Gentle unloading of sodium perborate from bulk vehicles by pneumatic plug conveying
Subject: Unloading bulk vehicles; conveyor system; conveying distance 9 meters horizontal, 12 meters vertical
Client: Labud d.o.o., Zagreb, Croatia
Gericke Technology: Gentle unloading of bulk tankers; PTA-PL system (Pulseline®). Mobile docking station with integral controlunit, additional equipment for controlled and pulsed secondary air, injections along the pipe (patented)
Application: Unloading bulk tanker and low-friction conveying of sodium perborate tetrahydrate to the bulk silo
Material conveyed: Sodium perborate tetrahydrate (washing powder ingredient); bulk density: 0.8 kg/l
Particle size physical properties: ds50 approx. 300 μm; free-flowing, fragile
Output: 8 t/h or 10 m3/h
Product source: Bulk vehicle (30 m3)
Product destination: Storage silo
System requirements: Dust-free and low-friction conveying. Reliable operation in summer and winter; use of dried and purified compressed air from the existing factory compressed air system. Minimum conveying air volume
Fine granulated washing powder is delivered in a bulk vehicle and transported pneumatically to a storage silo. The new equipment includes the gentle action with a PTA-PL mobile bulk unloading system (Pulseline®) which replaces the original bulk unloading high velocity system reducing the proportion of fine particles by approximatly 15%!
The product is transported another 60 m from the storage silo to the day bin. It is also transported slowly over this section by pneumatic conveying using a pressure tank and controlled pulsated bypass air.
