The dry and wet types dry and wet types rotary kiln is not only important equipment in cement making production line, but also the heart of cement enterprise. We must use and maintenance for dry and wet types rotary kiln, and ensure the normal and the long-term safety operation. In view of equipment management, the straightness of dry and wet types rotary kiln centerline and the inclined Angleall of each axis are particularly important. With the rapid development of dry process rotary kiln technology, equipment management personnel of many cement enterprise still have relatively weak consciousness in this field. They know a little advantages and disadvantages about relationship between centerline straightness of the dry and wet types rotary kiln and wheel axis's inclined Angle, and the right orientation of wheel axis and the long-term safety running, they often adjust excessively wheel to make the centerline of dry process rotary kiln and inclined Angle of wheel axis disorder, and even cause all kinds of accidents to happen unnecessary financial losses.
The wet process rotary kiln is mainly used in metallurgy, building materials, ore and so on for many kinds of mineral material heating and burning. Such as ceramic sand, bauxite, limestone, cement metal magnesium, alumina, and hydroxide aluminum, refractory and so on. The centerline of the wet process rotary kiln should be in a good linearity state in hot state, but the center line of dry and wet types rotary kiln in the cold should be in what state, the concept and the processing method on this problem are different at home and abroad, but they are reasonable each other, we should use for reference.
The technical characteristics of dry and wet types rotary kiln:
(1) The kiln body using the high quality carbon steel or alloy steel plate calm and automatic welding;
(2) Tyre, holds wheel, open-typed gear adopting the alloy cast steel;
(3) Sliding bearing with large clearance bearing;
(4) The transmission device adopts reducer of hard tooth, elastic diaphragm coupling, dc motor;
(5) Adopting hydraulic block wheel;
(6) Kiln head using the scale pressure and kiln end adopting cylinder seal tightly;
(7) Adopting a slow dri.
