Switch cabinet construction

Independent electrical system planning & customised switch cabinet construction Our company takes care of the entire electrical system planning process. Starting with the analysis of your requirements, through the creation of detailed circuit and wiring diagrams, to implementation. We rely on our own planning expertise: each system is planned individually and tailored precisely to your requirements. We then construct the switch cabinets in our workshop, naturally in accordance with the plans drawn up beforehand. This integrated process of planning and manufacturing provides you with a system that is optimally tailored to your operating conditions. Thanks to our approach, we offer tailor-made solutions for every problem: whether you have special requirements in terms of performance, safety, space or future expansions, we have the right solution for every challenge. Our customers benefit from the fact that our control systems are transparent, safe and efficient. Individually manufactured control cabinets — with the right choice of components, clean wiring and a well-thought-out layout — make maintenance, expansion and adaptation of your system much easier and more reliable later on. You can rely on our experience and commitment: we don't deliver off-the-shelf solutions, but solutions that are tailored to your needs — individual, safe and practical.

Control and measurement systems

Automated, Reliable, Future-Proof Whether level, weight, pressure, or limit detection – our measurement and control systems perform key functions in monitoring your bulk material processes. Radar Sensor Radar sensor technology enables precise measurement of silo filling levels. Using our Siltronic control systems, the material volume and weight (calculated via bulk density) inside the silo can be determined. SiloPilot The SiloPilot provides accurate level measurement in our silos. Through our Siltronic control systems, the material volume and weight (based on bulk density calculation) can be determined. Weighing System The weighing system ensures continuous and precise weight measurement. Silo contents can be optimally documented via an interface within your ERP system. Rotary Paddle Level Switch – Full Detector The full detector reliably signals when the maximum filling level in the silo has been reached. This signal allows, for example, truck filling operations to be stopped at an early stage. Rotary Paddle Level Switch – Empty Detector This sensor detects limit levels, such as empty level indication. This important information prevents material shortages within the system. Vibrating Fork Level Switch – Empty Detector This device also detects limit levels for empty level monitoring, helping to avoid material shortages in production processes. Pressure Sensor In our systems, pressure sensors are primarily used to monitor pressure within conveying lines. Since excessive filling pressure can damage certain materials, monitoring is essential. During truck filling, warnings can be issued if filling pressure becomes too high. In pressure conveying systems, the pressure sensor also enables optimal adjustment of conveying performance.

Automatic bag emptying station

Efficient. Reliable. Powerful. This system allows you to empty 25 kg plastic bags fully automatically. Pallets with a maximum of 11 layers of 5 bags each can be accommodated.

An octabin container is then positioned upside down over the octabin, pressed down and then turned 180°. After the turning process, the octabin container is removed with an industrial truck and transported to its destination. In this way, the bulk material can be emptied completely and without contamination.

Conveyor systems / conveyor technology

Modern conveying technology connects storage, production, and logistics into an efficient material flow. Various conveying systems enable clean, economical, and product-friendly transport of bulk materials and can be flexibly integrated into existing processes. Pressure conveying is particularly suitable for the internal transport of large material quantities. The material is metered into the conveying line via a rotary valve and transported, for example, into silos using conveying air. High conveying capacities and optional automation enable continuous processes and targeted distribution to different storage containers. Screw conveyors are mainly used for mixing and precise dosing of bulk materials. Different sizes, drive systems, and steel or stainless-steel designs allow optimal adaptation to various applications, ensuring reliable and economical conveying performance. The flexible spiral conveyor enables dust-free, segregation-free, and especially gentle conveying of sensitive materials. Flexible system layouts, simple installation, and low noise emission increase operational efficiency. Conveying capacities of up to 20 m³ per hour and long conveying distances provide additional application possibilities. In vacuum conveying, a vacuum system generates negative pressure that draws in the material and transports it to a cyclone separator. This process ensures clean, flexible, and efficient material transport for a wide range of industrial applications.

Daily silos

Daily silos serve as production-related storage units and ensure that your material is available exactly where it is needed – in precisely the quantity and quality required by your daily process. Your advantages with daily silos from Eichholz 1. Production reliability on a daily basis Daily silos store exactly the amount of bulk material required for a defined production period – typically a shift or a day. 2. Optimal integration into production lines Daily silos are placed directly at or above the consumption process. This results in: • Short conveyor distances • fast replenishment • minimal losses • energy-efficient material flows Ideal for grinding mills, dosing lines, mixing plants, presses, extruders and many other applications. Areas of application: • Plastics industry • Recycling industry • Chemical industry • Pharmaceuticals • Logistics industry • Automotive • Food industry Technical data: Storage volume: up to 100 m³ Special dimensions on request Material: Aluminium: EN AW-5754 (AlMg3) Stainless steel: 1.4301/1.4404 Bulk density: up to 20 kN/m³

Mixing silos

Homogeneous. Precise. Process-reliable. Mixing silos combine storage and homogenisation in a single system. They ensure that bulk materials are always mixed homogeneously, free-flowing and ready for processing. Variant 1: Mechanical mixing screw The vertically installed mixing screw ensures maximum mixing accuracy with particularly gentle product handling. • Open or closed design • Suitable for sensitive, fine-grained or homogeneous mixing tasks • Available as an internal or external silo • Volume range: 5 m³ – 120 m³ This variant offers controlled, intensive mixing – ideal when optimum homogeneity with short mixing times is crucial. Variant 2: Static mixing tube In mixing silos with a central mixing tube, homogenisation is achieved through intelligent stratification and extraction: • Different batches that are filled in succession are discharged again in mixed order via openings in the mixing tube • Particularly suitable for continuous processes and frequently changing batches • Very low maintenance, as there are no moving mixing elements (static mixer) This technology ensures reliable mixing solely through material flow and gravity – ideal for robust, low-maintenance processes. Variante 3: Static mixing cone Mixing takes place through the simultaneous flow of material from different silo areas • No moving parts, therefore extremely low maintenance • Suitable for large storage quantities and varying bulk materials • Volume range (mixing pipe/mixing cone): 10 m³ – 400 m³ This variant uses targeted flow paths to produce a homogeneous mixture – ideal for large silos and robust bulk materials.
