Bulk Solids PumpTM for precise feeding of free flowing bulk materials in a process

First in the Industry: Positive Displacement Feeding Technology

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

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

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



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



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



Zone 3: RELAXATION
Interparticle forces fall below lock-up threshold



Zone 4: ACTIVE DISCHARGE
Material discharge occurs.

The Anatomy of the BSP-100 and BSP-135

The Anatomy of the BSP-150-S and BSP-150-P

Four Base Models Cover a Wide Range of Needs

BSP-100
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.

BSP-135
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
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. 

BSP-150-P
The BSP-150-P is a 5-duct version based on the same technology as the BSP-100, but manufactured of carbon fiber reinforced plastic. It also includes an inlet transition piece, a low power DC motor and a removable stainless stell material discharge chute.

The BSP-150-P is designed for feed rates of 46 to 9,000 dm³/hr (1.6 to 318 ft³/hr) and 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
