Description

The EBW 20-SC is a two-idler belt scale for small belt conveyors with belt widths up to 800 mm and flow rates up to 400 t/h. This belt scale can be used for almost every conveyor. The longer load carrier ensures in a much higher measuring accuracy compared to single-idler belt scales.

Typical applications of the EBW 20-SC are stationary belt conveyors and legal-for-trade applications. The belt scale is used for precise weighing and dosing of bulk materials, e.g. fuel surrogate or even for a low flow rate. Also, it is suitable for exact weighing of grain and animal feed, plastics, wood pellets, in the recycling industry and waste management and in the pit and quarry industry.

 

The belt scale EBW 20-SC has a simple mechanical design that is optimally for use in small belt conveyors. The load carrier is designed for two idlers. The weighing frame is supported by two spring steels and by one load cell. The belt scale has a low installation height, which allows the use in belt constructions with a small interspace between upper and lower belt.


The weighing frame of EBW 20-SC is equipped with a precise stainless steel load cell with OIML approval in class C3. The load cell is secured by a transport and overload protection.

 

As standard, the belt scale is made of angle steel profile, painted or completely galvanised (also optionally painted upon request) or optionally made of stainless steel.


Easy installation:

The EBW 20-SC can be installed quickly and easily. Weighing frame and load carrier are delivered fully assembled. The scales’ support spars are easily screwed upon the conveyer. By exchanging the spars, the scale can quickly be adjusted to another belt width.


Low maintenance:

The robust construction of the belt scale requires low maintenance. It works reliably for years, as long as no external disturbance occurs (lightning strike, overload, etc.).

 

We recommend to comply with the measuring accuracy:

  • daily zeroing
  • regular external checking
  • annual adjustment with reference material or with test weights

 

MID approval:

The belt scale has in conjunction with the control unit WC 9604

  • a certificate of type examination (MID approval)

as an automatic scale for totalizing - belt scale based on OIML R50 (DIN 8132).

Functioning

The continual flow of materials on the conveyer results in a pressure load upon the weighing platform of the belt scale, which is recorded by the strain gauge load cell. At the same time, the measuring wheel running simultaneously on the lower belt and records the current belt speed.


The weight value of the material on the measuring station and the speed value of the conveyer belt combine to give the overall flow rate in tons per hour.
