Specifications
thermal equipment rotating calcining kiln1.calcine and dry
2.can be divided into metallurgy kiln, limestone rotary kiln, etc
As the main equipment in both of the cement clinker dry and wet process production lines, this cement rotary kiln is widely used in metallurgy field, chemical industry, building refractory material sector, environmental protection field, and so on. It mainly consists of cylinder body, supporting device, supporting device with catch wheel, driving device, movable kiln head, sealing equipment of the kiln end, coal spraying pipe, etc.
The cement industry in the process of the development of production method appeared different and different types of rotary kiln, according to the method of preparation of raw material can be divided into dry process production and wet production, and the production method to adapt the rotary kiln is divided into dry process rotary kiln and wet hair two kinds of rotary kiln. Due to the end of the plume heat different devices, and can be divided into different types of kiln.
The rotary kiln, rotary kiln working principle by the barrel, transmission device, ask, block wheel support device, kiln head, sealing, kiln hood and burning device components, kiln cylinder is heated rotary parts, using quality calm steel plate welding is made, the cylinder body through the LunDai supporting in 2 ~ 7 sliding block or rolling bearing of supporting device, and in which a block or a few block supporting device with the machine or hydraulic block wheel, to control the barrel of the axial channeling move; Transmission device through the barrel of the tooth to central circle cylinder body according to the requirements of the speed turned; Due to the need of installation and maintenance, the bigger the kiln has made the cylinder body with a low speed rotary auxiliary transmission device; To prevent cold air into the flue gas and dust overflow cylinder, in the cylinder of the incoming (tail) and the material end (head) a reliable preheater and kiln head seal device. Cylinder Settings on test and sampling hole device, kiln hood on pressure measuring element with larger specifications of kiln can also set the h_2s infrared to the cylinder body monitoring temperature measurement.
[The rotary kiln classification ] Cement rotary kiln Cement kiln at present basically has two kinds big, one kind is a kiln cylinder lie for slightly rake), and can be turn movement called the rotary kiln (also called XuanYao); Another type of kiln cylinder is made for not rotating called shaft kiln.
1. wet of rotary kiln type:
Used for the production of the wet cement kiln says wet kiln, wet production is made of raw water will is 32% ~ 40% of the pulp. Due to the preparation of the liquidity into a mud, so the raw material mix between, raw material components uniform, make the firing of clinker high quality, and this is the main advantages of wet production.
2. and dry process of rotary kiln type:
Dry process rotary kiln and wet kiln and their advantages and disadvantages compared with just the opposite. Dry process will be made dry raw raw, moisture generally less than 1%, so it BiShi method to reduce the evaporation of water energy. Hollow type kiln because the flue gases to the high temperature, so the heat consumption not low. Dry process production of raw material will be made dry powder, its liquidity than poor mud. So raw material mixed bad, non-uniform composition. Cement rotary kiln
Mainly used for calcining cement clinker, points dry process production cement rotary kiln and the wet cement rotary kiln production two kinds big. Metallurgy chemical rotary kiln is mainly used in metallurgical steel iron ore poor magnetized roasting; Chromium and nickel iron ore oxidizing roasting; Refractory plant high aluminium vanadium and soil ore pellets roasting, iron, aluminum hydroxide and aluminum; Chemical plant GeKuangSha and chromium such as ore pellets of minerals. Lime rotary kiln (i.e. active lime rotary kiln) used for roasting steel mills, the activity of ferroalloy factory with lime and the light burning dolomite.
