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

SPECIFICATIONS

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.

What to Expect from Lancaster Products High Shear Mixer Sample Testing

Our last post focused on our experience in concept testing and how it applies to our high shear mixer sample testing process. This post will dig in a little deeper and provide insight into the breadth of data we provide to our customers when they commission Lancaster Products to provide sample testing for them.

Over the past 30 years, we have collaborated with our customers to perform proof of concept testing in our K1 laboratory mixers for thousands of materials samples. The desired outcome of the testing is customer dependent but typical requirements are along the lines of pelletizing/granulating to specific size ranges and desired yields, mixing to achieve homogenization, or reduced reaction times of existing processes. Outcomes provided are 1) proof of concept in achieving the desired product, and/or 2) optimization of the current mix processes. Our engineers perform the tests in our controlled laboratory, log all key information in our database, and share all data with our customers for future reference. Below is a list that summarizes some of the information we collect during every test run we perform:
