• Why Propellant Materials Are Difficult to Handle

  Propellant and powder materials behave differently from most industrial bulk solids, and the stakes of handling errors are higher:

  • Fine, granular propellants are prone to bridging and inconsistent discharge
  • Grain size and blend consistency directly affect burn rate and ballistic performance
  • Friction, impact, and static discharge are genuine safety concerns, not just quality issues
  • Dosing accuracy by weight is critical to consistent, safe performance

  Combustible powders and metal dusts are among the most serious explosion hazards in this industry. Many munitions and ammunition facilities are classified hazardous locations, and equipment must be rated for safe operation wherever these materials are present. MARTIN® offers ATEX-certified and explosion-proof vibration equipment across our product line.

• Munitions Materials Handled

  Our equipment is designed to safely and efficiently handle a range of granular and powder materials in munitions manufacturing:

  • Single-, double-, and triple-base propellants
  • Granular and flake powders
  • Black powder and powder substitutes
  • Blended propellant formulations
  • Bulk powder intermediates
• Where Our Products Fit in the Supply Chain

  Vibration plays a role at multiple points in munitions material handling, not just one stage of the process.

  Intake & Storage Powder transfer and hopper discharge as propellant materials enter the facility, including bin and silo discharge systems that reduce bridging at the point of receiving.

  Metering & Dosing Propellant and energetic material handling for precise, repeatable charge weights during load assembly.

  Screening & Transfer Bulk material flow promotion and screening and separation processes that maintain consistent flow between process steps.

  Packaging & Filling Packaging and filling operations, including compacting and settling finished ammunition in boxes and containers prior to sealing and shipment.

• End Products Supported

  Our equipment supports accurate metering, dosing, and transfer in support of:

  • Small arms ammunition
  • Cartridge and shell loading
  • Propellant charge assembly
  • Reloading and remanufacturing operations
• Operational Benefits for Munitions Manufacturers

  We help munitions manufacturers improve material flow, protect employees, and maintain strict process control.

  • Improved material flow with reduced bridging
  • Increased process reliability and throughput
  • Consistent, repeatable dosing accuracy
  • Reduced manual intervention and safety risks near hazardous materials
  • Solutions available for hazardous-area applications, including ATEX-certified equipment
  • Easier compliance with facility safety standards
  • Consistent settling and compaction of ammunition in shipping packaging
