Quarry and Aggregate

Hycontrol has worked with quarry and aggregate producers since the beginning and our knowledge of the sector is unrivalled. Common applications in this sector include:

  • Silo protection for cement and other powdered product
  • Level measurement throughout sites, including screen-houses, filler silos, gas and fuel oil tanks, and bins
  • Point-level switches
  • Bitumen safety systems
  • Alarm panels
  • Blocked chute detection
  • Flow and no-flow monitoring
  • Remote monitoring
 

 

Application: Powdered Product Silo Protection

Ready-mix, concrete and block works have silos on site that are pneumatically filled from road tankers. Many of the sites have silos fitted with pressure relief valves as their only protection from over-pressure. They can be rendered completely ineffective by constant use and poor maintenance. Pressure relief valves are continuously relieving pressure without the reason being investigated or the cause eliminated. Road tankers are capable of blowing product into the silos at pressures as high as 2.0 bar. The silo, however, is not a certified pressure vessel and is at risk of rupture at any pressure above 1 psi. The lack of an effective silo protection system that provides automatic closure of the delivery valve has resulted in silos being ruptured and filter systems being ejected from the silo roof. This is why the MPA recommends the installation of appropriate silo protection equipment.

Hycontrol has pioneered safety equipment in this area and is the only silo protection manufacturer whose systems not only meet but exceed guidance from the MPA. We have worked for years to raise awareness of this issue. Various resources on this topic are available both on this website and www.siloprotection.com. Hycontrol also runs informative day-courses to educate customer staff and managers - please contact us for more information.
