Size Reduction Mill Monitoring

Sterling Systems & Controls, Inc. announces the availability of its new Mill Monitor. Particle size reduction equipment, also known as grinders and classifiers, reduces the particle size of dry solids. These devices are rotating machinery, and therefore, a bearing condition monitor is advantageous.

Bearing Condition Monitor

Sterling Systems & Controls, Inc. designs and manufactures the highest quality bearing condition monitor for use with high-speed mills or classifiers. Various standard and optional features are available, including a choice of intrinsically safe bearing sensors for equipment located in hazardous areas. Intrinsically safe sensors are intended for use in Class I, Div. 1, Groups A, B, C and D, Class II, Div. 1, Groups E, F and G, Class III, Div. 1, Ex ia IIC T4 Ga, Ex II 1 G and Class I Zone 0 AEx/Ex ia IIC T4 Ta = -50°C to 120°C hazardous areas.

Standalone and Integrated mill monitoring is available. The Control Panel for the Standalone Mill Monitor systems is the most common and is a NEMA 4X Fiberglass Enclosure with front door window kit and includes:

  • Intrinsically Safe Barriers (if applicable) for accelerometer and temperature sensor outputs
  • Digital Display Relay Modules & Display Controllers
  • Clearly labeled and secure screw-type terminals for all external connections

Integrated systems are custom-engineered and manufactured and integrated into overall factory-wide automation systems.
