The movable jaw plate approaches the fixed jaw plate periodically to realize the functions of crushing, splitting, breaking, and impacting, thus to coarsely or mediumly crush materials with various hardness. It was invented by American E.W. Black in the 1850s. The specification of jaw crusher is expressed by the feed port width B and The double jaw crusher is designed for crushing hard materials, also quarried materials, sand and gravel, and recycling.

Crushing efficiency can be calculated using the following formula: Crushing Efficiency = (Output (TPH) / Input (HP)) * 100. This crushing efficiency formula is an effective tool for understanding what is crushing efficiency and how to calculate it. Here, TPH represents the tons per hour of the material that is outputted from the crusher, and HPThe power required to deliver the through put efficiency of the machine was determined to be 5,480W. The rotor speed is obtained as 1289.1 rpm. Table 2.1 Feed Figure 2.2 A typical Jaw(PDF) DEVELOPMENT OF A HORIZONTAL SHAFT HAMMER MILL CHAPTER

Where T is throughput of jaw crusher (ton/hr); P 80 is 80 % passing size of feed (mm). So as well as the relationship between P 50 and the throughput of the jaw crusher, this empirical equation can also be used to give a throughput prediction of a similar jaw crusher. A practical prediction table for certain P 80 values is given in Table 6Mechanical Crushing and Grinding. Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009 Crushers. Crushers are widely used as a primary stage to produce the particulate product finer than about 50–100 mm in size.

Feed size of the jaw crusher is 1500mm-40mm and the product size is from 50mm-5mm. Rpm for jaw crusher is between 200-400. Jaw crushers are heavy duty machines and hence need to be robustly constructed. The outer frame is generally made of cast iron or steel. The jaws themselves are usually constructed from cast steel. Learn MoreC Series™ jaw crusher basic concepts The jaw crusher is a compression type crusher. Feed material is crushed between fixed and movable jaw dies. Large particles are crushed in a single layer, referred to as single-layer crushing. Smaller particles are crushed rock on rock, referred to as multi-layer crushing.

As excessive wear can cause a 10–20% reduction in production, it is important to find the optimal time for the jaw turn or change in terms of cost and benefit. Again, with the same scenario with C130, we would have approximately a 70 stph reduction in production, inHow to improve jaw crusher performance and productivity

The coarse aggregates obtained by different crushing mechanisms (jaw and impact crushers) show very similar characteristics in terms of binder content assessed by acid leaching (27.5 and 26.6 wt.%), water absorption (8.76 and 9.75 wt.%) and porosity (18.6 and 20.2 vol.%).Thus, it is not possible to conclude that any of these mechanisms The main reason for this inefficiency is in the random distribution of forces on the particles inside the crusher. With certain simplifications, the theoretical energy efficiency of comminution can be estimated to fall between 5 and 10 % (Legendre & Zevenhoven, 2014) while the measured energy efficiency in actual comminution testing Assessing the energy efficiency of a jaw crusher ScienceDirect
