China Single Roll Crusher for Sinter Slag Shale Limestone, Find details about China Mine Crusher, Crushing Machine from Single Roll Crusher for Sinter Slag Shale Limestone
Brief introduction
Single-roll crusher is applied for crushing of fragile and low/medium-hardness material,
such as sinter, slag, shale, limestone and etc. Single roll crusher integrates jaw crusher
and roll crusher together, thus has characteristics of the two types of crushers.
Mode of operation
One rotating toothed roll and a set of grate bars constitute broken mechanism of
single-roll crusher. Crushing roll is driven by emotor through reducer. Material lumps
enter between crushing roll and grate bars via charging plates, and then crushed with
squeezing and breaking by toothed roll and grate bars. To enhance stability and
wear-resistance at high temperature, water cycling system is equipped to cool
crushing roll shaft, crushing teeth and grate bars.
Structure Characteristics
-Drive Mode
. . E-motor drives tooth roll through safety coupling/fluid coupling and big reduction ratio
gear box;
. . E-motor drives tooth roll through safety coupling, small reduction ratio gear box and
open gear set.
-Fixed Base Frame/Mobile Trolley
Grates are placed on base frame, and crushing roll and base frame are fixed on concrete base.
Structure is compact and it is easy to install.Bearing brackets of crushing roll are fixed on the
foundation, and grates are placed in the trolley, under which there are wheels and rails.
While working, trolley is fixed firmly on the base. When repairing grates, trolley can be
moved down to paved rails and pulled out by winch unit for maintenance.PSB alloy bearing
shell or roller ball bearing is adopted to meet requirement of poor working conditions,
heavy load, low speed. Bearing box is split type.
-Crushing Roll
Star wheels and main shaft of crushing roll are made separately. Star wheels and main
shaft are of inside and outer hexagonal design for easy replacement. Main shaft is drilled
with through-hole for cooling with circulating water. There are two types of crushing
teeth:
. . Made of heat-resistance & wear-resistance alloy steel, and mounted on star wheels;
. . Cast with star wheel as a whole with crushing section hard faced with heat &
wear-resistance welding wire, and its lifetime is more than 10 months.
-Grate
. . Grate is fitted liner, which is made of heat & wear-resistance alloy steel;
. . Surface of grate is hard faced with heat & wear-resistance welding wire.
