International Mobile Mixer features

Aggregate Bin

  • VMMB approved mixer meeting ACI 304. 6R and AASHTO M-241 and ASTMC-685 Standards with full length aggregate trough Provide square strike-off of sand and stone ensuring an accurate mix.
  • Engineered welded bin supports and wide aggregate belt with polyethylene bin guides and stainless steel lacer provides hours of trouble free production.
  • Calibrated Heavy duty rack and pinion gate controls allow for quick and easy settings resulting in precise metering of aggregates.

Water System

  • Front mounted Corrosion and UV resistant poly propylene water tanks provides water supply for concrete production
  • Tank is baffled to provide stability during transportation and eliminate shift in load
  • Hydraulic powered water pump, flow control valve, water meter and quick acting stainless steel globe valve gives operator precision control of water and appropriate water/cement ratio

Air System

  • Electronically controlled pneumatic, adjustable vibrators ensure and provide an accurate flow of material.
  • Adjustable electronic timer cube allows you to set the time of vibration proportionately to your aggregates

Cement System

  • Cement bin with weather tight hatch and bag breaking grate makes loading quick and easy, giving the capability to provide richer mix designs for customers, without running out of cement before aggregate.
  • Poly carbonate view window allows you to visually monitor level of remaining cement and exclusive CTI dual auger cement delivers exact amounts of cement required for mix design

Hydraulic System

  • High volume, low pressure hydraulic system with 208 litre tank (other sizes available) allows for continuous, safe operation without over heating
  • Hydraulic hoist with lock valve provides operator and employees a safe work area

Mix Auger

  • Advanced high energy mixing auger
  • Engineered pump master auger with box beam frame
  • Mix auger equipped with replaceable NI HARD wear blades and reverses for quick and easy clean out.
  • Iron man sealed bearing system for mixing auger

Volumetric Mixer recommended maintenance

Item Schedule Comments/Issues
Check the mixing chamber, chutes, auger, and bearings to ensure no concrete build up is evident After each pour Cement build up will reduce the efficiency & life of the Auger
Check Bins, Conveyors, Chains and Boards and ensure in good condition Monthly Poor condition effects the quality of concrete
Ensure that the cement viewing glass at the feed end of the cement screw auger is clear After each Pour Enables you to see cement falling into mixing chamber
Do not mix admixtures and ensure hoses and tanks are flushed with fresh water After each Job Mixing different admixtures can cause coagulation and blocking of pumps and lines
Check all rubber on auger and in mixing chamber. Repair and/or replace as required Monthly Damaged areas / items reduce mixer efficiency
Ensure Water Tank is clean with no evidence of contamination or sludge build up Weekly Dirty water will damage water pump and cause breakdowns.

Dirty water will reduce the quality of concreteMake sure the compressed Air is clean. Drain all filters on both the truck and mixer compressed air bottles.DailyWater in the air will drastically reduce equipment life and possibly cause breakdownsEnsure the cement bin is sealed and in good conditionAfter each Cement fillPoor condition seal can lead to contaminated cement causing blockages and breakdownsVisually inspect all wiring, hydraulic hoses and air lines for faults and report for repairsWeeklyDamaged wiring/hoses can cause breakdownsInspect all rubber fittings on mixer.
