DESIGN AND ANALYSIS OF A HORIZONTAL SHAFT IMPACT

a) Primary crusher The raw material from mines is processed first in primary crushers. The input of these crushers is relatively wider and the output products are coarser in size. Example Jaw crusher, Gyratory crusher, Impact Crushers, etc. b) Secondary crusher- The crushed rocks from primary crusher are sent to these secondary

Below the surface: Setting up an underground primary jaw

4/1/2014· Jaw crushers are the most common solution in underground applications when the throughput is below 1000 tonnes per hour, depending somewhat on the scalping solutions. Above 1000 tph, primary gyratory crushers are an option. After the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout. The capacity is also determined by the feed

Primary Crushing Mineral Processing & Metallurgy

17/3/2017· The term “primary crusher,” by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant. The factors influencing the selection of a crusher for this service are much the same, regardless of how many

Primary Crusher Selection & Design

5/5/2018· How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity of 2.6.

2.1 The primary crusher. The primary crusher is located in the quarry and consists of a McLanahan 48″x72′ Shale King Crusher rated at 1,000 TPH (Tons Per Hour). The driving flywheel has a diameter of 2.5 meters and is motor driven through six v-belts. The capacity of the primary crusher had to be increased to 1,250 TPH to produce enough material to serve the wet and both dry lines in the plant.

Jaw Crusher Working Principle

The primary rock breaker that is most commonly used in small plants is a jaw crusher of the Blake type, a typical section of which is shown in Fig. 4. It will be seen that the pitman (226) is suspended from an eccentric on the flywheel shaft and consequently moves up and down as the latter revolves, forcing the toggle plates outwards at each revolution.

Crusher an overview ScienceDirect Topics

The common primary crushers are of jaw and gyratory types. The jaw crusher reduces the size of large rocks by dropping them into a “V”-shaped mouth at the top of the crusher chamber. This is created between one fixed rigid jaw and a pivoting swing jaw set at acute angles to each other.
