Hydraulic comparison test pumps have a screw press and a built-in pump to generate high pressures appropriate for high-volume applications. They compare the pressure gauge being calibrated against a master test gauge to verify accuracy. . Electronic deadweight testers function as a field tester or in-situ, offering complete calibration .

Screw conveyors are widely used in various industries for the transportation of bulk materials. Properly sizing a screw conveyor is crucial to ensure efficient and reliable operation. In this article, we will discuss the key factors to consider when sizing a screw conveyor, including bulk material characteristics, trough loading, and screw conveyor design. We will also provide a screw conveyor size chart, parts diagram, schematic diagram, design diagram, catalogue, and data sheet to help you in the sizing process.

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).

Bulk Material Characteristics

Before sizing a screw conveyor, it is essential to understand the characteristics of the bulk material being transported. The two most critical factors to consider are the maximum particle size and bulk density of the material.

- **Maximum Particle Size (in.):** This refers to the largest particle size present in the bulk material. It is crucial to know the maximum particle size as it will impact the size and design of the screw conveyor.

- **Bulk Density (lbs/ft³):** The bulk density of the material is the mass per unit volume. It is essential for determining the capacity and power requirements of the screw conveyor.

Trough Loading

Trough loading, also known as the fill level, is the percentage of the trough filled with bulk material. It is crucial to maintain an optimal trough loading to ensure efficient material transport and prevent overloading of the conveyor.

Screw Conveyor Size Chart

Here is a sample screw conveyor size chart to provide a general guideline for sizing based on material characteristics:

| Maximum Particle Size (in.) | Bulk Density (lbs/ft³) | Screw Conveyor Diameter (in.) |

|-----------------------------|-----------------------|-------------------------------|

| 1 | 30 | 6 |

| 2 | 40 | 8 |

| 3 | 50 | 10 |

Please note that this is just a simplified example, and actual sizing may vary based on specific application requirements.
