The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure 4.4).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure 4.4(a)) and it is the most widely used in primary crushing stages (Behera et al., 2014).
Gyratory crushers are frequently used in the primary crushing stage and a little less often in in the secondary stage. Gyratory crushers have an oscillating shaft. The material is reduced in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly.
Primary Gyratory Crusher High Performance GY Series. A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing

CONE CRUSHER. 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.
Gyratory Crushers. Gyratory crushers feature a conical head and concave surface (often lined with manganese steel) and break apart material by compression through what is known as eccentric movement. Like jaw crushers, gyratory crushers are often utilized in primary crushing stations, though they may sometimes be used as secondary crushers, as ...

The 1970's brought several changes for both Elecmetal and ME. In 1970, the Wood family sold the company to Evans Products Co., while in 1976 Elecmetal became part of Grupo Claro, a leading group of companies with businesses in steel, vineyards, packaging and communications. Also in 1976, ME built a new foundry in Duluth, MN, USA, positioning ...
Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing.
Gyratory crushers are operated in open circuit. The feed is limited to 1 to 1.5 meters in size. Thus, based on reduction ratio, the rock size is reduced to 10 to 15 cm. Typical reduction ratios are: Primary crusher: 3:1 to 10:1; Secondary crusher: 6:1 to 8:1; Tertiary crusher: 10:1

Crushers and Their Types. satyendra; April 3, 2015; 1 Comment ; compression, cone crusher, crusher, gyratory crusher, hammer crusher, jaw crusher, material, Ore, roller crusher,; Crushers and Their Types. A crusher is a multi dimensional machine which is designed to reduce large size materials into smaller size materials.
Jaw gyratory crushers – design and operating principle Technical data The main characteristic of jaw gyratory crushers is their enlarged feed opening which is located on one side of the crusher only. It is normally serrated and, to- gether with the upper part of the mantle, it forms the initial crushing zone. The
Gyratory Crusher Components . Gyratory crushers were invented by Charles Brown in 1877 and further developed by Gates in 1881 (they were commonly referred to as a 'Gate's crushers' in the early years). A primary crusher is designed to receive run-on-mine (ROM) rocks directly from the mines.
following are either obsolete types of gyratory crushers, of which many are still in service, or are older designs with extremely limited capacity: long-shaft spider-suspended gyratory crusher, fixed-shaft gy- ratory crusher, and short-shaft gearless gyratory crusher. The gyratory crusher, whether used as a primary or secondary.
Secondary crushing, as you can imagine, is the second stage of material processing following its initial reduction. At this stage, material will flow through perhaps a second impactor or even a cone crusher, which is effective at breaking down these types of material. There are also tertiary and even quaternary stages of crushing that exist to ...
The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 8:1.
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
