1.2 working principle

A rotary table is equipped with four ball milling tanks. When the rotary table rotates, the ball milling tank rotates around the main disk axis and reversely rotates around its own axis. The grinding balls and materials in the tank collide, shear and rub with each other in the high-speed movement, so as to achieve the purpose of crushing, grinding, mixing and dispersing materials. The equipment can grind all kinds of solid particles, suspensions and pastes with different particle sizes and materials by dry and wet methods. The minimum particle size of grinding products can reach 0.1 μ M.

1.3 equipment classification

According to the equipment structure and function, our planetary mill is divided into four types: vertical planetary mill, horizontal planetary mill, omni-directional planetary mill and double planetary ball mill.

Description of vertical planetary mill

2.1 introduction to vertical planetary mill

The vertical square planetary mill is a necessary device for mixing, fine grinding, sample preparation, new product development and small batch production of high-tech materials. Our vertical planetary ball mill has small volume, complete functions, high efficiency and low noise. It is an ideal equipment for scientific research institutions, universities and enterprise laboratories to obtain research samples (four samples can be obtained at the same time in each experiment). Equipped with vacuum ball mill, it can grind samples in vacuum.

No load commissioning operation steps:

① Turn on the power supply and turn on the air switch;

② Adjust the speed adjustment knob of variable frequency governor (3-1) counterclockwise to the maximum position;

③ Start the emergency stop switch (3-2) (the emergency stop switch is used to disconnect the power supply for shutdown in case of emergency, ④ it is disconnected when pressed, and it is started when rotating clockwise and popping up), and check whether the variable frequency governor (3-1) has a digital display (no display: check whether the power connection is in place; if there is a display: proceed to the next step);

⑤ Press the start button (3-3) to start the equipment, check whether the speed display of the variable frequency governor (3-1) is set to zero, slowly rotate the speed adjustment knob of the variable frequency governor (3-1) clockwise to regulate the speed to 1/2 of the rated maximum speed of the equipment, and conduct a test run for 5 minutes;

⑥ If no abnormality is found, adjust the speed adjustment knob of variable frequency governor (3-1) to zero, press the stop button (3-4) and emergency stop switch (3-2) respectively, cut off the power supply and shut down the equipment.

Precautions: some models of QM series planetary mill are not equipped with air switch.

2.5.2 ball loading

4-1. Ejector rod; 4-2. Locknut; 4-3. Beam; 4-4. Ball mill tank; 4-5. Grinding tank seat;

In order to obtain the best ball milling effect, large, medium and small balls are usually used together. Large balls are used for counterweight, crushing materials and dispersing small balls. Small balls are used for mixing and grinding materials. Under normal conditions, the total volume of balls and materials shall not exceed 2/3 of the total volume of ball milling tank (4-4).

Precautions:

in order to prevent the grinding balls and materials from falling into the equipment, resulting in the wear of gears and bearings, please first load the grinding balls and materials into the ball milling tank (4-4), and then install the ball milling tank (4-4) filled with materials into the grinding tank seat (4-5). It is not allowed to install the empty tank first, and then load the balls and materials into the tank.

2.5.3 canning

Canning operation steps:

① First, place a rubber pad at the bottom of the grinding tank base (4-5);

② Place the ball milling tank (4-4) loaded with grinding balls and materials into the grinding tank seat (4-5);

③ Insert the cross beam (4-3) of the grinding tank jacking device into the corresponding position of the grinding tank seat (4-5);

④ Tighten the ejector rod (4-1) to fix the ball mill tank (4-4) in the tank seat (4-5);

⑤ Finally, tighten the locknut (4-2) to make the whole device in the jacking state. matters needing attention:

① The ball mill tanks (4-4) must be installed symmetrically. It is forbidden to operate a single tank or three tanks. The total weight of the symmetrical two ball mill tanks (mill tank weight + ball weight + material weight) should be consistent as far as possible;

② The bottom center of ball milling tank (4-4) shall be consistent with the center of grinding tank seat (4-5) as far as possible;

③ Sufficient locking force must be ensured when tightening the ejector rod (4-1) and locknut (4-2).

2.5.4 power on standby

After the equipment is powered on, turn on the air switch and start the emergency stop switch (3-2) (rotating clockwise and popping up), the variable frequency governor (3-1) has a digital display, and the equipment enters the power on standby state.

2.5.5 setting frequency converter parameters (see operation instructions for frequency converter of planetary mill for details)

2.5.6 abrasive

After setting the functional parameters of the frequency converter, close the machine cover, press the start button (3-3) to start the equipment, slowly rotate the speed adjustment knob of the frequency converter (3-1) to adjust to the set speed, and start abrasive.

matters needing attention:

① Please open the machine cover after 5 minutes of operation of the equipment and check whether the top fastening device of the grinding tank is loose. If it is loose, it must be locked again;

② The speed displayed by the frequency converter is the rotation speed and the actual speed of the ball milling tank;

③ The higher the rotating speed is, the better the ball milling effect may not be. The higher the rotating speed is, the faster the wear of the mechanical parts of the equipment will be and the shorter the service life of the equipment will be. It is recommended that the user reduce the ball milling speed as much as possible according to the actual needs of the materials;

④ During the operation of the equipment, the user must strengthen the patrol inspection of the equipment. In case of any abnormal operation of the equipment, please stop the machine in time for inspection.

2.5.7 shutdown

After the equipment runs for the set time, adjust the speed adjustment knob of the variable frequency governor (3-1) to zero, press the stop button (3-4) and the emergency stop switch (3-2) respectively, cut off the power supply and shut down the equipment.

Precautions: after the speed control knob on the frequency converter is adjusted to zero, the equipment is still in the power on standby state. You must press the stop button (3-4) and the emergency stop switch (3-2) and cut off the power supply.

2.5.8 tank unloading

① Open the machine cover;

② Loosen the jam nut (4-2);

③ Loosen the ejector rod (4-1);

④ Remove the jacking device;

⑤ Finally, take out the ball mill tank (4-4);

Precautions: due to the heavy ball mill tank, it is inconvenient to manually load and unload the medium and large planetary mill equipment. Customers can purchase the loading and unloading lifting device of the corresponding planetary mill according to their needs.

2.5.9 unloading

Pour the materials and grinding balls in the ball milling tank into the ball and material separation device (purchased by the customer) for ball and material separation.

2.5.10 equipment cleaning

Clean the ball mill tank and ball before use, and wipe the equipment from inside to outside with a clean cloth.
