Product Details



This machine adopts the PLC programmable controller as the core control part. The performance is


stable and reliable. With touch screen and friendly screen, you can control, set, display test time (A. Dust


time: blowing, stopping, blowing), B. Preset test time can be controlled, etc.). Effectively guarantee the test


according to standard operation.


Programmable controllers individually or collectively control the blower fan, dust vibration and total test


time, No fuse protection switch, over temperature, overload protection, etc.

Dust system

Blowing dust fanDomestic brand-name high-power vortex fan
Blowing dustThe upper part of the chamber is equipped with sand dust outlet. The sand and dust in the dust funnel are blown into the laboratory through the dust blower to carry out sand and dust test.
Sample housing evacuatedEquipped with a vacuum pump for evacuating the sample housing
Dust collectionThe inner box adopts a conical bottom which gathers in the vicinity of the blow hole of the inner box when the dust falls, and equipped with a periodic vibrator, dust outlet, shut down to remove dust.
System Configuration


Equipped with a pressure gauge, vacuum pump, air filtration, pressure regulator triple pieces, connecting pipe

Dust filtrationPrecision dust filters, filter bag. Balance the pressure inside and outside the box

Dust drying system

Temperature control equipmentHeating ring, before the nozzle of dust
Control methodHeater control: non-contact cycle pulse width modulation, SSR (solid state relay)

Control Panel

Siemens true color touch screen + Siemens PLC control

Remote control system (optional)

Controller remote control software is available. The customer installs by themself. (RS485 interface must be on the computer, the company can provide the RS485 interface, PCI card) or provide the computer installation and commissioning by the company. (Optional)
