Belt scale is a kind of measuring equipment for continuous weighing of materials during the process of conveying bulk materials by belt conveyor. When conveying small materials, the belt speed is allowed to be 3.15m/s. This belt scale features accurate readings within 0.25% of test load and is repeatable to 0.125%, when properly installed and maintained to MERRICK standards. A conveyor belt's function is to move objects from Point A to Point B with minimal effort. The conveyor belt is power by a rotating cylindrical tube that spans the width of the belt.
In this case, a thorough inspection of the scale and conveyor should be done to determine the source of the error. RTI supply premium Conveyor Belt Scales (Weightometers, weighers) with models Easyweigh, Tachometer &unipro mainly for the coal, iron ore and minerals industry's. . Belt scales can even work with limited clearance around the conveyor belts allowing ease of weighing in tightly confined areas. Belt-Way's Conveyor Belt Scales can be installed on portable or stationary scales, provide quick setup, and easy calibration. Let's start by describing the three basic parts . Ideally a scale should be located 20 feet away from the tangent points of a convex curve and 40 feet from the tangent points of a concave curve. It can handle rates that make the application of differential scales almost impractical. 2 tape on the roller run together with cargo. The use of forward-inclined trough-shaped rollers also plays a role in centering the conveyor belt. 3. the load cells measure the material weight on the belt, and send a signal to the . The belt conveyors are based on the principle of material transport from the point of feeding to the point of discharge by a rotating belt driven by a motor in pulleys. It can handle rates that make the application of differential scales almost impractical.

Belt scale calibration Conveyor belt scales are normally calibrated in three steps: 1. 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. 5. As an integrating device, a conveyor belt scale is a very compact device that fits into any conveying system. A beltweigher or belt weigher is a piece of industrial control equipment used to gauge the mass or flow rate of material travelling over a troughed (cupped) conveyor belt of any length which is able to adequately contain the material being weighed. We are a large-scale manufacturer specializing in the production of various mining machinery, including different types of sand and gravel equipment, powder milling equipment, mineral processing equipment and building materials equipment. Bucket Conveyor Contamination most commonly comes in the form of product debris, worn pulley lagging, grease, and loose bolts inside of the conveyor frame. However, if the second test shows an error of 0.95% (a difference of 0.30%), the scale's calibration can be adjusted by 1.10%. Watch as one of Siemens' senior application engineers walks you through the process of performing load checks on a conveyor belt scale system, and how you can calculate the mV signal output from.
