"Two-color ball" lottery machine is one of the most advanced lottery machines in the world, which was specially introduced by China Welfare Lottery Distribution Center from RYC- Cato Company. The machine is 2.02 meters high and 0.75 meters wide, which is more atmospheric than most lottery machines used in China. The appearance of the lottery machine consists of an upper part and a lower part, the lower part is divided into a base, and the upper part is divided into a circular transparent gravity ball receiver and ten ball introduction pipes side by side.
The "two-color ball" lottery machine adopts the bottom two-way stirring lottery mode, and the power is generated by two different steering mixing chassis, and the number ball is hit and stirred evenly. After stirring for a few seconds, a lottery ball will fall into the round hole below the gravity catcher, and winning numbers will be generated one after another. Due to the great power of the lottery machine, the colored balls are stirred by the bottom turbine and fly up and down in the ball catcher with a diameter of 0.75 meters. The scene is really beautiful, which will also become a beautiful landscape at the lucky draw.
The special numbered balls used in the "two-color ball" lottery machine are also patented products provided by RYC- Cato Company. The first ball is made of natural rubber and synthetic material, and its colors are bright red and dark blue respectively. Compared with the numbered ball similar to table tennis, it is harder, heavier and less prone to deformation. Each digital color ball has a diameter of 50 mm, and the numbers are marked with familiar characters. After vulcanization, the mass of each ball is 22 g, the diameter error between balls is between +-5/ 10 mm, and the rebound value is +-4%.
Because the "two-color ball" lottery involves shaking red and blue numbered balls from two lottery machines, each group of numbered balls has 33 red numbered balls and 16 blue numbered balls. This time, China Welfare Lottery Distribution Center introduced two lottery machines, each equipped with two sets of balls. Before each lottery, under the supervision of a notary, a group of balls will be randomly selected as the current lottery balls. And two sets of lottery machines will also appear in front of the lottery players at the same time, playing a role in winning the grand prize for the lottery players.
