Recently, the Inner Mongolia Rongxin project gasification unit ball mill under the general contract of Hualu Science and Technology Co.
, a subsidiary of China National Chemical Corporation had a successful single-unit test run, laying a solid foundation for the gasification unit to open up the process and put into trial production in October
.
This is the largest ball mill in China's coal chemical industry
.
??? The ball mill is one of the core equipment of the gasification unit, which grinds the coal from the coal preparation unit into pulverized coal
.
The project has a total of 4 overflow ball mills, breaking the convention of using rod mills in coal chemical projects in the past, increasing the fineness of coal powder and prolonging the service life
.
The size of the ball mill drum is φ5.
2*8.
5m, the rated power of the motor is 3800kW, the loading capacity of a single steel ball is 252 tons, the solid concentration is 56.
5-65wt%, the density of coal slurry is 1150-1250kg/m3, and the single output is 131t/h (air dry Base)
.
??? Hualu Technology Rongxin project team has overcome many difficulties.
Under the conditions of tight time and heavy tasks, all personnel carry forward the spirit of hard work and fighting, and often work overtime until late at night to ensure the test node of the ball mill
.
During the trial run, they completed a series of preliminary preparations such as qualified oil transport at the ball mill oil station, commissioning of the inverter, single test of slow drive, single test of main motor and single test of reducer
