Bulk Solid Material Handling

Wide range of solutions for storing, handling and dosing powders, granules and liquids.

  • For plastics, chemical, food, pharmaceutical and cement industries
  • Consistently maintain flow rates of poor flowing materials
  • Compact design

Dosing Units for Powder and Liquid

  • Suitable for compounds, recycled materials, powders, granules, flake, pellets and fibers.
  • For flow rates from a few grams per minute up to 8 tons per hour.
  • Designed to dose twin screw and single screw extruders with maximum accuracy, consistency and repeatability.

Control System Choices

  • Volumetric
  • Gravimetric batch
  • Gravimetric continuous (loss-in-weight).

Conveying of Bulk Materials

Dilute Phase Pneumatic Conveying of Bulk Materials

  • Flow rates can reach up to 30 tons/h. 
  • Ideal for conveying speeds in the range of 20-30 m/s.
  • Suited to powders, granules or regrind. 
  • Options for positive pressure (pressure), negative pressure (vacuum) and mixed pressure (vacuum and pressure).

Dense Phase Pneumatic Conveying of Bulk Materials

  • Flow rates can reach up to 100 tons/h
  • Ideal for use with conveying speeds of 5 -10 m/s. 
  • Suited to fragile, abrasive, pre-mixed product, or those conveyed over long distances. 

Mechanic Conveying 

  • Mechanical feeding systems for refill hoppers.
  • For PVC mixing plants, a belt for pre-weighed additive bags can be provided. 

Storage of Bulk Materials

Maguire + Plantech-CST provide solutions for storing and handling multiple raw materials and additives used in plastics processing, chemical plants, food production plants, pre-mixed materials such as cement, and ecology.

Storage Solutions

  • Silo choices dependent on volume.
  • Aluminum, stainless steel, carbon steel and Trevira textile silos to suit the specific type of product to be stored.
  • Emptying bags / stations and filling systems for additives and masterbatch.

Filtration and Extraction of Bulk Materials


  • Separates dust from air. Dusty material is held back by the filter.
  • Suitable for use in pneumatic conveying system – both vacuum and pressure.
  • Easy cleaning via large side door. 


  • Range of bin activators to promote the flow of poor flowing materials from hoppers – minimizing bridging. 
  • Flat bottom extractor for use with dusty materials. Available for diameters from 600mm up to 1200mm.
  • Multi screw extractor for the extraction and handling of powders and regrind material – move material without dust leakage. 
  • Compact lump breaker for materials that clump together easily. Easy access for viewing the process via front door.
