High Temperature Application
The Solution
For application in the high temperature range, AGRICHEMA’s SHOCK-BLOWER® air-blast units are equipped with specific heat-resistant nozzles to remove cakings of material.
The Concept
Size and number of the SHOCK-BLOWER® air-blast units and the exhaust system tobe applied are determined by:
- the bulk material's characteristics,
- local factors,
- type and form of material cakings
This diagrammatic view shows possible places of application of AGRICHEMA's SHOCK-BLOWER® for automatic removal of unwanted cakings of material in a preheater system for rotary kilns used for cement production.
The Design
Execution
Valve Units DN 100 and DN 150.SHOCK-BLOWER® from AGRICHEMA consist of a storage tank for compressed air or inert gases and a valve unit with control unit.
The storage tanks are made according to EURO standards and are hot galvanised on the inside and outside.
The valve unit with its vent seat made of Cr-Ni-steel is protected and arranged within the storage tank, even so it can be easily maintained and controlled from the outside.
The control unit “SIKOBETIC®” from AGRICHEMA guarantees a reliable operation of air blast units (even during fluctuations in the compressed air network). Additionally the “SIKOBETIC®” offers a simple handling and maximum security for the operating staff.

Execution Valve Units DN 40 and DN 65.
The air blast forces have been tested at the Chair of Mechanical Process Engineering of the University of Kaiserslautern with state-of-the-art methods. The corresponding study can be obtained as special print from AGRICHEMA (English version).
Accessories
SIWARTIC®
AGRICHEMA's SIWARTIC® with filter regulator and 3/2-way ball valve, lockable threefold, is used as a safety
maintenance unit for reliable forced venting of the SHOCK-BLOWER® units.
Automatic Cycle Controls (ATS)
The automatic cycle control for SHOCK-BLOWER® (ATS) is freely programmable.
Thus, all bulk material disruptions can be eliminated by individual control of the SHOCK-BLOWER® units.
SHOCK Control (SCS)
The SHOCK Control is monitoring the SHOCK-BLOWER®'s function.
Option: Pressure sensor/pressure transmitter for monitoring the operating air pressure.
Further Accessories:
Air pipes, sets of fittings and installation accessories.
The Nozzle System
AGRICHEMA’s multifunctional heat-resistant nozzles provide customized solutions.
Type 0° exhaust angle Heat-resistant nozzles in refractory brick lining
0°, 20° and 90° exhaust angle
Type 0° exhaust angleHeat-resistant nozzles in changing tube
0°, 20° and 90° exhaust angle
- Longer service life of the heat- resistant nozzles (1) through passive and active air cooling in changing tube (2).
- Easy replacement without flame-cutting and welding.
Heat-resistant nozzle with refractory nozzle brick 0° exhaust angle
- Long service life under extreme working conditions through refractory nozzle brick (1) with support box (2).
- Quick inspection from outside by easy dismantling of the front plate (3) with heat-resistant nozzle (4) is possible.
