Feeders
Tomal’s multi-screw volumetric feeders unique design uses multiple, overlapping, counter-rotating screws that effectively create a “live bottom” in the storage bin and eliminate the need for bin activators, rotary valves and intermediate hoppers.
A comprehensive range, constructed in either mild or stainless steel and with single or dual outlets guarantees a TOMAL® design solution is available for any volumetric or gravimetric application.
Specialist designs enable Tomal's benefits to be applied to hard to manage products or industry specific requirements. An example is the Tomal 305EC which may be easily dismantled without any tools to meet the easy-to-clean needs of the food and chemicals industries
The multi-screw design ensures a reliable bin discharge with an inherent resistance to arch building. The highly reproducible “discharge per rotation” means that metering accuracies of 0.5% - 1.0% are easily achieved, costly overdosing is minimised and precise formulation is guaranteed.
TOMAL® metering systems are well proven across a broad range of industries including: water & waste water treatment, mining, chemical, pulp and paper, food, glass and porcelain, building materials and environmental control.
The TOMAL® Volumetric Feeder Advantages:
-
safe, reliable, self-cleaning discharge with high resistance to arch building;
-
robust and low-wear construction suitable for continuous or batch processes;high metering accuracy, better than +2%, with linear discharge curves;
-
a wide range of models in mild or stainless steel construction
-
a complementary range of slide gate valves for isolation.
