Model MH High Capacity Weigh Belt Feeder

Feed Rate: 400 - 3,000 STPH Particle Sizes: Fines up to 6" Densities: 40-200 lbs/ft3

First 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.

• Slack belt design for more stable accuracy
  The MH belt is driven from the head pulley located at the outlet end of the feeder, rather than the tail pulley located at the end inlet. This permits lower belt tension during operation for better sensitivity and more stable accuracy. The head pulley is crowned to prevent belt tracking problems and is sheathed in rubber lagging to prevent belt slippage.
      
• Inlet dimensions custom tailored
  Ensures uniform withdrawl of material from storage. Very careful consideration is given to density, particle size and handling characteristics of your material.
     
• Speed sensor mounted at idling tail pulley
  Measures the true speed of the belt via rotation of the idling pulley, not an inferred belt speed based on motor speed. Belt slippage or breakage is immediatly detected because the idling pulley stops rotating.
      
• Scale outside material handling area
  An idler supporting the belt (the "weigh" idler) transmits the load to the scale, which is located outside the weigh belt enclosure. This design has several benefits. The scale is not prone to damage, is out of the way for cleaning, and is not subjuct to tare build-up since material cannot fall onto the scale.
       
• Automatic calibration
  Thayer Scale's optional automatic test weight mechanism provides a means for applying a precision test weight to allow completely automatic calibration. The calibration sequence can be intiated via the weigh belt instrument keypad or via a contact closure. The need for test chains is eliminated.
        
• High accuracy,
  rugged measurement system 100% of the scale's capacity is used to weigh material. Dead weight of the weigh idler and belt is mass-counterbalanced, thus providing excellent resolution and a high signal to noise ratio. Thayer Scale's rugged load cell design assures reliable and accurate performance for the life of the weigh feeder.
      
• Screw adjustable idler alignment
  The idlers adjacent to the weigh idler are mounted on jacks for easy alignment in the field. All idlers are mounted on individual CEMA brackets, permitting removal to either side without major framework disassembly or belt removal.
     
• Full length adjustable skirt boards
  Tapered and flared from the inlet to the discharge to prevent pinching of material between the skirt and the belt. Skirt boards are located inside the belt flanges to provide two barriers to contain material and prevent spillage.
