8 FLS —Spare wear parts for Gyratory Style Crushers Custom threaded mainshaft sleeve We create customised threaded mainshaft sleeves to protect your mainshaft. With the threads on the sleeve instead of the mainshaft, removing and installing the inner head nut no longer risks damaging the expensive mainshaft. Custom throw eccentric bushing
The lubrication of Gyratory crushers may be one of the special problems that the Jaw crusher isn't as readily exposed to. This crusher, because it may be loaded from two sides, often is used in an open pit situation where large ore carriers are dumping directly into the crusher. This means that the machinery is exposed to whatever climate it ...

A gyratory crusher consists of a concave sur-face and a conical head; both surfaces are typically lined with manganese steel. The top of the shaft attached to the crushing cone is …
I have experienced many problems due abnormal power draw behavior of the electric motor in a primary gyratory crusher in iron ore crushing, especially when the service life of the first row concave comes to an end. I suspect that the current eccentric throw of the mainshaft (52mm) is higher than is really necessary.
The crusher has a robust design, adjustable eccentric throw, and a constant intake opening. This crusher is suitable for a high-capacity secondary crushing application. CS430 cone crusher is characterized by the large intake capability and the high capacity in relation to size, proving to be a versatile and efficient option for many ...
The gyratory crusher has been built in three types known respec- tively as the suspended-spindle, the supported-spindle and the fixed- spindle type. The second type, with the hydraulic piston as the sup ... the eccentric throw is the same at the top of the chamber as it is at the bottom. The eccentric is very long and extends practically the

Shortly after the start-up of the loaded gyratory crusher, a severe failure issue occurred in the eccentric bushing of the crusher. Based on the analysis of working conditions and force, the failure mechanism of the eccentric bushing is studied in detail by combining macroscopic analysis, finite element analysis, scanning electron microscopy …
A gyratory crusher size 33–55 was designed to accept feed of size 68 cm × 178 cm. The open-side setting of the discharge opening was 10.2 cm. The rate of gyration was 175 per minute. Calculate. 1. the capacity of crusher for an eccentric throw of …
The gap is opened and closed by an eccentric assembly in the bottom shell, which causes the central vertical shaft to gyrate. The vertical shaft is free to rotate about its own axis. …
In this crusher, an eccentric sleeve is inserted between the fixed vertical shaft and the movable vertical cone ( Fig. 4.3 B). By rotating this eccentric sleeve, the axis of the cone is given a cylindrical motion with a pinching action on the material being crushed. 6. Gyratory crushers have larger capacity because the action is continuous, as ...
Cone Crusher from GUR-SAN Construction Machines Ltd. Co., Turkey. Cone Crusher, Find quality Cone …. This high RPM combined with aggressive eccentric stroke and wide angle crushing chamber ensure optimum capacity and cubic shape of the product.
With relatively high speeds of 480 to 580 rpm and small eccentric throw, the machine produced a uniform produce with minimum fines. ... Studies have shown that converting the second stage gyratory crusher to a 10 Ft. Standard crusher shows most potential because the major auxiliaries required for the crusher, such as crane, conveyors, etc., are ...
