Effect of throw The necessary data for studying the effect of throw on the performance of jaw crushers are given in Table 2 (Hersam, 1923). For calculating the values of K2, the value of Kg for materials like granite and traprock were set equal to one, and the values of KI were calculated with Eq. (10).

Impact Test of Stone. The resistance of stones to impact is found by conducting tests in impacting the testing machine [Below Figure]. It consists of a frame with guides where a metal hammer weighing to 15 kg can freely fall from a height of 380 mm.
Impact stone crusher involves the use of impact rather than pressure to crush materials. The material is held within a cage, with openings of the desired size at the bottom, end or at sides to allow crushed material to escape through them. Impact stone crusher is used with soft materials, medium to hard stones and medium hard metallic ores.

· during the operation, there will be no negative impact on environment as it is a stone crushing factory which does not use any chemicals. The stones are dry and hence no effluent. The type of rock to be crushed is very hard black type with specialized equipment and therefore minimal emissions is expected to be released to the atmosphere.
· Impact crusher. It is the crushing equipment for medium and fine sized stones, which can crush medium hardness stones of various materials, and the finished product particle size is better, therefore. It is generally used for the second stage of the material crushing and shaping.
crushed waste can be taken from the bottom part. The removed waste is in the shape of the bin and holds together as a single solid model and is easy to transport. 3. OPERATING MECHANISM This crusher works on the simple mechanism called crank and slotted lever mechanism. When the motor is .
