Graphite ultrafine grinder

The most common way graphite is recycled occurs when synthetic graphite electrodes are either manufactured and pieces are cut off or lathe turnings are discarded, or the electrode (or other) are used all the way down to the electrode holder. A new electrode replaces the old one, but a sizeable piece of the old electrode remains. This is crushed and sized, and the resulting graphite powder is mostly used to raise the carbon content of molten steel. Graphite-containing refractories are sometimes also recycled, but often not because of their graphite: the largest-volume items, such as carbon-magnesite bricks that contain only 15–25% graphite, usually contain too little graphite. However, some recycled carbon-magnesite brick is used as the basis for furnace repair materials, and also crushed carbon-magnesite brick is used in slag conditioners. While crucibles have a high graphite content, the volume of crucibles used and then recycled is very small.
Graphite (carbon) fiber and carbon nanotubes are also used in carbon fiber reinforced plastics, and in heat-resistant composites such as reinforced carbon-carbon (RCC). Commercial structures made from carbon fiber graphite composites include fishing rods, golf club shafts, bicycle frames, sports car body panels, the fuselage of the Boeing 787 Dreamliner and pool cue sticks and have been successfully employed in reinforced concrete, The mechanical properties of carbon fiber graphite-reinforced plastic composites and grey cast iron are strongly influenced by the role of graphite in these materials. In this context, the term "(100%) graphite" is often loosely used to refer to a pure mixture of carbon reinforcement and resin, while the term "composite" is used for composite materials with additional ingredients.
Graphite has been used in at least three radar absorbent materials. It was mixed with rubber in Sumpf and Schornsteinfeger, which were used on U-boat snorkels to reduce their radar cross section. It was also used in tiles on early F-117 Nighthawks. Modern smokeless powder is coated in graphite to prevent the buildup of static charge.

Working Principle of Graphite ultrafine grinder:
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
Production Line Configuration of Graphite grinding mil:
crushing machine, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems.

Features of Graphite ultrafine grinder:
1. High efficiency
At the status of the same finish fineness and power, its production capacity per hour is twice as much as other jet mill, mixing grinder and ball mill.
2. Long lifecycle of wearing parts
The ring and rollers are forged by special material with high utilization. Under same grinding material and finish fineness, the wearing parts life cycle usually is one year, which is 2-3 times longer than impact mill and turbo mill. The service time can reach 2-5 years if grinding carbonate (calcium carbonate).
3. High safety and reliability
There are no rolling bearings and bolts in grinding cavity, so there are no problems caused by bolts shedding or wear of bearings and seal components.
4. High fineness and flexible adjustment
The final product fineness can be adjusted between 325 meshes and 2500 meshes (47 microns to 5 microns), and the product fineness can reach D97≤5μm.
5. Environment friendly
The application of pulse deduster and muffler alleviate the dust pollution and noise.
