Volume of grinding tank (L): l: 0.5L × 20.25l × 20.1l × 20.05l × 2 ? 2 grinding groove material: Agate grinding medium material: the loading amount of each tank: material and grinding medium shall not exceed two thirds of the volume. What is the feed size of brittle material of muffler is less than 10 mm, and that of other materials is less than 3 mm. The minimum discharge particle size can be 0.1 micron (depending on the brittleness of different materials). Speed control mode: frequency converter stepless speed regulation transmission mode: gear transmission safety mode: safety switch (function is to open the door automatically stop) working voltage: 220 V ? motor power and frequency conversion power: 0.75kw ? working mode: two or four boxes work at the same time, continuous working time: fan muffler 48 hours (timer 0-999 hours) program control: ball mill is made of high-tech microcomputer core Slice control. According to the set program, it can run alternately in forward and reverse rotation (0-999 minutes) and forward rotation, pause, reverse, pause and forward rotation (0-999 minutes). It is suitable for circulation systems requiring cooling or intermittent operation. Circulation capacity: the flow rate of the integrated fan is more than or equal to 90m3 / h, which can be variable frequency. Users can freely set the opening or closing of the circulating system according to the oxygen content of water. 8. One control valve: integrated valve. 7 inch and above, color screen. The air blower muffler automatically records the water content and oxygen content of the box, and measures the leakage rate of the box.
