Each jaw crusher comes with feed hopper feed hopper interface drive and subframe with v belt guard and motor bracket our unique guarding retraction arrangement and toggle plate stop Deep symmetrical crushing chamber and optimized nip angle maximizes size reduction and production capacity; Wider intake opening offers possibility to
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°
The feed opening has two dimensions a width and a depth The feed opening depth is a critical dimension because it dictates the maximum feed size a given jaw crusher model can accept Callout Description Callout Description 1 Feed opening depth 5 Stroke 2 Moving jaw 6 Nip angle 3 Stationary jaw 7 Feed opening width 4 Closed side setting

The IMS difference IMS Engineering offers its customers an extensive range of application specific solutions that are adapted to suit international mining and materials processing conditions These applications include crushing briquetting and compaction separation and screening drying recycling and tube cleaning systems
1 Adopt Proper Nip Angle The nip angle means the included angle between movable jaw plate and fixed jaw plate According to calculation the max nip angle can reach to 32° but in the actual production the nip angle is generally between 18° 20° smaller than 25° If the nip angle is too large the raw materials in crushing cavity will be
For instance adding a curve to the jaw dies can raise the position of the material in the chamber which promotes improved crushing and liner wear with smaller feed sizes However increasing the curvature also increases the nip angle in the upper half of the chamber reducing the ability of the crusher to process large feed materials
Nip angle The nip angle is the angle between the fixed and movable jaw dies A nip angle that is too large reduces the capacity and increases the wear as the feed material grinds and gouges the jaw dies in an upwards direction during the compressive stroke of the pitman C Series jaw crusher basic concepts The jaw crusher is a compression
A review on the design and operations challenges of a single toggle jaw crusher is presented Strength and fracture toughness of the material to be crushed are intrinsic properties that determine the time and energy required to crush the material Economy of the crushing process is partly dependent on the angle of nip Productivity of the crusher can be improved
Optimal nip angle ensures excellent bite in the cavity The correct nip angle between the movable and fixed jaw dies ensures good bite and material flow down even with slippery feed material It also reduces wear on the jaw dies reducing operating costs With a good grip the jaw crusher can crush rocks efficiently
Non choking Jaw Plates When the non choking concave demonstrated its capabilities in the gyratory crusher it was only natural that the principle should be applied to the jaw crusher But inasmuch as the Blake type jaw is used very largely for primary breaking where maximum receiving opening is more often than not a controlling factor the
Compound profiled liners can increase nip angles for improved comminution Factors Affecting Jaw Crusher Wear The wear rate of jaw crusher wear liners is influenced by a variety of factors including the feed material characteristics crusher operating conditions and maintenance practices

A dynamic model of the working mechanism of a compound pendulum jaw crusher with clearance is established by the Lagrange multiplier method LMD based on the L N contact force model and modified
The angle of nip for large crushers varies between 21° and 24° average about 22° of being crushed can be regarded as rings or spirals of which a single section may be regarded as similar to that of a jaw crusher which is inclined at an angle θ to the horizontal The operation of a gyratory crusher involves only one half of its
Operating costs are reduced by a steeper nip angle that reduces wear and speeds up material flow down in the cavity High Production In All Kinds Of Operations The presence of a larger feed opening ensures increased material intake so that the rocks enter the jaw crusher s cavity without restrictions Protective Seals
