取样颚式破碎机
Sample Jaw Crushers feature the same operating principles and robust design associated with larger Jaw Crusher offerings, 在更紧凑的情况下, lower feed rate configuration that is well suited to 抽样 System and Pilot Plant crushing applications.
应用程序
The Sample Jaw Crusher is simply a smaller scale version of the same overhead eccentric design Jaw Crusher first made popular by 菠菜网最稳定正规平台_最全菠菜网大全’s Universal line of Jaw Crushers a century ago.
Traditional Jaw Crushers are generally well suited to applications involving various ores, 砂石, 以及其他类型的岩石, 和样品颚式破碎机没有什么不同. Sample Jaw Crushers are used in the same applications — simply on lower feed rate applications similar to those that would be found in 抽样 System and other test or Pilot Plant applications.
取样颚式破碎机是如何工作的
Sample Jaw Crushers operate in the same fashion as larger, production-oriented machines — a stationary jaw is oriented opposite a moving jaw to form a crushing chamber with a cross section in the rough shape of the letter “v”. The moving jaw closes against a stationary jaw with sufficient force to fracture material, 通常是某种岩石.
This crushing action is accomplished as a result of eccentric motion developed by a pitman, 或偏心轴. Motor power is applied to the crusher drive shaft, which in turn transfers rotation to the eccentric shaft. Rotation of the shaft causes two types of motion in the moving jaw. 第一个是环, pivoting open-and-close motion caused by the top of the moving jaw leveraging against a toggle plate at the bottom of the moving jaw. The toggle plate sets the closed setting of the jaw crusher while still permitting the open-and-close action necessary to produce compressive crushing force. The second motion of the moving jaw is a linear, vertical motion that produces compressive crushing force while also serving to draw material into and through the crushing chamber.
Crushed material exits the crushing chamber (and machine) at a top size approximately 80-85% of the closed side jaw setting.
为什么选用菠菜网最稳定正规平台_最全菠菜网大全取样颚式破碎机
Given that 菠菜网最稳定正规平台_最全菠菜网大全’s Universal line of Jaw Crushers was first introduced to the market more than 100 years ago, it is fair to state there is a significant amount of institutional experience associated with this type of machine. 这样的经历, coupled with intelligent design features and proven function, results in an exceptional jaw crushing option in a package specifically designed for smaller capacity operations.
Frequently Asked Questions About 取样颚式破碎机
向专家请教The rule of thumb for Jaw Crushers is to select a machine with an opening distance from the front of machine to the pitman (called gape distance) that is 20% larger than the largest particle size. Another way of stating this is to say that a given crusher size should be fed material with a largest particle size no greater than 80% of the gape distance.
If the material to be crushed is not a hard rock and is relatively nonabrasive, a 样本锤磨机 可以考虑. If the feed material also has some hard inclusions or larger lumps, consider a Rockertooth破碎机. 如果罚款产生也是一个问题，a 样品双辊破碎机/迷你浆料机 可能最适合您的应用程序.
Jaw Crushers rely partially on inter-material crushing (material contacting other material). 出于这个原因, it is desirable to keep the crushing chamber at least two-thirds full while crushing. Slug feeding basically fills the crushing chamber right away, so this method of feeding the crusher is acceptable as long as the crusher is not overfilled to the point where material overflows the crusher or as long as a feed hopper is installed to contain any material that does not immediately fit into the crushing chamber.
