SOLIDTEC

Aggregate bins

SolidTec aggregate bins, also referred to as aggregate storage hoppers or aggregate silos, are fully automated industrial devices designed for precise weighing, batching, and distribution of a wide range of bulk materials. As the SolidTec brand, we deliver not only complete concrete batching plants but also standalone, highly advanced raw material storage and feeding systems. Our bins stand out due to their large operational capacity, strict batching accuracy, and the highest execution quality, which guarantees reliability and operational stability for the entire technological production line.

The primary goal of SolidTec is to deliver solutions ideally tailored to the individual needs of the investor. We design devices to fit perfectly within the spatial limitations of the facility and to be fully compatible with the client's current machinery park. To make this possible, we offer over 120 diverse technical configurations. These include compartment capacities ranging from 8 to 30 m³ and modular configurations consisting of 1 up to 4 charging hoppers. The width of the loading walls ranges from 2.5 to 4 meters, allowing trouble-free and safe interaction with wheel loader buckets of various dimensions, while the front wall height ranges from 3.2 to 3.92 meters.

Thanks to its universal and reinforced design, SolidTec equipment finds wide application not only in classic ready-mix concrete plants but also in continuous mixing plants and other branches of industry. These systems successfully serve the precise batching and distribution of all types of bulk materials, ensuring full automation and repeatability of production processes.

Batching system

We build our aggregate batching and weighing systems in two proven technical architectures tailored to the specifics of a given project. The first option features advanced bins based on a so-called weigh belt. In this solution, the entire batching belt conveyor is suspended on 6 "S-type" load cells working in a high C accuracy class, which allows for weighing raw material with an accuracy up to 4 kg. The second alternative, ideal for specific technological layouts, consists of charging hoppers equipped with independent intermediate weigh hoppers. These are suspended directly under the hopper itself and above the collecting belt conveyor, ensuring excellent vibration isolation and measurement precision.

The reliability and dynamics of the transport system are guaranteed by optimally selected drive units. In configurations intended for smaller concrete batching plants, we use high-quality Italian motors with a power of 7.5 kW paired with durable Polish gearboxes with a rotational speed up to 1440 RPM. For larger plants with increased output and heavier duty cycles, we offer more powerful 11 kW motors that guarantee trouble-free startup of the belt conveyor even under a full load and difficult weather conditions.

Pneumatics

The heart of the pneumatic system in SolidTec installations consists of reliable, three-piston oil compressors powered by a 400V supply. They are responsible for generating and maintaining a stable working pressure, which is essential for efficient and repeatable control of the actuators across the entire production line.

Tailored capacity: We offer a 500L oil compressor (3 pistons / 400V) to support the entire concrete batching plant or a 300L oil compressor (3 pistons / 400V) dedicated to the independent power supply of the charging hoppers alone.
Ergonomic design: In the case of a standalone bin configuration, the compressor is compactly mounted on a dedicated shelf made of heavy-duty angle irons, located at the very end of the belt conveyor structure.
Armored cylinder execution: Compressed air powers linear pneumatic cylinders with an 80x300 SC drive, which are responsible for the smooth opening and closing of heavy charging hopper discharge gates and – in the option with intermediate weigh hoppers – the discharge gates of the scales.
Full dynamic control: The entire system is controlled using reliable solenoid valves equipped with throttles. This allows for precise, mechanical regulation of the gate opening and closing speeds, which directly translates into the dosing accuracy of aggregate fractions.

Short specification

The aggregate transport system in SolidTec systems relies on an armored, perfectly balanced belt conveyor designed to operate under extremely harsh conditions and under constant, high working loads.

Vulcanized 800b belt: The use of a glued and vulcanized belt with a width of 800 mm guarantees maximum resistance to stretching and mechanical damage caused by the sharp edges of crushed fractions.
Independent tension adjustment: The tail pulley acts as a tensioning system, allowing the operator to quickly, precisely, and fully independently correct belt tension using take-up screws.
Reinforced idlers: Trouble-free operation under full load is ensured by reinforced idlers based on up to 4 self-lubricating bearings, completely resistant to cement dust and moisture.
Crowned pulleys: The main conveyor pulleys are precisely machined in a barrel shape, which forces natural, automatic centering of the belt along the axis of the supporting structure.
Lateral track stabilization: The use of dedicated lateral tracking rollers eliminates the risk of the belt drifting to the sides, protecting its edges from rubbing against the frame structure.

Electric vibrators

The vibration system proves indispensable in difficult weather conditions and when working with demanding raw materials. When aggregate is highly damp or freezes during the winter period, it has a natural tendency to stick to the steel walls of the compartment, bridging and creating dangerous blockages. The high-frequency vibrations generated by the device effectively break up the compact structure of the material and eliminate static friction, guaranteeing smooth descent and full production continuity regardless of the weather conditions prevailing on the construction site.

Reliable OLI electric vibrator: As standard equipment, we install a device from the renowned Oli brand (model MVE 300/3E – 30A0), which effectively prevents material blockage and facilitates smooth emptying of the sand compartment. Depending on production specifics, it is possible to install additional vibrators on the remaining compartments of the bin.
Integrated operation with gates: The vibration system is fully synchronized with the opening system of the discharge gate of the given bin. The device activates automatically only during material discharge, which optimizes the weighing process, prevents aggregate compaction when the gate is closed, and reduces noise.
Mechanical intensity regulation: The design of the electric vibrator allows for precise adjustment of the centrifugal force to match the moisture level and fraction of the material. Adjustment is done mechanically by changing the position of the adjustable eccentric weights beneath the motor covers.

Safety

Maximum operational reliability and strict compliance with safety standards are the foundations on which the design of SolidTec equipment rests. Every element exposed to external factors or industrial interference has been properly protected to ensure production continuity without unplanned downtime.

Shielding and signal protection: All load cells are connected using professional shielded cables. This effectively insulates the measurement system from any electromagnetic interference generated by the power grid, inverters, or the operation of other plant machinery, guaranteeing consistent weighing precision. Additionally, all wiring is routed in tight conduits that protect the cables from moisture, cement dust, and mechanical damage.
Safety guarding with quick access: HSE safety along the entire length of the belt conveyor is ensured by a robust safety mesh with a dense 40x40 mm mesh size, preventing accidental contact with moving drive components. The design of the guards was developed with service ergonomics in mind – an intuitive and easy removal system allows for instant dismantling of the mesh, enabling express access to the idlers and pulleys during periodic maintenance work.
