Lime kiln drives are no exception, are: the main motor, main gear, pinion, ring gear, auxiliary motor, auxiliary gear and other components. These devices are carrying the entire operation of the main unit rotary kiln production, the lack of any one of the whole system will not run. In the calcination of limestone in the process, these devices how to choose and use the following rotary kilns in Henan YuFeng Heavy technician doing eleven explanation: 1, select the drive motors require kiln main motor speed, burnt lime rotary kiln speed range is generally 1:10. Kiln starting torque, starting is often carried out under full load, then the roller bearing oil film is not formed, the resistance moment is also large, usually starting torque is a normal torque 3.5 a four-fold. 2, commonly used motor and speed control method (1) DC motor. DC motor speed range, enabling smooth speed, smooth start, startup performance, enabling the automation of the kiln operation. DC motor speed below with the basic magnetic transfer speed, this time for the constant power speed, you can get a lot of time at low starting torque; adopt the above base speed voltage control, constant torque speed. (2) AC variable frequency induction motor. Frequency control in recent years, been widely adopted. Rotary kiln dedicated inverter motor starting characteristics to meet requirements, but should be considered an ordinary inverter motor larger power margin, speed range up to 1: 10, 50Hz following constant torque speed, 50Hz or more for the constant power speed, in which case the output torque of the motor in order to maintain constant, requires a corresponding increase in the power of the motor. (3) AC Electromagnetic Induction Motor, to achieve a smooth stepless 1:10. The kind of motor efficiency is low, especially at low speeds, poor starting performance, to increase the power of higher margin, only occasional small size of the rotary kiln application. 3, rotary kiln with reducer reducer according to the design and manufacture our current situation, commonly used hardened cylinder gear reducer with high service life and light weight, small size. Kiln load is characterized by continuous, smooth, not always start, select reducer operating power shall be calculated, considering the conditions, temperature and other factors, should not exceed the allowable input power reducer, but also consider the allowable thermal power. 4, gears, gear ring gear, ring gear generally use spur gears, helical gears in recent years, there are some applications. In order to improve the strength of the tooth, the foreign multi-use 25 ° pressure angle. In order to improve the smooth transmission, the gear has been reduced modulus than before, in order to increase the number of teeth to increase the engagement degree of coincidence. Gear tooth wear is mainly caused by sliding to the pinion root as the most important, can be positive correction to your attention is the use of angular displacement gear meshing contact ratio will decrease due to decreased Such an approach the benefit obtained, which is more significant for the helical gear. At four o'clock complete explanation of the lime kiln gear in the process of selecting and using some of the techniques, for those who want to understand calcined limestone production line customer, you can look at these data, for the selection of equipment and subsequent operation has a certain Help.
