Technical Field

Background
A ball mill is an ore mill that can crush materials after they are crushed. This type of mill is called a "ball mill" because a certain number of steel balls as a grinding medium are loaded in a cylinder to pulverize a material. The ball mill is suitable for grinding various ores and other materials, and is widely applied to the industries of mineral separation, building materials, chemical industry and the like. Because the ball mill needs to grind ore and other materials, the ball mill often has the problem such as barrel jam.
In order to repair the above problems of the ball mill, it is necessary to control the driving speed of the cylinder of the ball mill, which requires a driving control means. The transmission control device is provided with two control operations of positive rotation and reverse rotation, which are respectively used for controlling the positive rotation and the reverse rotation of the ball mill cylinder, and the two actions are controlled according to the field requirements.

When the breakers QF1 and QF2 are closed, the whole control loop is connected, when the ball mill needs to be controlled to continuously run according to the forward rotation normally open contact SBF, the forward rotation contactor KMF is electrified, the contact KMF1 of the KMF is closed to complete circuit self-locking, and the ball mill continuously runs forward; when the ball mill is controlled to rotate reversely, the reverse rotation contactor KMR is electrified when the reverse rotation button SBR is pressed, the contact KMR1 is closed to complete circuit self-locking, and the ball mill continuously rotates reversely.
