FAM-1440 Double Mixer

What is a Double Mixer in FAM-1440?

A double mixer is a dual-chamber mixing system used to prepare two types of material batches simultaneously—typically:

Base concrete mix (fly ash, cement, stone dust, etc.)
Color mix or topping (used for paver blocks or interlocking bricks)

In the FAM-1440 fly ash brick making plant, the double mixer boosts efficiency by preparing two distinct batches at once, thereby reducing downtime and increasing throughput.

How It’s Made – Components & Manufacturing

???? Key Components:

Part	Material	Purpose
Mixer Pan x 2	Mild Steel / MS + Hard Plate	Dual mixing chambers
Gearbox	Heavy-duty Cast Iron	Power transmission for mixing arms
Mixing Blades (Arms)	Hardened Alloy Steel	Blend materials evenly
Main Frame	ISMC/ISMB Section	Structural base
Drive Motor	7.5–10 HP (x2)	Powers individual mixers
Discharge Door	Manually or pneumatically operated	Controlled output
Bearings & Shaft	EN8 / EN19	High torque and load-bearing capacity

Manufacturing Process:

Design Engineering – CAD design for two mixer pans with optimized blade rotation.
Fabrication – Laser-cut mild steel plates are bent and welded to form pans.
Machining – Shafts and gearbox components are precision-machined.
Assembly – Each pan gets its own gearbox, arms, and motor mounted.
Electricals – Motors wired individually or to a PLC for smart control.
Testing – Dry and wet testing done to ensure smooth, uniform mixing.

How It Works

Raw Material Input
Different materials are loaded into the two pans—e.g., fly ash mix in one, color mix in the other.
Independent Operation
Each mixer works on its own motor and gearbox to mix the content uniformly.
Simultaneous Discharge
After mixing (usually 2–4 mins), materials are discharged into trolleys or feeders for molding.
Cycle Reset
Mixers are cleaned and reset for the next batch, running in a continuous loop.

Paver block manufacturing setups
Industrial tile and color topping production units
Government construction material plants
High-output manufacturing units with automated lines

FAQs – Frequently Asked Questions

Q1: Is it better than a single mixer?

A: Absolutely. A double mixer cuts down wait time by preparing two different batches at once—ideal for automated lines.

Q2: Can I mix different materials in both pans?

A: Yes. One mixer can handle fly ash while the other can be used for color mix or cement slurry.

Q3: What maintenance is needed?

Daily: Clean pans and remove stuck mix
Weekly: Check gear oil and blade condition
Monthly: Lubricate bearings and inspect motor alignment

Q4: Is it compatible with PLC automation?

A: Yes. It can be integrated with relay or PLC panels for fully automatic operations.

Q5: What’s the expected life span?

A: With regular maintenance, a double mixer lasts 8–10 years in industrial use.

Conclusion

The FAM-1440 Double Mixer is a game-changing component for modern fly ash brick and block manufacturing units. Its dual mixing capability enhances productivity, versatility, and cost-efficiency by ensuring two types of mix are always ready without delay.

If you're running a semi or fully automatic line like the FAM-1440, upgrading to a double mixer is essential for scaling operations and optimizing production cycles.
