Capabilities

Bulk Material Testing

Comprehensive laboratory and on-site testing of powders and bulk solids to obtain accurate flow and particle properties, avoiding guesswork in equipment design.

  • Flow Properties Testing

    Measuring cohesive strength, wall friction, internal friction, compressibility, permeability, angle of repose, tap density, and chute angles to evaluate powder flowability.

  • Segregation Testing

    Determining segregation behavior such as sifting, fluidization, and sieve cut potency to understand and prevent particle separation.

  • Pneumatic Conveying Testing

    Evaluating conveying characteristics, minimum conveying velocity, particle attrition, abrasive wear, and line coating under simulated vacuum or positive pressure modes.

  • Caking and Attrition Testing

    Assessing powder caking tendencies over time at rest and evaluating particle attrition or friability under handling conditions.

  • Fluidization & Gas Assisted Discharge

    Testing the fluidization properties of powders and behavior under gas-assisted discharge environments.

  • On-Site Materials Testing

    Bringing precision shear testing and segregation testers to production plants, mines, or R&D facilities to test hazardous, toxic, or unstable materials.

  • Tester Supply

    Supplying material-sparing testers and laboratory instruments to measure flowability and segregation mechanisms.

Engineering and Analysis

Functional and structural design services for bulk solids storage, handling, and transfer systems, supported by advanced numerical modeling.

  • Conceptual & Functional Engineering

    Developing functional designs for silos, hoppers, feeders, transfer chutes, and stockpiles based on measured flow properties.

  • Structural & Mechanical Engineering

    Providing detailed structural and mechanical design to support reliable operations and maintain structural integrity of storage units.

  • Discrete Element Method (DEM) Modeling

    Applying advanced DEM simulation to model mixing, blending, segregation, and chute flow behaviors.

  • Solids-Induced Loads Analysis

    Calculating flow-induced and static loads exerted by bulk solids on silo and vessel walls to prevent structural failures.

  • Stockpile Stability & Drainage Analysis

    Evaluating stockpile drainage, seepage, and structural stability of large-scale bulk storage piles.

Equipment Supply

Design and supply of custom bulk material handling equipment built to prevent flow obstructions and ensure uniform discharge.

  • Mass Flow Silos, Bins, and Hoppers

    Custom design of bins and hoppers configured for mass flow or funnel flow to resolve poor flow issues.

  • Mass Flow Feeders

    Supply of feeders designed to withdraw material uniformly across the entire outlet of a silo or hopper.

  • Transfer Chutes

    Engineering and supplying custom transfer chutes to minimize dusting, spillage, and abrasive wear.

  • Custom Equipment Supply

    Manufacturing and supplying tailored mechanical equipment for specialized material processing and feeding.

Consulting and Support

Field services, training, and specialized consulting to troubleshoot, optimize, and support bulk material handling operations.

  • Site Visits and Troubleshooting

    Conducting on-site evaluations to solve or prevent poor flow, process non-uniformity, and equipment failures.

  • Education & Training

    Providing specialized courses, webinars, and technical training on bulk solids flow, pneumatic conveying, and handling design.

  • Expert Witness & Litigation Support

    Offering professional forensic engineering, failure investigation, and expert witness services for silo and handling equipment litigation.

  • Silo & Equipment Failure Investigation

    Analyzing structural or operational failures in storage systems to identify root causes and recommend remediation.
