Jaw crusher product advantages and working principle

Jaw crusher for short, is my company at home and abroad similar products in the successful experience of painstaking research out of an efficient, energy-saving equipment broken. One large and medium-sized jaw crusher is one of my company's products, especially in the design and production of large jaw crusher, at home and abroad have been in the absolute leading level. Mainly used for a variety of ore and large pieces of material of medium size crushing, crushing compressive strength of not more than 320Mpa materials, sub-broken and fine broken two. The series of complete product specifications, the feed particle size of 125mm ~ 750mm, is the primary broken preferred equipment. Jaw crusher (jaw broken) is widely used in mining, metallurgy, building materials, roads, railways, water conservancy and chemical and other industries.

Jaw crusher product advantages and working principle

Jaw crusher four characteristics:
1, unique jaw head structure, seal to ensure that extend bearing life; unique flywheel design, reduce vibration, the machine runs more smoothly.
2, gasket-type discharge port adjustment device, reliable and convenient, a large adjustment range, an increase of equipment flexibility.
3, the crushing chamber deep and no dead zone, increased feed capacity and production, the crushing ratio, product size uniformity; new oil design, supporting the use of pumps, operation and maintenance easier and more efficient.
4, using the overall casting, the use of new assembly process, so that with the frame to the perfect, increase the radial strength.
Jaw crusher work, the motor through the pulley drive eccentric shaft rotation, so that moving jaw cyclical approach, leaving the fixed jaw, so that the material is squeezed, rubbing, grinding and other multiple crushing, the material from small to big, Until discharged from the discharge port.

Commonly used jaw crusher type
Jaw crusher about hundreds of species, but the nature of its movement is not beyond the simple pendulum and complex pendulum two. The former is mostly made large or medium, crushing ratio of 3-6. Jaw crusher in the United States in 1858, nearly 130 years of development is particularly rapid, a variety of new products continue to emerge, such as: BLM negative support jaw crusher; KUE-type crusher; BUI-type inertia impact jaw crusher; Zero suspension single-toggle plate jaw crusher. These products are widely used in modern cutting-edge technology, such as: cavity-type computer optimization design; hydraulic control technology; sliding bearing to rolling bearing; hydraulic bearing and overload protection; reduced eccentricity increased oscillation frequency to achieve crushing; Product size in order to achieve a large crushing ratio, change the way suspension and support to change the jaw movement state to improve the ability to reduce wear and so on.

Working principle and operational considerations
When the crusher works, the electric motor drives the eccentric shaft through the pulley to make the moving jaw close periodically, leaving the fixed jaw, so as to squeeze, rub and crush the material. The material is gradually reduced and gradually descended until From the discharge port discharge.
As the performance of the machine (negative support, zero suspension) and mechanical structure constraints, the design uses a single, double jaw jaw inlay structure, making the machine structure is very compact.
(1) Adjustment of discharge opening: The width of discharge hole of double-jaw double jaw jaw crusher can be adjusted according to user's needs at any time. By adjusting the position of bracket (with two pairs of bolts on the side of the machine) Adjust the gasket placed behind the bracket, and then relax the top of the bolt to get the desired discharge port size, discharge openings of the adjustment range of 5-30mm.
(2) feed adjustment device: the upper part of the machine set up a hopper, in the middle of which is set with a feed adjustment baffle. This baffle can be adjusted to the main and crushing chamber side, and the effect is to control the feed rate in the two crushing chambers by the angle of inclination of the plate.
(3) the return spring: the machine design using a single, double jaw jaw inlaid structure, compared with the traditional crusher in the structure is completely different, the reset spring set by its structural constraints, can only use the current In the rear of the two moving jaws in the middle of the tension spring in the form of its pre-tightened.
 (4) overload protection: dual-chamber double jaw jaw crusher overload protection design of the traditional negative support jaw crusher structure, bracket bracket and frame for the body, bracket to the bracket in the rack And move the jaw, so as to play the role of overload protection.
