NTB-4 VACUUM EXTRUDER
DESCRIPTION
A perfect equipment for those who need a quality extruded material, it produces up to 20 Ton/hour of ceramic products such as bricks, structural blocks, slab covers, cast elements, sticks for tiles, tiles and other products. Its function is to remove air from the clay by the vacuum system, compress and model the product and to prepare for press or cutter. The NTB-4 Vacuum Extruder differs from other machines of this size by having high hardness grinding gears and compact shafts, which allows for the extrusion of harder clays, greater production and reduction of energy consumption. The result is a product of perfect finish, with excelente mechanical resistance and low tensile index.
CONSTRUCTIVE FEATURES / DETAILS
- Helicoidal gears some of which are thermally treated and rectified, which guarantees reduced transmission friction and high durability.
- Wide and reinforced vacuum chamber through which air is extracted from the clay that arrives in the coil, and where the axial bearing that supports the extrusion effort is mounted.
- Hammers with replaceable edges, easy to replace.
- Excellent polishing coil, reduces clay adhesion and consequently increasing yield and production stability.
- Bipartite cannon with plate coating and directing splints
- Welded and heat-treated steel sheet housing relieves stresses and prevents cracking.
- Simple and smooth drive electro-pneumatic clutch that prevents violent torsional stresses on the shaft.
- Forced lubrication by gear pump
- Radial spherical roller thrust bearings and thrust bearing (thrust).
- Fully coated wear body.
