(1) According to the thickness of the ore body and the single design requirements of the ore body, the electric roadway can be arranged along the strike or cut direction. (2) The electric ramp should meet the following requirements: 1) In order to fully release the ore of the last funnel, the electric ramp should exceed the last funnel, and its length is not less than 5.5 to 6.0 meters. 2) Considering the convenience of operating the electric power and the influence of the electric winch on the secondary crushing, the length of the winch chamber is generally 4.0 to 5.5 meters. The safety distance from the side of the mine to the winch is 2-3 meters. 3) The junction of the electric ramp and the mine discharge shaft should be appropriately widened to ensure the safety of pedestrians. 4) When two or more electric rafts are arranged, the center distance is 10-15 meters. (The red-transparent mountain mine actually uses 15 to 17 meters). 5) The electric rafts are generally arranged horizontally, but they are also arranged along the slope, and the inclination angle should not be greater than 25 ° ~ 30 °, the slope of the ramp is high efficiency, but when handling card leakage and secondary crushing, the safety is poor. 6) The slipway can not be dug in a certain funnel, and must be staggered by a certain distance (4 meters in the book, the key to see the natural angle of the ore of the ore, generally must be more than 2 meters.) Otherwise, the processing of bulk and card leakage It is very difficult. 7) There are two ventilation pedestrian safety exits in the electric roadway, which cannot be designed as a single-head electric roadway. 8) The floor of the winch chamber should be lower than the level of the other side of the chute (0.3 to 0.3 m), which is beneficial to the antimony ore. Mini Fiber Laser Cutting Machine
The Fiber Laser Cutting Machine is a full-enclosed small fiber laser cutting machine with high precision, suitable for cutting small precision parts. The whole fiber laser cutting machine adopts the new three-dimensional protective cover and the pull-out table to protect the user's body and make the work more efficient and safe. The fiber laser cutting machine can be used in the home, it is the preferred choice for home workers and high-precision device processing.
1. The fiber laser cutting machine adopts all-inclusive design to prevent laser radiation from causing harm to human body. It is safe and environmentally friendly, in line with international safety protection standards. Using large visible laser protection safety window, can better observe the operation of the machine.
2. Machine bed of fiber laser cutting machine is welded with 12-16mm thick carbon structural steel dislocation honeycomb structure, machined after stress relief and annealing, then vibration-aging and natural aging treatment, so that the welding and machining stress can be completely eliminated, to ensure excellent rigidity and high precision of the bed, reducing the machining error caused by the vibration of the bed.
3. Laser protection devices of fiber laser cutting machine are installed on both sides of the door, so that the door in the process of falling, if the human body strayed will immediately stop falling, while the alarm light on, thus solving the safety problem of the user.
4. The working platform combined with pull-out slide and roller is easy to operate, safe and reliable, ergonomic, convenient for feeding, and the cylinder locks the back bed to ensure safe operation and cutting precision of the fiber laser cutting machine.
