Description

Jaw Crusher

technical field

The utility model relates to the field of powder-making process equipment for preparing NdFeB permanent magnet materials, more specifically, it relates to a jaw-type coarse crusher.

Background technique

Since its invention in the 1980s, NdFeB permanent magnet materials have developed rapidly due to their excellent magnetic properties. At present, the application of NdFeB permanent magnets has penetrated into automobiles, household appliances, electronic instruments, nuclear magnetic resonance imaging instruments, audio equipment, micro motors, mobile phones, etc.

When producing NdFeB permanent magnet materials, it is necessary to follow the process route of batching-smelting-powder-making-molding-sintering-aging. The powder-making process is an important stage in the production of NdFeB permanent magnet materials, generally divided into two steps To complete, the first step is coarse crushing of magnets, crushing magnets into particles with a particle size of less than 2mm, and the second step of jet milling is to crush coarse particles into fine particles with an average particle size of 2-5 μm.

The coarse crushing process of magnets often chooses the mechanical crushing method, that is, the crusher is used to crush the magnets. The principle of this equipment is to crush the magnets into small particles with a high-speed rotating hammer, and then use a suitable size screen to collect the qualified small particles. . However, when collecting magnetic powder, because the magnetic powder particles are small, they are easy to agglomerate at the discharge port of the crusher. It is often necessary for someone to poke the discharge port to help the magnetic powder enter the receiving barrel, which affects the process of the operation.

Utility model content

Further optimization is: a jaw crusher, the driving device includes a driving motor, the rotating shaft of the driving motor is provided with a driving gear, and the outer wall of the cylinder is surrounded by meshing teeth that mesh with the driving gear.

Through the above technical solution, the driving motor drives the driving gear to rotate, and the driving gear drives the cylinder to rotate through the meshing teeth, so that the cutting machine structure on the inner wall of the cylinder can rotate 360 degrees and contact the magnetic powder, solving the problem of reunion of magnetic powder in each corner, so that The magnetic powder falls into the receiving bucket better.

Further optimization is: a jaw crusher, the cutting structure includes cutting blades arranged on the inner wall of the cylinder.

Through the above technical solution, the cutting blade can chop the magnetic powder agglomerated at the discharge port into small pieces, prevent blockage caused by agglomeration, and make the magnetic powder fall into the material receiving barrel better.

Further optimization is: a jaw type coarse crusher, the cutting blades are evenly spaced on the inner wall of the cylinder, and there are 6 cutting blades in total.

Through the above technical scheme, if the cutting blade is set too much, not only the magnetic powder cluster cannot be well chopped, but also the magnetic powder cluster will be further blocked. If the cutting blade is set too little, the blade will not have time to break all the magnetic powder clusters, so the reasonable logarithm Advanced cutting blades, such as 6 pieces, can better break the magnetic powder clusters and ensure that the magnetic powders all fall into the receiving bucket.

Further optimization is: a jaw type coarse crusher, the cutting blade and the cylinder wall form an angle of 60-75°.

Through the above technical solution, the cutting blade forms a certain angle with the cylinder wall, and it is more convenient to bear force when cutting the magnetic powder cluster, which can better chop the magnetic powder cluster, and effectively solve the problem of blockage of the magnetic powder cluster.

Further optimization is: a jaw type coarse crusher, the cutting blade is made of stainless steel.

Through the above technical solution, the blade made of stainless steel has high hardness, high strength, and light weight, and can better cut the magnetic powder cluster when rotating together with the cylinder wall.

Further optimization is: a jaw type coarse crusher, the lower end of the discharge port is provided with a receiving barrel, and the auxiliary unloading device is connected to the receiving barrel through a flange.

Through the above technical solution, the feeding device is connected to the receiving barrel through the flange, which effectively ensures the sealing of the entire feeding process, so that the magnetic powder will not be scattered outside the device and lost.

Compared with the prior art, the utility model has the advantages that: a jaw type coarse crusher, by setting an auxiliary blanking device at the discharge port, the device includes a cylinder that is rotatably connected with the discharge port, and the cylinder is formed by A driving gear drives the rotation, and a cutting blade is installed in the cylinder to crush the material again. When the external driving gear drives the cylinder of the auxiliary feeding device to rotate, the cutting blade on the inner wall of the cylinder will cut the agglomerated magnetic powder Crushing ensures that the magnetic powder falls well into the borrow barrel, effectively solving the problem of blockage caused by the agglomeration of magnetic powder on the discharge port, improving the working process of the crusher, and improving the working efficiency of workers.
