capacity improvement of coal mills

Jameson cell

The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for ...

OhioMInes

By the late 1800's, mechanization and improvement of mining methods led to a steady increase in the production of Ohio coal. Much coal was used to make coke to fuel the many steel mills that dotted the upper Ohio River valley. In 1872, Ohio mines produced more than five million tons of coal. Production increased to ten million tons by 1886.
