A hydraulic jaw crusher is a type of jaw crusher that uses hydraulic pressure to crush materials. It has a movable jaw that is operated by an eccentric shaft, as well as a fixed jaw that is positioned opposite the movable jaw. The hydraulic system allows the jaw to open and close, providing a wider range of crushing settings.

2. Both the structure and working of a jaw crusher are quite simple. 3. The product size is quite small and can range up to millimetres. 4. Repair and maintenance of a jaw crusher are convenient and easy. 5. The reliability of a jaw crusher is significantly high. 6. The broken parts of the jaw crusher are easy to replace. Disadvantages of a Jaw ...

® C Series™ jaw crushers have proven to be reliable and productive in thousands of mining, quarrying, recycling and industrial applications with up to 11,000 jaw crusher installations since 1975. Developed to crush the hardest ores and rocks, jaw crushers also perform outstandingly with less demanding materials.

Introduction. 1. The distinctive feature of jaw crusher is the two plates which open and shut like animal jaws. The jaws are set at an acute angle to each other, and one jaw is pivoted so that it swings relative to the other fixed jaw. Material fed into the jaws is alternately nipped and released to fall further into the crushing chamber.

Columbia Steel offers more jaw crusher plate styles than any manufacturer in the industry. Each of these designs has been developed for a customer seeking improved jaw crusher performance, including: Improved production. More accurate product sizing. Better wear metal utilization and lower discard weight. Lower overall operating costs.

Registered. Jun 6, 2013. #11. Another way to look at it is you will be crushing up and cleaning 7+ acres of road/foundation/wherever the concrete came from. I'll guess you need 40KWh of electric per hour to run 50hp average all day, 8 hours, 10 cents a KWH, $32 a day, say $640 a month for 5 days at 8 hours.

It has a low noise, high efficiency, reasonable structure, stable and reliable (with overload protection device), low energy consumption characteristics of a wide range of applications.

alterations in the relative positions of stationary and swing jaws with respect to the vertical; the introduction of curved (non-choking) jaw plates. The original Blake crusher was de­signed with a vertical stationary jaw. Probably the first departure from this arrangement was an 84 X 66″ crusher, built in 1914.

The jaw crusher line is designed for the motor sizes listed in RPG and technical specifications. This means that for harder materials, the crusher will have to be operated …

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. The space at the bottom of the "V"-aligned jaw plates is the output gap that dictates the size of the crushed product from the jaw crusher.

Feeding for efficiency. Jaw crushers are routinely choke fed to maximize production capacity and ensure that particles are uniformly broken. This promotes stone-on-stone crushing, which breaks up flaky or …

For crushing extremely hard, tough materials extra strength can be built into the jaw crusher at less extra expense than in the gyratory. So-called "standard" designs, i.e., unreinforced, are usually more rugged than the standard design of gyratory. Advantages and Disadvantages. Neither machine is particularly well suited to handling …

The jaw crusher line is designed for the motor sizes listed in RPG and technical specifications. This means that for harder materials, the crusher will have to be operated at larger settings to avoid overload of drive and/or motor. Using oversized motors will lead to radically shorter crusher life and various mechanical problems.

Abstract. ASTM Standard Practice G 81-83 describes a laboratory procedure for determining the relative gouging abrasion resistance of materials in a jaw crusher.
