The Ball Mill is responsible for diverting approximately 70% of wheelie bin waste from landfill and is the only one of its kind in the UK at present. The Ball Mill is a huge drum similar to a washing machine that contains 42 tonnes of steel balls. Leicester city's waste is fed into the drum, which rotates causing the balls to pummel and grind ...

August 29, 2016. It's hard to prove that glass sparks, except finding a reference to it's piezoelectric properties. But that's only part of the problem. Glass is brittle and will flake off, and ground glass is a well-known friction-increasing additive. And either way it's too hard, increasing the risk of impact ignition.

The steel balls were charged into the stainless steel pot while the alumina balls or glass balls were charged into the alumina pot. The slurry was put into the mill to fill in the space in the ball bed. Grinding time was varied from 5 to 60 min and N/N C was varied between 1.0 and 3.6. Other experimental conditions are given in Table 4.
