Bauxite is a sedimentary rock, consisting of a mixture of aluminum minerals (Bohm, diasporas, Gibbs), iron (goethite, hematite) and clay minerals (kaolinite).

Conveyor belts and accessories
Conveyor belts are used for transport bulk and solid materials in various industries. Conveyor belts can be usefull mainly in these areas:
Steel-Cord Conveyor Belts
These conveyor belts are being used mainly to transport materials in long axle distances in difficult working conditions. This is possible because of their small elongation while loading and great ability to adjust to a conveyer’s trough thanks to its low cross strength. The carcass of the belt consists of extremely strong steel cords stored in one level, covered with adhesive rubber to perfectly connect top and bottom cover layer. A strong connection between layers ensures optimal functionality and high resistance. Cord pitch and the strength of the cords are used to specify strength series.
Rubber-Textile Conveyor Belts
These conveyor belts are for general usage. They are mainly used to transport loose and general material in standard conditions. The carcass of the belt consists of 2 – 6 textile plies made of combined polyester (E) and polyamide (P) fibre. These are known for their great strength and fantastic physical and mechanical features. They are made with either cut or protected edge, with a strength range between 200 – 3 500 N/mm and a width of 400 – 2 400 mm (chart in PDF format). Cover layers assure conveyor belt is contacted to transported material, rollers and drums exactly. That is why it is important to pay maximum attention to choosing the right thickness and category of cover layers.
PVC/PU Conveyor Belts
All of them have an individual character according to layers, profile, thickness and hardness of the surface, according to a high adhesion in sloping belts up to easier emptying material from the belt. Belts with surface layer of 1 mm and more can be covered with PVC, PU with variable hardness before profiling.
Profile Conveyor Belts
Unlike conveyor belts with an even profile, they enable transporting material with an angle above 30°. Profiles on the conveyor belt hinder material landfall and increase the volume of transportation. They are made with various types of profiles according to customers needs, connected or not connected, with width of 400 – 1 200 mm.
