Company Presentation:
Bulk material technology
Pneumatic and mechanical conveying technology
Storage technology
Complete systems ( ash handling, cement handling, animal meal handling, sewage - sludge handling, etc.) and components ( pressure conveying vessels with controller, jet conveyor, chain conveyor, lump breaker, impactor mill etc.) in part of pneumatic and mechanical bulk material handling systems and silo storage technology.
Own Test Center with test plant, laboratory, training facility for investigations with different bulk materials and large scale plant dimensioning and layout, checking out components and new developments, demonstrations, training courses and seminars.
Rail-Waggon Service-Center
STAG - our core skills are in the storing, conveying and metering of bulk materials.
Technical research centre
Bulk materials analyses in our own laboratory
We analyse the grain-size distribution, conduct Jenike shear tests, identify air retention capabilities, measure settling velocities and determine long-term compacting rates. Using an up-scaling model we extrapolate such data to each and every system size.
Functionality tests before delivery
We can demonstrate all the functionalities under real-life conditions in our technical research centre.
Comprehensive Service
Our services include systems maintenance and optimisation and also in-depth analyses of bulk materials, process engineering tests in our own technical research centre, the installation and commissioning of systems, inspections, revisions, spare part supply (most of them in stock) as well as technical training sessions and seminars for our customers.
Services for silo wagons and bulk transporters
We are able to offer our customers optimum service through our own service stations.
Spare parts supply services
Thanks to our spare parts warehousing, a large selection of third-party products used in our systems is available at any time.
Engineering, projectmanagement and systems engineering and construction from an initial idea to a turnkey installation
Our consultation activities include:
Invitations to tender, submissions, evaluation of bids and contract management
Exercising powers of attorney for clients
ATEX explosion protection concepts
Cost-benefit analyses, investment appraisals
Systems engineering and construction, general mechanical engineering solutions
Project management, construction-site management, construction supervision
Quality, cost and progress control
Risk analyses
etc.
Applications
Focusing on a few selected industries, the application examples show the diversity of environments in which our products are used.
Cement, lime and gypsum industries
including also the areas of alternative energies and manufacturing process applications.
Practical applications
Wagon unloading systems
Metering systems
Mechanical and pneumatic conveyor systems
Transhipment and silo systems
Applications for the following products:
Ash from combustion systems
Bypass kiln dust
Lignite
Iron (II) sulphate, tin sulphate
Foundry sand and granulated cinders
Gypsum
Limestone dust, lump lime, lime, hydrated lime and other lime products
Microsilica
Raw meal
Sawdust
Cement products
Construction materials industry
Handling of construction materials, and, another specialist application, the bottom filling of storage silos for the production of mixed plaster - free of any segregation. Our special dense phase conveying technology, combined with counterflow bottom filling.
Applications for the following products:
Screed and flowing screeds
Dry mortar and mixed plasters
Adhesives
Energy and power generation industry
Removal of ash from boiler and filter systems. They range from elaborate transportation and treatment systems to silos for intermediate storage and loading facilities for bulk transporters (containers or big bags).
The handling of flue gas cleaning additives is another field of application. These systems include all elements of bulk materials handling from delivery, storage, distribution, and metering to their injection into the flue gas treatment process.
Applications for the following products:
Ash from waste-to-energy power plants (boilers and flue gas treatment)
Ash from coal-fired power stations ( electrostatic filters )
Ash from sewage sludge incinerator installations (boilers and flue gas treatment)
Ash from the combustion of bark, paper sludge and wood ( boilers and flue gas treatment )
Activated charcoal
Lignite coke
Bicarbonate
Hydrated lime
Mixtures of hydrated lime and coal
Soda ashes
Biomass and other alternative fuels
These solutions usually include hopper systems with innovative discharge technologies that allow for optimum storage and metered feeding of the fuels into the actual power plant systems.
Practical applications
Hopper filling systems
Hopper discharge systems
Metering systems
Sizing systems
Mechanical conveyor systems
Applications for the following products:
Barks and shredded wood waste
Various sewage sludges
Plastics
Chemical industry
New developments frequently feature among them, but there are also volume products such as terephtalic acid, salt and soda.
Practical applications:
Big bag filling and discharge systems
Metering systems
Mechanical conveyor systems
Pneumatic conveyor systems
Transhipment systems (from silo rail wagons and bulk road transporters to silo systems)
Silo discharge systems
Applications for the following products:
Salt
Soda
Terephtalic acid
Washing powder
etc.
Diverse fields of application in other industries
Apart from the applications above so far we have also managed and completed projects in industries that we have not listed separately.
Practical applications
To give you an even greater insight into the diversity of our activities we have listed some further projects which we have successfully implemented. These examples complement this review of our far-reaching fields of operation:
Salt stores and municipal salt transhipment systems
Vacuum/pressure pneumatic conveying systems to clean silo wagons
Slag processing and transport systems for waste-to-energy power plants
Sludge handling in water treatment plants
Hydraulic transport and metering of glass beads
All types of train-to-truck transhipment systems
STAG technologies:
