Calculator
Enter your product’s bulk density along with either your target throughput or a conveyor size to calculate the appropriate capacity. The calculator will either convert your required rate of conveyance into volumetric flow (ft³/hr) and recommend a Chain-Vey diameter, or estimate the maximum throughput a selected conveyor size can handle for your product.
If you enter a bulk density of 40 lb/ft³ and a throughput of 50,000 lb/hr, the calculator will convert that to 1,250 ft³/hr and recommend a 6″ Chain-Vey system. If instead you select a 6″ conveyor and enter the same bulk density, the calculator will reverse the calculation and show that the system can handle up to 56,000 lb/hr. This allows you to either size a new system based on your required throughput or quickly evaluate the capacity of a specific conveyor size for your product.

Flexible Tubular Conveyor Designs
All of our tubular conveyor systems are robust, sanitary, gentle, and quiet. The robust, low-friction discs are designed for lower maintenance costs and energy consumption. Chain-Vey offers both standard Quiet Pucks and High-Efficiency Pucks for special applications.
Frequently Asked Questions
Could I run the tubular conveyor at full speed all the time?
Yes. But it’s inadvisable for two reasons:
1. It creates unnecessary wear on internal components.
2. When planning out system capacity, do not let your conveyor become a choke point. Give yourself some headroom as capacity grows. A loosely applied rule is matching a customer’s maximum desired rate with a conveyor’s rate at 80% speed and 80% pocket fill.
Are Chain-Veys’ widths measured by inner pipe diameters or outer tubular diameters?
All 4″, 5″, and 6″ Chain-Veys are fabricated with pipes, whose diameters are measured from inside the pipe. Technically this means Chain-Veys could be referred to as pipe conveyors instead of tubular conveyors. The benefit is that 4″ Chain-Veys actually have 4″ wide diameters (referred to as “nominal pipe size”) inside their pipes. Other competitors who make their conveyors with tubes may claim a 4″ diameter which, while technically true, means the usable diameter is really only 3.5 or 3.75″ wide. The obvious difference is that, all else equal, Chain-Veys will have more volume to convey compared to non-pipe tubular conveyors.
One exception is that Chain-Vey’s 3″ diameter system is fabricated with tubes, whose diameters are measured from outer tube diameter.
How does one clean a tubular conveyor?
Our tubular conveyors are self-cleaning because they all have at least one wiper disc that continually wipes small fragments or residual product through the conveyor until it leaves through one of the discharge points. Getting inside turnarounds for periodic cleaning is easy with tool-less entry.
