Design and production of an indigenous roll crusher from locally available materials for low hardness rocks was carried out in this work The throughput capacity of the machine was /hour The theoretical efficiency of the double roll crusher when crushing limestone was 60% while that of kaolin was 80%
In principle machine foundations should be designed such that the dynamic forces of machines are transmitted to the soil through the foundation in such a way that all kinds of harmful effects are eliminated Barkan 1962; It is this aspect that makes modeling and analysis a very important part of design Foundation Soil Frequency Safety
design of jaw crusher pressure force In present studies these two cases were analyzed In this study coupled working forces created by kinematics of crusher and crushing process were analyzed as transient by ANSYS Mechanical and ROCKY DEM integration Research is divided into two main steps At first step DEA Discrete Element Analysis FEA
ventional foundation such as simplified design and analysis easy installation and cost savings Other advantages are • The crusher foundation is limited to a concrete deck supported by spring units and VISCODAMPERS The dy namic behavior of this system can be accurately calculated and predicted • Consequently the design of the sup
The first step in the mining and processing of nearly any mineral ore is comminution Since the oil embargo of 1979 the mining companies have been striving to reduce energy consumption and costs The first serious step was the introduction of in pit crushing in the early 1980s With in pit crushing accepted as a standard design mode the energy saving emphasis turned to
Every jaw crusher diagram is a window to the soul of this rugged machine providing vital insights to the components that make up its robust design At the heart lies two pivotal plates the fixed jaw and the movable jaw The fixed jaw as the name suggests remains stationary and serves as the backbone for the crushing process

Design principles are created to codify and formalize design knowledge so that innovative archival practices may be communicated and used to advance design science and solve future design
The impact crusher working principle involves a high speed rotor that rotates around a horizontal axis The rotor is equipped with a series of hammers that strike the material as it enters the crushing chamber The material is then shattered against the hardened steel plates that line the crushing chamber The shattered material falls through
— Jaw crusher is a kind of size reduction machine that is wide utilized in mineral aggregates and metallurgy fields The interaction between jaw plates and material particles brings the inevitable and high wear to the jaw plates throughout the jaw crusher operation that not only decreases the efficiency however also will increase the price and also the energy consumption of the jaw
