Ball pressing is when the attacker's body is in an ascending state when the attacker is preparing to shoot but has not yet made a shooting action, the defender presses his hand on the ball (without touching the attacker), so that the attacker cannot throw the ball.
Pressing the ball is one of the basketball terms. Ball pressing is when the attacker's body is in an ascending state when the attacker is preparing to shoot but has not yet made a shooting action, the defender presses his hand on the ball (without touching the attacker), so that the attacker cannot throw the ball. Basketball is not a foul when the ball is pressed, and if the attacking team has jumped up and does not throw the ball and land, it is considered to be carrying the ball and should be transferred.
When playing passerby basketball, such a defense is generally called a foul, and it is actually not a foul. However, the general pressure ball comes with the beater, so when playing passerby basketball, the opponent's call for the ball is basically equivalent to the meaning of the beater's foul.

There are two main ways to form the ball, one is to form by the cohesion between the particles, such as the disc balling method, which requires the use of a disc balling machine; The other is to apply pressure to the powder by external force to make it form a ball, and the ball press is mainly used to pressurize it. 1. Disc Pelletizing Machine Disc pelletizing machine has the advantages of uniform ball formation, easy control of ball moisture, high strength, simple structure, convenient control, low kinetic energy consumption and stable operation. In the working process, under the condition that the powdery material has a certain humidity, the tray is constantly rotating to make the outer layer of the larger particles continue to stick to the powder, so as to increase the size of the spherical particles to achieve balling, the main characteristics are as follows: >>>More

Ball rubbing is the basic technique of catching the ball with downspin. In order to ensure the stability of the ball, we should pay attention to the following points during the practice: first, use the elbow as the fulcrum to complete the batting action; second, the wrist is relatively fixed; Thirdly, the forearm is placed horizontally in front of the body when the shot is directed backwards (Fig. 5). Fourth, when hitting the ball, rely on the small movement of the wrist forward to strengthen the friction of the ball (Diagram 6-7). >>>More
