|Asphalt plant fire box automatic cleaning system
The fire box was constantly blocking during production due to the addition of recycled asphalt product (RAP) and other back-fed materials. Operators were required to get inside the mixer and jack hammer the fire box clear every other night to prevent plant breakdowns. This process involved working in a confined space, regular exposure to risks from HAVs, dust and working in a hot environment.
To resolve this issue, a small vibrator was installed at the back of each fire box. The vibrators are connected to the control system; they operate every time a swivel chute discharges. This prevents materials from sticking and building up in the fire box.
• The fitters no longer have to enter a confined, hot and dusty environment
• The usage hours of vibrating tools has been reduced considerably
• More efficient production and improved team engagement
