Coperion K-Tron at Fakuma 2014

Coperion K-Tron cordially invites you to attend Fakuma 2014, Oct 14-18, 2014 in Friedrichshafen, Germany, Booth 6406, Hall A6 to learn more about the latest advances in feeding, weighing and pneumatic conveying solutions.

We will show you the patented BSP-135 Bulk Solids PumpTM Feeder on pivoting base frame which has been specially designed and engineered to provide gentle, precise feeding of free-flowing pellets, granules, and friable bulk materials.

Additionally on display will be a Gravimetric Batch Blender with integrated 2400 Series Vacuum Receivers and a Twin Screw Powder Feeder.

Stop by the booth and explore our innovative solutions.

We look forward to seeing you at Fakuma 2014!

Bulk Solids PumpTM for precise feeding of free flowing bulk materials

First in the Industry: Positive Displacement Feeding Technology


The new Coperion K-Tron Bulk Solids Pump (BSP) feeders have been specifically designed and engineered to provide gentle, precise feeding of free-flowing materials

The Features

Coperion K-Tron Bulk Solids Pump (BSP) feeders have been specifically designed and engineered to provide gentle, precise feeding of free-flowing pellets, granules, and friable products.

Preview animations and video

The BSP feeders do not use the usual screws/augers, belts or vibratory trays to convey the material. The feeder utilizes positive displacement action to feed free flowing materials with astounding accuracy, offering uniform discharge, consistent volume and gentle handling.

The BSP feeders have vertical rotating discs that create a product lock-up zone, conveying the material smoothly from storage hopper to discharge outlet, achieving true linear mass flow.

Utilizing a simple design and the principle known as “lock up” (see demonstration), the material in the feeder is moved together in true positive displacement, producing excellent linearity and breakthrough accuracy levels.

With no pockets or screws and only one moving part, the compact feeder is cleaned in seconds, making it ideal for applications with frequent material changes.

The Principle

Interparticle forces produce lock-up at the end of Zone 1


Material is in lock-up condition throughout Zone 2 and rotates as a solid body


Interparticle forces fall below lock-up threshold


Material discharge occurs.

The Anatomy of the BSP-100 and BSP-135

exploded view of BSP-100 and BSP-135



The BSP-100 features a single feeding duct formed by two rotating discs. It includes a conical inlet transition piece which can be combined with a variety of standard extension hoppers.

A slide gate on the inlet allows for material shut-off and removal of feeder for cleaning and hopper emptying. A low power stepper motor drive mechanism and controller provide excellent turndown and flexibility ensuring a very wide operating range.


The BSP-100 is designed for feed rates of 2 to 400 dm³/hr (0.07 to 14 ft³/hr). It is available as a volumetric unit or as a gravimetric unit with a choice of 2 platform scales, single point suspension scale or three-point suspension scale.



The BSP-135 is a slightly larger version of the BSP-100, with all the same features except that it has three feeding ducts instead of one.

The BSP-135 is designed for feed rates of 22 to 4,400 dm³/hr (0.8 to 155  ft³/hr).

Unit is available as volumetric or as gravimetric, with a choice of platform scale, single-point suspension scale, or three-point suspension scale.



BSP-150-S is designed with four feeding ducts, and is based on the same technology as the BSP-100, but manufactured of stainless steel.

The unit is designed with an inlet transisiotn piece, as well as a stepper motor and removable material discharge chute.

With only one moving part and no pockets or screws, the design provides ease of use and almost zero maintenance.

The BSP-150-S is designed for feed rates of 34 to 6,700 dm³/hr (1.2 to 237 ft³/hr).

It is available as a volumetric unit or as a gravimetric unit with a three-point suspension scale.



Benefits of the Revolutionary BSP Technology

  • True Positive Displacement Action
  • Linear Over Full Operating Range
  • Uniformity of Discharge
  • Active Discharge (minimal residual material)
  • Unaffected by Differential Pressures
  • Mechanical & Maintenance Simplicity

Gravimetric Batch Blenders

Coperion K-Tron Gravimetric Batch Blenders are available in various sizes from 0.5 kg to 25 kg total batch size and include up to 8 main feed elements depending on the unit.


Each one of the materials is dispensed sequentially into a common weighing hopper in the desired proportions. The weighed materials are then released into a separate mixing chamber, which provides a consistent homogeneous blend. It includes an advanced metering and weighing system that accurately controls every ingredient of every batch to the desired amounts and is not averaged over multiple batches.

Gravimetric Batch Blenders Design Features

The Coperion K-Tron range of blenders are compact with a robust design. They are designed and constructed of heavy gauge steel (11 gauge steel) to withstand the most rigorous of operating conditions. The load cell is overload protected and guarded from physical damage. Each blender is constructed with high load bearing continuous welding and is protected against vibration and shocks. All blenders include self-optimizing software to give you the most efficient output on every recipe. Continuous mixing of the bulk materials means the mixing times do not need to be adjusted and the consistency of every mix is guaranteed.

Standard Mechanical Specifications

  • Ingredient accuracy of +/- 0.02% per batch at highest accuracy setting
  • Robust design (11 gauge steel)
  • Color touch screen
  • 3 level password security
