Traveling grate machine is a kind of thermal equipment working under high temperature environment, and its main parts are made of heat-resistant alloy steel. The working mode is to distribute iron pellets on slow running grate bed, use the waste heat of annular cooler and hot air flow from rotary kiln to dry, preheat, oxidize and solidify green pellets, and then directly send them to rotary kiln for roasting. The powder created in the production process of traveling grate machine is collected by ash hopper and will be reused.
According to different conditions such as operating conditions, temperature, material ratio and overall process of the equipment, traveling grate machine can be categorized into three types: oxidation pellet traveling grate machine, metallized pellet traveling grate machine and low-temperature reduction traveling grate machine; According to different output, it can be divided into equipment models with different specifications and output range of 0.1~5 million tons/year.
In 1996, our company began to develop traveling grate machine rely on domestic experts. In 1997, we successfully designed and manufactured a 200000 tons/year oxidized pellet traveling grate machine. After years of continuous research, development and design improvement, we are now able to design and produce various types of traveling grate machine from 01 to 2.4 million tons/year.
In more than 20 years of designing, manufacturing, installation, production guidance and other practices, our company has mastered the heat-resistant material technology, shovel plate technology, kiln tail sealing technology, transmission device technology, grate bed expansion technology, complete machine structure technology, installation technology, production and operation technology and fault handling technology, which can ensure the stable operation of the equipment.
