Practical 1 : Ball Milling | TF Lab 1

 · In roller mills, the principle of attrition is used where material is sheared as it passes through a gap and is transferred from slower roll to a faster roll, and is removed by a scraper. In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is

Pulp and Paper Manufacturing at Bowater Pulp & Paper

These refiners are powered by 30,000-horsepower motors which together draw about 90 megawatts of power (enough electricity to power a city of 80,000 people!). The pulp is then refined in two other stages and screened prior to storage in a latency tank. This improves the flexibility and strength of the fibre before it is pumped to the paper machine blend chest.
