Designed for batch and continuous applications where volumetric feeders serve best

Volumetric feeders offer a low cost and easy to use option for batch or continuous applications where the bulk density of the material being fed is consistent or when precise feed accuracy is not critical to the quality of the end product.

For greater feed accuracy, volumetric screw feeders are frequently employed in gain-in-weight batching applications. When process requirements are more demanding, screw feeders with gravimetric scales and loss-in-weight controls provide a higher level of accuracy.

At Colormax Systems, we make volumetric screw feeders that provide reliable and consistent performance. Single screw volumetric feeders are the best choice for easy flowing materials, while twin screw volumetric feeders are the best solution for bulk materials which are more difficult to handle. Volumetric feeders are available in a variety of models and hopper sizes to meet a wide range of feed rates.

Twin Screw Volumetric Feeders

Colormax Systems Twin Screw Volumetric Feeders are designed to provide accurate volumetric feeding for a wide variety of difficult materials including poor flowing powders, fibers and flakes.

All material contact parts are stainless steel. The feeder is easily disassembled for cleaning or change over. The special design of the feeding bowl is patented and employs a unique horizontal agitator to improve material fill of the screw flights. The feeding bowl design allows material to flow evenly from all directions into the screw and effectively avoids material build-up, making feeding more accurate. An optional vertical agitator is available for poor flowing powders that tend toward bridging.

Optimum feeder screws are determined based on the material characteristics. The following estimated feed rates are for free flowing materials. For feed rates at either end of the range, feeder testing is recommended.
