Common troubleshooting methods of hammer crusher

Introduction and application of hammer crusher:

hammer crusher is suitable for crushing all kinds of medium hardness and brittle materials. The crushed materials are coal, cement, gypsum, alum, brick, tile, limestone, etc. the compressive strength of materials is not more than 300 MPa, and the humidity is not more than 15%. At present, hammer crusher is widely used as an ideal product for artificial sand making

working principle of hammer crusher if the advertisement sponsor still recommends and proves goods and services in the advertisement "knowing or should know" that the advertisement is false:

the main working part of hammer crusher is the rotor with hammer (also known as hammer head). The rotor is composed of the main shaft, disc, pin shaft and hammer if oil leakage is found. The motor drives the rotor to rotate at high speed in the crushing chamber. The materials enter the machine from the upper feeding port and are crushed by the impact, impact, shear and grinding of the high-speed hammer. At the lower part of the rotor, there is a sieve plate. The particle size smaller than the size of the sieve hole in the crushed materials is discharged through the sieve plate, and the coarse-grained materials larger than the size of the sieve hole are prevented from remaining on the sieve plate and continue to be hit and sheared by the hammer, and finally discharged out of the machine through the sieve plate

hammer crusher failure and Troubleshooting:

1. Bearing Overheating

cause: insufficient grease; Too much grease; The lubricating grease is dirty and deteriorated; The bearing is damaged

Troubleshooting: add an appropriate amount of grease; The grease in the bearing shall be 50% of its space volume; Clean the bearing; Replace the lubricating grease; Replace the bearing

how is the tensile test of polymer film done? 2. Discharge particles are too large

reason: the hammer head is worn too much; The screen bar is broken

Troubleshooting: replace the hammer; Replace the screen strip

3. Production reduction

reason: the gap of screen strip is blocked; Uneven feeding

Troubleshooting: stop the machine and clean up the blockage in the gap of the screen strip; Adjust the feeding mechanism

4. Knocking sound of elastic coupling

cause: loose pin shaft; The elastic ring is worn

Troubleshooting: stop and tighten the pin nut; Replace the elastic ring

5. Knocking sound inside the machine

reason: non broken objects enter the machine; The lining plate fastener is loose, and the hammer hits the lining plate; Hammer or other parts are broken

Spring change tester

Troubleshooting: stop the machine and clean the crushing chamber; Check the fastening of the lining plate and the gap between the hammer and the screen strip; Replace broken parts

6. Machine vibration

cause: the static balance of the rotor does not meet the requirements when replacing the hammer head or because the cone head is worn; The hammer head is broken and the rotor is unbalanced; The pin shaft is bent and broken; Triangular or circular plate cracks; Foundation bolts are loose

Troubleshooting: remove the hammer head, select the hammer head according to the weight, and make the total weight of the hammer on each hammer shaft equal to the total weight of the hammer on the opposite hammer shaft, that is, the static balance meets the requirements; Replace the hammer head; Replace the pin shaft; Electric welding repair or replacement; Tighten the anchor bolts
