Constant Feed Weigher

SITRANS WW100

Overview

SITRANS WW100 is a high-accuracy, low-capacity weighfeeder used for minor ingredient additives.

Benefits

  • High accuracy
  • High turn down ratio 100 … 10 % of capacity
  • Corrosion resistant components
  • Fast and easy belt removal for replacement or cleaning
  • Simple installation, easy to clean and maintain
  • Pre-programmed drive for servo motor control

Application

SITRANS WW100 is one of the most accurate in-motion weighing systems on the market. It is specially designed for high accuracy on light loading processes. The design eliminates material buildup to ensure accurate, reliable measurement.

The unique long length platform weigh bridge mounts directly to a corrosion-resistant platform load cell. An adjustable mechanical shear gate profiles the material and fixes the correct material bed depth for a given material particle size. The belt speed can be automatically adjusted to attain the correct feed rate.

Standard components include an anti-static food grade belt, gravity tensioned roller, tail pulley driven belt for maximum weighing accuracy, belt tracking rollers, belt scraper and plow for self-cleaning.

SITRANS WW200

Overview

SITRANS WW200 is a low-to-medium capacity weighfeeder used for minor ingredient additives.

Benefits

  • High accuracy
  • Ideal for low-to-medium capacity loads
  • Fast installation, easy to clean and maintain
  • Flexible, rugged design allows configurations to suit many applications
  • Quick delivery on standard units
  • Outboard mounted load cells with protective cover

Application

SITRANS WW200 has been field tested and proven in hundreds of applications.

The unit can be customized to meet exact application needs. Stainless or mild steel units are available in open or enclosed styles. Custom lengths, belt types, inlet configurations, drives, and other options are available to meet your requirements. The MS (mild steel) model is ideal for use with chemicals, powders, or any granular product in applications not requiring washdown. The SD (sanitary duty) model is designed for the food industry where high pressure wash-down is required. It meets all USDA and FDA requirements.

Its cantilevered mechanical design provides for quick belt removal and easy maintenance. It is designed to eliminate material build-up, ensuring high accuracy and reliability. The unique weigh system reduces dead load and applies live load directly to two platform load cells. Load cells are externally mounted for easy access and maintenance.

Standard components include an anti-static food grade belt option, horizontal slider bars for self-cleaning and minimal product build up, belt tracking rollers, belt scraper, and plow for selfcleaning.

SITRANS WW300

Overview

SITRANS WW300 is a medium- to high-capacity weighfeeder used for macro ingredient additives.

Benefits

  • Rugged, durable design for heavy-duty applications
  • Handles medium- to high-capacity loads
  • Standard mild steel open or enclosed construction
  • Heavy-duty 102 mm (4 inch) diameter idlers
  • Large 203 mm (8 inch) minimum diameter head and tail pulleys for maximum traction
  • Patented design
  • Easy to replace endless belt
  • Gravity tensioned belt cleaner
  • Fast installation, easy to clean and maintain
  • Outboard mounted load cells with protective cover

Application

SITRANS WW300 is designed for industrial applications such as mining, cement, chemical processing, pulp and paper, and other heavy-duty industries.

Field tested and proven in hundreds of applications, it enhances profitability by ensuring accuracy, enhancing blend consistency, reducing downtime, and improving accountability and record keeping. The unique weigh systemreduces dead load and applies live load directly to load cells for accurate measurement. The dual load cells are externally mounted for easy access and maintenance.

It is available in a variety of lengths from 1.6 m (63 inch), belt widths from under 0.5 m (18 inch) to 1.8 m (72 inch), several different inlet configurations and materials of construction. It can be configured to suit various applications.

Standard components include CEMA C rated idlers, belt tracking rollers, hinged access panels on enclosed units, integral lifting points for easy installation, a belt scraper and plow for selfcleaning.

Overview

Milltronics BW500 is a full feature integrator for use with both belt scales and weighfeeders.

Milltronics BW500/L is an integrator for use in basic belt scale or weighbelt applications.

Benefits

  • Automatic zero and electronic span calibration
  • Alarms for rate, load, speed, or diagnostic error
  • On-board Modbus, optional PROFIBUS DP, ProfiNet, Modbus TCP/IP, EtherNet/IP, and DeviceNet
  • Comprehensive weighfeeder control functions
  • PID control and on-line calibration with optional analog I/O card
  • Differential speed detection with second speed sensor
  • Moisture meter input with optional analog I/O card for calculation of dry weight
  • Inclinometer input with optional analog I/O card to compensate for conveyor slope
  • Suitable for belt scale custody approval
  • Measurement Canada, OIML, MID, GOST, and NTEP approved

Application

Milltronics BW500 and BW500/L operate with a belt scale and a speed sensor. Belt load and speed signals are processed for accurate flow rate and totalized weight of bulk solids.

BW500 can take on lower level control functions traditionally handled by other devices, and it supports popular industrial communication buses. Its proven load cell balance function eliminates matching of load cells.

The PID function may be used for rate control on shearing weighfeeders - where belt loading is constant - but can also control pre-feeding devices. Operating in tandem with two or more weighfeeders, the BW500 may be used for ratio blending and controlling additives. Batching, load out, and alarm functions are also provided by the BW500.

Dolphin Plus software may be used for programming the unit on a PC.
