Anderson Dahlen’s customizable screw conveyors offer companies across many industries efficiency, safety, reliability, and ease of use. A sanitary screw feeder with easy-open, dust-tight doors and moving parts that swing out of the way for easy sanitation access is necessary for food processors. In the chemical industry, screw conveyors must maintain specific pressure ratings when handling hazardous materials. Our screw conveyors can be engineered to be vapor-tight, ensuring internal pressure remains high and material doesn’t leak. They are available in a range of auger, shaft, and flighting configurations to meet your specific needs for moving bulky solids, powders, or viscous slurries
Our custom screw conveyors are designed to move a wide range of bulk materials, including powders, bulky solids, wet ingredients, dry ingredients, viscous slurries, and sludge-like materials. Conveyor configurations are selected based on the material characteristics and application requirements.
Some of our screw conveyors are constructed as shaftless screw conveyors, designed without a center pipe. This design is well suited for thick, sludge-like, or biosolid materials that would otherwise wrap around a center shaft, making it a common choice for wastewater treatment and other demanding material handling applications.
Yes. Our screw conveyors are customized with different screw lengths, diameters, inlet and outlet configurations, screw types, shaft seals, hanger bearings, motors, interior finishes, and easy-access door locations to support specific processing and material handling requirements.
Screw conveyors use a rotating screw to push bulk materials through a tube or trough, while drag conveyors pull materials using a chain and flight system. Screw conveyors are better for tight spaces and lower budgets, while drag conveyors are best for fragile materials.
Yes. Food processors rely on our sanitary screw feeders for easy-open dust-tight doors, FDA-approved door gaskets, rapid-cleaning product contact surfaces, and protected operator access points that meet sanitation and product handling requirements.
Yes. Screw conveyors can be designed and installed horizontally, vertically, or at an angle depending on the facility size, layout, material flow requirements, and process configuration. Vertical installations often incorporate bucket elevators to move materials upward efficiently. This allows flexibility when installing in a congested manufacturing space.
Easy-access screw conveyors simplify cleaning, maintenance, and product changeovers. Features such as swing-out access doors, removable covers, and rapid-cleaning surfaces improve accessibility while minimizing downtime during sanitation procedures.
Yes. Screw conveyors can also be designed for use as mixers, breaking up large materials, heating, cooling, drying, and controlling material flow during processing operations.
Yes. Our screw conveyors can be engineered to be vapor-tight for chemical processing and other applications involving hazardous materials, ensuring controlled internal pressure and helping prevent material leakage during operation.
