Permanent Magnet stirrer

Permanent Magnet Stirrer is a stirring equipment/mixing machine that widely applied in the aluminum etc metal
molten industry when melting. The permanent magnetic stirrer is an alternating magnetic filed producer which is
made up of special permanent magnet.

Operating Principle of the magnetic stirrer:
Permanent Magnet Stirrer would make the alternating magnetic field when permanent magnet working, then to stir
and mix the metal molten. There are equipped with multi-level magnetic fields in the permanent magnet stirrer,
which can produce the waving and alternating magnetic field drove by the motor, the magnetic filed and the
aluminum etc metal would produce the inter-active magnetic acting force---the metal would be mixed and stirred
drove by the magnetic working force.

Composition of the Permanent Magnet Stirrer:
a. Special permanent magnet
b. Air cooling system
c. Auto lifting system
d. Electric control system

Mounting methods of the Permanent Magnetic Mixing Machine:
Bottom Mounted (under the aluminum melting or holding furnace)
Side Mounted (Beside the aluminum melting or holding furnace)

Application of the Permanent Magnet Stirrer:

5MT-60MT Aluminum Melting furnace and Holding Furnace for aluminum alloy or high purity aluminum industry,
aluminum scraps recycling industry etc.

Advantages of the Permanent Magnet Stirrer:
1. Making the chemical composition of the molten metal much more well-distributed and balance
2. Non-contacting mixing and stirring mold, avoiding being “Secondly polluted” the molten metal. It is the reliable
technical guarantee of the high purity aluminum industry and the aluminum alloy industry that need to strictly
control the trace element
3. Shorten the melting time, speed up the melting speed, much more high efficiency and energy saving. The
Permanent Magnet Stirrer can be started mixing when there is about 1/3-2/3 molten , speeding up the heat
exchange between the molten metal and non-melted raw materials. It can improve the melting speed: 13%-20%;
energy saving: 15%-24%; lowering the burning loss: 0.5%-2%
4. Making the temperature of the molten metal much more uniform. The difference between the surface and bottom
of the molten metal can be controlled within 5-8 ceni degree, which can avoid the molten over-burning because of
over high temperature
5. Improve the purity of the molten metal. The molten metal is mixing when stirring, which can help the non-metal
impurity and gas liberate
6. It can reduce the oxidation sludge, so as to reduce the furnace cleaning frequency , extend the using life of the
furnace
7. The permanent magnet stirrer can help the oxidation sludge gather on the surface of the molten, which is good to
slag-off and down the labor working force
8. It is sturdy and durable, long using life---more than 8 years.
9. High reliability& energy-saving, free-maintenance ,free-pollution
