What is toggle in jaw crusher?
What is toggle in jaw crusher?
One toggle plate goes from the bottom of the eccentric arm to the bottom of the swinging jaw, the other toggle plate goes from the opposite side of the bottom of the eccentric arm to a fixed point at the very back of the jaw crusher frame. Single Toggle Jaw Crusher. Double Toggle Jaw Crusher.
What’s the difference between a jaw crusher and a gyratory crusher?
The gyratory crusher is mainly used for coarse crushing of various hard material in the primary crushing stage, but it is not suitable for crushing viscous ore. Jaw crusher can crush high moisture, viscous ore, and not easily blocked.
What is nip angle in jaw crusher?
The nip angle is the angle at which the material, that passes through the crusher inlet to be crushed between the jaws can be gripped by the jaws without slipping. Generally, this value is between 18 and 24 degrees in primary jaw crushers, and between 22 and 28 degrees in secondary crushers.
What is reduction ratio of jaw crusher?
6-to-1
Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
How do you calculate jaw crusher capacity?
The capacity of a jaw crusher is given by the amount of crushed material passing the discharge opening per unit time. This is dependent on the area of the discharge opening, the properties of the rock, moisture, crusher throw, speed, nip angle, method of feeding and the amount of size reduction.
What is the working of jaw crusher?
All jaw crushers reduce large sized rocks, ore, or other material by a compression action. A fixed jaw, mounted in a V-shaped alignment, is the stationary breaking surface, while a movable, “swing” jaw exerts force on the feed material by pushing it against the stationary plate.
How gyratory crusher is advantageous over to jaw crusher?
Features of the Gyratory Crusher minimizes slabbing; makes for more cubical product. Shape of receiving openings favourable for slabby material. Cost of foundation will usually be lower than for the jaw crusher. Necessary safety guards are less extensive than for the jaw crusher.
What is gyratory crusher used for?
Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher.
What is the size of heavy duty jaw crusher?

What do you call the width of the receiving opening of a jaw crusher?
The size of the feed opening is referred to as the gape. The opening at the discharge end of the jaws is referred to as the set. Figure 4.1. Double-Toggle Jaw Crusher.
What is black jaw crusher?
The original crusher of jaw type. A crusher with one fixed jaw plate and one pivoted at the top so as to give the greatest movement on the smallest lump. Motion is imparted to the lower end of the crushing jaw by toggle joint operated by eccentric.
Which type of crusher is best?
Gyratory Crushers are an excellent choice for a primary crusher, as they can handle very hard and abrasive material. They are ideal for dry to slightly wet material but not sticky material. Gyratories are compression crushers primarily used for heavy mining and quarried materials in extremely high tonnage applications.
How does a gyratory crusher change side settings?
In the standard gyratory crusher this is accomplished very simply by increasing the thickness of the concaves at the top, and tapering them down toward the discharge; in the jaw crusher the change is generally made by inserting a wedge-shaped filler behind the liner plates on the movable jaw.
How is the open side of a crusher measured?
The open side setting is measured when the crusher is at rest. The setting is measured either top to top, or bottom to top, depending on the tooth profile of the jaw dies. Closed side setting (CSS) The closed side setting can be calculated by deducting the stroke from the OSS.
How big is the gap in a jaw crusher?
-Minimum gap setting of when the mantle bowl rotates within the crusher or moving plate is closest to the fixed plate in a jaw crusher (‘closed’ position) – Gyratory’s: typically 90 to 220mm -Secondary’s: typically 30-60mm -Tertiary’s/Scats: typically 8-20mm -Jaw Crushers: 80-150mm WWW.MINTAP.COM.AU5 Current CSS Measurement Techniques
What should the crushing angle be on a crusher?
Crushing angles may vary between the approximate limits of 22 and 30 degrees in a line of standard gyratory crushers. It is possible to use larger angles in the larger sizes of crushers because the greater weight of the individual pieces of material tends to minimize slipping.
