Silo Solutions by Bulk Material

Every bulk solid behaves differently. We design storage, blending & homogenizing, and discharge around the properties of your material – for nearly all free-flowing, low-cohesion, granular, and powdered bulk solids.

Designed Around Your Material

Why your bulk material comes first

How a bulk solid flows, settles, and blends determines how a silo has to be designed. That is why every solution starts with your material: bulk material analysis and time consolidation testing provide the basis for a reliable design.

PW StoreLine silos are based on concentric mass-flow discharge without asymmetric flow zones. For poorly flowing bulk solids, PW FlowLine adds tailored discharge solutions – and PW BlendLine provides blending & homogenizing for everything from free-flowing pellets to cohesive powders.

Bulk Materials

Solutions for the materials you handle

Select your bulk material to see what matters in storage and handling – and which of our solutions fit.

Plastics

Plastic Pellets & Masterbatches

Pellets must keep their quality and functionality until they are processed. Our silos integrate into your production layout and keep material flowing from storage to the processing machine.

What Matters

  • Cost-effective bulk storage with aluminum, stainless steel, and blending silos
  • Corrosion-resistant, durable, and low-maintenance construction
  • Custom-engineered PW silo discharge systems for reliable material flow and seamless production integration

Plastics · Chemical

Powder Modifiers & Titanium Dioxide

Powder modifiers and titanium dioxide enhance the properties of plastics. They need to stay available at consistent quality – and powders with poor flowability need the right discharge technology.

What Matters

  • Proven expertise in powder storage and handling
  • Custom PW discharge systems for reliable powder flow
  • Easy-to-clean aluminum and stainless steel to minimize contamination

Food

Flour, Sugar, Starch & More

Flour, sugar, starch, glucose, cocoa, and proteins must be stored so that their quality, taste, and functionality are preserved. Aluminum and stainless steel keep coatings out of contact with your product.

What Matters

  • Custom-engineered storage and blending silos
  • No coating-related product contamination
  • Food-grade materials with excellent cleanability

Recycling

Recycled Plastics

Regrind, flakes, and agglomerates vary from batch to batch and often carry odors. Deodorizing silos reduce odors, and blending & homogenizing evens out quality before processing.

What Matters

  • Effective odor reduction and material homogenization
  • Custom PW discharge systems for consistent, reliable material flow
  • Engineered to minimize material bridging and flow disruptions
