60-80T capacity 1000 model batch type asphalt drum mix plant for road machinery
Product details
Max capacity:80t/h (Working under rated condition)
1. Cold feeding System
Cold feeders uses double-hopper-integration type, equipped with maintenance ladder, platform, and handrail. Variable frequency speed technology controls preliminary dosing.
Each cold aggregate ground hopper is equipped with conveying belt and empty alarm device, When the conveying quantity of cold feeder is lower than limit value or suddenly lack of aggregate, the signal will be sent to the control room immediately and appeared on computer interface in order to take quick reponse.
2. Drying drum
Dryer is made of heat-resisting and high-abrasive steel plates. Optimal layout of lifting blades providing exllent environment for aggregate conveying and heating, which greatly improves thermal efficiency. Dryer body is covered with rockwool layer outside with stainless steel plate; the foundation is made of heavy steel. Dryer body is driven by 4 groups of separate friction wheels and each group is equipped with separate speed reducer and motor.
3, Dust Collection System
Two level dust collection system (volute casing collector + bag house collector), with high and low temperature protection device for the system security.
Bag house collector using USA Dupont NEMEX bags, heat resisting and long life.
Environmental friendly, emission concentration is less than 20mg/Nm3, wtih dust collecting area 445 square meter and 55KW low noise induced draft fan.
The bag of the bag house filter adopts high temperature resistant material, which can withstand 220°C high temperature. Equipped with cold blast protection function against overheat.
4, Hot aggregate elevator
Hopper type hoister uses double rows of heavy chain to lift and shaft mounted reducer
to drive. The reducer is equipped with brake motor to prevent hoister from rotating reversely, solving the problem of jam from sudden power off or other causes. Chain spring tensioning devices are installed at both sides of hoister bottom; edge of elevating
hopper adopts wear-resisting design, wearable liners are fixed in both feeding & discharging channel; working platform is installed on top of hoister for easy maintenance.
5, Mixing tank
Double horizontal shaft mixing tank will reach to an optimum mixing effect, mixing arm, blade and lining are made of special anti-frication cast steel with life tiem more than 100,000 mixing batches, all linings are bolted outside of the tank, easy for maintenance and change. Mixing tank is driven by double-reducer, with oil-bath gearing working synchronously. Driven by two air cylinders, full open arc type discharging door can exhaust finished mixture rapidly which effectively reduces mixing cycle.
