نظرة عامة على المشروع:
Graphite and carbon materials boast outstanding properties and find extensive use across industries, experiencing rapid growth in productivity and efficiency. In recent years, the Chinese graphite and carbon sector has expanded significantly, with improved management and profitability. Data from national statistics indicate that in 2011, the industry achieved remarkable increases in output value and profits, reflecting intensified competition driven by broader applications.

وصف المادة:
Graphite is a crystalline carbon allotrope with a hexagonal structure, exhibiting a dark gray color similar to iron ink. It has a density of 2.25 g/cm³, hardness of 1.5, melting point at 3652°C, and boiling point at 4827°C. It is soft to the touch, electrically conductive, chemically stable, and resistant to acids and alkalis. When heated in air, graphite oxidizes to carbon dioxide. Its applications include lubricants, crucibles, electrodes, batteries, pencil leads, and as a neutron moderator in nuclear reactors.

Equipment Overview:
The graphite rotary flash dryer is a product of extensive R&D and multiple iterative improvements, featuring advanced technology, robust construction, and elegant design. It is widely used in pesticides, paints, dyes, pharmaceuticals, feed, fertilizers, and fine chemicals. The equipment provides efficient, rapid, energy-saving drying suitable for both small and large-scale production while minimizing pollution. Leveraging advanced design tools and experienced engineering, customized solutions ensure optimal operation aligned with material properties and plant layouts.

مبدأ العمل:
Clean air is heated via a heat exchanger and introduced tangentially into the drying chamber, creating a spiral airflow. Material is fed continuously into the chamber by a variable-speed screw feeder. Inside, hot air fully interacts with the material, promoting efficient heat and mass transfer. A volute air distributor and adjustable high-speed agitator maintain a stable fluidized bed, preventing clogging and continuously crushing the material to expose fresh surfaces for effective drying. The drying chamber is jacketed with cooling for heat-sensitive materials to maintain product quality. Particles are classified mid-chamber by centrifugal forces; oversized or insufficiently dried granules are returned for further drying, while fine dried particles are collected and conveyed for packaging. Exhaust gases pass through dust removal systems before release.

سمات:

1. Pyramidal drying chamber base ensures stratified gas velocities, keeping large particles fluidized below and finer particles above, enhancing drying uniformity and equipment reliability.

2. Specially designed stirring blades continuously crush and scrape material from the chamber walls, preventing build-up and ensuring smooth operation.

3. The top grading ring separates larger particles for reprocessing, maintaining tight particle size distribution and moisture uniformity.

4. Cooling jacket at hot air inlet zone prevents material deterioration due to localized overheating, protecting product quality.
