Mining and Quarrying Industry

For monitoring and maintaining pumps, crushers and conveyors

Specifying a Vibration Sensor

Within the coal, mining and quarrying industries, it is common for machinery to run 24/7, often under extreme environmental conditions, with high levels of dust, moisture and temperature, and in areas where access for maintenance or repair is difficult.

With machine downtime costing many thousands of dollars per hour, and with machine failure representing a safety risk, it is crucial that the rotating parts of machinery are continuously monitored as part of a predictive or preventative condition monitoring programme.

Vibration monitoring is key to the success of a preventative maintenance programme. Its use has been accepted and proven for the detection of faults that include bearing wear, misalignment of shafts and out of balance fans.

At Hansford Sensors we manufacture a full range of vibration sensors to help your business meet the challenges of monitoring and maintaining a wide range of machines used in quarrying and mining, including motors, gearboxes, pump, screens, crushers and conveyors.

Factors to consider

Selecting the best accelerometer or vibration sensor for kiln drives, crushers, screens, conveyor belts, raw mills, elevators, separators and blowers, depends on a number of factors. These include::

  • Availability of the plant
  • Cost of breakdown
  • Criticality of the machine/impact on the production process
  • Access to machine, guarding, health and safety implications
  • Environmental factors

We can provide solutions for both online and offline monitoring, with all our industrial accelerometers being designed for use in the toughest environments, including hazardous areas.

Typical solutions for the Mining and Quarrying Industry

High Sensitivity & Intrinsically Safe

Options for all our accelerometers for mining and quarrying include armoured or braided cable, plus quick release 2 Pin MS connectors, IP66 and IP68 cable assemblies, and stainless steel enclosures.

Monitoring Imbalance

Our 4-20mA vibration sensors and 0-25 mm/s RMS velocity sensors (HS-420 Series) are designed for connection to PLC (programmable logic controller) or similar systems. This is an ideal solution for monitoring imbalance on rotating fan and motor shafts. Similarly, our 0-2g RMS acceleration 4-20 mA sensor (HS-422 Series) offers an excellent option to protect conveyors between routine surveys.

Restricted Access

For applications, such as crushers, screens, conveyor pulleys and drives, and where access is restricted, we provide side-entry and low profile accelerometers. These sensors are also ideal for areas where debris or dust would otherwise affect the performance of a top entry device.

Extra Options

Options for all our accelerometers for mining and quarrying include armoured or braided cable, plus quick release 2 Pin MS connectors, IP66 and IP68 cable assemblies, and stainless steel enclosures.
