Rotary kiln is a kind of equipment for heat treatment of bulk or granular materials. It has been more than 100 years since the invention of the rotary kiln. During this time, people have made countless transformations and redesigns of the use and structure of the rotary kiln, then the technology of rotary kiln equipment becomes mature. Today's rotary kilns have been widely used in non-ferrous metallurgy, ferrous metallurgy, refractory materials, environmental protection, cement, chemical industry, papermaking and other industries. But if you want to use a rotary kiln for heat treatment, you first need to ensure the rationality and reliability of its foundation. The following will introduce some related content of the rotary kiln foundation construction.

Before the installation of the rotary kiln, it is necessary to make preparations for the basic construction. Because the rotary kiln is a long equipment and each foundation is independent of each other, if the deviation between the foundation piers is large, it will have a great impact on the equipment installation. Therefore, the relationship between its foundations is particularly important.

It is necessary to make adequate preparations before foundation construction. First of all, when choosing the site of the plant, the groundwater system should be avoided as much as possible, and areas with solid soil or stone should be selected. Then professionals will carry out geological exploration to determine the geological conditions and submit them to the civil engineering design unit to check whether the load of the rotary kiln and its foundation is available here. If the results of the geological survey indicate that the firmness here is insufficient to support the rotary kiln and its foundation, the civil engineering design unit shall design the underground part of the foundation, for example, a whole raft or additional pile foundation under the rotary kiln foundation. Avoid settlement after foundation construction.

During the construction of the rotary kiln foundation, a settlement observation point must be left on the body of the kiln pier, and a reference point should be set at a location that is not easy to settle around, such as a wall, a mountain, etc. After the foundation is completed, the settlement observation points need to be regularly observed. Once the foundation is found to be subsidenced, construction or production must be stopped immediately, and please immediately invite a professional team to deal with the subsidence foundation, according to the different settlement conditions, choose reinforcement The foundation is to prevent it from continuing to settle, or to be reinforced after being lifted as a whole. If the foundation settlement of the rotary kiln is not discovered and handled in time, it may cause serious accidents such as the collapse of the kiln tail chamber or even the rotary kiln breakage.

As rotary type equipment, the basic accuracy requirements of the rotary kiln are also higher than other common equipment. Most common equipment is an overall foundation, and the foundation of the rotary kiln is composed of several independent foundations. Therefore, the relative positions of these independent foundations are very important. Generally, the construction and design errors must not exceed 20mm. Therefore, the foundation construction of the rotary kiln also tests the construction capabilities and technology of civil construction personnel.
