Roller kiln

The structure of this roller kiln is box structure. According to functions of each part, the kiln can be divided into 7 parts: steel structure part, refractory material structure part, pipeline system, firing system, gas or oil pipe, transmission system, temperature controlling system, and safety system.

Refractory and Heat Preservation Materials of the Kiln

The selection of the refractory and heat preservation materials is according to the temperature requirement of different kiln sections. In order to ensure the life of the kiln, higher level than temperature requirement of the materials is to be selected. To reduce the energy consumption, it's better to select materials with low heat conduction coefficient.

Refractory and Heat Preservation Materials of the Kiln

After filtering impurities by the system and through leveling off the voltage, the gas/oil enters the burner by auto controlled valve. Many burners are interlaced collocated on the body of the kiln, and make the heat source of the kiln even and easy to adjust. 4-8 burners are set at every part of the firing parts. These burners are interlaced collocated to the kiln. 6-8 branch burners are set to be one group, adopting intelligent instrument and upper machine to auto control.
    Firing system considers the characteristics of the fuel. Safety shutting off valve, voltage leveling off valve and electromagnetism valve are set at the main pipe. When gas pressure oversteps the setting or power cut, the valve cut the supply of the gas automatically.
    Each control loop can control 6 or 8 burners. Set the roller as the border, the upper and lower burner controls separately to adjust the up and low difference of temperature. The section of the kiln chamber sets upper fire resisting plate and low fire resisting wall. Space between the fire resisting plate and the roller can be adjusted according to demand. The function is to adjust the burning curve according to technical demand, and can improve the temperature equality of the section.

Transmission System

The whole kiln adopts 45 ° bevel wheel driving method. Every 3 kiln sections forms a driving group, each with a decelerating motor, dragging by motors and with transducer control for tile ' s distance control. The whole kiln consists of 3 groups of transducers for controlling the distance of the tiles. The driving system has the functions as follows: switch of supply power and generating power, group driving swing function, supply power driving function without transducers. It has the advantages of steady, reliable driving, low faults, long life and wide range of speed adjustment.
