Mid-sized briquetter is improved
The B-220 Series pilot plant and small production volume briquetter from KR Komarek has been redesigned to simplify maintenance, facilitate roll changes and strengthen the drive train
Cantilevered design - in which rolls are mounted outside of, rather than symmetrically between, their bearings -- simplifies roll changes, ensuring easier installation, operation and maintenance, and permitting users to quickly adapt the unit to different products.
Compared with symmetrical rolls, cantilevered rolls stay more nearly parallel as they are displaced by material passing through them, resulting in greater control of briquette volume uniformity.
Vertical pairing of the rolls permits horizontal in-feed for more uniform mass flow rates to the rolls, plus greater control in feeding finely divided materials to the rolls, making this design especially well suited for briquetting or compacting powders and reclaimed dusts.
Dust-tight roll enclosures are available where needed.
In operation, the briquetting rolls rotate in opposite directions so their adjacent surfaces meet each other moving in the same direction as particulate materials are fed between them from one side.
Cavities in both roll surfaces then close around these materials, compacting them under forces up to 125 tons.
Roll shafts of KR Komarek briquetters are individually driven directly from the output shafts of a specially designed dual-output gear reducer.
This technique couples the roll shafts together with greater torsional rigidity compared to drive trains that power one roll shaft from a conventional gear reducer then drive the second roll shaft from the first via companion gears.
Briquetting rolls are offered in a variety of special abrasion and corrosion resistant alloys to suit the materials being compacted.
All machines can be equipped with specially designed transducers to monitor briquetting pressure, roll drive torque, roll separating force and feeder torque.
