Product Description

Wet process cement rotary kiln for calcined dolomite in cement industry



Production introduction:
The rotary kiln refers to the rotation calcining kiln (known as rotary kiln), belonging to the building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials. The Cement kiln is mainly used for calcining cement clinker, including dry and wet-producing cement kiln. The metallurgy chemical kiln is mainly used for lean iron ore magnetized roasting in steel plants of metallurgical industry; chromium and nickel iron ore oxidizing roasting; bauxite roasting in refractory plants and chamotte and aluminum hydroxide roasting in aluminium factory; chrome ore roasting in chemical plant. The lime kiln (i.e. active lime kiln) is used for roasting active lime and light burned dolomite for steel plants and ferroalloy works.

Rotary kiln incinerator Stucture:

1.There are 2 to 3 fulcrums on kiln. It is easy to ensure the contact surface of rollers and kiln tires parallel to the cylinder axis during installing;
 
2.There are specific gap between the tire and cylinder. It strengthens the cylinder by confining tires after thermal expansion;
 
3.The supports use rolling bearing which simplified bearing structure. It reduces energy losses during Kiln operation and makes it easier to maintain and repair;
 
4.In order to convenient installation and commissioning, there is a kiln slow rotating devices to maintain kiln nonconventional running operation while main transmission system is under overhaul or other abnormal conditions which can occur cylinder bending and deformation during the cooling process.
 
5.The kiln uses mechanical or hydraulic catching wheels. They are high accuracy and reliability. The ridding rollers and tires are evenly wearing on the entire width direction and are handy adjustment.;
 
6.The kiln head and tail uses elastic flake radial contact sealing. It can fit the cylinder shape inaccurate and kiln deflection & axial movement. It has better sealing performance and reliability, longer service life and convenient replacement.

Features and Advantages:
1. The main drive system uses the new AC speed governing technology. It has advantages of wide speed range, high efficiency, high precision and stable operation;
2. Rotary Incinerator is micro-negative pressure operation in the cylinder with low dust pollution;
3.Rotary Incinerator is even calcination, large capacity and easy to operation and maintenance.

Working Principle of rotary kiln:

Rotary Kiln is usually working as following : The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The raw material to be processed is fed into the upper end of the cylinder. While the kiln rotates, material gradually goes down towards the lower bottom, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal.
