Components (machinery and equipment) especially developed by STAG to be used in applications in the bulk material technology sector are provided to the market. Until today, many of these especially designed products have been exclusively used in our own systems. From now on, these unique products are made available to the global market and offered as independent products.
The impact mill has been specially designed for breaking up agglomerated material within the bulk product. This application is mainly used in the treatment of boiler ash originating from incineration plants.
STAG’s container handling system enables automated and dust-tight filling of roll-off containers. The
container is tilted with the traversing and tilting station, thus achieving an ideal filling level.
The double-sided sealing turn slide valve has been especially designed for pneumatic conveying as part of the STAG pressure conveying vessel technology. No other system can satisfy the high demands of this application.
STAG has gained an extensive experience with the volumetric dosing system. The system contains the dosing, the pneumatic conveying with product-specific air blast injector nozzle as well as the necessary air treatment.
The one-sided sealing turn slide valve has been especially designed for pneumatic conveying as part of the STAG pressure conveying vessel technology. No other system can satisfy the high demands of this application.
The Filling Adapter has a very wide field of application. STAG uses this system, among other things, for the emergency discharge of ash removal systems.
The closed STAG Conveyor Belt stands out through its dustproof design and its integrated scraper floor. With this construction method the conveyor belt can be operated by a slight vacuum.
The mechanical discharge aid „Silex“ is used for conveying poor flowing and not fluidizable bulk products. It is incorporated into round or angular-shaped silos, bunkers and containers.
For financial and ecological reasons, silo rail wagons are increasingly used for transporting bulk products. The regional distribution of these bulk products is ensured by appropriate silo trucks. The transhipment systems constitute the link for transhipment of materials from rail to road.
Chain conveyor are continuous conveyors and are suited for the conveyance of bulk products of all kind up to small-sized products and sludges.
The STAG diverter pot constitutes a patented development in the area of pneumatic convey-ance technology, replacing the pipe bend in a series of possible applications.
Injector:
Injectors are used for the simple, self-regulating in-feed of powdered and granular bulk products into pneumatic conveying lines without moving parts.
STAG has gained an extensive experience with the gravimetric dosing system. The system contains the dosing, the pneumatic conveying with product-specific air blast injector nozzle as well as the necessary air treatment.
The pressure conveying vessel is used by STAG when it comes to challenging tasks, high conveying rates and long con-veying distances. This pneumatic conveying application using the dense flow method combines energy-optimised conveying processes with perfect operational safety.
Designed for crushing lumps as well as agglomerated material within the bulk material.
In lump breaker applications, the oversize grain is prepared for subsequent pneumatic or mechanical conveying or ensiling procedures.
In addition to fluidization, STAG uses Fluid Floors for silos with multiple outlets.
The entire silo floor is equipped with a fluid cloth and enables the bulk material to be stored to flow off constantly and completely.
The Tubular Screw Conveyor is characterized by its versatility, especially at inclinations of 20 to 45
degrees. With a full-blade screw, it ensures efficient and continuous bulk material conveying in a wide
STAG offers foreign body traps and sieves for a wide range of applications. Special deflection heads are used in conveying lines, STAG develops customer-specific prototypes in down pipes and a standardized design is used for the impact mill.
STAG has been using dense-flow pipes made of steel for pneumatic conveying of bulk materials with many years of success. However, the service life of these dense-flow pipes is limited when pneumatically conveying extremely abrasive bulk materials.
The STAG discharge and dosing module is realized with two bulk material slides and an intermediate container. The dimensioning of the intermediate tank makes the application areas very versatile and easy to modify.
The Big-Bag Uptake Cross is a welded construction, which has been further refined by STAG during the last 50 years. The spring-loaded karabiners simplify the hanging in an out of the Big Bags. The bag clamp ensures that the dust exposure is reduced to a minimum.
The Multi screw dosing unit is a welded construction with integrated metering screw spiral. Via rotational speed and a unique calibration this construction ensures an exact volumetric dosing.
STAG offers a selected range of special gate valves in their product portfolio. All gate valves are designed and manufactured for customer-specific demands. At the request of customers the engineering special products are Europe-wide in use.
Discharge chain conveyors are installed at bunker outlet points or directly in boiler hoppers. The dimensioning and construction of the large inlet opening require detailed knowledge.
The four loops big bags are filled while hanging, the lifting movement being transferred to the load frame fitted with four vertically adjustable load hooks by means of a guide slide run by maintenance-free plastic rollers.
The bottom filling is used for conveying and storing bulk products without segregation.
The STAG excess / low pressure valve is used to protect containers and silos from either too high or too low pressure conditions.
Coarse particle separators are used in mechanical conveying processes of bulk products in order to eliminate larger particles (impurities). The benefits are an improved operational safety of the conveying system, which can be reduced in size after the coarse particle separator.
STAG uses bulk material-specific designs for fluidisation.
Tripple Nozzles are used as a discharge aid for bulk materials in containers, silos and downpipes.
The STAG Sampler is a high-precision solution for reliable sampling in industrial environments. Designed
to meet the requirements of various industries, this Sampler offers easy handling and precise
In conventional conveyances of powdered bulk materials through smooth pipes, the irregularity of the flow rises with the increasing pipe length. This in turn, increases the wear of the system.
The 3-way ball valve has been especially designed for use in bulk material rail wagons.
The truck turn slide valve and its weatherproof cover form a unit, which can be built into new or existing aluminium or steel bulk material containers (min. Ø 2400 mm).
Fluid channels are used in silos or bunkers where poor flowing products are stored. A fluid channel is installed slightly inclined, and the extensive aeration ensures an easy discharge of even poor flowing products.
