7 STEPS TO HOW HOLCOMBE MIXERS REALLY WORK
You’ve heard how volumetric concrete mixers offer increased flexibility, environmental protection, quality control, and serious cost savings. But how do mobile mixers really work? Stick with us and scroll to see why volumetric concrete mixers assure quality concrete every time.
step 1
Aggregate Stored & Mixed On-Site
Holcombe Mixers volumetric concrete mixer trucks hold rock, sand, cement, water, and additives in separate bins and are mixed on site with a 9’ x 12” mixing auger.
step 2
Combined With Precision
Rock and sand are conveyed through calibrated strike off gates while cement is metered through a high precision screw conveyor at a constant rate synchronously to rock and sand.
step 3
Tailored To Mix Specification
Water is pumped from water tank while admixtures are pumped from three separated tanks. All are electronically measured and dispensed to mix specification.
step 4
Equipped with Color & Fiber Feeders
Color pigment, fiber and other additives are metered in with rock, sand, cement, water and chemicals.
step 5
Calibrated by Weight
All materials are calibrated by weight to lock in machine settings to produce all mix designs.
step 6
PLC Display Supported
Mix designs are entered into our simple one-button operation system to store mix designs, get real-time pour data, and print batch tickets when needed. Mix design calculation includes:
- Gate settings
- Counts per cy/m3
- Water flow rate
- Admix and Color flow rate
- Feed rate and water/cement (W/C) ratio
step 7
No Margin For Error
All mix designs are yield tested with ¼ cy/m3 test box to ensure correct volume being dispensed.
