Working Principle And Emerge Treating Of Rotary Kiln

Working principle:

Working principle:

, the raw material layer surface and the horizontal angle is equal to the angle of repose, of raw materials, the raw material particles under the action of gravity, slide down along the material layer. A certain inclination of the rotary kiln (rotary kiln), the raw material particles rolling along the maximum direction of the gradient decreased, and moved forward a certain distance.When the material in the kiln movement, the movement of raw material particles cyclical changes, or buried in the material layer inside the kiln with the upward movement, or to the material layer on the surface and landed down. But only in the raw material particles along the surface layer of the landing process, it can move forward along the direction of the kiln length. Raw material movement in the kiln will affect the residence time of raw material in the kiln (ie, raw material heating time); fill factor (ie, the raw material in the kiln raw materials heated area); raw material granularity flip, but also affect the uniformity of the raw materials (ie, affects the surface temperature of the combustion products and raw materials).

In a rotary kiln operation process, there will be a variety of situations, the following is the processing of the rotary kiln prone to coke bricks situation.

Rotary kiln a rotary kiln furnace coke bricks, you can take the following actions to deal with:

Focusing on prevention, closely monitor the fire preheating zone, preheating zone fire development to fire the trend, it is necessary to advance from the warm-up with the rear to extract high-temperature gases. When well done the obvious omen, can be firing with waste heat gate lift, set fire to cool down in advance. Control the speed of the fire line.Regardless of whether the waste heat utilization system, reducing the height of each damper delay attempting to road speed, are beneficial to control the fire degree. When firing to bring well done, to the waste heat of the fire at the before and after gate mention a few to spread the fire. If waste heat on to mention the fire at the gate, not only can not scattered fire, so they will fire focus, excessive burning. When firing with bottom well done, first to drop the low far gate and near gates, to mention a waste heat gates, but also increase the amount of wind, accelerated cooling. In addition, it is also prudent to gradually lift the insulation with the Kazakh damper, the air out of the bottom of the high temperature. But be careful, not to mention the fire at the Ha damper, not only because it can not be scattered fire, and instead concentrated firepower, there will be the focus brick, even knot lump or down the kiln the accident.

With its high quality products such as Impact stone crusher, Raymond mill, China impact crusher, Dryer machine, Rotary kiln, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
