crusher consists of a heavy cast-iron, or steel, shell/frame which includes in its lower part an actuating mechanism (eccentric and driving gears), and in its upper part a cone shaped crushing chamber, lined with wear resisting plates (concaves). Construction detail and working of the crusher is as under.

The normal weight coarse aggregates for the Ethiopian construction sector are produced by both, traditional and modern means. In preparing crushing it manually by hammer which consumes long time, take maximum money, need many human powers and has many injure on human body. So impact stone crusher machine will come over these problems.

Crushers are essential machines in several industries for particle size reduction. They are invaluable in laboratories (higher institutions and research centres), the mining and construction industries. Available crushers are imported and very expensive. This has pushed some workers around Nigeria to crush stones with crude materials and manual labour, to meet …

resisting crushing of a 50 mm diameter stone is its cross-sectional area, πr2. The stress acting on the stone is given Equation (5) as given by [13]. 𝜎 è æℎ𝑖 = 𝐹1 𝐴 (5) where 𝜎 è æℎ𝑖 is the crushing stress in MPa, F 1 is the force resisting crushing in N and A is the area in m2. F 1 =100×106×𝜋0.0252=196.35 kN

theoretical efficiency of the double roll crusher when crushing limestone was 60% while that of kaolin was 80%. Keywords: Double roll, crushing, Particle size, design analysis, solid mineral. 1. Introduction Crushing" and "grinding" have been in use since the beginning of human existence.

Crusher is one of the major size reduction equipment that is used in metallurgical, mechanical, and other similar industries. They exist in various sizes and capacities which range from 0.1 ton/hr. to 50 ton/hr. They can be classified based on the degree to which they can fragment the starting material and the way they apply forces. Based on the mechanism used …

application people is that the crusher must have an adequate amount of evenly distributed feed. Figure 8 shows the effect of poor and good feed distribution. If the feed is correct, the crusher will have maximum produc- tivity (highest average crushing force) for minimum mechanical stress. A crusher normally cannot be properly fed from a vibrat-

The grinding stone consists of a lower stationary one, called the Quern stone and an upper stone which is mobile and called the hand stone. The oldest known flour milling devices are saddle stones (Williams and Rosentrater, 2007). A saddle stone is a cradle-shaped piece of hard stone which holds the grain. The hand stone can either be a

A grain size reduction hammer mill for crushing corn (Zea mays L.) was designed depending on variety characteristics and by using computer aided design "ANSYS" software.
