Sinfimasa specializes in custom-designed and manufactured shaftless screw conveyors, a solution aimed at efficiently transporting sticky products, sludges, and a variety of food and chemical products. These systems are optimized for materials that are lumpy or of irregular nature. Understanding that each production process is unique, Sinfimasa provides tailored solutions based on the specific needs of each industrial plant, working conditions, and products to be transported. Their team of specialized engineers is prepared to develop a screw conveyor that perfectly fits the application, ensuring maximum efficiency and reliability. Sinfimasa incorporates components from leading market brands like SEW motors and SKF bearings, promising not only exceptional performance but also outstanding longevity with low maintenance costs. Key features of their shaftless screw conveyors include an internal shaft-free design, suitable for transporting various shapes and sizes of materials, especially sticky or irregular ones. The friction bed, made from high-resistance polyethylene or anti-wear steel, ensures smooth movement and reduced wear. These conveyors are versatile, ideal for industries dealing with urban and industrial solid waste, water treatment, and composting. Advantages of Sinfimasa's screw conveyors are enhanced efficiency in transporting challenging materials, robustness and reliability due to high-quality components and ingenious design, customized solutions for perfect integration into production lines, and low maintenance requirements for continuous operation with minimal intervention.

The shaftless spiral conveyor from SPIRAC ensures higher fill rate and lower speeds resulting in less wear and therefore less maintenance and downtime. Although the spirals can be made from many different types of material, the primary material is a special steel from Sweden that has mechanical properties that give the SPIRAC coil a very high tensile strength. SPIRAC shaftless spiral conveyors are designed for transporting materials that are otherwise difficult to handle, such as dewatered sludge, screenings, grit, industrial sludge and other sticky, viscous, fibrous materials.

The JOEST Shakeout is a high-performance solution for the automated separation of sand lumps and castings in foundry production. Especially in wet casting processes, it ensures reliable and gentle material processing – even under high temperatures and mechanical loads. Its modular design, robust construction, and precisely adjustable vibration parameters allow optimal adaptation to a wide variety of requirements. The use of high-quality materials such as manganese steel, individually configurable grate systems, and a low-vibration design ensures maximum operational safety while keeping noise levels low. Combined with automated control systems, energy-efficient drives, and ergonomic maintenance concepts, the shakeout becomes a key component of modern foundry operations.

The pocket filter INFA-MAT AM is a sturdy and easily mechanical cleanable filter unit. Because of the compact design the installation is also possible in case of constricted space. The proven shaking system ensures an effective cleaning of the filter cloth at low investment and maintenance costs. The modular variety of the INFA-MAT pocket filter series allows an optimum adaption of the filter units to specific needs. Several types are possible for different dedusting tasks: Vent filters with/without fan for dedusting of conveyor equipment or silos Dedusting unit with hopper and dust bin. Also available with integrated fan. Design possible as one chamber filter or multi chamber filter Bag emptying filter consisting of sack discharge, filter unit and integrated suction fan Optional secondary filter stage for residual dust contents less than 1 mg/m³ Filter surface from 6 - 180 m² for volume flows up to approx. 16,000 m³/h Operating mode: INFA-MAT pocket filters are mechanically cleaned by a shaking system after completing the dedusting process. Fans of the filter units have to be switched off during cleaning. Cleaning period is normally 30 seconds. The filter cloth with its combined pockets is easily accessible via a big front door. It is kept in a sliding frame, so that change of filter media is quickly and easily practicable.

Our BC-M coating can be used successfully for applications as a conveyor belt scraper on heavily adherent materials. The cost advantage over HM segments is that we use a continuous hard material rail over the entire length of the scraper during preparation.

Our shear beam load cells are specifically designed to measure forces through shear stress. These sensors are widely used in weighing systems and force measurement applications where precision is essential, such as production lines, weighbridges, silo's, hoppers and heavy industrial machinery. Thanks to our advanced strain gauge technology, our load cells deliver reliable and highly accurate measurements, even in the most demanding environments.

The loaders type JBM 500 are specific loaders for loading of dry, free flowing bulk solid on ships. Like all loading systems developed by Stanelle the JBM 500 Ship Loader is characterized by reliability, precision and high durability.

The innovative, electro-hydraulic fragmentation technology of ImpulsTec GmbH offers great application potential for the recycling of composites and complex industrial materials and can thus make a contribution to the development of previously unexploited secondary sources of raw materials and long-term resource conservation. With its high material selectivity, ImpulsTec GmbH's shock wave technology for industrial applications provides enhanced fragmentation at the interfaces of different materials. It is thus predestinated for applications like the separation of complex industrial materials and composites.

The SHOCK-BLOWER® reliably clears material deposits and keeps bulk solids flowing. AGRICHEMA’s SHOCK-BLOWER® system enables individual solutions for all sectors of the bulk solids industry. For over 40 years now, buildups of bulk solids have been successfully cleared with the SHOCK-BLOWER® air blast system. SHOCK-BLOWER® air blast devices store compressed air (or inert gas), then release it as needed in the manner of an explosion. SHOCK-BLOWER® air blast devices with hot-dip galvanized compressed air tanks and valve seats made from CrNi steel have been designed for a long service life and high levels of operational safety. Thanks to the unique valve technology, which pneumatically closes the piston in just milliseconds, you can save up to 50% compressed air/power. At normal temperature range SHOCK-BLOWER®s are used in transfer hoppers and chutes, dust pipes, filters, mills, sifting machines and more. At high temperature range SHOCK-BLOWER®s are used in cyclones and pipes, preheaters and heat exchangers, clinker brick chutes, grate cooler inlets, incineration plants, small-scale firing systems and lots of other places. The POWER PACK system for the SHOCK-BLOWER® is intended for use when space for installing and servicing multiple SHOCK-BLOWER® units is very tight. The POWER PACK station with 1 compressed air tank and up to 8 external valve units can be installed in easily accessible places. The exhaust points are connected via appropriate pipes, enabling air to be blasted from several meters’ distance. The strength of the air blasts is not appreciably reduced by the extra distance.

The SMS short path evaporators guarantee excellent results when evaporating, concentrating, distilling or devolatilising temperature-sensitive, high-boiling mixtures. The internal condenser minimises the pressure loss due to its short distance from the evaporation surface. Therefore, short path evaporators can operate under fine vacuum and with correspondingly low boiling temperatures. Even extremely heat-sensitive products, such as vitamins and flavourings, can be distilled without causing any thermal damage.
