Wear-Resistant Impact-Resistant Crusher Hammer Hammer Mill Accessories
Product Features
1. The impact force on the material is increased. Because the center of gravity of the hammer crusher's hammer moves outward in the radial direction of the gyration radius, the hammer's midline speed increases during operation. The impact work of the hammer crusher's hammer on the material is increased, thereby improving the crushing effect.
2. The effective wear of the hammer crusher's hammer is increased. The weight of the hammer is generally 27 kg, and the effective wear accounts for one-third, that is, 9 kg. The total weight of the improved structure changes little, and the effective wear reaches 16 kg. One set of hammers after the improvement is equivalent to two sets before the improvement, which reduces the cost of use.
3. The particle size of the discharge is reduced and the hourly output is increased. After the improvement, the length from the hanging hole to the end of the hammer is increased from 350 mm to 360 mm, the gyration diameter is about 1250 to 1270 mm, and the gap between the hammer crusher's hammer and the shell plate is reduced from 25 mm to 15 mm. Therefore, the output particle size can be changed from the original less than 20 mm, 25% powder to 8-10 mm, 60% powder, which greatly improves the crushing effect of the crusher, thereby increasing the hourly output.
Product Features
1. Forging heated metal materials into tools, mechanical parts or blanks of various shapes is called forging. Forging can change the internal structure of metal materials, refine the crystals, and improve their mechanical properties.
2. Forging production must use heating equipment, forging equipment and many auxiliary tools.
3. Forging equipment mainly includes steam hammer, air hammer, die forging hammer, mechanical hammer, clamp hammer, spring hammer, belt hammer, crank press, friction press, hydraulic press, reamer, roll forging machine, etc.
Product advantages
1. Ultra-high wear resistance → Stable discharge particle size, reduce replacement frequency
Material technology: High manganese steel alloy composite casting, surface hardness HRC58-62, impact wear resistance increased by more than 3 times, slow down the sinking speed of the hammer working surface, and ensure that the discharge particle size meets the standard for a long time (avoid the overload and breakage of the screen bar in fault 2);
Structural design: Stepped hammer arrangement + streamlined striking surface, reduce stone sliding friction, reduce 30% of invalid wear year-on-year, and extend the life to 8000-12000 hours.
2. Precise static balance design → Suppress vibration exceeding the standard and protect the bearing life
Manufacturing standard: Single hammer weight error ≤0.05%, supporting static balance calibration tool kit to ensure that the dynamic balance deviation of the rotor group is <0.2mm, reducing the risk of abnormal overheating of the bearing (eradicating the bearing overload caused by the vibration of fault 6);
Pre-assembly adaptation: According to the rotor model classification and numbering, support the purchase of complete sets of counterweights, and reduce the on-site manual calibration time by 80%.
3. Strengthening impact toughness → Preventing fracture and reducing unplanned downtime
Heat treatment process: vacuum carburizing + double liquid quenching, core hardness HRC45-50 and gradient transition with high hardness layer on the surface, hammer handle bending strength ≥850MPa, resistant to impact of high hardness materials such as granite/basalt (preventing internal impact caused by hammer head fracture in fault 5).
