Hammer Crusher Mechanisms
Transcribed image text: 3.51 The mechanism shown schematically in Figure P3.51 is proposed for a rock crusher. The crusher hammer rotates through an angle of 20°, and the gear ratio R/Rp is 4:1, that is, the radius 4G is four times the radius ry. Contact between the two gears can be treated as rolling contact.

be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact crushers. 5.1.3 Crushing mechanisms and product size distributions. The crushing action of a crushing machine is described most usefully through the classification
Figure 6.32 illustrates a rock crusher. For this mechanism: 1.Draw a Kinematic Diagram 2.Sketch an Instant Center Diagram 3.Locate the Primary Instant Centers 4.Use Kennedy’s Theorem to Locate the Other Instant Centers.

direct feed from haul/dump trucks. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength. The crusher is the workhorse of the hard rock crushing industry. A gyratory crusher uses a mantle that gyrates (rotates) within a cone shaped inner surface

3. OPERATING MECHANISM This crusher works on the simple mechanism called crank and slotted lever mechanism. When the motor is excited using a power source (i.e.3-phase power supply in this case) the shaft starts to rotate which in turn rotates the pulley which is connected to the motor by means of a belt drive.

The double roll crusher is the most common rock stone crushing machine. Its crushing ratio is usually lower than in other crushers, so it’s suitable for fine crushing. The roll crusher uses compression to crush materials, and the reduction ratio is 2 to 2.5 so roller crushers are not recommended for abrasive materials. Hammer Crusher

The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher and in these machines
