crusher. Primary Crusher — The first crusher in a crushing system into which material is fed. Succeeding crushers in the system are referred to as secondary or tertiary crushers. Product — Output from the crusher. Reduction Ratio — The ratio of the top size of input material to the top size of crusher discharge.
2.2.1 Small Size Stone Crushers There are different types of small crushers in various states with a production capacity ranging from 3 to 25 TPH. Typically, the units having only one Jaw type crusher used as primary or secondary crusher along with one or maximum 2 screens are grouped as small stone crushers. 2.2.2.
In cement plants increased airflow through the cooler reduces secondary air temperature, and therefore, the flame temperature, thus requiring even more fuel to heat the charge to the required process temperature and the increase in fuel consumption is much greater than that needed just to

The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.
These are consider as secondary crushers with feeds 12-75 mm in size and the product is 12-1 mm. The product size can be estimated as D p = 0.04R+d
crushers to extend plant lifetime and boost production. The modular concept makes the C Series jaw crushers easy to install. The crusher can be installed as one compact module that includes all the necessary auxiliaries around the crusher itself. The crusher can be installed within a few days, minimizing on-site engineering and fabrication.
6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed.
Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher’s two jaw; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds
2. GYRATORY CRUSHERS The original patent for the gyratory crusher was granted to Phile- tus W. Gates in 1881. This fint crusher was used by the Buffalo Cement Co. At the time these early gyratory crushers were developed all mining and quarrying, either underground or open pit, was done

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.

Product — Output from the crusher. Reduction Ratio — The ratio of the top size of input material to the top size of crusher discharge.
The large boulders are extracted from the solid bedrock with blasting. This very first stage in the process is needed to enable these very large rocks to be crushed by smaller, secondary jaw and roller crushers, which create the smaller sizes for screening to produce the basic building materials like gravel, grit or sand.

Cone crushers are similar to gyratory crushers in that they have a mantle that rotates within a bowl, but the chamber is not as steep. They are compression crushers that generally provide reduction ratios of 6-to-1 to 4-to-1. Cone crushers are used in secondary, tertiary and quaternary stages.

and shape, mostly based on specifications. Most secondary crushers are cone crushers and horizontal shaft impacts. For coal, many times, rotary breakers are used as primary crushers and ring granulators are used as secondary crushers. Information on construction and working of various crushers is given in the following chapters.
discharge end (associated sinter crushers and hot screens), cooler, and cold screen. The windbox exhaust is the primary source of particulate emissions, mainly iron oxides, sulfur oxides, carbonaceous compounds, aliphatic hydrocarbons, and chlorides. At the discharge end, emissions are mainly iron and calcium oxides.

Crushers, screens and dust-collection fans all contribute to high noise levels. Air-cooled lubrication systems are not only noisy, but often leak oil. Well-balanced, choke-fed crushers, dust-enclosed screens and dust collector fans with silencers can keep noise levels under control. Recirculating water can be used to cool crusher lubrication
