|Volumetric feeders can provide reliable feedrates with accuracies to ± 1 % by volume, or ± 3% by weight. Volumetric feeders meter a consistent volume of material, such as a screw pocket, by the speed or revolution rate of the discharge device. This releases a steady quantity of material over time, which provides an economical way to meter materials that have a consistent bulk density.|
In business since 1908, MERRICK offers the exceptional design and quality components that reflect our long-standing commitment to excellence in the design and manufacturing of volumetric feeders and many other material handling solutions. We understand that our clients depend on their feeders to deliver consistent, repeatable results, and each of our volumetric feeders is designed with reliability and the highest level of performance in mind.
At MERRICK, we feature three different types of volumetric screw feeders, which are designed to deliver material at varying rates:
- Series 25 (0.03 ft³/hr to 95.00 ft³/hr)
- Series 50 Dual Transverse (0.03 ft³/hr to 72.00 ft³/hr)
- Series 100 (0.003 ft³/hr to 900.00 ft³/hr)
Also, any of our weigh belt feeders can be designed without the integrated scale to be used as a volumetric belt feeder.
Volumetric feeders are utilized industry-wide to reliably dose materials without an integrated scale device. For many applications that require repeatable accuracy within ± 0.25%, a gravimetric feeder may be recommended. Gravimetric feeders feature a highly accurate scale which monitors the feeding process by weight and adjusts the feed rate to ensure the proper amount of material is delivered at all times.
To help you select the volumetric feeders that will best serve you and your company, take advantage of the exceptional customer service provided by MERRICK. Whether you need gravimetric feeders, volumetric feeders, weigh belt feeders, conveyor belt scales, or a loss-in-weight feeder, we’re happy to answer your questions and demonstrate how our designs can handle and meter your specific material.
