Product introduction:https://www.lvssn.com/crusher/Roll-crusher.html


With the expansion of mining scale, the demand for sand and stone materials is increasing.The development trend of large hydraulic roll crusher is inevitable.Everyone in the use of hydraulic roll crusher, it is inevitable that some accidents will occur.Hydraulic roller crusher fault solution.
 



1. Hydraulic roller crusher technical parameters




Hydraulic roller crusher
 



(1) feed particle size




As the name implies, the feed size of the hydraulic roller crusher means that the feed mouth can bear the size of the material, the feed size unit is generally used "mm".The feed size of hydraulic roll crusher produced by Jiangsu LVSSN is ≤500mm.
 



(2) discharge particle size




Whether the discharge particle size reaches the standard mainly depends on whether the discharge size of the crushing equipment is within the user's requirements. Under normal circumstances, the discharge particle size of the hydraulic roller crusher is 0-5mm, which can completely meet the user's needs.
 



(3) processing capacity




Hydraulic roller crusher
 



The capacity of hydraulic roller crusher refers to the number of materials broken by the equipment per hour, different types of crushing equipment, the capacity of hydraulic roller crusher is different.For example, the processing capacity of common models is 50-80t per hour.
 



(4) motor power




The motor power is directly proportional to the handling capacity of the crushing equipment. The larger the motor power is, the larger the handling capacity of the roller crusher will be.
 



2. Solution of hydraulic roller crusher's shaft rotation but the roller skin does not rotate




Hydraulic roller crusher
 



(1) the hydraulic roller crusher is very likely to be the universal coupling of the gravel equipment crack or fracture caused by, hydraulic roller crusher, the occurrence of this situation is easy to let the bearing parts squeeze, and then pressure roller skin.To avoid this situation again, we use the roll crusher, to avoid the single face coupling bear too much torque.

(2) hydraulic roller crusher in the use of the process must pay attention to the use of lubricating oil, different parts of the degree of lubrication is not the same.Especially in the long production process, we must pay close attention to the consumption of shaft lubricating oil.

(3) processing technology, different processing machinery in the development of the required materials, low selection standards, heat treatment process is not the same.

In the assembly of the hydraulic roller crusher to have a good assembly habit, or there should be a strict system to ensure the normal assembly to ensure the quality of stability.Work, such as "assembly" hydraulic pressure on the roll crusher power-hungry, staff need to choose the ideal inner hole size of the bearing and the bearing of a match, select ideal clapboard and the corresponding parts of the inner hole size tolerance to cooperate, will be recorded in the fit tolerance of each parts, as the hydraulic profile of roll crusher, for future maintenance and accessories sales and so on all can be used as a reference.

Product introduction:https://www.cementepc.net/crusher/Impact-crusher.html


Impact crusher is the sand production line and the crushing line in common use of the crushing equipment, known for its product grain type, want to impact crusher long-term stable service for you, do a good job of equipment maintenance is very important.Replacement method of wearing parts of impact crusher.



impact crusher



When replacing wearing parts, open them first and put them on the shelf.Impact crusher adopts screw or hydraulic capping device.When using, first remove the connecting bolts between the racks, then both sides of the two people operate the handle on the flap device at the same time, slowly open the rear upper rack, replace the wearing parts, use the flap device again, repeat the above process, that is, close it and put it on the shelf.
 



In the impact crusher, the plate hammer and the impact plate are the main wearing parts. The following are the replacement and installation methods of the plate hammer and the impact plate:



 



1. Replace the plate hammer



impact crusher



When the plate hammer is worn to a certain extent, it should be adjusted or replaced in time to avoid damage of fasteners and other parts of the impact crusher.

Open the rear shelf with a screw or hydraulic flap.Turn the rotor by hand and transfer the board hammer that needs to be adjusted or replaced to the access door, then secure the rotor with a safety device.Remove the plate hammer positioning parts: first remove the positioning baffle of the impact crusher, loosen the bolt group, and remove the serial Numbers 2 and 3 in turn. Finally, use the holes at both ends of the hammer head to lift out the hammer head, turn it around, and then press the hammer head in turn.

Special attention should be paid to plate hammers of similar weight installed in relative positions to avoid unbalanced operation.Serious vibration will greatly affect the bearing life of impact crusher.The equipment is not working properly.

 



2. Replace the counter plate



Impact crusher impact plate



(1) after opening the upper frame, remove the nuts and bolts used to fix the impact liner, and replace the impact liner after the impact crusher wears out.If a new counter liner is installed, reverse the above steps.

(2) all adjustment liners should be opened and put on the shelf. All liners are allowed to be interchanged in areas with heavier wear and areas with lighter wear.When a piece of liner is worn out only on one side, it can rotate 90° or 180° and continue to be used. If the material is found to be overstocked on the counter rack and stuck on the counter rack, the washer and bolt pad can be used behind the counter rack lining on the side and the gap can be reduced to avoid this phenomenon.

Correct installation is the premise to ensure efficient production of impact crusher.After the installation is completed, it is necessary to check the impact crusher (whether there is any foreign body and material in the crusher, whether the fastener is firm, etc.) and test (empty load and load test) to ensure normal production can begin.
