Cement rotary kiln product introduction

Cement rotary kilns are widely used in the production and calcining of cement clinker. At present, the cement rotary kilns produced by our company are mainly cement clinker dry production line equipment. According to the different production processes of cement clinker, the products are divided into hollow dry kiln, kiln with preheater and kiln outside decomposition kiln, with a total of 16 models with diameter between 2.5m and 4.3m. It can meet the daily production range of 180-3200 tons of dry clinker calcination.

Cement rotary kiln is used for calcining cement clinker. Cement clinker calcination is the process of calcining cement raw material into cement clinker at high temperature, which is a very important production process in the cement production and manufacturing experience of "two grinding and one burning" (that is, raw material grinding, clinker calcination and cement grinding). One end of the rotary kiln is high, the other end is low, high-end feed, low-end discharge and coal feeding, and the clinker is calcined in the kiln in the process of continuous rotation.

Outstanding advantage

1, product stability: when calcining materials, the material can be heated evenly, and the product quality is stable;

2, transmission system: the main transmission system uses a new type of AC frequency conversion speed regulation technology, energy saving and environmental protection, and the speed range is large, high efficiency, high precision speed regulation, smooth operation;

3, tug device: single support wheel support device and stop wheel support device base welding is completed, after vibration aging treatment to eliminate welding stress, can improve the installation accuracy and reliability of the whole machine;

4, Optimize the structure: the overall structure of the kiln head and kiln tail section is optimized to solve the problem of kiln tail return and dust leakage, which is common in rotary kiln, and the transmission is more smooth and natural.

Working principle

The material enters the kiln from the end (high end), and due to the tilt and slow rotation of the cylinder, the material rolls along the axial and radial direction and gradually moves forward. The fuel is injected into the kiln from the kiln head (low end) through the burner for combustion, and the heat is transmitted to the material by radiation and conduction, and the material produces liquid phase in the process of moving, generating minerals such as tricalcium silicate, dicalcium silicate, tricalcium aluminate, and quadalcium ferroaluminate, completing sintering, generating clinker, and then discharging from the kiln head.

Installation and debugging of cement rotary kiln

After the purchase of cement rotary kiln, we need to carefully install and debug the equipment, which is mainly divided into the following parts:

1. Familiar with drawings:

Before installing the rotary kiln, it is necessary to familiarize yourself with the drawings, understand the water, electricity, road, and safety aspects of its office location, and determine the location of the power supply and temporary power supply.

2. Lifting and transportation:

In the installation process, because the cement rotary kiln is relatively heavy, we must make the best preparation for the lifting equipment, as well as the transportation and installation tools, but also prepare in advance for future trouble.

3. Personnel requirements:

Because the cement rotary kiln body is relatively large during installation, cross operation should be avoided during installation, because there is a certain distance between the rotary kiln and the ground when we arrange it, so we should pay special attention to safety aspects, and it is recommended to have safety supervisors for technical guidance, so as to get the best installation effect.
