Resolve an instance where the crusher fails to feed.

Check 1: Haul Infinity > Network > Select the source and destination > Right Click > Show Return Route.

Check a valid haul route exists.

Check 2: Schedule > Calendar > Crushers > Capacity vs. Actual.

Confirm crusher capacity exists.

Check 3: Schedule > Calendar > Constraints > Capacity vs. Actual.

Check 4: Reporting > Pivot Tables > Source Parcel vs. Destination Top vs. Destination Logic Rule

Confirm that ore is mined and evaluated correctly.

If not enough ore is mined, consider mining tonnes from different pits or benches.

Check 5: Setup > Destination Logic > Destination Rule.

Confirm that the ore destination rule lists the crusher as a destination.

Check 6: (Product Optimised) Schedule > Calendar > Product Specifications > Grade/Blend limits.

Look for zeroed or contradicting grade limits, such as Minimum Fe greater than Maximum Fe.
Look for impossible blend targets, such as a Minimum Feed Ratio of a material that isn't mined or stocked.

Confirm that product specifications are present and correct.

Check 7: (Product Optimised) Schedule > Calendar > Product Specifications > Penalties.

Check for penalties or negative cash flows.

The optimiser may refuse to feed the crusher if the net grade penalty outweighs the crusher cash flow.

Net grade penalty =  (Content Deviation Penalty) * (actual grade - target grade) * 1000

Check 8: (Truck Constrained) Schedule > Calendar > Stockpiles > Reclaim Target.

Check 9: (Truck Constrained) Schedule > Setup > Stockpiles > Finger Pile properties.

If a stockpile is First In First Out (FIFO) or Last In First Out (LIFO), then it cannot be reclaimed until it hits the Finger Pile Size (unless you tick Finish Pile at Period End).

Check 10: Setup > Map Fields.
