In the context of increasingly stringent environmental standards, the dust filter system is no longer a secondary item, but a vital factor for a modern asphalt concrete mixing station. With the TTM mixing station, the dust filter system is designed systematically, synchronously, and optimally from the ground up.

1. Filter Bag Arrangement on the Dryer Drum – Compact Footprint, Heat Retention, Quick Installation

Unlike many traditional designs, TTM’s dust filter system is arranged directly on the dryer drum (spiral drum).

This design brings three extremely important benefits:

Space-saving: suitable for construction sites with limited space

Shortened installation time: reduced auxiliary structure volume

Reduced heat loss: shorter hot air duct, lower loss

In short: compact – fast – energy-saving.

2. 50mm Insulated Ducts – Keeping Heat is Keeping Money

The entire duct system of the TTM station is wrapped in a thick 50mm insulation layer. It may sound simple, but this is a truly valuable detail.

Actual measurements at several stations show:

Significant reduction in heat loss

Fuel savings of 2–3%

Real example:

Station operates 200,000 tons/year

Average fuel consumption: ~5 liters of oil/ton

Total consumption: ~1,000,000 kg of oil/year

Fuel cost ~ 19 billion VND/year

Just saving 2–3% can reduce costs by about 600 million VND each year. This is not theory – this is real money.

3. Nomex Filter Bags (USA) – Heat Resistant up to 250°C, Durable and Stable

TTM uses Nomex filter bags from the USA – a leading brand in industrial dust filter materials.

Outstanding advantages:

Heat resistance up to 250°C

Stable operation in continuously hot gas environments

High durability, minimal performance degradation over time

This is a mandatory choice if you want the station to operate long-term without having to “change bags like changing clothes”.

4. High Capacity 110 kW Exhaust Fan – Clean Air, Dust Levels Below 20 mg/Nm³

With the TTM 160 tons/hour mixing station, the dust filter system is equipped with a high-capacity 110 kW exhaust fan.

The role of the exhaust fan:

Ensure stable air flow

Increase dust filtration efficiency

Prevent dust from reversing into the system

Output results:

Dust concentration < 20 mg/Nm³

Strictly meets current environmental standards

Reduces impact on surrounding residential areas

This is a clear differentiator for TTM compared to many mixing stations on the market.

5. Large Number of Filter Bags – Filtration Area up to ~650 m²

With the TTM model (for example, the 160 tons/hour line), the system can use up to 608 filter bags, significantly more than conventional designs.

Total filtration area ~650 m² – Even dust load distribution – High and stable filtration efficiency

A large filtration area means:

Less overload

Longer bag lifespan

Consistently stable emission quality

6. Easy Replacement – Filter Bag Lifespan up to 5 Years

One feature that is very appreciated by operators is the easy-to-replace filter bag design. No complexity, no time wasted on complicated disassembly.

Average lifespan: up to 5 years

Depends on operational capacity and station run time

Reduces maintenance costs, reduces station downtime

One-time investment – long-lasting – no headaches.

7. Good Dust Filtration is Not Just Environmental – But Also Economic Efficiency

Many people think that dust filtration is only to “deal with the environment”. This is wrong. Good dust filtration is to:

Retain heat → save fuel

Station runs stably → less downtime

More durable equipment → reduce long-term costs

With TTM, the filter bag system is not just the “lungs”, but also the financial filter for the entire station.
