NEO MAKİNA ve MÜHENDİSLİK A.Ş. builds turnkey asphalt plants and concrete batching plants for road contractors, municipalities and infrastructure projects. Batch-type asphalt plants consist of cold feed, drying drum, hot elevator and screening tower, separate aggregate-filler-bitumen scales, twin-shaft mixer and hot-mix storage silo; they produce hot-mix asphalt to EN 13108 at 60–320 t/h in stationary or mobile configuration. Combined facilities with a concrete batching plant on the same site are offered; our references include a 200 t/day PmB (polymer-modified bitumen) preparation plant in Bulgaria.
Asphalt Plant Process Flow
- Cold feed: 4–6 compartment cold aggregate bins, variable-speed dosing belts and collecting belt; scalping screen for oversize.
- Drying and heating: Counter-flow rotary drying drum; special flight design veils the aggregate for maximum heat transfer; modulating burner (fuel oil, natural gas, LPG or pulverised coal); aggregate heated to 150–180 °C.
- Dust collection: Pre-separator and bag filter (<20 mg/Nm³ emission); captured filler (stone dust) returned to the process via hot elevator; filler silo.
- Hot screening and storage: Hot bucket elevator; 4–6 deck vibrating screen into 0–5, 5–12, 12–25 mm fractions; insulated hot bins, bypass line.
- Weighing: Separate load-cell scales for aggregate, filler and bitumen (±0.5%); heated bitumen scale; additive (cellulose fibre, polymer) dosing.
- Mixing: Twin-shaft mixer with Ni-Hard liners and arms; homogeneous coating in 40–50 seconds; 1–5 t batches.
- Dispatch: Direct truck loading under the mixer or heated hot-mix storage silo (50–300 t); weighbridge and dispatch software.
Auxiliary Systems
- Bitumen storage: 50–100 m³ horizontal/vertical insulated bitumen tanks; heating (150–170 °C) by thermal oil heater, traced pipelines, bitumen pumps; PmB and emulsion tanks.
- Polymer-modified bitumen (PmB) units: High-shear mill, maturation tanks and automation; SBS modification; units up to 200 t/day.
- Reclaimed asphalt (RAP): Cold RAP bin, elevator and ring feed for 10–30% RAP; up to 50% with parallel drum.
- Warm-mix asphalt (WMA): Foamed bitumen or additive dosing systems to lower production temperature by 20–40 °C.
- Automation: PLC + PC recipe management, automatic scale calibration, temperature and moisture correction, batch reports, weighbridge-dispatch-ERP integration.
Plant Configurations
- Stationary plants: 120 – 320 t/h; long-term high-volume production; steel tower, concrete foundations; enclosure and noise-insulation options.
- Mobile plants: 60 – 160 t/h; tower, dryer and filter on wheeled chassis; erected and relocated in 2–4 weeks; construction sites and short-term projects.
- Compact plants: 80 – 160 t/h; low height, fast erection; urban sites.
- Continuous (drum-mix) plants: On request; high capacity and low investment for single-mix production.
Concrete Batching Plant Integration
On road and infrastructure sites, the asphalt plant and concrete batching plant are installed together with shared aggregate stock, weighbridge, loading and control building; for 30–240 m³/h plant options see Concrete Batching Plants. A three-way integrated site solution with a crushing and screening plant for aggregate production is available.
Typical Application Range
- Asphalt capacity: 60 – 320 t/h; batch size 1 – 5 t
- Products: hot-mix asphalt (wearing, binder, base courses), stone mastic asphalt (SMA), PmB mixes, warm-mix asphalt, RAP-containing mixes
- Fuel: fuel oil, natural gas, LPG, pulverised coal (pulverised system)
- Standards: EN 13108 (bituminous mixtures), EN 12697 (test methods), CE Machinery Directive, EN 536 (asphalt plant safety), national industrial air-pollution regulation
Why NEO MAKİNA?
- Quality: Separate scales, automatic calibration and temperature control for recipe compliance in every batch; low standard deviation.
- Energy efficiency: Counter-flow drum, insulation and burner modulation for low fuel consumption (typically 6–8 kg fuel oil per tonne of asphalt at 4% moisture); thermal oil and boiler systems are our own manufacture.
- Environment: Bag filter, filler recovery, closed bitumen handling and odour control; carbon reduction with RAP and WMA.
- Single-source delivery: Feasibility, layout, steel structure, manufacturing, erection, automation, commissioning, operator training and in-season support; overseas erection experience.
Frequently Asked Questions
Batch or continuous (drum-mix) plant?
Batch plants are standard for varied recipes, SMA and PmB mixes with tight quality control; drum-mix is considered for high tonnage of a single mix at low investment.
Can RAP be used?
Yes. 10–30% reclaimed asphalt via ring feed on standard plants and up to 50% with parallel-drum systems, lowering bitumen and aggregate cost.
How long does installation take?
For a 160 t/h stationary plant, manufacturing takes 10–14 weeks, erection and commissioning after foundations 4–6 weeks; mobile plants are erected on site in 2–4 weeks.
