Cement Industry

Monitor and control cement production - from the raw material conveyance to the crusher; from mixing bed and dosing station to the raw material mill. Look into the rotary kiln and see the burner zone; monitoring the clinker distribution into the clinker cooler: PIEPER's CCTV camera systems will show you all major stages of production. Digital process technology offers many automation; UV-sensitive CCD cameras allow for flames to be precisely assessed and controlled.

  • For more than 30 years, PIEPER GMBH have been dedicating their activities to that special furnace technology and design, develop and manufacture such high-temperature equipment.
  • For more than 30 years, international cement manufacturers have relied on our high-tech camera systems used in cement production - worldwide!


Rotary kiln

In the rotary kiln, the sintering zone is monitored using water-cooled furnace CCTV systemes; the systems are suitable for temperatures of up to 2400°C. They are provided with fully automatic retraction devices and allow for processes in the sintering zone to be visually monitored and controlled. Colour cameras may be used to observe and evaluate the condition of clinker. Also, the colour pictures allow for flame patterns to be assessed, thus substantially improving control arnd adjustment the burners. For special observations inside the furnace, the camera sensitivity in the UV spectrum is of great importance, e.g. for burner adjustment (see above).

When installed on cement rotary furnaces, furnace probes equipped with axial sightholes are used, with the horizontal and vertical angle of image being defined by selecting among a number of various furnace lenses.

Clinker cooler

Clinker distribution on the cooling gratings is monitored by water-cooled CCTV systems as well, the furnace probe, however, being provided with a radial sighthole which may be made alternatively with an angle of 70° or 90°; the angle of view is 58° (H) x 45° (V) or 81° (H) x 65° (V).

All video images are transmitted to TV monitors in the central control station where any required adjustment and correction is performed. Additional functions in the furnace probes allow for the inside temperature to be visually displayed (option): also, data from other sensors can be mixed into monitor picture.
