So what is a belt scale? A belt scale is a weigh in motion scale that is used to continuously measure material flow rates and totalize material amounts being transported on a conveyor belt.
Belt scales are an integral part of most bulk material handling facilities. Belt scale systems monitor raw material feed to crushers, mills, screens, boilers, preparation plants, and coal-fired power plants to ensure process material feed rates and maintain overall quality.
Belt scales are used in production and logistics, for measuring throughput and consumption in production plants, internal balancing of supply and discharge, load limit signaling, and batching at loading stations or metering hopper control. Belt scales provide vital information for the effective management and efficient operation of your business. The material weight is determined by weighing the belt load and incorporating other factors such as the belt speed and belt length.
Most belt scales on the market today are rugged and dependable. They often come as a single, dual, or four idler scale – in general the more idlers, the more accurate your scale is going to be. Many manufacturers offer self-storing calibration weights to make routine calibrations and checks quick, safe and simple.
