I. Overview:
SFJ-400 sanding, dispersing and mixing multi-purpose machine (frequency conversion speed regulation) is a product independently developed by our company. It integrates multiple functions of sanding, dispersing and mixing, and is a satisfactory choice for chemical laboratories. This machine adopts a special frequency conversion motor, low heat generation, no brush; the frequency converter adopts a multi-turn speed control knob, and the display screen directly displays the stirring speed, which is easy to operate; there are a variety of optional sanding, dispersing, and stirring blades, which can be used Adapt to different test requirements.

3. Use and maintenance
l. Select the appropriate blisk and screw it to the stirring shaft.
2. Loosen the lifting and locking handle, adjust the height of the blisk and the bottom of the mixing drum (can be positioned with a positioning ring), and then raise the stirring shaft for feeding and placing the mixing drum.
3. Position and fix the mixing drum with the Y-shaped holder.
4. Lower the stirring shaft to an appropriate position, cover the mixing drum cover, and tighten the lifting and locking handle.
5. Confirm that there is no contact between the blisk and the mixing drum, and then start stirring. For details on the operation of the inverter, refer to "Inverter Panel Operation Instructions" (attached).
6. After the stirring is completed, first lower the stirring speed appropriately and then press the stop button.
7. Please clean and maintain the blisk, mixing drum and host equipment in time after each work, so as to facilitate subsequent use.
8. This machine is used in the testing process of chemical products. Before using it, users should establish appropriate safety and health protection measures and determine rules and regulations according to relevant safety regulations. Safety issues related to contact with chemical raw materials should be established by the user and are not within the scope of this manual.
Precautions:
1. The speed of the stirring shaft is controlled by the speed control knob on the frequency converter (rotate clockwise for acceleration); before starting the stirring shaft to rotate, please confirm that the rotating speed is at a low speed position (to avoid the splash of the material liquid caused by too fast rise), after starting Then use the speed control knob to quickly adjust to the appropriate position.
2. Before stopping the stirring, it is advisable to reduce the stirring speed appropriately, and then press the stop button, so as to avoid flying liquid caused by too fast rise in the next startup.
3. The inverter parameters have been set before leaving the factory, please do not change them at will.
