Manufactured Cubic gravel production

At present, the quality of coatings constructed roads increased demands on the strength characteristics as well as the shape and size of fillers. Increase in the intensity and speed of vehicles makes a loud voice to talk about safety, one of the components of which - the high quality of the pavement.

Our company SBM offers unique equipment and technology to produce cubic shaped manufactured gravel that meets all modern standards and requirements.

The use of cube-shaped manufactured Cubic gravel provides a smooth texture coating, which reduces noise and increases the surface roughness. Cubic shape stone provides them a snug fit for each other, increases the wear resistance and durability of the coating. The method of active strike a stone on a stone grinder used in the centrifugal shock, stone crushes the rock along the lines of natural fractures, which increases the strength of the pavement, not only by reducing the flakiness, but also by reducing the fracture cube of manufactured cubic gravel.

The basis of production lines to produce cube-shaped manufactured cubic gravel is the use of centrifugal impact crusher VSI5X the last stage of division (depending on the technology, working in an open or closed loop). Upon receipt of rubble on vertical shaft impact crusher is a radical improvement VSI5X shape and mechanical properties of the grain. Flakiness received rubble of an absolute majority of minerals is 2-10%, which fully covers the the world standard.

The vertical impact crusher for manufactured cubic gravel production

A special place among the equipment to get the cube-shaped manufactured cubic gravel is produced by the "SBM" centrifugal impact crusher VSI5X. It is intended for processing solid igneous rocks with a compressive strength of 300 MPa, however, can be used in the processing of hard sedimentary materials. The design of the centrifugal impact crusher VSI5X similar to the construction of vertical roller mills VSI, but there are significant differences.

By reducing the amount of chipping to stoves increased the size of a crusher and reduced the number of collisions between the pieces of material. By reducing the linear velocity of the top of the beat reached the optimum combination of strength and strikes. All this is only possible to achieve crushing flakiness grains, as the weaker, and the cube-shaped grains remain intact.

Crushing screening plant on the basis of centrifugal impact crusher capable VSI5X if configured to produce narrow fractions of stone rocks in increments of 5 mm, and also to save the company from illiquid products due to the minimum number of screenings (waste fractions 0-2 m).

Manufactured cubic gravel production provision

Opencast line with the vertical shaft impact crusher VSI5X provide:

Receipt of rubble containing cube-shaped grains of at least 90% of all the factions, the ratio of the thickness of the grain to its length at over 80% of the grains does not exceed 1:2, whereas the cube-shaped (not flakiness) grains are grains of GOST with a ratio of 1: 3 or less;
Increase the strength of crushed gravel at one stage, reducing the fracture fragments and the fraction of particles with a weakened form: the strength of gravel (in terms of divisibility), resulting in a centrifugal impact crusher VSI5X, increases from 16 to 29%;
Receipt of rubble rock solid with dust <1.0%
Receiving screening form with isometric grinding grain.

With stricter requirements as to safety and quality of our products, we should expect the expansion of the range of concrete, concrete products and asphalt pavement, requiring the use of cube-shaped rubble I group.
