Principle 1: Put more than n objects into n-drawer, then at least one drawer in less than two.
Reference (contradiction): If each object into a drawer at best, the maximum total number of objects is n, rather than title set n + k (k ≥ 1), it is not possible.
Principle 2: Put more than mn (m times n) of n objects into a drawer, then at least one drawer of not less than m +1 objects.
Proof (reductio ad absurdum): If each of m objects into the drawer up, then up into the Magnetic Grate n mn of objects, with the title set does not match, it is impossible.
Principle 3: infinitely many pieces of objects into n drawers, at least one drawer with an infinite number of objects.
Principle 1, 2, 3 are schematic representation of the first drawer.

Product description and schematic manner magnet
Adaptation: magnetic filter rods (magnet) mainly used to remove powder, granular and liquid or slurry ferromagnetic impurities, widely used in ceramics, electricity, mining, plastics, chemicals, rubber, pharmaceutical, food, environmental protection , pigments, dyes, electronics, metallurgy and other industries.
Product description and schematic manner magnet
Adaptation:
Magnetic filter rods (magnet) mainly used to remove powder, granular and liquid or slurry ferromagnetic impurities, widely used in ceramics, electricity, mining, plastics, chemicals, rubber, pharmaceutical, food, environmental protection, paint, dyes, electronics, metallurgy and other industries.
How it works:
Magnet is made of high quality stainless steel and high alloy NdFeB rare earth B values, and using a special production method is made. The holder can be combined in forming the Magnetic Grate filter. When the ferrous material through when attracted by the magnetic bar, a substance containing iron magnet firmly adsorbed on the wall, in order to ensure the integrity of equipment and product safety.
Product Features:
No energy, no pollution, can be installed on the production line can be anywhere in contact with the material, space-saving, easy installation, as a magnet NdFeB rare earth alloy magnetic source, strong magnetic force, simple structure, long life, specification style can be in accordance with customer requirements and production scene arbitrarily change the custom.

planar magnetic scale linear magnetic tape and magnetic
f planar magnetic scale linear magnetic tape and magnetic tape two kinds of coaxial line.
Planar linear magnetic tape
The magnetic tape and metal engraved lines have a structure similar to the feet of A and strip aperture similar. Magnetic tape strip is installed with a special metal frame. Magnetic tape the tape-shaped metal bracket with a certain tension to the stress of the middle of the frame or support, the magnetic scale and the thermal expansion coefficient of the machine frame or close to the thermal expansion coefficient. The work head and the Magnetic Grate tape contacts, magnetic tape as a flexible strip, to allow a certain deformation. This magnetic tape can be done relatively long, generally do more than 1m in length. Coaxial linear magnetic tape This is a round rod of 2mm in diameter made of magnetic tape, the head is a special structure, it is the bag in the middle of magnetic tape, the track is a multi-gap type magnetic head in response. The advantage of this structure is the output signal, high accuracy, good anti-jamming, the disadvantage is not easy to do for a long (typically 1.5m less), thermal expansion coefficient, usually applied to small precision machine tools and measuring machines.

permanent magnet drum magnetic separator - Features
1 The same cylinder can be equipped with three types of tanks, to adapt to different sorting process.
2 half countercurrent tank for the ore particle size of 0.5-0mm strong magnetic minerals wet roughing and, especially for large particle size of 0.15 ~ 0mm selection of mineral.
3 countercurrent tank for ore particle size 0.6 ~ mm ferromagnetic minerals wet roughing and scavenging. Especially for heavy medium coal preparation plant recycling.
4 downstream slot for the ore particle size of 6 ~ 0mm crude selection and selection.
5 half countercurrent tank and downstream slot can be used in tandem to improve the concentrate grade.
6 ferrite Magnetic Grate using high-quality rare earth magnets or composite material made of tube sheet average magnetic flux density is 100 ~ 600mT.
According to user needs, providing downstream, semi-counter, and a variety of different tables and strong magnetic separator. Our products has a simple structure, large capacity, operating
Convenient, easy to maintain.
