The primary crusher is usually a jaw crusher or a gyratory crusher, which operates by compressing the material between two surfaces. The jaw crusher works by moving the material between a fixed and a moving plate. ... +86 info@crushing-machine 19F, Suite B, Global Trade Mansion, Wenfeng Avenue, Anyang, Henan, China. …
There are two main types of primary crushers-gyratory crushers and jaw crushers. Gyratory crushers are the most common for new operations. Secondary crushers are lighter-duty and include cone crushers, roll crushers, and impact crushers. Generally, the feed to these machines will be less than 15 cm, and secondary crushing is usually done on dry ...
Wedges are used to adjust the gap between the jaw dies and the toggle plate, while toggle plates transmit power to the crushing chamber.

The gyratory crusher, whether used as a primary or secondary. is essentially a gravity-type machine. Material flows vertically from top to bottom. It receives a large coarse feed, usually run-of-mine, and its product normally requires additional crushing before produc- ing the final product. The gyratory crusher is a pressure crushing
Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap between the bowl liner …
Gyratory crusher. A gyratory crusher is a type of crusher that uses a mantle to guide the crushing process. The mantle is suspended on an eccentrically rotating shaft, which causes the mantle to gyrate. The gyratory crusher has a higher capacity than a jaw crusher. It is often used for primary crushing in the stone crushing industry.
A jaw crushing machine is a type of equipment used to break down hard materials, such as rocks, minerals, and ores. It consists of a fixed jaw plate and a movable jaw plate that is positioned in a V-shaped configuration. ... and gyratory crushers. In general, jaw crushers are a good option for applications where the material is relatively hard ...
The gyratory crusher is a heavy machine consisting of an iron or steel frame with an actuating mechanism and a cone-shaped chamber lined with wear-resisting plates. A steady rest, called a spider, supports the upper part of the machine. ... At its upper end, it connects to a crushing head or mantle via a heavy nut that allows for some vertical ...
Cone crushers resemble gyratory crushers from the technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed.
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It is …
Typically, rocks will go through multiple rounds of crushing to reach the desired size. Crushers are also used in construction material recycling and mining operations. Powerscreen Premiertrak 330 Mobile Crusher. Variants. These machines come in three main types, jaw crusher, cone and gyratory crusher, and impact crusher. Jaw crushers ...
The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the …
No discussion of primary crusher selection would be complete without a comparison of the two leading types: the standard gyratory crusher and the Blake jaw crusher.Although their fields of application overlap to a considerable degree (at least in the realm of primary crushing) there is no real conflict between these two machines; one supplements …
The gyratory crusher, on the other hand, is used for large primary crushing applications. It has a conical head and concave surface that are lined with manganese steel. The gyratory crusher uses a gyrating motion to crush the materials. Secondary Crushing. Secondary crushing is the second stage of crushing that takes place after the primary ...
The main features of a Gyratory Crusher include a tall crushing chamber lined with replaceable manganese wear plates, a main shaft with head and mantle, and a spider to anchor the top of the main shaft bearing. ... Feeder-Breakers, which combine both feeding and crushing into one machine, are used for the primary crushing of friable materials ...
The SUPERIOR® gyratory crusher is a compressive style crusher for primary-stage applications. Its steep crushing chamber and long crushing surfaces provide exceptionally high capacity and long liner life.

2. Gyratory crusher The gyratory crushers are rarely used in the coal industry, but they can be used for primary crushing of large dry or slightly wet coal. They have a larger feed opening than the jaw crusher and a larger output. A gyratory crusher works by compressing the coal between a mantle and a fixed concave liner, similar to a cone crusher.
History tells us, it was in 1830, the first US patent was issued on a rock crushing machine. ... sidelight of these early days occurred in 1883 when a contest was staged between a Blake jaw crusher and a Gates gyratory crusher. Each machine was required to crush 9 cubic yard of stone, the feed-size and discharge settings being similar. The ...
Suppose that a tentative selection of a 3.5″ open- side discharge setting has been made for a standard gyratory primary crusher to be used for crushing quarry-run limestone. Referring to the table which lists percentages of product passing an equivalent square opening, we find that 85 to 90% of the crusher product should pass a 3.5″ square ...
Gyratory Crushers: This type of crusher uses a mantle that gyrates or rotates, crushing the material between the mantle and the concave. Impact Crushers: This type of crusher uses a rotating impeller to create a high-speed impact force, breaking down the material. Advantages and Disadvantages of Primary Crushers
