BIGBAG discharging stations

As far as possible, BIGBAGs will be discharged without any dust and the product will be fed to the sequential process The feeding of the BIGBAGs will be realized by means of fork lift truck or by means of chain hoist. Automatic re-tightening units and discharging auxiliary devices support, according to the flow properties of the product, the discharging process.

• Strong load frame with boom for lifting gear
• Chain pull with electric power supply
• Lower frame with safety table or alternatively also available with the discharge aid "Wippe";
• Resealing device, manual

The »Wippe« discharge aid is fitted with metal plates which, during discharge, continuously adapt their position to the BIGBAG shape.

Combined filling stations

Schreier filling stations for different types of packages (e. g. BIGBAG, container or barrel) and for different package sizes in design being appropriate for calibration. Because of the central lifting column, the access is possible from three sides.

The fully automatic control enables the integration into a process control system. According to the type of package to be filled, the filling head, for being sealed, will be equipped with a blowing collar or with a filler cover and with initiators.

BIGBAG filling: The holding arms are moving upwards into horizontal position. A pallet will be put onto the balance and the BIGBAG loops will be hanged into the holding arms. The inlet socket, slipped over the filling pipe, will be sealed by means of blowing collar. The filling process begins after having tightened the BIGBAG and after having blown up the same with air.

Container filling: The container will be positioned on the balance by means of centering angular steels and by means of interrogation through initiators. The filling head moves into the container, the blowing collar seals and the filling process starts.

Barrel filling: According to the diameter of barrel, an adapter piece will be inserted for compensating the different infeed openings. The roller conveyor supports the supply of barrel. After the positioning by means of centering angular steels, the filling head moves into the barrel, the blowing collar seals and the filling process starts.

Container discharging stations

The container discharging stations are consisting essentially of a spring-supported docking system with supporting frame, of a base frame and, if required, of a vibrating device as well as of a weighing system.

• Range of application: Potentially explosive zone 1
• Integrated in a floor construction
• Executed as continuous differential proportioning weighing machine with interface to a local process control system
• Spring-supported docking system
• Vibrating frame with pneumatic swivelling clamper for holding the containers
• Shut-off valve
• Discharging screw for the fine / coarse dosing
• For the purpose of cleaning, the screw tube and the screw can be mounted and dismounted easily and quickly 
• Product-exposed components Hasteloy HC 4, otherwise material 1.4571

Lump disintegrator

For disintegrating soft to medium hard agglomerates in bulk materials. The supplied bulk material will be disintegrated on the grate by means of rotating disintegrating tools and in the further course of the disintegration it will be discharged downwards. The disintegrating tools, being staggered, guarantee a continuous mode of operation with greatest possible flow rate capacity.

In case of the here shown lump disintegrator it concerns a round design for being installed into a piping.

Screw-type metering machine

Precise charging, discharging, filling, weighing and dosing – the bulk material and the type of problem determine the design, the mode of operation, the capacity and further performance characteristics of the screw conveyors and of the conveying screws.

Continuous and discontinuous volumetric as well as gravimetric procedures will be realized. Tailor-made solutions with regard to the user's claims concerning the dosing processes.

Small-component weighing station with vessel balance. Charging with four screw conveyors. 

• Conveying capacity up to 40 l/h
• Material of stainless steel, electropolished
• For purposes of cleaning dismountable in a matter of seconds
