Product Description

Thayer Scale’s Low-Density “MXL-LD” is the only low capacity weigh belt feeder designed specifically to handle low bulk density materials. Because the weigh sensing system in the Low-Density Model “MXL-LD” is engineered exclusively for these types of materials, it can deliver consistent, accurate long term performance. Thayer Scale engineers developed the technology for reliable weigh feeding of low-density materials. In these specialized applications, our Low-Density Weigh Belt Feeders have a proven record of being significantly more reliable and accurate than “standard” weigh belt feeders.

Slack belt design for more stable accuracy

The “MXL-LD” M weigh 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 with drawl 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 immediately detected because the idling pulley stops rotating.

THAYER FLEXURE SUSPENSION SCALE

The Basic THAYER Flexure Suspension system utilizes a series of steel flexure plates to transmit gravimetric loads vertically from the load receiving element through levers to the specifically selected controls. The combination of mass counterbalancing against tare loads, frictionless flexure-mounted levers and a high resolution transducer produces a force measuring system beyond compare. Of significance is the fact that infinite weighments may be made without maintenance or calibration, regardless of atmospheric or factory conditions. In many instances, THAYER Flexure Suspension Systems placed in operation in 1950 are still working without maintenance or adjustment.

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 initiated 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.

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.
