and improving productivity. Effective and
precise process control can have a major
influence on manufacturing efficiency but
in the past this could provide a significant
challenge to those with pneumatic
conveying systems.
One recent innovation from Bürkert uses
a closed loop controller, pressure sensors
and a control valve, all combined into
a single unit. The Type 8750 flow rate
controller provides an automated air flow
control solution that can reduce operating
costs and improve productivity through
better flow control and management of
the compressors.
The flow rate control system is supplied
as a complete assembly that negates the
requirement for a separate flow meter.
Using the pressure difference across
the valve and the given density and
temperature of the medium, a nominal
flow can be calculated, providing the flow
characteristics of the valve to the process
controller.
One example of this system delivering
benefits to a production process involved
a company that manufactures tyres and
uses carbon black, a fine powder, as part
of the process. The powder is conveyed
from a storage tank to a mixer using a
dense phase pneumatic system.
The tyre manufacturer selected the
Type 8750 flow control because it is
able to maintain a consistent dense
phase transport method, while
using compressor energy efficiently.
Furthermore, when the pipes needed
to be emptied, a very high flow rate was
required and the Type 8750 was also able
to achieve this.
Due to the compact nature of the Bürkert
flow rate controller it is simple to install in-
line and can be easily integrated into the
existing process control infrastructure.
A video has been produced which
features Thomas Sattler, Team Coach
Application Management Gas, a product
expert describing how the Type 8750
offers end-users a cost effective solution
that will minimise damage to the process
materials and increase productivity
by providing better flow control
and management of the pneumatic
compressors.
It also highlights how it improves the
energy efficiency of the manufacturing
process and helps system integrators
to provide an effective solution that is
straightforward to install and reliably
delivers reduced operating and
maintenance costs.
