The solids solutions group offers nine well-engineered and tested pneumatic conveying systems using components assembled by the company for the pneumatic conveying (pneumatic pressure- and vacuum-conveying).
With 45 engineers and technicians as well as highly trained staff in assembly, installation and service we are objectively able to offer the most advantageous system for pneumatic conveying for every product and every task.
Dilute phase conveying classic dilute phase conveying system for suction- or pressureconveying.
Particles and particle clouds orstrands are carried by
air flow.
The discharging of bulk solids from silos or containers requires improving the product's flow characteristics.
Many bulk solids do not discharge freely through the generally feasible, expedient filling/discharge cross sections.
Flow is achieved by the application of force to loosen up settled grains/particles/fibres.
Depending on product characteristics, operating conditions and the type of task, vibration, fluidisation / ventilation, or mechanical agitation / mechanical tumbling is selected as a suitable method for discharging.
The solids discharging devices are offered in the 4 Designlines solids Basic, solids Clean, solids Hygienic, solids Heavy.
In the field “Mechanical Conveying” are used rotary valves as well as screws.
S.S.T.-Schüttguttechnik GmbH offers rotary valves in the following designs: Standard, Protection system, Clean and Hygienic.
There are two designs of screw conveyors: tubular and trough. The screw's helix can be either full-bladed or shaftless. Screw conveyors are used both in heavy industry and in the fine chemicals industry. Screw conveyors basically consist of a trough or tube, the screw, which consists of a screw shaft with a helical blade, and a drive unit. Carbon or stainless steels as well as wear-resistant or heat-resistant materials are used for this purpose.
Our experts will select the proper rotary valve or screw type for your application depending on product characteristics, operating conditions and the type of task.
Easy top accessibility with demountable cover, well possibility of cleaning and simple inspection or revision.
Bulk solids are filled into or conveyed to specialised vehicles, big bags / freight containers, barrels or other units.
Filling is often combined with weighing and metering. Precision - i.e., the correct detection of the filled weight - reproducibility and metering control are crucial here. Usability is also a key issue.
The filling process can be fully automated through a complete electrical and pneumatic installation with integrated control.
Bulk solids are discharged from: Big bags, containers, sacks, or barrels. The reliable and usable complete solution provides Big bag attachment, dustproof connection, discharging and integrated control.
The container to be discharged is moved into a suitable position. Then the solid goods are discharged, either by free-fall or using a discharging device or metering device. Frequently, a discharging tool is required to facilitate product flow and to ensure a complete discharge.
1. Filling the metering unit, resp. drawing product from store
2. Discharging the metering device, e.g. chambers, pockets, or cells, and supplying a fixed product quantity to the downstream process.
The objectives are a high volumetric metering accuracy, as well as continuity and reproducibility. Ideally, this objective is achieved by 100% filling and then 100% discharging isolated metering units.
Typical volumetric metering devices:
Weighing includes all methods of mass determination used in a system, including the use of mechanics, electronics, controls and peripherals.
A scale's method of operation is determined by the process conditions: Either continuous operation or batch operation is required.
A scale consists of the following components: A tray for holding goods for weighing until their discharge, a load frame/weighing module, peripherals including supply and discharge metering devices, a measuring amplifier with mass indicator, and a metering control unit.
S.S.T. Schüttguttechnik GmbH introduces on the German market a new brand of gravimetric micro feeders and powdering machines on the brand name Fine dosing. Thanks to an exclusive principle of extraction, highly developed, Fine dosing system is creating new standards in term of accuracy, speed and flexibility.
How does this technology work?
Take a coin on a paper sheet, and move it with an alternate movement whom return speed is higher than forward way. You can see that the coin is moving to the right side of the sheet…
Movement is given by a mechanical mechanism working in oil bath, designed for long term operation with low maintenance needs.
Based on this principle; a full range of advanced feeders and solutions has been developed: loss-in-weight feeders, Micro feeders of high accuracy, powdering machines, multi heads volumetric feeders
Rotary valves are used for the dosing, feeding or the discharge of fine-grained and powdered materials or granulates.
S.S.T.-Schüttguttechnik GmbH offers rotary valves in the following designs: Basic, Protection system, Clean and Hygienic.
Our experts will select the proper rotary valve or screw type for your application depending on product characteristics, operating conditions and the type of task.
Despite the broad range of available shut-off devices for solids it can be quite a challenge to find a suitable device for a particular set of requirements.
Requirements might be, for instance:
Pressure-resistant, dustproof and reliable:
As of May 2002, shut-off devices for bulk solids with operating pressures exceeding 0.5 bars are required to fulfil the new Pressure Equipment Directive 97/23/EC.
Typical shut-off devices for bulk solids:
