Pair (Double) Roll Crusher product description
Pair (double) roll crusher is suitable for medium and fine crushing
of solid materials with compressive strength less than 250Mpa and
moisture less than 35%, such as crushing iron ore, quartzite,
potassium (sodium) feldspar, limestone, river pebbles, silicon
metal, barite, basalt, granite, steel slag, cement clinker,
construction waste (concrete), shale, quicklime, coal, coke, clay,
bentonite, chemical raw materials, etc. It can be widely used in
mining, thermoelectricity, cement ceramics, metallurgy, chemical,
building materials and other industries. It can be widely used in
mining, thermoelectricity, cement ceramics, metallurgy, chemical
industry, building materials and other industries, and is
characterized by low maintenance cost, low water requirement,
reliable performance, low power consumption, low dust, low noise
and so on. Counter (double) roll crusher is
equipped with two crushing rolls, according to the granularity
required by the user, the roll surface is divided into two forms:
flat roll surface and surfaced roll surface, flat roll surface
model is suitable for fine crushing operation with feed size less
than 80mm and finished product size 1-10mm. Surfacing roller models
are suitable for feeding size less than 60mm, the finished product
size of 5-30mm fine crushing operations.
If the compressive strength of the
material more than 250Mpa are recommended to choose energy-saving
roller (mill) machine, according to user requirements are divided
into belt and coupling drive (hard link) two ways, the equipment in
the mine without electricity can be changed to diesel or gasoline
engine as a power.
Pair (Double) Roll Crusher working principle
Pair (double) roll crusher is the use of
two high-strength wear-resistant alloy crushing rolls, the relative
rotation of the high extrusion pressure to break the material, the
material enters the gap between the two rolls (V-shape crushing
chamber), by the relative rotation of the two crushing rolls of the
extrusion and shear force, in the extrusion, shear and grinding,
the material will be crushed into the required size from the
discharge port discharge.Pair (Double) Roll Crusher Technical Parameters
