Problems solved by technology

The starting torque of the ball mill is much greater than the normal operating load, which is the biggest operating characteristic of the ball mill. Due to this characteristic of the ball mill, the actual power of the driving motor is required to be much greater than the power during normal operation when selecting the type of the ball mill. High power After the ball mill works normally, the motor has excess power and is expensive, resulting in the phenomenon of large horse-drawn carts, which not only creates economic pressure for users, but also makes the allocation of resources unreasonable and wastes a lot of energy.

Embodiment Construction

[0019] The present invention is specifically described below in conjunction with accompanying drawing, as Figure 1-2 As shown, a permanent magnet direct drive ceramic mill throwing ball starting method includes a ball mill 1, a permanent magnet motor 2, a transmission mechanism and a controller 3, and is characterized in that the starting technique of the ball mill 1 includes the following steps: 1 ) The controller 3 starts the permanent magnet motor 2, and the permanent magnet motor 2 drives the ball mill 1 to rotate in the forward direction; 2) When the permanent magnet motor 2 reaches its maximum output power and the ball mill 1 does not meet the rotation condition, the controller 3 automatically controls the permanent magnet motor 2. Reverse acceleration rotation; 3) When the permanent magnet motor 2 reaches its maximum output power again and the ball mill 1 does not meet the rotation condition, the controller 3 controls the permanent magnet motor 2 to accelerate forward r...

Abstract

The invention provides a permanent magnetic direct drive ceramic mill ball throwing starting method. The problem that large torque is needed when a ball mill is started is solved. Aiming at the characteristic of the ball mill during starting, an energy accumulation principle is adopted, energy of the ball mill is promoted gradually, and thus the condition enabling the ball mill to rotate is achieved. The permanent magnetic direct drive ceramic mill ball throwing starting method has the beneficial effects that structure is simple, and practicability is high .

Description

technical field [0001] The invention relates to the field of ball mill drive, in particular to a ball-throwing starting method for a permanent magnet direct drive ceramic mill. Background technique [0002] The ball mill is an indispensable equipment in the cement industry, ceramic industry, and mine beneficiation industry, and it is also one of the equipment with the largest power consumption in these three industries. The starting torque of the ball mill is much greater than the normal operating load, which is the biggest operating characteristic of the ball mill. Due to this characteristic of the ball mill, the actual power of the driving motor is required to be much greater than the power during normal operation when selecting the type of the ball mill. High power After the ball mill works normally, the motor has excess power and is expensive, resulting in the phenomenon of large horse-drawn carts, which not only creates economic pressure for users, but also makes the al...
