Why is it necessary to grind ash and slag in the ash handling process?

Grind ash and slag during the ash handling process primarily to facilitate easier handling and transport. When ash and slag are produced from combustion processes, they typically have a coarse and bulky texture, which can create challenges in conveying them effectively through pneumatic or mechanical systems.

By grinding these materials down to a finer consistency, their volume reduces, making them less cumbersome to move. A finer particle size also enhances the flow characteristics of the ash and slag, allowing for smoother transport through pipes and various handling equipment. This reduction in size helps in preventing blockages and allows for more uniform distribution when the materials are loaded or transported to disposal or recycling sites.

Additionally, smaller particles can settle more easily and efficiently, minimizing dust generation during handling, which is crucial for maintaining safety and cleanliness in the work environment. Therefore, the necessity of grinding ash and slag mainly stems from the need to streamline the ash handling process, ensuring that it is both efficient and manageable.
