Jaw Crusher Liner Plate Design & Profile Shapes. Straight Jaw Plates: A shows a diagram of a standard type of Blake crusher with regular or straight jaw plates. This type of plate has been the standard from the time of its inception, emulating, in this respect, the straight concaves in the gyratory machine.

Discover how does a jaw crusher work with our simple guide. Learn about the mechanics and operation of jaw crushers on our blog.

Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.

In the history of crushers, both chronologically, and by virtue of its standing in the field of heavy-duty crushing, the Blake jaw crusher stands first in the list. All of the large, heavy-duty primary crushers of the jaw type are built around the Blake principle which, for simplicity and brute strength, is unsurpassed by any mechanism thus far …

1.4 Crusher Size and Power rating: The size of a jaw crusher is usually expressed as gape x width. The common crusher types, sizes and their performance is summarized in Table 1.1.Currently, the dimension of the. largest Blake-type jaw crusher in use is 1600 mm x 2514 mm with motor ratings of 250-300. kW.

Double toggle movement jaw crushers like the Blake style (named for the inventor of the first successful mechanical jaw crusher, Eli Whitney Blake ), have long been the standard used for crushing hard and abrasive rocks, …

Eli Whitney Blake invented the first successful mechanical rock breaker, the Blake jaw crusher patented in 1858. Blake adopted a mechanical principle familiar to all students of mechanics, the powerful …

Blake crusher-the swing jaw is fixed at the upper position. Dodge crusher-the swing jaw is fixed at the lower position. Universal crusher-the swing jaw is fixed at an intermediate position. The type of jaw varies, which makes the different jaw crushers preferred for certain projects. For example, the Dodge crusher is used for laboratory ...

The Blake features a double toggle jaw crusher drive mechanism which gives relatively smaller movement at the receiving end of the chamber generating a powerful crushing action for large rock pieces. A refinement on the crusher illustrated is the use of a curved jaw plate on the swing jaw which renders the crusher non-choking.

Jaw crushers have been around for almost 175 years. All jaw crushers are distinguished by the presence of two plates, one of which is fixed and one that swings open and then closes, concurrently trapping and crushing material between the two surfaces. There are three types of jaw crushers: Blake, Dodge, and Universal.

Sizing a Small Jaw Crusher (Anti-Friction Bearings) Small Jaw Crushers (or the Blake Type) are an exceedingly strong, serviceable machine, widely used in milling operations, also for general crushing equipment and work. It is especially adapted to handling blocky ore requiring large jaw openings 3″, 4″, or 5″ in size.

6. INTRODUCTION: Crusher: A crusher is a machine designed to reduce large rocks into smaller rocks Blake Jaw Crusher: A crusher with one fixed jaw plate and one pivoted at the top so as to give the greatest movement on the smallest side. Motion is imparted to the lower end of the crushing jaw by toggle joint. 8.

Discover the most common types of jaw crushers used in the stone crushing industry, including single toggle, double toggle, Blake, and Dodge jaw crushers. Learn about their construction, working …

For a time the development of the jaw crushers closely followed the existing designs for Blake breakers. The heavy cast-iron frames were reinforced by strong longitudinal tie-bolts; in some instances they were made in sections to permit of easier handling, but the parts became so cumbersome that cast steel was used to reduce their …

This crusher is the finest of our lines of jaw crushers which we offer. Others include: Superior, Type "B" Blake, Fine-Reduction and Dodge — sizes, 4 by 6 to 84 by 66 inches. A reciprocating machine, the crushes material in a straight line between jaws — without grinding or rubbing surfaces.

The Blake features a double toggle jaw crusher drive mechanism which gives relatively smaller movement at the receiving end of the chamber generating a powerful crushing action for large rock pieces.

Blake Crushers are Jaw Crushers with a movable jaw pivoted at the top, giving greatest movement to the smallest lumps. The throw of Blake jaw crushers is determined by the hardness of the ore as well as the size of the machine. It may vary from d in for hard but friable ores to 3 in for resilient material.

Double toggle jaw crushers, however, are heavier and require much larger headroom than single toggle machines. They therefore are generally unsuitable for mobile operations.

The Big Bite jaw crusher (Kue-Ken Div, Process Technology Inc.) is a Blake double-toggle type in which the fulcrum pinion is positioned well over the center ofthe grinding chamber [Anon., Quarry Management, 18 (1), 25-7 (1991)]. This increases the throw at the top of the jaw opening, allowing it to better crush large rocks.

Jaw crushers include Superior, Type "B" Blake, Fine-Reduction, and Dodge — sizes, 4 by 6 to 84 by 66 inches. A reciprocating machine, the crushes material in a straight line between jaws — without grinding or rubbing surfaces.

Jaw crushers feed materials between fixed and reciprocating plates. Blake, swing, overhead eccentric and Dodge jaw crushers are some of the variations available.

Discover the most common types of jaw crushers used in the stone crushing industry, including single toggle, double toggle, Blake, and Dodge jaw crushers. Learn about their construction, working principles, advantages, and disadvantages to help you choose the right one for your mining or aggregate operations.
