Nine PW product lines for storing, blending & homogenizing, discharging, and filtering – in aluminum and stainless steel, designed to work together and supplied by one manufacturer.
Product Lines
Each line covers one task in bulk solids handling – and all are designed to work together.
PW StoreLine storage silo systems are designed for most commonly used bulk solids. Combined with a comprehensive range of accessories, they handle virtually any bulk storage application efficiently and cost-effectively.
Storage Silos
A wide range of silo sizes and diameters allows a flexible, cost-effective configuration to match your required storage capacity. Our designs cover nearly all free-flowing, low-cohesion, granular, and powdered bulk solids – based on concentric mass-flow discharge without asymmetric flow zones.
PW BlendLine silos prevent horizontal layers of varying quality and deliver reliable product quality. Whether equipped with PipeBlend, CentralPipeBlend, ConeBlend, or ScrewBlend: each configuration is designed to deliver consistent results with high efficiency.
Pipe Blender
The blending pipes run along the silo wall. Specially designed inlet openings promote pre-blending as material enters the pipes. This creates different flow velocities across the entire cross-section, homogenizing the product in the blending chamber at the silo outlet.
Granules and free-flowing bulk solids.
Central Pipe Blender
The large-diameter central blending pipe handles a wide range of bulk solids, including powders and materials with poor flowability. Multiple inlet zones along the pipe draw in material from different levels of the silo. This cross-blending, combined with varying flow velocities and flow patterns inside the pipe, further improves product homogeneity.
Powders and bulk solids with poor flowability.
Cone Blender
A flanged or welded blending insert integrated into the silo cone ensures even distribution of the bulk solid. As the material flows toward the outlet, it passes through different flow zones. Varying flow velocities create different residence times within the silo, further improving homogeneity.
Fast, simple retrofits of existing silos thanks to its compact design.
Screw Blender
Material is continuously fed from the cone into a vertical, center-mounted blending screw and conveyed upward. At the top of the screw, it falls back into the silo by gravity, creating a continuous blending cycle. The screw is driven by a gear motor mounted at the center of the silo roof.
