- Typical throughput
- Throughput for this class of equipment typically ranges from a few hundred kilograms per hour to several tonnes per hour, depending on screw diameter, pitch, and motor speed.
- Power supply
- Units of this type commonly require a 3-phase electrical supply, typically 400V, 50Hz, with motor power commonly in the 1.5 kW to 7.5 kW range for industrial applications.
- Material of construction
- For food processing applications, screw conveyors are almost exclusively constructed from stainless steel (e.g., 304 or 316 grade) to meet hygiene standards.
- Screw diameter
- Common screw diameters for food-grade conveyors range from 150mm to 400mm, influencing capacity and the size of material handled.
- Conveyor length
- Screw conveyors can vary significantly in length, from short transfer units of 1-2 metres to longer systems exceeding 10 metres, often customised to facility layouts.
- Hopper capacity
- Integrated hoppers on screw conveyors typically range from 25 kg to 250 kg, designed to provide a buffer for continuous feeding.
- Cleaning and maintenance
- Designs commonly incorporate features for ease of cleaning, such as quick-release covers, split troughs, or removable screws, crucial for food safety and preventing cross-contamination.
