PF Impact Crusher

PF Series Impact Crusher For Secondary Crushing

SBM PF series impact crusher is widely applied in mining, transportation, energy, construction and chemical industry. They are ideal equipment for crushing and screening. In a stone processing line, PF impact crusher is generally used as secondary crushing equipment. This machine features reasonable structure, high productsivity, easy operation and maintenance and safe performance. The most outstanding advantage of this machine is that its finished particles are in good, cubic shape and without tensility and cranny. Service online

Detailed introduction

  • 6. Easy to disassembly and maintain.

Working principles and applications

The main parts of the PF series impact crusher are rear case, impact plate, impact rack, chassis, blow bar and rotor etc.

This machine crushes materials with impact force. When the materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crushing. Then the materials will be shot back to the blow bar again for the third crushing. This process repeats until all the materials are crushed to the required size and discharged from the lower part of the machine.

Impact crusher the use of the scope

Impact crusher is mainly applied to mining, construction, chemical, power, metallurgical and other industries, broken compressive strength of not more than 300MPa of ore and limestone, slag, coke, coal and so on. Impact crusher should not be used to indicate that the water is greater than 8-10% of the ore or sticky material broken.

Maintenance and maintenance of the impact crusher

In order to ensure the normal work of the impact crusher and extend the service life of the impact crusher, the user should carry on the regular maintenance and the maintenance.

  • 1, check

    (1), the impact crusher should be smooth operation, when the impact crusher suddenly increased the amount of vibration, should immediately stop to identify the cause and eliminate it.

    (2), under normal circumstances, the bearing temperature should not exceed 30 ℃, the maximum temperature does not exceed 70 ℃, such as more than 70 ℃, should immediately stop to identify the cause and eliminate it.

    (3), plate hammer wear limit to the limit should be promptly treated.

    A, the first assembly of the plate hammer to reach the wear limit should be turned to upgrade.

    B, turn to upgrade, (the second assembly) to wear the limit should be replaced when the plate hammer.

    (4), plate hammer replacement, the use of the rotor brake device.

    When the rotor is working normally, the brake pin is screwed into the shroud. When the rotor is repaired and the plate hammer is replaced, the brake pin is twisted out, and then the pin is inserted into the screw hole and the tooth groove.

    (5), after assembly or replacement of plate hammer, you must ensure that the rotor static balance, the unbalanced amount of not more than 0.25kg.m.

    (6), when the liner wear, should be replaced in time to avoid wear the chassis.

    (7), before each boot to check all the bolts should be tightened.

  • 2, after the cover or box opening and closing

    When the rack liner, counter-liner, plate hammer and other wearing parts need to be replaced after wearing, or the impact crusher needs to be eliminated, in addition to PF-1007A, are used cylinder, expansion device or user-owned manual gourd Device, to open the cover or rear box, for replacement and maintenance.

    (1), open

    Before opening the top cover or rear case, remove the connecting nuts and bolts first, and then place the pad on the lower end of the upper cover arm. Open, the use of fuel tank open, only one person to operate the manual valve can be, until the cover or the rear box to open the dead end position; when using the expansion device or manual hoist open, you need two simultaneous operation of the expansion device Or manual hoist, until the cover or rear box open, when open close to the end, the lower pad should be pre-contact with the lower end of the arm slope to ensure safe and secure.

    (2), closed

    After a complete replacement or overhaul, turn the manual valve or 2 at the same time to operate the expansion or manual hoist to close the cover or rear case.


    A, before closing the cover or rear case, its contact indicates the need for thorough cleaning;

    B, in the open, close the cover or the rear box, the two movement direction is strictly prohibited, the opening of the end of the arm must be a good pad, and ensure a solid and reliable, absolutely safe before the other work.

  • 3, lubrication

    (1), often pay attention to and timely to do the friction surface lubrication work.

    (2), the impact crusher used by the grease, should be based on the use of the impact crusher location, climate and other conditions to decide, generally use No. 3 lithium grease.

    (3), every 8 hours after the work of the grease filling the grease once every three months to change the grease once, change the oil when the application of clean gasoline or kerosene carefully clean the bearings, adding grease to the bearing for its volume Of 1/3-1/2.
