Crawler Mobile Jaw Crusher. MECRU crawler jaw crusher is suitable for all the natural stones as primary crusher. This plant adopts crawler chassis with fully hydraulic drive, high-reduction-ratio jaw crusher, feeder and vibrating feeder and such auxiliary machines to make an integrated crushing plant to solve the primary crushing problem.

Jaw crushers process medium to hard quarry rock or other materials by compressing it between the fixed jaw and the swing jaw. The swing jaw being the moving part is attached to a rotating eccentric shaft. The fixed jaw is an integral part of the crusher frame. Both jaws are fitted with manganese jaw liners that can be replaced or reversed when worn.

Primary Impact Crusher vs. Heavy-Duty Jaw Crusher. ...

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.

be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-

The models allow for the selection of a jaw crusher based on the nature of the rock being broken and the average amount of size reduction done on the feed material. The models can also be used to optimize feed and operational settings, as well to determine the product size produced for a given rock and reduction ratio.

Dec 08, 2009· TYPES OF JAW CRUSHERS In the dodge jaw crusher the moving jaw is pivoted at the bottom. As minimum movement is at the bottom it has a greater tendency to choke. In the Blake or jaw crusher the moveable jaw is pivoted at top.

of the theoretical value due to voids between particles and loss of speed in gripping the feed particle [4], [5]. Thus the actual capacity, Q = .356 t/hr 2.1.9 Crushing Power The required crushing power is a function of Bond work index, capacity and the reduction ratio. Adopting Gupta and Yan [5] the power is given by, P = Q.R d.w

Feb 25, 2015· Roll Crusher • The reduction ratio and efficiency of roll crusher is very low. • The main advantage associated with roll crushers is small proportion of fines produced and more uniform size of product crushed, than the other crushers. • Low capacity • Low reduction ratio = F/P • Sensitive to top size 2/25/2015 6:58:05 AM 38 39.

The Blake crusher was patented by Eli Whitney Blake in 1858. The Blake type jaw crusher has a fixed feed area and a variable discharge area. Blake crushers are of two types- single toggle and double toggle jaw crushers. In the single toggle jaw crushers, the swing jaw is suspended on the eccentric shaft which leads to a much more compact design ...

two crushing jaws. The moving jaw of the single toggle jaw crusher moves elliptically. A pendulum motion is being carried out by the double toggle jaw crusher. The crushing force is produced by an eccentric shaft. Then it is transferred to the crushing zone via a toggle plate system and supported by the back wall of the housing of the machine ...

Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

Rock Crushing Theory and Formula using Kick & Rittinger's Law. ... since the volume-reduction ratio is the same in both cases, the ratio of energy would be 1 to 1.
