Like most heavy machinery, stone crushers can be hazardous to work with. It is therefore important that crusher operators and other employees in related operations take the necessary precautions to avoid accidents and injuries from happening. Only employees familiar with the machinery and stone crushing operations should be allowed to work in the proximity of stone crushers or operate them. What is the Process Involved With Operating a Stone Crusher? The task of a stone crusher operator is one of monitoring and overseeing rather than physically driving the machine. In general, the stone crusher forms part of a production line where each step is generally automated. For example, the rock will be fed into the stone crusher via a conveyor belt or heavy duty feeder. Often, the feeder has a vibrating mechanism that sifts out the small pieces of rock that don't need to be crushed. The purpose of this is to improve the efficiency of the crusher so that it is not processing rock that does not need to be crushed. Once the rock feeds into the crusher, it is gradually crushed until it is small enough to fall out of the bottom of the crusher. Typically, the rock will be caught on a vibrating screen where once again the smaller pieces get sifted out of the process. The rock with either then enter a secondary crusher or go through a process of washing and sorting so that it can be used for other industrial applications. There will be various channels in the processing system. Some deal with raw materials, other waste products and others still the finished materials. Any blockage or malfunction in the system will affect the whole workflow process. Therefore, knowing the optimum level at which all the systems should function is important for the staff operating the various machines. What are Some Potential Hazards When Working With Stone Crushers? From the start of operations, there is any number of situations that could prove to be hazardous. For example, someone could slip on oil or liquid that was spilled onto the floor during routine maintenance. Rocks could fall out of the feeder and damage nearby machinery or injure employees. There could be undetonated explosives lodged in the rock ore. The feeder could be operating at the wrong velocity, feeding too much rock into the crusher and causing it to jam. People inspecting the crusher could drop objects into the crusher. Their safety gear or harness could be faulty and they could fall into the crusher. Even if the crusher is offline at the time of the accident, recovering the person out and attending to their injuries could be potentially hazardous. Precautions to Ensure Safe Crusher Operations The crushing machinery needs to be regularly and properly inspected for any wear and tear. This includes checking that fittings, bolts and nuts are securely fixed, that the crusher linings do not have any cracks in them, and that oil and hydraulic lines are not pinched or leaking. A small thing like a loose bolt can have a catastrophic effect on operations. It could result in parts of the crushing machine bending or breaking as the bolt works loose. Material could be spilled, people could be injured and the expense of having to repair and restore the machine to working order could be huge. Feeding and processing rates need to be constantly monitored. Mined rocks are generally very uneven in shape and size and it's not unusual for blockages to occur. Generally, a processing plant with have very specific steps for dealing with such scenarios so that no damage is caused to the machinery and no injuries occur. When operating a stone crusher, the right safety equipment needs to be worn. This may include hard hats, safety goggles, ear muffs, industrial gloves and shoes, overalls and reflective gear. Training and Safety Procedures Many accidents and injuries can be avoided if employees are properly trained in operations and safety procedures. Using preventative measures is always more efficient than trying to solve a problem situation after it has occurred. It's therefore very important that any new employees go through a thorough orientation and training program before they take up their positions in the processing plant. It's also vital to have regular safety drills and refresher courses from time to time with existing employees. Stone crusher operators need to be vigilant in their checks each time they come on shift. Safety procedures can sometimes seem tedious but following them can prevent accidents and injuries. This is something that needs to be drilled into employees on every level of the organization.
