220.127.116.11 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 for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.
· The crusher weighed 225 tons and was belt- driven by a 250-B.HP. motor to give a speed of 23 r.p.m. to the crushing-roll. The feed-size reached a maximum of 4 feet by 7 feet and the crusher, when adjusted for a 7-inch product, gave an output of 700 tons per hour.
Gyratory crushers generally cost less than $1500 per hour to run, while Jaw crushers cost less than $200, including electricity (Infomine, 2008). Rules of Thumb • A 42-inch gyratory crusher produces approximately 2.4 tons per horsepower-hour (2.9 t/kWh).
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
· Gyratory and jaw crushers are always rated at certain open-side or close-side discharge settings. In order that we may select the particular curve, of a group of curves, which will most nearly represent the product of a crusher having any given discharge setting, it is important to know approximately what percentage of the total output will pass a screen opening of equal dimension.
Gyratory crusher is a new type of crusher which can replace fine jaw crusher or cone crusher. The gyratory crushing equipment has a bright future in the mineral processing market. Its working part is a high-speed rotary crushing roller, which is coupled with a pair of curved crushing plates arranged symmetrically on the left and the right to form two optimal crushing cavities for the pliers.

The base is the section of the crusher that provides an entry point for the drive assembly and oil system. It also provides support for the working surface of the ...
Gyratory crusher operating mechanism. United States Patent 2486478. Abstract: This invention relates to improvements in gyratory crushers more particularly to improved mechanism for driving the main shaft of a gyrat6ry crusher. Crushers of this general type are disclosed in my U. S. Patents Nos. 1,754,895, 1,985,098 and 2,208,639 for example.
· Secondary Gyratory Crushers. The use of large primary crushers made secondary crushing necessary, but this department was taken care of nicely by the existing lines of standard gyratory machines. In commercial crushed stone plants, there was gradual increase in the number of products, but generally a sufficient demand existed for the coarser ...

· The jaw crusher will handle sticky,''or dirty feed better than the gyratory, there being no diaphragm below the crushing chamber on which such material can pack. Routine maintenance and repair jobs are generally more easily accomplished on the jaw crusher than on the gyratory. Major repairs are about a stand-off.
The cone crusher has 2.5 times higher rotating speed and 4 times larger swinging angle than the gyratory crusher, so the ore is impacted quickly. Therefore, it is advantageous to the ore crushing, the crushing efficiency is high. 2. Different applications. In large quarries, gyratory crushers are often used as primary crushers.
gyratory crusher liners. Due to its ability to work-harden during operation, it has proven to be versatile, and works well in a majority of applications. We offer three standard grades for gyratory crusher liners, allowing you to quickly address changing ore characteristics. By varying the
· A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer''s data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.
· Cone crusher is similar in operation to a gyratory crusher, but with less steepness in the crushing chamber and more of a parallel zone between crushing zones. A cone crusher breaks material by squeezing the material between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner.
· Details the Working Principle of Crushers (Jaw and Gyratory) using mechanical animations and physics. Working Principle of Crushers On left is a showing of the "standard gyratory with straight concaves" is a section through any vertical, radial plane in the crushing chamber of one of the intermediate sizes of the crusher.

4 Gyratory crushers FL''s legacy of quality crushers dates back to the Traylor and Fuller-Traylor gyratory crushers of the early 1900s. FL crushers have continuously withstood the harshest requirements found in the world''s mines and rock quarries.
· To study and optimize the gyratory crusher performance, taking the process of crushing iron ore by the gyratory crusher as the specific analysis object in this paper. First, the discrete element method (DEM) analysis model of the iron ore based on the bonded-particle model (BPM) is established.
Gyratory crushers were invented by Charles Brown in 1877 and developed by Gates around 1881 and were referred to as a Gates crusher . The smaller form is described as a cone crusher. The larger crushers are normally known as primary crushers as they are designed to receive run-on-mine (ROM) rocks directly from the mines.

The gyratory crusher has no rival in large plants with capacities starting from 1200 t/h and above. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Also, primary gyratories require quite a
· Gyratory crushers or cone crushers are characterized by crushing or crusher heads having a generally cone-shaped outer surface, which are mounted to undergo gyratory motion. The cone-shaped crushing head of a gyratory crusher is generally centered about a head axis that is angularly offset from a vertical crusher axis generally centered through the crusher.
