A double toggle jaw crusher is much larger, heavier, more moving parts and lower throughput than modern single toggle jaw crushers.The lower throughput statement is a bit misleading because it's partially attributed to the type of bearings they have versus modern crushers, so if one was to upgrade the bearings, throughput could be closer to that of a …
The size of a jaw crusher is usually described by the gape and the width, expressed as gape × width. The common crusher types, sizes and their performance are summarised in Table 4.1. Currently, the dimensions of the largest Blake-type jaw crusher in use are 1600 mm × 2514 mm with motor ratings of 250–300 kW.
They therefore are generally unsuitable for mobile operations. To add to that, they accept smaller feed size and have a much lower throughput. They are also prone to choking and bridging while crushing. In contrast, single toggle jaw crushers have fewer moving parts and aggressive crushing strokes. Being technologically superior, they have ...

Air-dried limestone was crushed continuously in a laboratory single-toggle Blake jaw crusher designed to provide a throw of 228 mm. The lower opening close set was 102 mm and the maximum bottom opening was 330 mm. The gape was 813 mm and the width of hopper 1067 mm.90% of the ore commenced crushing 200 mm from the bottom of the crusher.
Moreover, the wear of the jaw liner profile lowers the crusher performance by affecting the shape and the overall size of the crushed particles [12, 13]. Warping and wear of the jaw plate cause a ...

A single toggle Blake jaw crusher with 22.8 cm × 47.7 cm receiving hopper crushed gold ore at the rate of 85 t/h with closed setting at 2.54 cm and maximum opening of 3.8 cm. The work index of the ore was 13.5 kWh/t. ... The lower opening close set was 102 mm and the maximum bottom opening was 330 mm. The gape was 813 mm and the width of ...
This is because the Blake Jaw Crusher integrated a key mechanical principle – the toggle linkage – a concept students of mechanics are familiar with. ... The crushed material is first broken down at the top of the cone where they then fall down into a lower part of the cone that is more narrow. At this point the cone crusher crushes the ...
Double Toggle jaw crushers may feature hydraulic toggle adjusting mechanisms. Types. There are 3 types of jaw crushers according to the place the movable plate has been fixed around which position the rotates the movable jaw. Blake Crushers-fixed in the lower point; Dodge Crushers-fixed in the upper point; Universal Crushers-fixed in the mid point
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.
A critical point in the operation of large jaw crushers is the arrangement of the swing jaw and its supporting shaft. While in most crushers the jaw is pressed on the shaft and the latter swings in frame, in the jaw crusher the opposite principle is used—shaft is clamped in frame and jaw swings on the shaft! Another point has been lubrication.
The harder the material, the longer it may take to crush. In addition to production times the degree of hardness will influence the specific crusher for the operation. JAW CRUSHERS Jaw crushers, which use a …
J6 Jaw Crusher Designed to withstand the toughest conditions worldwide, the J6 delivers high TPH due to its innovative jaw chamber design and enhanced material flow. The large, deep chamber has proven to be particularly effective in hard rock applications, with an optional factory-fit rock hammer available.
Types of Jaw Crushers. Jaw crushers have been around for nearly 200 years at this point and are one of the most "historic" crusher types. Because of this, jaw crushers have advanced technologically through the years to make them more durable and to improve their movement to reduce choking and increase operational speed.
There are two main types of jaw crushers: simple-toggle and double-toggle. A single-toggle jaw crusher is simpler in design and is widely used because of its low cost and ease of maintenance. On the one hand, the double-toggle jaw crushers have a more complicated mechanism that creates a more uniform product size and a more efficient crushing.
The Blake crusher was first patented by Eli Whitney Blake in 1858 and it is the most common type of jaw crusher employed today. The Blake type jaw crusher has a fixed feed area and a variable discharge area. Blake type crushers …
