Download as PDF Set alert About this page Jaw Crusher In Mineral Processing Design and Operations Second Edition 2016 42 Design of Jaw Crushers Jaw crushers are designed to impart an impact on a rock particle placed between a fixed and a moving plate jaw The faces of the plates are made of hardened steel The angle of nip the

a moving jaw in a welded or cast steel version as well as an eccentric shaft made of highgrade forged steel The jaw crushers with a double toggle system are either built with heavy or light welded steel housings with a moving jaw and a pulling rod in either welded or cast steel versions as well as an axis

Figure 51 Schematic diagram of a crusher showingg the open and closedside settings 51 Jaw and Gyratory Crushers Jaw and gyratory crushers are used mostly for primary crushing They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material The capacity of the crusher is determined by its size

Side of the crusher fitted with a grooved pulley couple to the crusher drive NON DRIVE SIDE Opposite side of the crusher form the drive side FLYWHEEL Large wheels used as part of the crusher drive and to store inertia NIP ANGLE Inclusive angle between jaw plates indicative of the crushers ability to crush and draw rock JAW PLATES

The closed side setting can be calculated by deducting the stroke from the OSS CSS is the most important crusher parameter since it defines the maximum product size and has significant bearing on capacity product gradation power draw and wear Nip angle The nip angle is the angle between the fixed and movable jaw dies

A larger feed opening increases material intake and ensures that the rocks enter the jaw crusher’s cavity without restrictions A steeper nip angle decreases operating costs by reducing wear on jaw dies and speeds up material flow down in the cavity The stroke is amplified from top to bottom leading it being longest in the bottom of the cavity

Steep nip angles provide an aggressive bite at the jaw crusher opening The maximised rotating speed and flywheel mass together with an optimised toggle and nip angle help to increase production and reduction performance This allows the crusher to run smoothly and Open the catalog to page 4

The nip angle is affected by the distance between the rolls The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle It depends on the surface characteristics of the rolls Usually the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°

Jaw crushers are used mainly in first stage primary crushing applications and are ideal for use in quarries and recycling demolition operations Optimum Nip Angle PDF DOWNLOAD jaw front BROCHURE Böhringer Horizontal Jaw Crusher for difficult to handle steel rebar in recycling applications BROCHURE PDF DOWNLOAD

The Nordberg C130 jaw crusher on the Lokotrack LT130E takes your capacity to a new level in largescale quarry applications A deeper 1 000 mm 40” feed opening is able to handle coarser feed material and it greatly reduces the need for blasting A small nip angle and excellent kinematics ensure aggressive crushing

Angle Of Nip In Roll Crusher Formula You are here Home Products Angle Of Nip In Roll Crusher Formula The main problem in measuring slip angle is that it is a very small angle a change of 05 is already significant slip angle also varies quickly so fast changes above 1hz are significant there are two main ways to measure slip angle of a tire

Design Fabrication and Testing of a Double Roll Crusher Egbe EAP 1 and Olugboji OA1 include jaw crusher gyratory crusher and roll crusher A double roll crusher consists of two rolls and the two rolls meet to form the nip angle By simple geometry the nip angle between two rolls of radius R the size of the particle

The nip angle is affected by the distance between the rolls The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle It depends on the surface characteristics of the rolls Usually the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°

Jaw Crushers are sized by the top opening of the crushing chamber For example a 32 x 54 Jaw Crusher measures 32 from jaw die to jaw die at the top opening or gape opening and 54” across the width of the two jaw dies The narrower bottom opening of the crushing chamber is used to size the discharge material
