The crushing mode of the jaw crusher is a curved extrusion type. Its main working part is two jaw plates, fixed jaw plate (fixed jaw) and movable jaw plate (movable jaw). The crushing space is formed by the jaws.
However, the crushing force of the single-cylinder hydraulic cone is slightly insufficient, especially for crushing hard materials. Because the adjustment method is to lift and lower movable cone, the wear and tear of concave is not uniform under the condition of uneven feeding. Besides, the oil cylinder is at the bottom, leaving small space for lower parts, which brings certain difficulties to maintain.
If a non-breakable tramp metal enters the machine, it is essential to open the crushing gap to let the tramp material pass. This is achieved by using the so-called floating roll, which is supported in pivoting rocker arms. The rocker arms are supported by the lower housing via hydraulic cylinders. In order to guarantee parallel retraction of the floating roll, the rocker arms are connected with each other over a torsion shaft. The rotational reaction of the floating roll allows an almost frictionless movement and a great escape path.
In this process use blow bars & rotor hammer, they are impacting on the materials and causing or breaking in parts, propels material on the high speeding against them affecting curtaining walls by crushing impacts of the materials.
Nordtrack™ crushers are designed especially for asphalt recycling, concrete demolition, and small scale aggregate production.
One of the benefits incorporated into the QI442 HS is the optional double-deck modular hanging screen system. This system is interchangeable and offers the flexibility for the crusher to operate in open or closed circuit. The design enables set-up in less than 30 minutes and can be fitted without the use of additional lifting equipment.
Quartzite is a sandstone that has been metamorphosed. The process of metamorphism heats and compresses the rock and often causes the sand grains to become welded together. This can produce an extremely durable rock that usually does not have the freeze-thaw concerns of sandstone. Quartzite can actually be so durable that it is difficult to mine, handle, and transport to construction sites.
There are many different types of crushers available in the market including compression crusher and impact crusher. When it comes to compression crusher, there are many different types such as cone crusher or jaw crusher, whereas impact crusher types include vertical shaft crusher and horizontal shaft crusher. Typically impact crushers are chosen for less abrasive materials whereas compression style crushers are used for crushing more abrasive materials.
This crusher has no bottom grating bar. However, since the materials after impacted by the hammers do not form efficient wide-angle impacting act with the lining board, its tertiary crushing ability is relatively weaker than that of the horizontal type tertiary crusher. In addition, its hammer is an integrated structure with short abrasion cycle, and the changing process of the hammers is complicated and the changing of the bearing is more difficult.
Widely used in the Quarrying and Mining industries, the PE Series Jaw Crushers are Single Toggle Roller Bearing machines designed to operate as Primary crushing units in medium to hard rock applications. The swing jaw is activated by an eccentric main shaft which lifts and thrusts the swing jaw towards the fixed jaw, thus creating the crushing action. The crusher discharge setting (CCS) is variable by mechanical shim adjustment of the swing jaw behind the toggle plate. eccentric main shaft which lifts and thrusts the swing jaw towards the fixed jaw, thus creating the crushing action.
