The crushing equipment is used for a variety of applications and it plays a key role in the mining and construction industry. For safe and efficient crushing procedure, you need to have the right crushing equipment. With so many crushing machines on the market, choosing the right crushing equipment for your job can be a difficult task. Having the right crusher will have a direct impact on the quality of the final product. The two most commonly used crushers are the primary impact crushers and the heavy-duty jaw crushers. Before making any final decision, consider the characteristics of these two crushing machines:
Primary Impact Crusher – A primary impact crusher is generally used for crushing materials of grain size and for recycling concrete and quarried stone. Most impact crushers are secondary crushers, but there are primary impact crushers as well. With higher reduction ratio than the jaw crushers and with dependable crushing performance, the primary impact crusher is capable to crush even the hardest materials. This crusher is composed of a rigid and durable rotor, over-sized bearings, a hydraulic mono-block feed plate, a large feed opening, and hydraulic cylinders that provide continual crushing force.
The working principle of the primary impact crusher is almost the same as the usual impact crusher. It uses an impact force to crush materials in a crushing chamber, and the material goes out of the crusher once it has the desired size.
Heavy-Duty Jaw Crusher – The heavy-duty jaw crusher is specifically designed for dealing with the toughest materials in the toughest crushing environments. For maximized performance, the heavy-duty jaw crusher comes with a large crushing chamber that provides high-volume crushing even with hard materials. Also, the heavy-duty jaw crusher is easy to use and easy to maintain, since it is composed of the most durable parts that can be found. For daily operation and low cost crushing performance, the heavy-duty jaw crusher is the most obvious choice.
The heavy-duty jaw crushers come with simple parts that can be easily repaired or replaced. They are composed of a replaceable impact plate which protects the barrel, mainframe protective liner, lock-out pin that increases the safety, and wide bearings that allow longer service life. With all these parts, the maintenance of jaw crushers is very convenient and easy.
