Description

MTF Weigh Belt Low to Medium Capacity Feeder

The Model “MTF” weigh feeder is a low to medium capacity feeder that accurately and reliably measures and controls material feed rates. It is available in widths from 18” to 48”, with different belt types, standard inlet configurations and materials of construction to meet the most demanding requirements.

Each weigh belt feeder can be adapted in length and width to meet the customers’ specific requirements. Modular construction features open design or completely dust tight enclosure. Material containment is achieved using full length adjustable skirt boards installed along the entire length of the conveyor or with high side wall belts made of corrugated high-tensile rubber which provide excellent flexibility, elongation and abrasion resistance. The two options can be combined for highly free flowing materials.

An optional Thayer Scale patented ACCU-FLEX dual load-cell suspension system (scale) is sensitive for handling light loading applications in harsh environments. It is rugged, yet highly flexible.

The Model MTF includes an optimized inlet chute to achieve uniform material flow from storage bins. The correct inlet design produces maximum efficiency and low energy consumption.

ADVANTAGES

  • Open or enclosed construction
  • Modular design
  • Easy to clean
  • Easy to maintain
  • Cost-effective
  • Low to medium capacity

FEATURES

MATERIAL CONTAINMENT

FULL LENGTH ADJUSTABLE SKIRT BOARDS

Installation of skirt boards along the entire length of the conveyor totally confines the material flow channel which helps control dust. Skirt boards are tapered and flared from the inlet to the discharge to prevent pinching of material between the skirt and the belt.

HIGH SIDE WALL BELT

Corrugated sidewall belts are made of high-tensile rubber, which provides excellent flexibility, elongation and abrasion resistance. Can be combined with full length side skirts for highly free flowing materials.

INLET CHUTE

Inlet chutes are a major factor in achieving uniform material flow from storage bins. Careful consideration is taken in the design of the inlet section based on a given material density, particle size and handling characteristics. The correct inlet design produces maximum efficiency and low energy consumption.

PATENTED ACCU-FLEX SCALE

Thayer Scale’s patented ACCU-FLEX suspension system (scale) is sensitive for handling light loading applications. Flexure based design extremely robust, is not prone to damage, is out of the way for cleaning, and is not subject to tare build-up causing incorrect calibration.

AUTOMATED TEST WEIGHT LIFTER

An optional Automated Test Weight Lifter (ATWL) mechanism provides a means for applying a known test weight to allow completely automatic calibration. The calibration sequence can be initiated via the weigh belt instrument keypad or via a contact closure. A self-checking software algorithm in the weigh belt instrumentation prevents erroneous calibration. Test weight calibration eliminates the need for test chains.

BELT TRAVEL PULSER

Rugged speed sensor is coupled directly to the feeder tail pulley not the drive pulley and measures belt speed or belt travel.

WELDED FRAME, QUICK REMOVAL ACCESS PANELS

The Thayer Scale Model MTF weigh belt uses a rigid, box frame construction to resist deflection and deformation under heavy loads. Frame distortion adversely affects scale measurement performance.

Removable covers provide easy access, designed to meet EPA and OSHA standards. Side panels, if included, are removed with quick-release fasteners (no tools required).

DRIVE SYSTEM

Head and tail pulley are selected in accordance with CEMA standards, with lagging as required. Direct or chain drives are available.

SLACK BELT DESIGN

Low belt tension increases belt life, produces more stable measurement and eliminates the need for belt tracking devices.
