Calcium aluminate is a high-grade raw material for bauxite and limestone kiln. Calcium aluminate does not absorb water and chalk, it does not deteriorate during storage and transportation so does mineral composition and pre-melted aluminum and calcium.
The original mine is directly fed into the tail of the calcium aluminum rotary kiln, which is delivered by the electronic belt meter, belt conveyor, belt conveyor, stabilizer and lock valve. First, the ore enters the calcium aluminate rotary kiln to be heated. The original mine in the kiln flows backward against the heat. In the heating area, the raw mine is heated to the reduction temperature and then be put into the reduction zone.
The temperature in the reduction zone is controlled at around 1000, and the temperature of the reduction area is controlled at 700 to create a reduction reaction with gas. Second, after the cooling zone, the core is cooled down then be ejected outside the kiln, and after the continuous bucket conveyor s water cooling, the ore is able to opt-in the storage.
Gypsum is the raw material commonly used in construction, building materials, chemical industry, metallurgy, coating, and other industrial fields. Gypsum is very different from natural gypsum, in which the utilization value of gypsum is higher and there are many ways to process it. The main processing technology is calcination, and the equipment to complete calcination is a gypsum rotary kiln.
The structure of the gypsum rotary kiln mainly includes the kiln head, kiln tail sealing device, supporting wheel device, retaining wheel device, supporting device, rotating barrel, coal injection pipe device, etc. The overall structure design is relatively reasonable.

Cement kiln, just as its name implies, it is known for its capability to deal with cement. It is a device for bedding for dry and wet cement clinker production. Cement kiln can also be widely applied in other sectors like metallurgy, chemical engineering, building refractory, environmental protection, etc. Cement kiln is composed of the barrel, supporting device, a support device with baffle wheels, gearing, active kiln head hood, kiln end sealing device, coal jet pipe device and so on.
Cement rotary kiln turns into micro running under high temperature. The maintain of attachment devices and the level of the thermal system is closely related to cement kilns safety and efficiency. The key points of caring and maintaining gearing are to checking lubrication, running status, dynamic detection and meshing precision between large and small gears. Installation accuracy of supporting device keep rotary kiln safe and smooth. Then, pay attention to the rational distribution of stay wheels bearing weight, layout form of riding wheels, hydraulic gears upstream and downriver pressure and time. The quality of stealing device directly affects the rotary kilns quality of the thermal system and operating cost. In one word, keeping routine maintenance and data analysis benefits the management of devices.
Cement kiln is an important device for the dry and wet cement production line. Cement kiln is mainly formed by barrel, gearing, roller support device, stop wheel support device, kiln lining, kiln tail seal, kiln head hood and fuel plant.
Cement kilns material of internal heating-type directly contacts with flame and smoke. So, the inside wall of kiln is laid by refractory bricks. Head and tail cover lining is made from wear-resisting, casting material. There is a flexible seal between the head and tail-cover and kiln, which prevents a kiln from raising dust and leaking.
Cement kilns material of external heating-type doesnt directly contact with flame and smoke. Heat source exists between heating furnace and kiln, heating material conducting heat through heat resistant steel cylinder wall. The lining of heating furnace is made from refractory fiber, which helps cement kilns energy-saving and cost-reducing.
Cement kiln puts raw material into kiln tail, raw material turning itself into cement clinker after a series of physical and chemical reaction because of kilns tilt placement and its rotary capability. Put cement clinker into the cooling machine after it ejected from kiln head hood. Dry rotary kiln makes the raw material into raw powder, whose water content is less than one percent. The advantage is that it saves more energy than a wet rotary kiln. The disadvantage is that it may happen that ingredient in mixed material is uneven.
Cement kiln turning raw into a slurry, whose water content is from 32 percent to 40 percent. The advantage of a wet rotary kiln is that the good liquidity of slurry makes better evenness leading to a higher quality of clinker.
AGICO is a comprehensive engineering and technology company that integrates cement engineering equipment and general contracting, cement rotary kiln, cement plant design, cement complete equipment export, supply of cement equipment parts, and maintenance of production line.

It is reported that the Uzbek customer before mainly engaged in oil-related products, due to development needs, began to invest in infrastructure construction. In order to expand the market share and increase profits, it was decided to build a cement plant and purchase a rotary kiln for cement manufacture. Since the project was put into operation in 2019, the entire rotary kiln cement plant has been running well, with a high automation level, convenient equipment operation, and extremely low failure rate.
1. Be familiar with a blueprint of the cement kiln. Comprehend cement rotary kilns concrete parameters, sub-units exact location and basic lines benchmark through the blueprint. Grasp the information about the transport route, working site, tool room, and temporary power supply through the layout chart.
2. Select good cement kiln hoisting equipment and transportation equipment. The device on the cement kiln-production line is generally large size and heavyweight, so the necessary hoisting equipment and transportation equipment should at least be on a broad scale. The selection, usage, maintenance of other tools such as steel wire rope, hemp rope, and the fixture should be in accordance with relevant provision. Fuel, cutter, and welding tools also should be prepared to make sure the success of the installation.
3. Require for professional for cement kiln. Cement rotary kiln has a short construction period and more work high above the ground because process equipment is at height. So, the characteristic of the installation of cement kiln is difficult and dangerous. That requires constructors should have fit bodies, a wide-scale of knowledge, skilled technology, and the ability to adapt to local conditions.
5. Debugging in a cement kiln. After the installation, check whether the technical indicators are qualified or not. Buyers should inspect the whole cement rotary kiln and its subsidiary facilities before any debugging. Details about debugging are below.
