  • Page 166: Scope Of Works Using Mobile Crusher

    OPERATION OPERATION SCOPE OF WORKS USING MOBILE CRUSHER WARNING When crushing natural rock, do not feed the crusher with pieces of rock that are larger than the maximum feed dimension. This will not only reduce the crushing capacity and lower the production, but may also cause pieces of rock to fly out. In addition, it will create overload in the crushing operation, and there is danger that this will damage the crusher.
  • Page 167 OPERATION OPERATION CAUTION When crushing natural rock, do not feed the crusher with lumps of rock larger than the maximum dimension for rubble feed. The crusher will not be able to grip the lumps easily and this will lead to a drop in production. In addition, there is danger that the rock will fly up and out.
  • Page 168 OPERATION OPERATION KEEPING SOME HEIGHT UNDER CRUSHER When crushing reinforced concrete debris, it is advisable to increase the clearance between the crusher underside and the belt conveyor top to ensure good discharge of the debris. If many long reinforcing bars are contained in the reinforced concrete debris to be crushed, adjust the posture of the primary belt conveyor in the following manner prior to the start of work.
  • Page 169 OPERATION OPERATION REMOVING REINFORCING BARS FROM CONCRETE BLOCKS WARNING When you have to get in the crusher chamber for removing reinforcing bars , be sure to stop the engine first, then hang a warning tag to the starting switch in the main control box and start the work. NOTICE When crushing reinforced concrete debris, they may remain around the jaw crusher outlet or on the belt conveyor.
  • Page 170 OPERATION OPERATION 3. Enter the machine from the side of the engine frame and remove the accumulated steel rods. 4. After all the reinforcing bars have been removed, attach the earth spillage preventive rubber plates that were detached in Item 2 above. NOTICE Be sure to push in the rubber part of the earth spillage preventive plates on to the primary conveyor frame surface after attaching them to the machine.
  • Page 171 OPERATION OPERATION REMARK If the steel rods are caught inside the conveyor and cannot be removed, run the conveyor in the reverse direction to reduce the pressure and make them easier to remove. CAUTION If inching is used continuously in the reverse operation, the soil on top of the conveyor will be carried back and accumulate, and this may damage the equipment.
  • Page 172 OPERATION OPERATION CRUSHING NATURAL ROCKS NOTICE If natural rock with large amounts of moisture (soil, mud, etc.) stuck to it is crushed, it may cause clogging of the grizzly feeder and premature wear of the fixed jaw plate, movable teeth, and packing at the discharge port of the crushing chamber of the jaw crusher, so use a skeleton bucket for the loading operation.
  • Page 173 OPERATION OPERATION CRUSHING ASPHALT CONCRETE DEBRIS The mobile crusher can crush asphalt concrete debris produced in a road construction site. NOTICE Asphalt concrete rubble has high viscosity, so be careful of the following points when carrying out the operation. If discharge port clearance (A) is set to less than 80 mm (3.2 in) (OSS), packing will occur more easily at discharge port (B) of the crushing chamber of the jaw crusher, so use with the discharge port clearance (A) of the jaw crusher within a range of 80 to 150 mm (3.2 to 5.9 in) (OSS).
