Crushers are a piece of equipment used to reduce the size of aggregates. There is a range of types of crushers, and each is designed to meet the requirements of extremely specific applications or materials. The key factor with feed material is its degree of hardness. The hardness of the material is generally measured in terms of compressive strength, which is basically the maximum force that the material can tolerate before breaking. The hardness level will vary from that of concrete at 7000 psi to 50,000 psi for ores or other hard materials. But the harder the material the longer it will take to crush. The hardness also influences which specific crusher is required.
Types
Jaw Crusher
Jaw crushers are the archetypal crusher used for the dismantling of rock and stone, with a quarry jaw crusher you are able to crush all kinds of materials to various sizes depending on your requirements. The movable jaw applies force on the rock and forces it against the stationary plate, the rocks then remain between the jaws until the material is small enough to pass through the gap at the bottom of the jaws.
Cone Crusher
Cone crushers are compression machines that reduce materials by squeezing the rock between moving and fixed elements. Our used cone crushers at Omnia Machinery are able to be used as primary or secondary crushers.
Impact Crusher
Created to fill the space in the market left by cone and jaw crushers, impact crushers are perfectly suited to contaminated materials and can easily handle any clay, dirt, or metal mixed in with the feed material. There are three different types of primary impact crushers to pick from; horizontal shaft impactors, cage mill pulverisers and vertical shaft impactors, all of which you’ll find here at Omnia Machinery.
History
Crushers have played a critical part in the history of America. Since the mid-1800s there have been millions of tons of stone crushed to aid in the development of a vast range of structures, roads and everything you can imagine.
The first ever stone crusher was invented by Eli Whitney Blake, after five years, Blake’s stone crusher roared to life this was all due to the issue that plagued the town of Westville. Fed up with wagons getting stuck in the mud they decided to lay a rock surface on the road. Blake went further with the design and developed it for the railroads to create ballast.
Considerations
Cost – prices will always differ between types of heavy equipment, however at Omnia, we can supply you with different crushers that are affordable, efficient, and will give you the best value for money.
Features – The features of a crushing machine are fundamental when choosing the right tool for the job. While you may find a cheaper crusher, it may not have the specific features which can make a job a lot more convenient.
Type of stone material – it is important to know the type of material you may be crushing so you can clarify if the machine can process it correctly. The type of hammers you use in your crushing machinery will impact how efficiently it’s able to process the aggregates. specific hammers are more durable meaning they can crush all kinds of aggregates; however certain are only suitable for asphalt, or natural stone.
Mobility – If you require a crusher only for smaller scale tasks, then small materials and tools like a sledgehammer or a pry bar may already work. However, if the job needs to be carried out in larger-scale operations — such as in road asphalting, quarrying, and mining, then you must make sure the machine has a high level of mobility.
Quality – it goes without saying that you should always check any machine you purchase is of high quality, this is an investment you don’t want to mess up.
