Sinfimasa Screw Conveyors: reliable and robust solutions for bulk solid transport
Design of Screw Conveyors
Sinfimasa specializes in the design and manufacturing of screw conveyors for a wide range of industrial applications. Our screw conveyors are custom-designed for each project, ensuring robustness, reliability, and safety. We use high-quality materials and components from leading international brands like SEW and SKF, ensuring low maintenance costs and optimal performance in the transport of bulk solids.
In our technical office, we tailor each screw conveyor to the project requirements and the material to be conveyed. We manufacture bodies, augers, and shafts from a broad selection of steels such as Hardox, carbon steel, and stainless steel (AISI 304/316L), as well as other materials according to customer specifications. Additionally, our conveyors comply with standards like FDA and ATEX to ensure safety and regulatory compliance in sensitive sectors such as food, pharmaceutical, and chemical industries.
Tubular Screw Conveyors for extracting and transporting solids
Tubular screw conveyors are ideal for extracting and transporting materials in controlled environments like silos. Their robust and sealed design makes them suitable for handling fine and abrasive materials such as cement and sand. These conveyors can operate with vertical inclines and are made from wear-resistant materials to withstand demanding conditions.
Auger Conveyors in trough design for efficient transport and easy maintenance
Trough screw conveyors are designed for the efficient transport of bulk materials. With a constant pitch flighting, they offer high transport capacity with low energy consumption. They are ideal for non-abrasive products and stand out for their easy access for cleaning and maintenance, making them especially useful for materials prone to clumping.
Shaftless Screw Conveyors for viscous and fibrous materials
Shaftless screw conveyors are perfect for transporting viscous, fibrous, or irregular materials. These screw conveyors are designed to handle products that tend to stick, such as variable-density sludge. They use spirals over a friction bed to ensure efficient, continuous operation with minimal maintenance, making them reliable for applications in urban and industrial environments, wastewater treatment, and composting.
These specialized screw conveyor solutions allow Sinfimasa to offer equipment tailored to the specific demands of each industry, ensuring efficiency, reliability, and low maintenance across all operations.

Our technical office dimensions each conveyor and adapts it to the customers’ and engineering companies’ project according to specifications, the solid to be transported and its specifications. A screw conveyor for every need.
For example, we design and manufacture screw conveyors with anti-wear materials and slow working speeds to avoid premature wear when working with demanding aggregates and minerals. We also include ATEX certification for working in classified hazardous and explosive areas, or coreless screw conveyors for slurries of varying density and moisture that tend to stick together. The bodies can be either trough or tubular and of any type of steel and finish to meet the specifications of each particular customer.
The bodies, threads or propellers and shafts are manufactured with all the qualities of steel available on the market: Hardox, carbon steel, AISI-304/316L stainless steel and super stainless steel, etc.
For sectors such as the food, pharmaceutical and chemical industries, we design and manufacture screw conveyors for fine dosing and high production, with a hygienic design in compliance with FDA requirements. We also equip and certify them according to ATEX regulations for dust and gas.
All our screw conveyors can be fitted with filling, speed and overload sensors. Depending on the material to be handled, we equip them with specific components such as polyethylene bottoms, sliding plates, carbon steels, anti-wear and stainless steel.
The most common finishes include pickling, passivation, galvanising and zinc plating, as well as painting according to the environment in which the equipment is to operate (primer and polyurethane finish, with the RAL to be chosen by the customer).
Sinfimasa designs and manufactures screw conveyors specifically for each project, providing users with performance, reliability and safety. A screw conveyor for any bulk solid, including yours. We design and manufacture with the utmost rigour and our experience in various countries on five continents is our guarantee. Consult us about your project and we will provide you with a solution.
