Stone crushing machine types and unique features

 

This type impact crusher has Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the machine work normally.  Vsi crusher's special feed opening structure make it possible that center feeding and ring feeding comes together, in order to meet requirements of different stones. In addition, this equipment can not only crush stone, but also iron.
This known mill is a so-called vertical mill and comprises a casing or mill body with a horizontal grinding table positioned within the mill body mounted for rotation about a vertical axis. Drive means such as a motor and a gear reducer, situated beneath the grinding table, are provided for rotating the grinding table. Vertical Mill rocker arms are mounted in the roller mill structure and in the end of each rocker arm a grinding roller is mounted for rotation about an axis, which is situated at a predetermined angle to the table. Shape of material-thronging device of our vsi crusher is better designed, which improve the utilization ratio.
Optimized arrangement design of wear resistant materials increase the service life of the machine by over 40%, thus decrease the cost by over 40%.
The mainframe is made with rivet hot technique, which enhances intensity of structure and tenacity, and ensures stable performance.
 The load-carrying mill structure is assembled from a plurality of mill stands, one for each grinding roll. Each grinding roll assembly, consisting of a grinding roller, axle, hub and bearing, requires a mill stand to support the force mechanism, such as a hydraulic cylinder, which generates the grinding pressure and which is mounted in the mill stand. The new anti-entrapment devices shown at Intermat by both JLG and Genie sparked much discussion around the show. Genie was also allowing AFI-Uplift to show its Sanctuary Zone and Nationwide Platforms its SkySiren. Niftylift continued its commitment to its SiOPS - sustainable involuntary operation prevention system.
Spring cone crusher is the earliest cone crusher appearance in the world, and cone crusher of this model is used widest and larger quantity crush mechanism in present. With the improvement of the series of cs cone crushers, the spring cone crusher's structure is more perfect and the technology parameter is more advanced, so this series of cone crusher has excellent performance in the aspects of manufacture, installation, use and maintenance etc.By turning the rockers well as oil jack maintenance, the hard surfacing and lining and plates can be maintained within short time, which decreases the outage loss. Some of the devices can be retrofitted others are built into the basket, they are all designed to prevent serious injury or fatalities occurring if a (usually) boom operator fails to notice an overhead obstruction and become trapped between the obstruction and the controls.
