Cementos Cosmos to upgrade Ourense grinding plant with new compressor
28 September 2021Spain: Cementos Cosmos plans to install a new screw compressor in the cement discharge system at its Ourense grinding plant in Galicia. The producer says that the new equipment will improve the energy efficiency of the process of discharging cement from railway tanks to storage silos. The cost of the work is Euro23,500, towards which Cementos Cosmos has received a Euro8140 grant from the European Reagional Development Fund (ERDF) under its A New Way to Build Europe programme.
Germany: Beumer Group has developed a screw weigh feeder with automatic calibration. The company says it is especially well suited to exact and controlled feeding of inhomogeneous bulk materials of densities between 0.08t/m3 and 0.80t/m3 and extremely high moisture content such as alternative fuels. Its capacity is 30t/hr and its weighing tolerance is between 1% and 2%. It is completely covered to prevent dust and other environmental stresses.
Van Beek develops new Sample Screw for in-line sampling
18 September 2015The Netherlands: Screw conveyor specialist Van Beek has developed the Sample Screw in order to allow a representative sample to be taken without halting the production process.
According to Van Beek, the machine is ideal for taking representative product samples from containers, hoppers or in-line (for example, after an outlet or in a discharge pipe). Using a small screw conveyor, a sample of the material is taken safely from the product stream without disrupting the process. Even materials with poor running qualities can be controlled in this way because a screw is used.
The sampler is easy to dismantle for quick and complete cleaning. Samples can be taken of powders, flocks, granules, flakes, pellets and slurries. It can also be used in the dairy, food, pharmaceutical and chemical industry. The sample size and frequency can be adjusted.
The sampler is driven by an air motor or electric motor with gear unit. Whether this involves bunkers, silos, hoppers or bulk transfer, in most cases few or no adjustments need to be made to the existing system.
