Mammut Industrial Group Bunker Trailer

Mammut Industrial Group Bunker

Bunkers are used in various industries to transport bulk materials in powder form. Bunkers depending to their body, are used to carry cement, flour and other edible powders. The working in closed and sealed space of bunker is simple: loading by gravity and discharging by compressed air. The series of valves located in the powder passage are opened and closed according to a specific sequence so that the content in separate compartments can be drained off in order. Bunkers don’t have a separate chassis so it is quite necessary to think of some considerations in designing of the tank body so that it can be easily and safely joined to the axles and other sub-sections. Apparently during braking and other bunker maneuvers, all the longitudinal and lateral forces are transferred to the tank itself.

Pneumatic Discharge

To transfer contents of the bunkers, a small diesel compressor which is installed on the chassis provides required compressed air. The small diesel engine, which is usually air-cooled, operates a piston compressor. The compressor intakes air through the filters, squeezes it to a certain amount and consequently directs it into the hoses and piping system. This pressurized air first suspends the powder and then carries the suspended powder to required distance.
