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. b. Secondary crusher: The crushed rocks from primary crusher are sent to these secondary crushers for further size reduction. c.ine crushe F r
Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers. 13.3.1.1 Primary Crusher Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size.
Jaw crushers are mainly used in primary crushing stages and are rarely used for secondary crushing. As a compression crusher, this type of machine generally produces the coarsest material because it breaks the rock along its natural lines of weakness.
Select a jaw crusher for primary crushing and a roll crusher for secondary crushing to produce 160 tph of limestone rock. The maximum-size stone from the quarry will be 22 in. The stone is to be crushed to the following specifications: Specify the size and setting for each crusher selected.
Crushers are classified into three types based upon the stage of crushing they accomplish. These are (i) primary crusher, (ii) secondary crusher, and (iii) tertiary crusher. The primary crusher receives material directly from run of mine (ROM) after blasting and produces the first reduction in size.
All components of the crushing site depend on the proper operation of the primary crusher, which is why it is vital to select the right crusher for the job. Defining the intended use of the primary crusher. The first step in selecting a primary crusher is to proceed at a high level. It is necessary to define the intended use of the crusher.
Generally gyratory crushers, jaw crushers, high speed double roll crushers, low speed sizers, impactors and hammer mills are used as primary crushers. In the secondary and subsequent stages, the material is further reduced and refined for proper size and shape, mostly based on specifications. Most secondary crushers are cone crushers and

Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers. 13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage
Select a jaw crusher for primary crushing and a roll crusher for secondary crushing to produce 160 tph of limestone rock. The maximum-size stone from the quarry will be 22 in. The stone is to be crushed to the following specifications: Specify the size and setting for each crusher selected.
Primary crushing with impact crushers. The primary impact crusher offers high capacity and is designed to accept large feed sizes. The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71") in the largest model.
Primary Impact Crushers are preferred for their high capacity and reduction ratios in crushing soft and medium hard rocks like limestone, gypsum. Due to their operating principle, reduction ratio is higher than in jaw crushers.

The term “ secondary crushing ” has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed. The term should not be used, as it sometimes is, to
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

Primary crushing with impact crushers. The primary impact crusher offers high capacity and is designed to accept large feed sizes. The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71") in the largest model.
These crushers offer an ideal solution for primary crushing applications involving hard, abrasive materials such as granite or recycled concrete. Efficient and less costly to operate because of their minimal moving parts, jaw crushers are well suited to applications where the primary objective is to reduce raw feed material to a manageable size, usually down to about 150mm.
The crusher was born out of a need for a high capacity underground primary crusher that did not require a primary feeder, scalper, and the associated infrastructure therein. Minimizing the need for high cost stationary grids to control topsize underground was a requisite, and the topsize acceptance was met with the UG design.
In general, crushing is carried out in three stages, depending on the desired size of the material. Primary Crushing. This is the first stage of the crushing process. In general, the size of the feed material, which is between 800 and 1500 mm, is reduced to between 150 and 300 mm. Secondary Crushing. This is the second stage of crushing.
