PRIMARY AND SECONDARY CONE CRUSHERS

TYPES OF CRUSHERS

EKG12
 
◊ OMZ produces a wide range of primary and secondary cone crushers with feed openings ranging from 500 to 1500 mm.
◊ Each unit undergoes final assembly and testing on special test stands, thus ensuring high quality.
◊ Our crushers are being used to process various materials including toughest titanium magnetite ores and clay containing kimberlites – at ore processing plants and in quarries around the world. Many of these crushers operate continuously without standby units.
◊ Secondary crushes are used in four-stage production after the primay crusher. The secondary crusher provides a high grade of material crushing, thus enabling a more effective use of intermediate and fine crushers.
◊ If you are looking for special application take a good look at our purpose-designed crushers which are also available. They include units for in-pit crushing on mobile platforms, for crushing ores with low surface friction, for crushing extra tough and hard materials.

The OMZ cone crushers are widely used for crushing ferrous and non-ferrous ores, diamond containing ores, cement raw materials, coals, in the construction aggregate production and in many other areas. More than one billion tons of raw materials are processed annually in OMZ cone crushers at the largest mines and quarries all around the world.

 

Wide use of our cone crushers is due to their evident advantages over other types of crushers. These advantages include:
- production of uniform, high quality crushed product
- easy operation and maintenance
- low operation costs
- simple installation

 

Built-in maintenance means save time and money

◊ The capacities are given for feed material with compression strength of 100 … 150 mpa, containing minimum quantity of moisture, clay and fines.

◊ Before your final decision on the best crusher for your operating conditions, please consult the UHM specialists.

◊ In the practice the capacity range may very depending on the physical and mechanical properties of the material to be crushed, such as feed size, moisture and clay content etc.

◊ Main drive motors with rated power which is different from the table value are available, according to the customer’s specification.

Built-in maintenance means save time and money

 

◊ The OMZ primary and secondary crushers are equipped with built-in maintenance means facilitating the time-consuming processes of installation and upkeep.

◊ The hydraulic cylinders located at the bottom shell make the installation and removal of the countershaft easier and quicker. Special hydraulic nuts ensure a reliable tightening of large diameter threaded connections, such as fixing bolts, which attach the spider, top and bottom shells, as well as the hydraulic cylinder for the discharge setting.

 

◊ The delivery set of crushers equipped with a bottom hydraulic cylinder for discharge setting includes a special carriage with a lifting platform for installation or removal of the hydraulic cylinder.

◊ Other options include:
-a device for tightening the crusher mantle nut
-a crusher mantle removal device
-a device for the disassembly of the threaded spider suspension of the mainshaft
- hydraulic jacks to disconnect the taper connections of the crusher housing parts.
