Precast concrete equipment: what will be needed for production? The technological line includes special machines and tools that perform clear functions. Extruder - production of concrete hollow core slabs. An extruder is a machine that is used to cast a product from a concrete mixture. Production facilities at this level use large screw extruders.

After these calibration steps, the DEM parameters were validated by comparison of the mass flow rate and driving power by the batch production of screw conveying in simulations and experiments.

In the numerical simulation of the macroscopic flow of the concrete, it can optimize the performance indicators of the screw conveyor and improve the uniformity of the material to be discharged in the batch production. The discrete element method is effective. The accuracy of physical parameters of this method is a key issue for the reliability of the simulation results of …

In addition to cost and time management, quality management is one of the most important aspects that enable effective competition on the global construction market. Implementation of the quality management system should be carried out in a comprehensive approach, covering the manufacturing process, as well as cooperative processes. Among the …

Therefore, along the material flow in the process, we can also consider the presence of an information flow. Process control parameters are treated as input information to the production system, while measurements of the production system itself and individual material states are treated as output information (see Fig. 1). We define control ...

In contrast, concrete production is far more decentralised (Fig. 5), with production typically at the local level of batching plants (or pre-fabrication factories), with on-site production widespread for the informal sector in developing countries.This difference in the supply chain distribution makes changes easier to enact for a given site, but less easy to cascade horizontally along the ...

This type of concrete pump is mounted on a truck, and it is commonly referred to as a line pump or truck-mounted concrete pump. It can move to different jobsites by itself, not like a trailer concrete pump, there must be a device to tow it. For this truck-mounted concrete pump, it can move by itself. It is faster and more convenient than the trailer concrete pump.
