A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The ATOX coal mill is suited for various installation types, whether inert or noninert, and direct or indirect firing systems. An inert system designed for indirect firing is the most common solution for cement plants. Equipped with the highefficiency RAKM dynamic separator, the ATOX coal mill will grind any type of coal to the required
