It’s important to understand how to get the best from your Dynamic weighing.

In dynamic weighing applications it’s vital to ensure the material travels over the belt scale or feeder with minimal vibration and movement, thus reducing errors and improving accuracy. Rotating rolls can have a major effect on accuracy if they are not the correct specification. As part of the overall system, weigh rollers are fitted with Inline idler frames to ensure the best possible accuracy can be attained.

WEIGH ROLLERS AS A SOLUTION

Weigh quality rollers are vital part of the Belt scale and feeder applications to ensure minimal vibration and provide maximum accuracy and repeatability.In addition to this it’s vital to ensure the weigh area is level before, on and after the weighing system.

The following applications would benefit from weigh rollers and inline idlers

  • All new Belt scale and feeder installations
  • Existing Belt Scale and feeder applications with or without existing weigh rollers or and inline idlers
  • Existing applications with weigh rollers over 12 months old should be checked ,*aligned and replaced if required to ensure continued accuracy

Service and Alignment

Along with the use of weigh rollers and inline idler frames, all dynamic weighing applications need regular alignment, system checks and calibration to maintain accuracy.

The benefits of weigh rollers and Frames

Weigh quality rollers and weigh frames are specifically designed to maximise the accuracy of a beltscale or feeder install.

Features and Benefits

  • Maximum imbalance of 0.014 Nm/Roll and balance quality G16 as per ISO 1940-1
  • In addition to this the shafts include stainless steel screws to allow for adjustment
  • These rolls can also be used in conjunction with cams on the idler frame on any belt scale system
  • Standard roll sizes: 102mm, 114mm, 127mm, 152mm, 178mm
  • Roll materials: Steel, PVC, HDPE, Composite, Aluminium
  • The stiffened inline weigh frames are designed to minimise deflection and efficiently direct the load through the scale frame.
