2. SPECIFICATIONS. 3. STRUCTURE. Multifuel burner is a new combustion device burning gas and coal powder in rotary kiln. It has a unique structure and reasonable parameters to ensure gas, coal powder and air, primary air and secondary air mixed sufficiently. It brings greater thermal intensity, higher combustion efficiency and easier adjustment.
The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level
I NHSB super burner The burning of coal is very complicated. The composition and reaction features are different. Different kinds of coal, different process and different types of kiln will have different requirements to burners, esp. low quality coal (high-ash coal, anthracite etc.), whose higher burning efficiency working region is narrow, the allowance for adjusting burner is small.
Working Principle of Cement Mill: The cylinder will rotate by the transmission device. Due to the inertial centrifugal force, the steel balls will stick on the liner plate and rotate with the cylinder together. When the steel balls come to a certain height, it will fall down by gravity and impact the raw material.
