8 critical factors that impact the design and price

The throughput of a screw conveyor is defined by its size, running speed and loading. Throughput therefore has a dominant impact on cost. Higher throughputs necessitate the use of larger diameter machines and more powerful motors, however the relationship between cost and size is not linear a machine with double the throughput would be expected to be around 30 60% in price.
