Building Materials
Bitumen is an important ingredient in asphalt production. It binds stone aggregates together to form the finished asphalt. To enable cost-effective asphalt production, reliable level measurement and overfill protection in the storage tank is required.
Building Materials
After crushing and screening, the different aggregates are transported via conveyor belts and distributed among the silos. Before further processing, the stones, gravel or rock flour are stored in buffer and production silos. To ensure optimal material storage, a precise level measurement is required.
Building Materials
After being crushed, screened and sorted into different grain sizes, the gravel and sand are transported on conveyors and stored in large stockpiles. To automate the stockpiling levels and enable the optimum area to be filled, a reliable level measurement is essential.
Building Materials
Before further processing, the cement is stored in tall silos. The cement is transported both in and out of the silo via pneumatic conveying. Efficient storage and transport of the product is ensured by accurate level measurement and point level detection, as well as also monitoring the pneumatic conveying system pressure.
Building Materials
Bulk aggregates are fed into production processes via conveyor belts or screw conveyors. For effective feed control to and from these processes, or inter-production unit billing, the mass flow of the conveyed bulk material must be measured. A reliable belt-weighing scale system and mass flow rate ensures accurate measurement and smooth operation of the plant.
Building Materials
The transport of coarse and fine bulk solids within a stone processing facility takes place in most cases via conveyor belts. To achieve an even throughput and compensate for volume fluctuations during transport, belt transfer points are integrated in the conveyor line. The incoming bulk material is briefly stored in a buffer silo to prevent belt overfilling. This is the point where the level and the point level must be monitored.
Building Materials
Large boulders are loosened from the solid bedrock through blasting. Further steps are then required to process the rock into basic building materials such as crushed rock, gravel or sand. The large stones are crushed into different grain sizes by jaw and roller crushers. To enable economic operation and keep wear and tear on the crusher to a minimum, level measurement and limit level detection are required.
Building Materials
To ensure continuous production, even if material production is interrupted, the raw materials are stored in large bunkers with heights of over 30 m and diameters of up to 20 m. The large dimensions of the silos require the filling and emptying to take place at multiple points. Uniform filling and emptying of the bunkers is achieved through level measurement at various points in the bunker.
Building Materials
A lime kiln is used to produce quicklime through the calcination of limestone. Here the furnace is filled from the top and the calcined limestone (quicklime) is collected at the bottom of the furnace. Accurate level measurement ensures optimal charging and hence efficient operation of the furnace.
Building Materials
After the calcined lime is cooled, it is sorted into different sizes and stored for further processing. Most of the lime is further processed to lime powder. For optimum production planning, a reliable level measurement is a must.
Building Materials
Materials such as concrete and mortar are needed in widely different compositions depending on the application. The various raw materials are stored in segmented towers, which then blend cement, lime and other aggregates according to specific requirements. In each individual segment, reliable level measurement and point level detection ensure the constant availability of the raw materials and cost-effective operation of the plant.
Building Materials
Diesel is stored in tanks on construction sites to supply the construction vehicles with fuel directly on site. A sufficient supply of diesel fuel is essential for optimal construction site operation. Exact level measurement, in combination with wireless data transmission to a central location, ensures automatic, optimal provisioning of mobile containers at all times.
Building Materials
Safe filling and timely routing of tanker trucks is essential for reliable bitumen supply. The medium is hot and viscous and places high demands on both handling and safety. Accurate level measurement, in combination with wireless data transmission to a central location, guarantees optimal automatic refilling of these mobile containers.
Building Materials
During the winter season the highways and road maintenance departments safeguard the roads, public squares and pedestrian paths by clearing off snow and ice. The quantities of road salt required are stored in silos and when needed, loaded onto snowploughs. Reliable level measurement is necessary for the optimal and adequate stocking of the salt. The stock level information is transmitted to the central control centre.
Building Materials
Different qualities are required from the asphalt depending on the usage and climatic conditions, so every asphalt mixture varies depending on the application. Asphalt is always extremely viscous, hot and highly adhesive. Due to these properties and the numerous different asphalt mixtures, reliable level measurement and point level detection methods are essential.
Building Materials
In the manufacture of stucco with special insulating properties, Styrofoam is also added to the traditional sand, lime and cement mixture. With a bulk density of only a few grams per litre, Styrofoam balls are extremely light and therefore very difficult to measure. For cost-effective storage, reliable level measurement and point level detection are required.
Building Materials
In order to process building materials such as mortar, plaster or grout effectively, they are delivered directly to the construction site in transport silos. There, water is added as required and the building material is processed immediately. Level measurement ensures that there is enough material in the silos.
Building Materials
Dust-free, closed loading systems are needed for fine aggregates and finished products such as cement. Automated loading of trucks is preferred in the industry and, while the load quantity is determined with a weighing system, it must be ensured that the truck is in the correct place and not overfilled. Reliable point level detection and vehicle positioning shortens loading times, increases throughput and improves the efficiency of the entire system.
