3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm.

In conclusion, spiral foraging offers a unique and sustainable approach to gathering wild edibles. By combining ecological understanding with a systematic method of exploration, foragers can cultivate a deeper appreciation for nature while minimizing their impact on the environment. This technique not only enhances the foraging experience but also promotes responsible practices that benefit both the gatherers and the ecosystems they inhabit. As we continue to seek sustainable food sources, methods like spiral foraging serve as valuable reminders of our interconnected relationship with the natural world.

In the mining sector, jaw crushers are extensively utilized for the primary reduction of various materials. These include limestone, granite, and ore, all of which are naturally tough and abrasive. The effectiveness of jaw plates made from manganese steel directly impacts the efficiency of the crushing process. A well-designed jaw plate can significantly reduce downtime caused by wear and tear, leading to increased productivity and lower operating costs for mining companies.

  • Due to the machine's working environment being prone to intense vibrations and impacts, constantly observe the dynamics of various parts during operation. If you detect abnormal noise or other irregularities, shut down the machine immediately for inspection and repair before resuming operation. If hydraulic system connectors leak or components become loose, shut down the machine for adjustment and tightening. After ensuring everything is normal, you can resume operation. Before completing each shift, lower the hydraulic hammer to the lowest position and retract all other hydraulic cylinders to their shortest length. If moving a distance, keep the mast leaning backward. For the machine's components, accessories, and electrical equipment, perform regular inspections, especially the connections in the wiring of the motor. During operation, there should be designated personnel for guidance. The guide and the operator should check signals with each other before work and cooperate closely. At the start, use a bell or other methods to signal and inform surrounding personnel to move away. The machine should start at a low speed and gradually accelerate to high speed.
