HEAVY INDUSTRY MODEL M WEIGH BELT FEEDERS

Thayer Scale MH Weigh Belt FeederFirst designed for steel mill service to feed flux materials (limestone, mill scale, dolomite, iron ore pellets, fluorspar and coke), the Model “MH” has been subjected to extreme environmental conditions-such as abrasive dusts, corrosive fumes, wide temperature fluctuations and vibrations-without any detrimental effects on performance or accuracy. Its rugged construction coupled with the most advanced electronic controls make it truly THE WORLDS MOST RELIABLE WEIGH FEEDER.

Thayer MDH weigh belt feederOriginally designed for steel mill service, Thayer’s Weigh Belt Model MDH benefits put it into a class by it self. The Model MDH offers an extremely robust design with an intense commitment to quality and attention to detail. With over 50 years of weigh belt experience THAYER produces a weigh belt that is highly accurate, rugged and dependable. THAYER feeders are built to endure the rigors of high capacity feeding and heavy density materials ranging in particles sizes from fines to 6 lumps. The bottom line of using a THAYER Model “MDH” in your process translates into reduced operating downtime, lower overall cost and quick return on your investment.

Thayer MD weigh belt feederThe Model MD is an extremely rugged weigh feeder that was originally designed for the harsh environment of the cement industry but can be used in a wide variety of applications. The Model MD is the ideal weigh feeder when medium to high feed rates are required, handling high bulk density and small through large particle size materials. The Model MD can be subjected to extreme environmental conditions such as abrasive dusts, corrosive fumes, wide temperature fluctuations and vibrations-without any detrimental effects on performance or accuracy.

Thayer MDL weigh belt feederThe Model MDL bridges the gap between standard low capacity and high capacity weigh feeders. Some materials are too abrasive for standard low capacity feeders, lump sizes can be too large or flow rates slightly exceed specified limits, resulting in low accuracy and constant maintenance problems. These applications often can’t be reliably handled by larger, high capacity weigh feeders because the relatively low flow rates fall below specified limits. (for example: feeding 1.5 lumps of coal @ 2 STPH). The Model MDL is as ruggedly built as our capacity weigh feeders, to withstand abrasive materials, but is designed to operate at flow rates just beyond the limits of our low capacity feeders.

Thayer Scale Low M weigh belt feeder for low density products.One of Thayer Scale’s specialty equipment lines is the Model “M” Low-Density Feeder line for weighing bulk materials having densities under 10 lb/ft³. A conventional feeder capable of weighing heavier products (typically 50 lb/ft³ and above) to an accuracy of ½% under limited weekly calibration attention, is likely to achieve no better than 3-4% accuracy when weighing a material having a density of only 5-10 lb/ft³.

Thayer Scale MWF weigh belt feederModel MWF is a widely recognized general purpose low capacity weigh belt feeder designed to operate accurately and reliably in harsh industrial environments with minimal maintenance. It can be used with an open loop belt drive to gravimetrically measure the flow of material, or with closed loop control to operate as a feeder and regulate the flow to a constant or dynamic set point.

Thayer MWF-OS sanitary weigh belt feederThe MWF-OS Sanitary Open Construction Weigh Belt Feeder provides Thayer Scale accuracy, ruggedness, and reliability. Self cleaning pulley eliminates material build-up and belt tracking problems. Unique flared skirt design prevents material spillage and assures proper feed control. Rigid scale support system provides exceptional stability, assuring accuracy without frequent recalibration.

Thayer Scale MXL weigh belt feederThayer Scale’s Model “MXL” is a widely recognized general purpose low capacity weigh belt designed to operate accurately and reliably in harsh industrial environments with minimal maintenance. It can be used with an open loop drive to gravimetrically measure the flow of material, or with closed loop control to operate as a feeder and regulate the flow to a constant or dynamic set point.

Thayer MXL Low Density weigh belt feederDesigned exclusively for accurate and reliable feeding of materials with very low bulk densities such as wood flakes and fibers, snack foods, textiles and tobacco products. The MXL “Low Density” Weigh Belt Feeder incorporates the following unique design features that result in high accuracy, reliable performance and stable calibration.

Thayer SB Insertion weigh belt feeder scaleSimplified construction and calibration results from suspending a complete synchronous-speed conveyor from a Thayer Flexure Scale. The type ”SB” weigh belt feeder adapts well to existing vibratory feeder, screw feeder or belt conveyor installations where it has been determined that weight measurement and/or flow control is desired. Also on new installations, the combination of a suitable pre-feeder and type SB unit often proves the best approach considering both cost and material handling.

Thayer Scale SB Insertion weigh belt feederThayer Scale’s Weigh Belt Feeder Series “SI” Insertion Weigh Belt Module is a unique feeder that has been designed to easily fit into an existing belt or vibratory conveyor line. The “SI” comes in either scale over or scale under design. A short support framework and a V-Guided conveyor (12, 18 and 24 wide) makes this the only practical weighing module for insertion into a transition space between existing conveyors or equipment.
