How do you calculate loader feed rate?

Multiply bucket cycles per hour by tons per bucket for gross feed, then multiply by operating efficiency. At 42 cycles/hr and 5.5 tons/bucket, gross is 231 tons/hr; the preset's efficiency yields an effective rate of 763.64 in the example units.

What is a good loader cycle time at an asphalt plant?

A typical V-cycle for a wheel loader feeding cold-feed bins runs 25-35 seconds, or roughly 100-140 cycles per hour at full effort. Effective rates are lower once you derate for repositioning, waiting, and breaks.

How many tons can a wheel loader move per hour?

It depends on bucket size and cycle time. A loader with a 5.5-ton effective bucket payload cycling steadily can move several hundred tons per hour gross, before efficiency derating for real-shift interruptions.

What is loader operating efficiency?

It is the fraction of clock time the loader is actually producing useful cycles, accounting for repositioning, waiting on trucks, fuel and breaks, and pile cleanup. Plug your real shop number; it is the lever that turns gross feed into a believable rate.

Why is my loader starving the plant?

Effective feed has fallen below plant tonnage demand. Either cycles per hour dropped (longer travel, congested pad), bucket payload fell (poor fill, wet sticky material), or efficiency sagged from waiting and repositioning. This tool isolates which one.

How do I raise loader throughput without a bigger machine?

Shorten the cycle by restacking piles closer to the bins, improve bucket fill technique, and cut idle waiting. Each lifts a different term in the formula, and small gains in efficiency move the effective rate noticeably.

Aggregate Loader Cycle Rate Calculator

Aggregate Loader Cycle Rate tells a plant manager how many tons per hour a wheel loader can actually feed the cold-feed bins or stockpile, after derating raw cycle speed for the real-world delays that eat a shift. Plant operators and superintendents use it to confirm the loader can keep up with mix production, to right-size loader fleet decisions, and to spot when an operator or machine is underperforming. A drum or batch plant starves the moment loader feed drops below production demand, so this rate is the upstream constraint that quietly governs plant output. Knowing the effective tons per hour lets you match loader capacity to the plant's hourly tonnage with confidence.

What this calculator does

Calculate effective loader tons per hour from bucket cycles, tons per bucket, and operating efficiency.
a loader operator or plant manager needs to verify stockpile-to-bin feed capacity for aggregate or RAP
It computes effective loader feed in tons per hour by multiplying bucket cycles per hour by tons per bucket to get gross feed, then derating by operating efficiency.

Formula used

Gross loader feed rate = loader bucket cycles × aggregate per bucket
Effective loader feed rate = gross loader feed rate × loader operating efficiency

Inputs explained

Loader bucket cycles per hour:
Aggregate per bucket:
Loader operating efficiency:

How to use the result

Use it when checking whether a loader can keep a plant fed, sizing a loader for a new plant, or benchmarking operator productivity against a target.
It assumes a steady cycle and consistent bucket payload; in practice payload varies with material moisture, pile face condition, and bucket fill factor, so spot-check against truck-scale tons when you can.
