Fly ash ball mill

The fly ash ball mill enables the secondary use of fly ash and reduces the pollution caused by fly ash. The fly ash fines processed by the fly ash ball mill have an average particle size and improved surface activity.

Ball load: 1.5-110t

Capacity: 0.65-90t/h

Application:

Widely used in concrete additives, hollow brick, ceramics, and backfill materials for construction projects.

Fly ash ball mill features

Good economic efficiency

The fly ash ball mill can superfinely grind the raw ash or the sorted coarse ash mixture to make it have a certain hydraulic activity, and produce the blended superfine ash that can be used to prepare high-performance concrete. The purpose of full utilization of coal ash is to create greater economic benefits.

High fly ash utilization efficiency

The ground coal ash can be sorted. After sorting, the coarse ash is returned to the fly ash ball mill for ultra-fine grinding to produce an admixture capable of preparing high-performance concrete, which greatly improves the economy of comprehensive utilization of fly ash Benefit, can realize all comprehensive utilization of fly ash.

Simple process

A fly ash ball mill adopts an open circuit system. After the coarse ash that enters the mill is ground in the mill, the discharged fly ash directly meets the grade ash fineness requirement (adjustable), without the need for screening or sorting.

High grinding fineness

The special ball mill for fly ash produced by our company completely adopts the particulate grinding body, which directly enters the grinding conditions for grinding, so it can smoothly grind the particles of 45-150μm to below 45μm.

Fly ash ball mill working principle

Choose according to the particle size of fly ash. The material is loaded into the cylinder by the hollow shaft at the feed end of the mill. When the cylinder of the ball mill rotates, the grinding body will stick to the nearby cylinder lining due to inertia, centrifugal force and friction. The board is taken away by the cylinder, and when it is brought to a certain height, it is thrown off due to its own gravity. The falling grinding body crushes the material in the cylinder like a projectile.

The material enters the mill cabin uniformly through the feeding device through the feeding hollow shaft spirally and uniformly. The cabin has a step liner or a corrugated liner with steel balls of different specifications. The rotation of the cylinder generates centrifugal force to bring the steel balls to a certain height and then fall down, It has a heavy blow and grinding effect on the material.

After the material reaches the rough grinding in the warehouse, it enters the warehouse through the single-layer partition board. The warehouse is lined with flat liners and steel balls to further grind the materials. The powder is discharged through the unloading grate to complete the grinding operation.
