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.

This is the third video in our lab and testing series. The Lancaster Products Lab is equipped with a production-sized K4 mixer to test and optimize mix recipes at full scale. In this video, we are testing a clay type of material for pelletization.
The K4 mixer introduces a third tool, the low-speed plow, which, along with the rotating pan, transports material to the high-speed rotor. You can see how the high shear counter-current movement creates a rolling action which agglomerates the materials into pellets. The K4 mixer has a bottom discharge; the plow allows for the rapid and complete evacuation of the mixing cavity. After the mixer is fully evacuated, the bottom discharge closes, and reseals ready for the next batch.
This is the second video in our lab and testing series. The Lancaster Products lab is equipped with a small production-sized K3 mixer to test and optimize mix recipes at a prototyping scale. In this video, we are testing a clay type of material for pelletization.
Looking inside of the mixing cavity, you see the counter-current mixing action. The pan rotates clockwise, and the high shear mixing tool spins counterclockwise. The mixing pan actively transports material to the primary mixing tool. Slowing the action down gives us a good view of how the Lancaster mixing action creates a tumbling that promotes agglomeration by rolling the particles much the same way as a snowball growing larger by rolling down a hill.
