CM 420 – TEMPORARY STRUCTURES LESSON 4: COFFERDAMS Page 2 of 13 5. Cellular: Cellular cofferdams are used only in those circumstances where the excavation size precludes the use of crossexcavation bracing. In this case, the cofferdam must be stable .
· Uses: Roller mill is used for crushing and cracking of seed before extraction of fixed oils and also used to crush soft tissue to help in the penetration of solvent during extraction process. 10 11. HAMMER MILL Principle: The hammer mill operates on the principle of impact between rapidly moving hammer mounted on a rotor and the powder material. 11Fig: Hammer mill

Following crushing, screens with two or three decks and different opening sizes separate the aggregate material into different size egories (classes) for further crushing or stockpiling as a saleable product. Dust Removal Dust removal is screening out the unwanted very fine particles. Dewatering Dewatering is straining of unwanted water.
the crushing chamber that is composed of rotor, impact plate/ anvils, hammers/ blow bars, by means of which intense shock phenomenon will act predominantly, and the material will be crushed along its natural crack and hence bulge.
· This method involves a base machine, such as an excavator, fitted with a long demolition arm consisting of three sections or a telescopic boom. A demolition tool, such as a crusher, shears, or a hammer, is attached to the end of the arm and is used to break up the building from the top down.
· Impactbased equipment commonly uses hammers or media. The pros and cons of several types of sizereduction equipment are shown in the table. Rolls, in particular, can produce very fine particles. Rolls are used in flour milling, where crushing yields differentsized particles, allowing separation of purified flours.
The Standard and NonClog Industrial Hammermills are designed to reduce the material to a nominal 3" to 5" (75mm to 25mm) output. These are primary stage crushers, commonly followed with Centerfeed Mills or other types of secondary stage crushers. The HammerMaster is also a secondary stage crusher in that the maximum feed size is 6" (150mm).
