At present, the common hammers used in the crusher are high manganese steel hammer and forging hammer, both of these two hammerheads are with the shortage of short using cycle, not wear-resisting, high cost and low efficiency. Our company developed a new type alloy hammer: Combined the high chrome multielement alloy and medium carbon low alloy wear-resistant steel together, so the hammers are with high wear resistance and good toughness. Now our products have sold to hundreds of ore-dressing and sand plant all over the world. After long-team tracking service, Our company concluded: Our alloy hammers’ using life is almost 2-3 times longer than that of high manganese steel hammers, 3-5 times longer than that of the forged hammers. Therefore create considerable economic benefits and social benefits for the users.
Ⅰ. Product characteristics
The hammer has many advantages: the handle has good toughness, not easily broken; Rockwell hardness can be HRC 65-67, good abrasion resistance, long life and other advantages.
Ⅱ. The use of range
The product is mainly applied to the mining enterprises and gravel plant hammer crusher use.
1. the hammer thickness in two sizes: 55,65
2. model: L=200,220...... A total of 14 kinds (Each hammer are marked)
|Product servive life|
|Forged Hammer||45||alloy hammers' using life is almost 2-3 times longer than that of high manganese steel hammers, 3-5 times longer than that of the forged hammers.（Except for special cases).|
|High manganese steel hammer||55(after impact)|
|Double metal alloy hammer||65|
Ⅴ. Matters Needing Attention
1. Feed process to keep the size of raw material can not be too big, with a diameter of less than 100 millimeter advisable.
2. When the machine runs, the operator can not be absent without leave, so can discover problems and stop in time.
3. Check and exchange the hammer regularly and timely.
4. Strictly avoid all kinds of metal objects into the hammer crusher.
Ⅵ. Efficency & benefit
In practice, the use of double metaly alloy hammer reduce parts replacement frequency, reduce the labor intensity of works, improve the crushing machine efficiency, increase the safely coefficient of production, will directly improve users’ economic effect.
