<strong>Job</strong> <strong>Report</strong><br />
Description of the <strong>Plant</strong><br />
HAZEMAG has delivered an exceptionally powerful impact crusher <strong>for</strong> limestone crushing to<br />
the <strong>Obajana</strong> <strong>Cement</strong> Works in Nigeria. The cement works belongs to the renowned Dangote<br />
Group, one of the largest cement producers in Africa.<br />
Every hour this large impact crusher breaks up <strong>2000</strong> t of limestone with feed sizes that have<br />
a maximum edge length of 1.5 m to a degree of fineness of 98% < 75 mm. For this task the<br />
heavy GSK cast-iron rotor has a diameter of 2.5 m and a width of 3.0 m. Its weight is<br />
54,000 kg, while that of an individual blow bar is 1,550 kg. The impact aprons are controlled<br />
with the well-proven HAZEMAG hydraulic system. In spite of the enormous weights of these<br />
components, it is possible with this system to precisely adjust the gap width between the rotor<br />
and impact aprons at the press of a button. However, the hydraulic system is also active during<br />
the crushing process and holds the impact aprons permanently in position. If <strong>for</strong>eign materials<br />
that cannot be crushed enter the machine, the impact aprons draw aside and allow the <strong>for</strong>eign<br />
materials to pass by. They then return to the starting position. The crusher there<strong>for</strong>e has a high<br />
level of operational reliability and guarantees a consistent product quality.<br />
The raw material is fed to the crusher by means of a heavy HAZEMAG apron feeder with variable<br />
drive. This also has exceptional dimensions due to its width of 2.5 m and length of 14.2 m.<br />
