Asphalt Plant 120 -140 t/h

• Capacity 120-140 ton/hour on the basis of 3% material’s moisture.
• Control system: full automatic, half automatic and manual.
• Material’s temperature from 150-180 centigrade degree.
• Plant capacity could change up to 15% with respect to grain size, special weight, special temperature and material’s moisture (sand and ballast), type of asphalt and also environmental conditions (pressure and temperature) and fuel’s type.

Four individual feeder bins each with a 15 tonne capacity.
Each bin top and mid-section is reinforced for added rigidity.
Bin bottom is designed with a tapered opening to minimise bridging.
Each bin is fitted with independent invertors linked to the control room, allowing accurate adjustment of the aggregate proportions on the go.

Aggregates from the bucket elevator is discharged over an anti-abrasion lining and then sprayed over the entire screening area. Totally enclosed dust sealed housing, discharge chute, with inspection doors, giving access for inspection, maintenance and mesh changing.

• Screening Method :Fully enclosed counter weight vibration
• Screen Material :High resistance stainless steel alloy
• Output :4 product sizes plus over size.

Hot Elevator Unit:
The hot aggregate bucket elevator is a totally enclosed chain driven system.

Bucket tips are double reinforced for maximum durability.The elevator unit is electrically driven from the head shaft via a chain system.

Electromotor Gearbox: 120 TPH 11 K.w80 RPM

Filler Elevator Unit :

The bucket filler elevator is standard to all plants.The warm reclaimed filler obtained from the drying process via the cyclone is collected and fed to the mixing tower.Warm filler is covered better and more quickly by the bitumen and as an incidental benefit; the specific energy consumption is reduced.As an option, a second mineral filler elevator can be supplied and located parallel to the reclaimed filler elevator.

Electromotor Gearbox      5.5 K.w 30 RPM

The aggregates are fed by the dryer feed belt into the lower part of the dryer drum in which the initial section contains a series of spiral flights which feed the material towards the internal flights. The flights have been designed in such a way as to lift the aggregates and then drop them in a thin veil in front of the burner flame ensuring an efficient drying process.The Drying unit is started through Siemens soft start technology, resulting in a smooth activation process. The burner and the drum tube form a precisely balanced unit, the combined effect of which is low fuel consumption, exit height and gas temperature and secondary air intake resulting in the improvement and economy of the mixing unit as a whole.

• Drum Type: Single continuous spiral steel shell is used; in order to maximize heating ,Efficiency, prolong drum shell life and minimize fuel consumption.
• Friction ring:Width 17 cm, Thickness 7 cm with 4 heavy duty rollers.
• Activation: Through Siemens Soft Start. Resulting in a low rpm start up gradually working up to full load rpm.
• Contactors: Tele-mechanic.

• Main tank diameter 2400 mm and 6 m height made from 5 mm steel sheets.
• Chimney with 1300 mm diameter and 6 m height made from 5 mm steel sheets
• Stands : 3 m height made from 8 inch pipes.
• One water pump with 11 KW electro-motor and 3000 rpm.
• Equipped with 75 nozzle water sprinkler.
• Fender cap.
• Joint pipes and valves used in water recycle pool.
• Connector channels between the filter and exhaust fan.

The mixing unit contains Twin shaft high capacity paddles with high wear resistance liners. The mixing blades feature optimized shapes and materials to ensure a long service lifespan and easy maintenance. Using load cell technology the fully automatic weighing unit is designed to individually weigh the aggregate, filler and bitumen to provide consistent recipes. The filler dispatch bin is designed to cover the entire span of the mixing unit in order to provide uniform filler distribution. Pneumatic system controls the opening and closing of the storage bin outlet. Constant air pressure is achieved through the over sized compressor and receiver.

• Outlets :Pneumatic load cell technology
• Cycle weighing time :15 Sec
• Cycle mixing time :30 Sec

Two thermometer system. one controls the burner: the other  is the back up that completely turns off the burner if the first thermostat is not functioning. pressure switch controls the pressure of the pump. If the pump is not working and pressure drops the pressure switch turns off the burner.
