DETAILED INTRODUCTION
Product Introduction
Rotary kiln refers to a rotating calcining kiln (commonly known as a rotary kiln), which belongs to the category of building materials equipment.
Rotary kilns can be classified into cement kilns,metallurgical and chemical kilns, and lime kilns based on the types of materials they process.
Cement kilns are mainly used for calcining cement clinker, and are divided into dry process cement kilns and wet process cement kilns.
Metallurgical and chemical kilns are mainly used for magnetic roasting of iron ore in steel mills, oxidation roasting of chromium and nickel ores;
Roasting of high-alumina feldspar in refractory material factories and calcining of clinker and aluminum hydroxide in aluminum factories;
And roasting of chromium sand and chromium powder in chemical factories, etc.
Lime kilns (also known as active lime kilns) are used for roasting active lime and light-burning calcite used in steel mills and iron alloy factories.
Main Structure
Kiln-head section: The kiln head is the discharge end of the rotary kiln, with a diameter larger than that of the kiln body. It is sealed against the kiln shell by stainless-steel fish-scale plates, and its main components include an inspection port, coal-injection nozzles, a carriage, and observation ports. Kiln-body section: The kiln body is the main structural component of the rotary (or rotating) kiln, typically 30 to 150 meters in length and cylindrical in shape, with 35 supporting rollers evenly spaced along its circumference. The kiln shell is usually prefabricated in the factory into 310 segments, which are then transported to the installation site by heavy-duty trucks and assembled on-site by welding. The supporting rollers, also known as “tire rings,” are cast from molten steel; due to their load-bearing function, the steel plates used for this section are slightly thicker than those of other parts of the kiln shell. The support rollers, which are integral to the kiln body and correspond to the supporting rollers, are connected to the foundation and serve as the primary load-bearing supports for the entire rotary kiln. A typical set of support rollers consists of two support rollers and two thrust rollers. During normal operation, the interior of the rotary kiln is lined with refractory bricks. Kiln-end section: The kiln end is another critical component of the rotary kiln. At the feed end, it resembles a lid for the kiln and primarily serves to receive the feed material and provide a seal. Other associated equipment includes the kiln-supporting frame, preheater tower, cooler, and conveyor belts.
