How do you calculate net sort line capacity per shift?

Multiply tons per cycle by cycles per shift for gross capacity, then multiply by availability and first-pass yield. With 0.25 t/cycle, 480 cycles, 85% availability, and 92% yield, gross is 120 t/shift and net is 93.84 t/shift.

What is the capacity gap on a MRF sort line?

It is the difference between gross and net throughput. In the example, 120 gross drops to 93.84 net: 18 tons lost to availability and 8.16 tons lost to first-pass yield, a 26.16-ton gap per shift.

What is a good availability for a waste sort line?

Well-run single-stream lines hit 85-92% availability; below 80% you are losing too much to jams and changeovers. The example uses 85%, which costs 18 tons per shift on its own.

Why does first-pass yield matter so much?

Material missing the first pass either becomes residue or must recirculate, both of which cut effective throughput. At 92% yield the example loses 8.16 tons per shift even before considering recirculation load.

How do I close the capacity gap?

Attack availability first since it is the larger loss here (18 vs 8.16 tons): reduce jams with better pre-shred sizing and add buffer surge. Then tune optical and screen settings to lift first-pass yield.

Is net capacity the same as throughput rating?

No. The nameplate rating is closer to the gross 120 t/shift. Net capacity of 93.84 t/shift is what the line actually recovers once downtime and yield losses are counted, and it is the number to contract against.

Municipal Waste Sorting Equipment calculator

Sort Line Capacity Gap Calculator

Capacity Gap calculates the net tonnage a municipal sort line actually recovers per shift after availability downtime and first-pass yield losses are stripped from its gross rate. Plant managers and MRF designers use it to size a line against an incoming tonnage commitment and to expose the gap between nameplate and real throughput. A sort line rarely delivers its gross number: jams, blockages, and changeovers eat availability, and material that misses the first pass falls to residue or recirculation. This calculator turns those two loss factors into tons you can plan around.

What this calculator does

Estimate the realistic tons per shift a sort line can deliver so you can see the gap against contracted inbound tonnage.
Use it when a contract is up for bid or inbound tonnage is growing and you need to know whether the existing line has room before adding capex.
It multiplies tons per cycle by cycles per shift for gross capacity, then derates by availability and first-pass yield to give net recovered tons per shift.

Formula used

Gross sort line capacity = tons per cycle x available cycles per shift
Net sort line capacity = gross sort line capacity x line availability x first-pass recovery yield

Inputs explained

Tons fed per cycle on the bottleneck line:
Available sort cycles per shift:
Sort-line availability:
First-pass recovery yield:

How to use the result

Use it when sizing a sort line against a tonnage contract, or diagnosing why actual recovery falls short of the rated rate.
It models availability and yield as single shift-average percentages; it does not capture composition swings between morning and evening loads that shift the real yield.
