When it comes to crushing with the horizontal shaft impactors, the blow bars are actually a most essential component. Whether you refer to hammers, breaker bars or impact hammers, you can obtain the most out of your impact crusher to your blow bars and also your capability to utilize them. Based on what you are planning to crush like limestone, asphalt or you are recycling concrete, the kind of blow bar you utilize matters a lot. It may also take you one day in order to replace your blow bars, but you can save your money and time to understand the right blow bars for your every job.
Also, the blow bars can impart the energy into material as well as quicken it into apron or curtain, which causes the crushing and smashing of material. Normally, the blow bars appear similar and the metallurgy will always isolate each of the major kinds of blow bars. From great chrome to hybrid, every blow bar has a particular use that wants to be selected depends on several unique variables such as tonnage, geology and feed size and so on. Regardless of what you are searching to crush, one of the below kinds of blow bars must suit your need.
When it comes to choosing the right blow bars for your impact crusher, below www.crusherparts.org are some important points need to be considered that includes:
Pick the machined blow bars
First of all, you have to pick the finest blow bars from the AMCAST. Of course, this is a most competitor blow bar coming from the excellent machine. You should also observe that there is a minor or no equipment left to a right of ridge. In many cases, the blow bars must be machined, where they contact a rotor or must simply be minimum straight and flat as well. In addition to, you must observe the gaps beneath a straight edge displaying light.
Understand the various blow bar models
Grade ‘C’: This is poor shape and has an average thickness of around four inches blow bar and 3 in-depth grooves that cause a low rating.
Grade ‘A’: This is an amazing shape and also larger than normal thickness blow bar of around 4.5 inches with the optimistic noses to place a blow bar.
Grade ‘C’: This is also a poor shape that has fewer than average thickness blow bar of around 3.4 inches with one in-depth groove and cause a bad rating.
Be cautious while selecting a medium chrome alloy
You have to be more cautious when you stipulate the medium chrome and also know what family of alloy is used. Commonly, they have a couple of alloy categories for the blow bars such as:
White iron that includes 15% chrome, which is medium chrome and 25% chrome, which is high chrome
Low chrome that is three to five per cent steel, which is a very hard alloy
Around 15% to 25% of white iron is mostly same alloys and their physical properties are almost similar. For instance, resistance to breakage
The white iron is more fragile than compared to low chrome martensitic steel
Whenever the customer requests for medium chrome, then they must always be cautious of medium chrome is not a halfway between the high chrome and low chrome. Also, it is very nearer to high chrome as well. Thus, the medium chrome is not for a common purpose blow bar and cannot even perform a work of both high chrome and low chrome.
Rather, it will perform at high chrome, but is available at greater risk of fracture, when compared to the small chrome applications and high and average chrome alloys that have high wear properties. However, you always want to remain away from the heavy duty applications such as big feed size for basic machine or very great feed rates. Even the ceramic can also be added to any of the alloys defined just above to fix this issue.
Apart from these, there are four main kinds of blow bars available such as low chrome, high chrome, medium chrome and hybrid chrome alloy. Therefore, these are all things to consider while choosing the right blow bars for your impact crusher job.
