Technical graphite for seed drills is a powder of dark gray color with metallic shine, intended for filling into seed drill hoppers together with seeds. It is used to prevent the seed from sticking to the walls and the seeds from sticking together.

What is technical graphite

Graphite is a common natural mineral, an allotropic modification of carbon with a layered structure. Graphite crystals are flaky, lamellar. Graphite conducts electricity well, is characterized by softness, its density is from 2.08 to 2.23 g/cm. cube. It is a hard-melting substance, resistant to heat, does not dissolve in acids, to the touch is greasy. Natural graphite contains no more than 12% of impurities, which are completely harmless to the environment. Graphite is used in the manufacture of pencils, electrical rods and electric brushes for motors, it has become indispensable for seeding work.

Advantages of using graphite for seed drills

Technical graphite for seeders has found wide application in various industries. Graphite powder is no less in demand in agriculture.
Due to its unique properties technical graphite:● Increases the efficiency of seeding operations;● Extends the service life of seeders;● Improves the bulkiness of the seed;● Serves for lubrication of seed drill units and assemblies;● Prevents seed damage;● Reduces seed sticking;● Prevents seeds from sticking to the walls of hoppers;● Creates an antistatic effect;● Has water-repellent properties.
Fraction size of technical graphite for seeders does not exceed 20 microns. Graphite powder is environmentally friendly, does not contain harmful impurities, does not deteriorate soil properties. The optimum amount of graphite is determined experimentally in the process of work. The rate of consumption depends on the method of seed pre-treatment, weather conditions, type of seeder and other factors. The average rate is 1.5 g per 1 kg of seeds, if they are treated with fungicides or insecticides - 3 g. If the planter is installed metering with finger picker - 0.75 g. Graphite for seeders technical graphite is packed in bags and buckets of different capacities.
Technical graphite is widely used in the work of row seeders and precision seeders to increase the service life of seeding equipment, prevent damage and sticking of seed material. Graphite powder is recommended for use in pneumatic seeders John Deere, Lemken, Kinze, Monosem, Great Plains, Kverneland and others.
