retch PM-400 planetary ball mill. For the ball milling, stainless steel jars and grinding balls were used. The ratio of jar volume (L):grinding balls (kg):sample weight (g) was kept constant for all the samples 1 : 0.8 : 40. The ball milling was performed in 1 h intervals with 30 min interval breaks at 300 rpm.

Since flap-type valves are hinged, long-term use eventually causes fatigue at the flexing point. Ball valves wear more evenly since the ball is free to rotate during operation and settle in a different position on the seat. Flap-type check valves have the advantage that they can more easily pass large solids entrained within the pumped fluid.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 - 50 % of the mill volume and its size depends on the feed and mill size.
