There are two key reasons for high-energy consumption, low throughput and a rise in temperature of ground materials coming from a hammer mill. They are: 1. Poor hammer milling capacity Large amounts of colliding energy is wasted as heat due to the high rate of eccentric collision. This only makes materials spin and bounce around in grinding chamber, and does not lead to further size reduction....
Hello Good article and very interesting , not sure how relevant it is because the beater tip speed was low at 60m/sec normal speed would be 100m/sec + for fine grinding on a 2 mm screen that was used for the test ,
Phil, tip speed varies for fine grinding based on the raw material. Your industry is "food". Some fibrous materials benefit from a lower tip speed. Others may grind optimally at higher tip speed. Other variables are factored in, also.
