Lancaster Products Rotary Table Feeders convert intermittent batch processes into a continuous material feeding process.
A Lancaster Products Rotary Table Feeder is an important part of industrial material processing equipment line. Industrial table feeders are used when the moving and feeding of powder or granular substances is necessary. Lancaster Products Rotary Table Feeders benefits include:
- Variable flow rates
- Use with difficult flowing materials
- Gentle handling of green or weak materials
- Prevents material bridging
- Convert batch processes into continuous process
- Available in a variety of table diameters and storage volumes
Lancaster Products Rotary Table Feeders come in three standard sizes:
- 30 inch diameter
- 42 inch diameter
- 60 inch diameter
The storage volume is dependent on storage needs and flow rate (lbs/hour or tons/hour). When coupled with a Lancaster Mixer, table feeders are typically designed to hold 1.5 mixer batches while operating. The table feeder can also be designed for several discharges to feed multiple production lines simultaneously.
Lancaster Products Rotary Table Feeders are available in Stainless or Carbon steel versions.
VARIABLE FLOW RATES
Our feeders’ variable flow rates can provide even flow of material from the table feeder to your downstream processing equipment. The flow rate is adjusted by changes in the angle of the discharge plate and table rotation speed – turning an intermittent process into a continuous flow process.
The amount of material leaving the table feeder can be controlled by changing the angle of the discharge plow either manually or automatically. The feed rate can also be controlled by using a variable speed table drive motor to adjust the speed of the bottom rotating table.
USED WITH DIFFICULT FLOWING MATERIALS
Lancaster Rotary Table Feeders are particularly helpful in moving sticky or hard to feed materials. Powders, fibers, flakes, and pellets are all handled easily and efficiently. The feeders gently transport delicate materials such as green pellets that could be damaged by other material transport methods. The rotary action of the feeders prevents bridging of hard to feed materials. We often close couple table feeders with our Lancaster High Shear Counter-Current Mixers to change the batch processing of mixer to a continuous process.
BATCH TO CONTINUOUS PROCESSES
The table feeder can also convert a batching process into a continuous process. The cone and cylinder over the table is then used as a surge hopper to temporarily store the material batch while the table feeder continuously discharges the material.
BIN DISCHARGING APPLICATIONS
For bin discharging applications, the industrial table feeder attaches directly to the bin walls forming the bottom of the bin. Some of the most difficult flowing materials can then be evenly fed from the bin. The entire assembly can be known as a live-bottom bin.
HOW IT WORKS
The Lancaster Rotary Table Feeder consists primarily of a transition cone, a rotating table, a discharge plow, a drive mechanism, and a support structure. The table feeder uses a large flat rotating table to continually bring material from the cone to the discharge plow. The table has vertical pins attached inside the cone area.
There is also a cone scraper blade attached to the table. As the table turns, the blade and pins agitate the material and keep it evenly flowing to the discharge plow. An adjustable seal band rides on the outer surface of the table to prevent material from exiting the table feeder outside the discharge area. The discharge plow is used to bring the material to a fixed point as it leaves the table.
The rotating pins and the inner rotating plow provide a constant feed of even the most difficult materials.
CUSTOM TABLE DIAMETERS
The table diameters range from 24 in to 6 feet. For larger dimensions, please Contact Lancaster Products.

Lancaster Products High Shear Counter-Current Mixers are highly effective in their ability to mix and pelletize in one machine and one process, but Lancaster Mixers are also built to last. Many of our machines are still operating after decades of use. We continue to supply parts to many vintage year machines still in operation.
Lancaster Products machines are built with a robust construction that provides structural durability and are designed to allow for replacement of wear parts as needed to extend the operational life of our machines instead of total machine replacement. To our customers this translates to lower Total Cost of Ownership and higher return on investment than other mixers. With proper maintenance, Lancaster Products mixers are very long-lived machines.read more
Lancaster Products is dedicated to process and mix design optimization. Whether you are looking to develop a new process/product or improve on an existing process, Lancaster Products can help. From mixing to granulating or pelletizing, our experienced application engineers can design toward many objectives, including: mixing cycle times, binder and minors optimization, homogeneity, particle hardness, moisture and air entrainment, particle size distributions and yields.read more
