Proven technology + state-of-the-art design = the ultimate solution for feeding solid fuels
For more than six decades, Schenck Process weighfeeders have been paradigms of reliability, precision and operational safety. While these long-established products have enjoyed a glorious history, their quality, functional, software and stability features have now been further refined.
The Stock Equipment Company* has been part of the Schenck Process Group since 2006. This company has long been a leader in shock pressure-proof systems. The MULTIDOS® High Pressure Gravimetric (HPG) weighfeeder is the result of collaborative work between the two companies. It is a new generation of weighfeeders/coal conveyors resistant to 3.5 bar shock pressure, offering greater efficiency than ever before.
The first choice for fuel feeding
The gravimetric feeding technologies constructed by Schenck Process for coal feeding since the 1930s are considered highly reliable and as the standard for accurate raw coal weighing and feeding; something proven by the fact that more than 9000 are installed worldwide.
Using state-of-the-art design elements, this proven technology has now become the ultimate solution for feeding solid fuels. It is called MULTIDOS® High Pressure Gravimetric or MULTIDOS® HPG for short.
New design elements deliver greater efficiency
State-of-the-art mechanics and new design elements with enhanced software technology and extended control functions have been added to the MULTIDOS® HPG weighfeeder.
For example, the MULTIDOS® HPG’s tension roll and active belt steering system maintain belt alignment. The belt is also centred in the event of an uneven distribution of load. This removes the need for a V-guide and extends the belt’s service life. An internal belt scraper has been incorporated to extend the life of the drive components. And the drives can now be fitted on the left or right in the field.
An inlet (610 mm, 914 mm or 1000 mm wide) ensures an even flow from the coal bunker, even with coal grades with awkward material flow properties.
Structural explosion protection is enhanced by sloped or rounded internal surfaces and prevents coal build-up on the inside of the weighfeeder, ensuring safe operation in dust explosion zones.
Even the technology and software details are impressive. The MULTIDOS® HPG features DISOCONT® Tersus feeder electronics with enhanced software technology and extended functions for optimum control of gravimetric feeders using a graphic touch screen interface.
The final element of the MULTIDOS® HPG design concept is that is designed in line with NEC, CE and ATEX requirements to offer state-of-the-art safety.
