Assessing the energy efficiency of a jaw crusher

Jaw crusher A jaw crusher uses compressive force for breaking of particle. This mechanical other reciprocates. A jaw or toggle crusher consists of a set of vertical jaws, one jaw is ke pt stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a Different possibilities to define energy efficiency 1. Specific energy of mill compared to new created surface energy not meaningful, efficiency much smaller that 1% 2. Specific energy of mill compared to minimum specific energy requirement in so-called element tests. However, here at least two possibilities exist a. breakage energy of single particle stressing by compression / by impact

Energy Policy Act of 2005, which established a number of energy and water management goals for Federal facilities and leets and also amended portions of the National Energy Conservation Policy Act (NECPA). Executive Order 13423, Strengthening Federal Environmental, Energy, and achieve the desired size reduction. Gyratory crushers, jaw crushers, roll crushers, and impact mills are used for primary and secondary crushing. After crushing, the size of the material is further reduced to 50 micrometers ( m) or smaller by grinding, using smooth rolls, media mills, autogenous mills, hammer mills, or jet mills.

Crusher Efficiency Calculations

Simulations of the jaw crusher incorporating a description of particle breakage can be a useful tool in design and optimization of the machine, since DEM may be an excellent tool to predict machine performance, including assessing measures that are hard to obtain experimentally, such as the stress gradient on the jaw plates. 5) A material crushed in a Blake jaw crusher such that the average size of particle is reduced from 50 mm to 10 mm with consumption of energy 25 10 points kW/(kg/s) what wou d be the consumption of energy needed to crush the same material of average size 75 mm to an average size of 25 mm if Rittingers law is applied 3.457 5.329 8.333 10.437

It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.
