The jaw crusher is primarily a compression crusher, while the others operate primarily by the application of impact. 4.2. Design of Jaw Crushers. Jaw crushers are designed to impart an impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of hardened steel.
J45/J45R Jaw Crusher. The J45 and J45R high capacity jaw crushers feature a true 1140mm (45″) x 688mm (27″) jaw. With both level and load sensors the J45 ensures the most efficient material handling across applications. The J45 features a heavy duty bofar design and pan feeder chutes with steeper angles to reduce material sticking.
The speed of jaw crushers varies inversely with the size, and usually lies in the range of 100–350 rpm. The main criterion in determining the optimum speed is that particles must be given sufficient time to move down the crusher throat into a new position before being nipped again.
functioning Jaw crusher. Most of these components are discussed below. Moveable jaw stock The moveable jaw stock is the main moving part in a jaw crusher. It forms the moving side of the jaw, while the stationary or fixed jaw forms the other. It achieves its movement through the eccentric movement of the crusher main shaft. It is the back and
Working principle of small jaw crusher for sale. When the mini jaw crusher machine is working, the motor drives the eccentric shaft to rotate through the belt pulley, so that the movable jaw periodically approaches and leaves the fixed jaw, thereby squeezing, rubbing, and crushing the material, making the material from large to small, gradually decreasing, Until it is discharged from the

Attached figure shows a cross-section through a double toggle jaw crusher. All jaw crushers are rated according to their receiving areas, i.e. the width of the plates and the gape, which is the distance between the jaws at the feed opening. For example, 500x750mm jaw crusher has a width of 500 mm and a gape of 750 mm.
CT and CTHT series jaw crushers are available in three different size ranges designed to deliver efficient, reliable and economical production. Supplied as either single machines, or combined with other Trio® crushers, screens, washers or conveyors, we provide customisable solutions for both portable and modular plants. Our Trio

Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher’s two jaw; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds
The J50’s jaw speed leads to better reduction and material being processed faster through the crushing chamber. McCloskey International has a proven reputation for designing quality, best-in-class equipment and the J50 Crusher brings even more power and productivity together in one machine.
Minyu Jaw Crushers are configured for primary crushing of the hardest rock. Incoming material is crushed between the jaw crusher’s fixed die plate and movable die plate through advancing and retreating motions of the jaw crusher pitman arm. The Jaw Crusher main shaft bearing includes a dust seal with oil bath lubrication.
Jaw Capacity: 2 3/8" x 4". Drive Type: V-Belt Driven. RPM: 400. Capacity: 800 lbs. per hour. Crushers with motor include motor base and belt/flywheel guards. Crushers without motor do not include motor base or belt/flywheel guards. RECOMMENDED SPARE PARTS FOR NORMAL ONE (1) YEAR OPERATION FOR WD CRUSHER.

Figures under Maximum Horsepower are correct only for throw and pinion Rpm given above. When speed is reduced, Maximum Horsepower must also be reduced proportionately. Example: 42-65 crusher, 1 inch throw, 265 Hp at 497 Rpm. At 400 Rpm Maximum Hp = 265 x 400/497 = 213. Crusher Feed Opening To Power Shovel Dipper. CRUSHER FEED OPENING
Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of the proper machine difficult. Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw crusher.
of the jaw crushers is the factor of RPM and the size of the crusher. Demand for different sizes of crushed product differs from time to time. For example, when a major new road is built, demand will differ greatly from the time when normal building construction or road maintenance is carried out. The worst situation is
