Mill roll from the automatic control system is mainly made up of quality test kits rolling distance control system, among them, the detection system is the auxiliary system. Can be reasonable to detect material constant, with the fastest speed to get are the basic parameters of grinding material, then we can according to different materials, to target regulation of Raymond mill grinding system
A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.
Mill Speed - Critical Speed. Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product. Too fast and inefficient media movement (known
regulation, monitoring and control, com-bined with advanced process technology, ensure reliable and efficient operation of the plant. Because of the short material dwell time in the mill, the machine settings can be quick-ly altered by the touch of a button, making the process easy to control and permitting rapid compensation for fluctuations in the properties of the feed material. Further
Rotation speed of the cylinder. Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.

Principal dimensions Basic load ratings dynamic static Fatigue load limit Speed ratings Reference Limiting speed speed Open the catalog to page 9 SKF stainless steel deep groove ball bearings are available for shaft diameters from 0,6 to 50 mm.
The speed of the mill was kept at 63% of the critical speed. The face angle was varied from 90 to 111 degrees for the three types of configuration 1, 2 and 4, as shown in the figure. Also, the height of the lifter bar in configuration 3 was changed to observe the trajectory. It was observed that the ball trajectories could be controlled by the face angle and the height of the lifter bars.
This regulation was extremely important, maintaining an appropriate speed for the machinery and preventing a surge in power which could permanently damage the equipment. It might look simple, but it was a very important part of protecting the machinery within a mill.
