Screw conveyors are widely used in various industries for the efficient handling of bulk materials. One crucial aspect of designing and operating a screw conveyor is determining its capacity to ensure optimal performance. The capacity of a screw conveyor is influenced by several factors, including the bulk material properties, trough loading, and conveyor design. In this article, we will discuss how to find screw conveyor capacity, including the use of capacity charts, online calculators, formulas, and more.
Capacity is defined as the weight or volume per hour of a bulk material that can be safely and feasibly conveyed using a screw conveyor. Screw conveyor diameter is determined by multiple factors including capacity. Calculate required capacity in cubic feet per hour (ft 3 /hr).
Screw Conveyor Capacity Chart
A screw conveyor capacity chart is a useful tool that provides a quick reference for determining the capacity of a screw conveyor based on the bulk material properties. These charts typically list different screw conveyor sizes and configurations along with corresponding capacity values for various bulk material types. By referring to a capacity chart, engineers and operators can easily select the appropriate screw conveyor size and design for their specific application.
Screw Conveyor Capacity Calculation Online
In today's digital age, online calculators have become invaluable tools for engineers and designers. Several websites offer online screw conveyor capacity calculators that allow users to input parameters such as bulk material properties, trough loading, screw diameter, pitch, and speed to quickly calculate the conveyor's capacity. These online calculators provide a convenient and efficient way to determine the capacity of a screw conveyor without the need for manual calculations.
Screw Conveyor Capacity Formula
For those who prefer to calculate screw conveyor capacity manually, there are established formulas that can be used to determine the capacity based on the conveyor's geometry and bulk material properties. One common formula for calculating screw conveyor capacity is the following:
\[ Q = \frac{πD^2}{4} \times L \times S \times C \]
Where:
- \( Q \) = Capacity of the screw conveyor (ft³/hr)
- \( D \) = Diameter of the screw conveyor (inches)
- \( L \) = Length of the screw conveyor (feet)
- \( S \) = Screw speed (RPM)
- \( C \) = Capacity factor (see manufacturer's data or engineering standards)
By using this formula and inputting the appropriate values, one can calculate the capacity of a screw conveyor accurately.
Schematic Diagram of Screw Conveyor
A schematic diagram of a screw conveyor illustrates the various components and dimensions of the conveyor, including the screw diameter, pitch, trough design, motor location, and inlet/outlet configurations. Understanding the schematic diagram is essential for visualizing how the screw conveyor operates and how the bulk material is transported along the conveyor.
Martin Screw Conveyor Catalog
Martin Sprocket & Gear, a leading manufacturer of screw conveyors, offers a comprehensive catalog that includes detailed information on their screw conveyor products. The Martin Screw Conveyor Catalog provides specifications, capacity charts, installation guidelines, and maintenance recommendations for their screw conveyor models. Engineers and operators can refer to the Martin catalog to select the appropriate screw conveyor for their application and access valuable technical information.
Screw Conveyor Speed Calculation
The speed of a screw conveyor is a critical factor that influences its capacity and performance. The speed of the screw conveyor is typically calculated based on the desired material flow rate, screw diameter, and pitch. By using the following formula, one can calculate the speed of a screw conveyor:
\[ Speed = \frac{Q}{πD^2/4} \]
Where:
- \( Speed \) = Screw speed (RPM)
- \( Q \) = Material flow rate (ft³/hr)
- \( D \) = Diameter of the screw conveyor (inches)

A pump stage is defined as that portion of a centrifugal pump consisting of one impeller and its associated components. Most centrifugal pumps are single-stage pumps, containing only one impeller. A pump containing seven impellers within a single casing would be referred to as a seven-stage pump or, or generally, as a multi-stage pump.
