Crushers

Sands and Sandstones - Sands are loose, unconsolidated rocks having particle sizes between those of silt and pebbles (1/16 mm to 12mm).   When held together by chemical cement or by clay, they are called sand- stones. These rocks result from the breaking down or weathering of older rocks, and from the transportation and sorting of the rock fragments by moving water or by wind.

 Compaction - Soil compaction may be defined as the process of increasing the density of a soil by (1 ) expelling air from the pores, (2) decreasing thickness of water films thereby increasing cohesion, and (3) increasing mechanical bond, or interlocking, of soil particles. This is accomplished by vibratory rolling, static rolling, static loading, and tamping.

 Asphalt Rock – Asphalt is a solid or nearly solid organic substance composed of carbon and hydrogen, which is formed when the lighter parts of petroleum evaporate and the heavy tarry residue remains behind. Natural asphalt, that is made by nature and not in an oil refinery, is found in the pores of some limestone and sandstone. It occurs in rocks of the Pennsylvanian Age and in small amounts in cretaceous sandstone.

 Artificial Sands are commonly called crusher screening, they are the fine materials produced when gravel or stone is crushed. These screenings vary considerably as to angularity and gradation, depending upon the type of rock crushed, but fairly well-graded sands can be produced in this way.

Nordbak high temperature grout is a 100% solid epoxy grout system formulated to withstand temperatures of up to 250°F. This unique grout is stronger than concrete and will adhere where other grout fail.

Nordbak high temperature grout offers the following superior characteristics:

 Nordbak fast-set grout is a unique 100% solids epoxy grouting system that reduces maintenance costs sharply. It mixes quickly, and can be applied by just two men, without mixers, wheelbarrows or special equipment.

 USE Nordbak Epoxy Resin WHEREVER HIGH WEAR RETARDS PRODUCTION AND BOOSTS COSTS:

 This advanced material for armor surfacing all areas where solids or slurries cause abrasion is a unique composite of Nordbak Epoxy Resin, sapphire hard alumina ceramic beads, and silicon carbide. The beads take the abrasive wear. They are held securely in suspension, and to the surface to be treated, by the Epoxy Resin.

The trowelable material is easy to mix and apply on any surface and will conform to any shape such as cones, elbows, and other curved surfaces. Nordbak Wearing Compound cures fast and will have previously worn surfaces back in service quickly.

 Nordbak Backing Material, when used as a mill liner backing material, will prevent shell erosion due to slurry or pulp racing, liner breakage because of non-uniform fit of the liner castings on the shell, and the loosening and shifting of liners during operation. It is being used successfully to back Nordite and Chrome-moly Castings in rod and ball mills used in the mining industry and raw and finish mills in the cement industry.

 Nordbak Locking Compound

Locking Compound is a high temperature and high impact material for locking inner and outer eccentric bushings in Symons cone crushers. It is safe and easy to use. You save time and money with Locking Compound because all you do is mix and pour at room temperatures. No special training or experience is required.

 NORDBAK BACKING MATERIAL

A 100% Solids Epoxy System. Nordbak Backing Material is the Easy, Safe and Positive way to back wear metal is all types of crushers and grinding mills.
