PFW Series Impact Crusher (hydraulic)

Working of impact crusher

When materials enter the function zone plate hammer, high-speed rotation of the rotor plate hammer, the materials into the crushing cavity produce high speed impact and be broken, and has broken material along the tangent direction of high speed into the crushing chamber at the other end of the back plate, were broken again, and then back to the board from the back plate was back again broken hammer function area, material from big to small into one, two, three counter repeated crushing cavity. On the way back and forth, between material and impact each other. Because the material is plate hammer blow, the impact of the back plate and the collision between the material, material cracks, loose to pieces. When the particle size is less than a third the gaps between the back plate and plate hammer, which expelled.

Counterattack Working of impact crusherproduct common troubleshooting methods

• 1. Counterattack crusher equipment belt flip: belt wear, need to replace the triangle, because the belt lose assembly problem, need to adjust the belt pulley on the same plane, it is important to note that the triangle itself quality.
• 2. Counterattack crusher equipment discharging granularity is too big: hammer head wear, need to hammer the spare or replacement, the clearance between the back plate and hammer head is too big, generally is adjusted for 15 to 20 mm, the feed granularity is too large will affect discharging granularity.

• 3. The counterattack crusher equipment vibration anomalies: shows the material is too big, can check the size of the feed. Uneven wear, explain counterattack hammer head need to replace, rotor imbalance, need to adjust, basic processes improper, anchor bolt and reinforcement shall be checked.
• 4. Counterattack crusher equipment bearing heating: illustrate bearing oil shortage, should be timely come on, come on, of course, too much will make bearing heating, be sure to check the oil level when refueling, bearing damage, to timely replacement of the bearing cover too close, to adjust good bolt, elastic moderate is advisable.
