36”superior Crusher Series

The 36” Superior Gyratory Crusher is an intermediate crusher, especially suitable for the reduction of coarse material from a primary crusher, such as our small jaw crusher or similar, which operates with a discharge setting of up to approximately 170mm C.S.S. Three versions are available, with feed openings of 325 mm (13”), 275 mm, and 225 mm (9”). The crusher is equipped with a water/oil or air/oil heat exchanger. The air/oil type is available in two versions: standard and tropical (for maximum ambient air temperatures of 320°C and 400°C, respectively). If a sudden power failure stops the crusher under load, the mantle can be lowered so that the crushing chamber can be easily emptied. The concave ring can easily be rotated to even out wear.

Remote Setting Indication and Adjustment

A remote setting indication system can be supplied as an optional extra. A special Hydroset tank is used and fitted with a setting transducer, which is electrically connected to a remote setting indication unit, allowing the crusher setting to be displayed in the plant’s control room. The setting can then be remotely adjusted by a pushbutton-controlled pump and solenoid valve.

Automatic Control Systems

We can supply an automatic setting regulation system as an optional extra. The system automatically monitors the motor load, the Hydroset pressure, and the setting, and automatically regulates the latter in accordance with the load on the crusher. This provides optimum crusher utilization and significantly improved crushing results. Additionally, for special applications, another system is available that controls both the feed and the setting. These systems are described in a separate leaflet.

Product Curve

The product analysis depends on many factors, among which are the O.S.S., the crushing chamber design, and the type of material being crushed. Over the years, we have accumulated a lot of data about product curves, and for most applications, the curves given at the bottom of the page provide good approximations of the product that can be expected. In general, the product curve is directly
related to the O.S.S., and the percentage of the product that will be smaller than the O.S.S. is normally 85%.

Selection of Crushing chamber

The selection of the most suitable crushing chamber mainly depends on the feed size and the desired product fraction. Maximum feed size recommendations are given in the table on the next page. In doubtful cases, contact us for advice. Two topshells and three crushing chambers are available on 36” Superior Crushers to meet different requirements. One topshell can be fitted with concaves providing 9” (225mm) and 11” (275mm) feed openings, while the other topshell can be fitted with concaves providing 11” (275mm) and 13” (325mm) feed openings. The size designation of a Superior Crusher consists of the feed opening width and the mantle diameter at the bottom of the crushing chamber, both expressed in inches.
A 13-36” Superior, for example, has a 13” wide feed opening and a 36” diameter mantle.
