Frequently asked questions about custom components
What are custom components in bulk material handling?
Custom components are purpose-built parts and assemblies for conveying, unloading, separating or metering bulk materials, designed around the specific material, operating conditions and process goal instead of an off-the-shelf product. RATEC designs and manufactures practically anything that bulk material handling requires: from individual components such as flow channels, magnetic separators or injector nozzles to complex assemblies and complete systems that integrate into existing or new plants. This is based on in-house engineering – from consulting and feasibility studies to detailed design – combined with in-house manufacturing in St. Veit an der Glan, Austria, from one-off units to small series.
Why choose a custom component instead of a standard solution?
Because every application in bulk material handling is different, and a component designed exactly for the material, operating conditions and process goal works more reliably than an adapted standard part. RATEC custom components are designed to integrate seamlessly into the existing plant and run reliably; experience in the chemical, food, building materials and energy sectors stands for high operational reliability and robust, low-maintenance designs. Engineering and manufacturing come from a single source. Special designs to customer specification are also available across RATEC’s product groups – big-bag handling, sampling, pigging, fluidisation and pipe support systems.
Which custom components for bulk handling are available?
Typical custom components in bulk handling include flow channels, unloading devices, conveying injectors, magnetic separators, screens, emptying stations, airflow control systems and nozzles. RATEC’s range includes flow channels (air slides) that convey fluidisable powders and fine-grained materials without mechanical conveying elements, docking units for dust-free unloading of railcars and trucks, injector nozzles for medium-distance pneumatic conveying, magnetic separators and thread screens – static screens and screen boxes – for gravity-fed pipelines, octabin emptying devices, airflow control systems for conveying plants, Laval nozzles for high-velocity applications, and the bag dump station with integrated vibrating sieve. These are examples – RATEC builds what the plant needs.
Can custom components be integrated into existing plants – even for high temperatures, Ex areas or high throughput?
Yes – custom components are designed precisely to fit into existing or new plants, including under demanding operating conditions. RATEC implements high-temperature applications, explosion-protected areas and extreme throughput rates on a project-specific basis and designs every component around material properties, operating conditions and process goals. Magnetic separators, for example, are easy to integrate into existing systems, and thread screens are designed for gravity-fed pipelines. Where needed, RATEC Engineering supports the project with technical evaluation, risk and safety analysis and CAD design, from basic to detailed engineering.
Does RATEC manufacture one-off units and small series?
Yes – custom components are usually built as one-off units or in small series rather than mass-produced. RATEC manufactures customised special solutions from single units to small series in its own facility in St. Veit an der Glan, Austria. The company emerged from an engineering office for mechanical and plant engineering, so design and manufacturing come from a single source. Production is certified to ISO 9001:2015, EN 1090-1 and EN ISO 3834-2, the latter covering quality requirements for welding. If required, RATEC Engineering also handles procurement, expediting and schedule and cost control.
How can octabins, railcars or trucks be emptied dust-free?
Octabin emptying devices vacuum or dump the bulk material from octabins without supervision, while docking units serve as unloading devices for railcars and trucks and enable dust-free material transfer. RATEC builds both as custom components adapted to the specific requirements. For big bags, RATEC offers a dedicated range of filling and discharge stations, docking units and crossbars, and for bags the bag dump station with integrated vibrating sieve, which breaks up lumps before the process. Further downstream, magnetic separators or thread screens can be integrated into the gravity line to remove metallic contaminants or coarse fractions.
How does an enquiry for a custom component work?
Start with a short description of the task: which bulk material, which process step (conveying, unloading, separating, metering), which installation situation and which operating conditions such as temperature, Ex area and throughput – sketches, photos or drawings of the existing plant help as well. RATEC reviews the requirement, develops a proposal and supports the project from design to manufacturing. RATEC has experience in the chemical, food and building materials industries and in energy supply. In short: if bulk material handling needs it, RATEC can build it. Request a custom solution
