WEIGH SCALE BLENDER
Overview
L-R Systems “WSB” series weigh scale blenders are designed to mix from 2 to 6 components according to
one of 99 recipes loaded in the memory. Materials are individually metered by vibratory feeders into the
batch weigh hopper until a recipe-based set point is reached. Weigh hoppers range in size from 25 to 250 lbs
capacity depending on the size of your blender. To permit increased accuracy, vibratory feeders have “slow
feed” set points adjustable from .3 lbs to 5.0 lbs before the final component weight set point is achieved.
After the batch is completed, the weigh hopper automatically dumps into our “First-in, First-out” mixing
barrel. This “dump time” is adjustable from 0 to 20 seconds. When a batch is dumped into the mixer a mixer
timer, which can be set between 0 and 60 seconds, starts timing. After the set mixing time this timer allows
your vacuum loading system to unload the mixed material from the mixing barrel or, as an option, opens the
slide gate to dump the mixing barrel into a collection box. (Contacts 103, 104)
The control panel features a Color touch screen with an easy to use Graphical User Interface (GUI), which
shows recipe entries, run status and alarm messages. The control panel also continuously totals the weight of
each component and stores this information for future retrieval. Information of totals and recipes can be
printed via RS232 serial communication port.
L-R Systems blenders have always been built rugged to last. Our standard for ample surge capacity,
thorough mixing, and outstanding performance makes L-R Blenders your best buy.
L-R blenders perform at or better than 0.02 lbs accuracy per component per batch.
