Choosing the correct rock or stone crusher for your application requires some initial thought. At the end of the day, it really comes down to the geology of the product that needs crushing. Sandstone, limestone and granite all require different types of stone crusher machines. Mainly, you need to make the distinction between choosing an impact style or compression style machine.
By already knowing ahead of time how you’ll need to apply the machine and the type of material in use, it helps narrow down your options. It is also helpful to know just how abrasive a certain material is as well as how hard it may be to crush it. The liners of your chosen machine will wear out much faster if you choose to crush an abrasive material. For example, limestone contains a great deal of silica and is, therefore, seen as an abrasive material.
Compression Vs. Impact Crushers
Once you have a vague idea of the types of materials that will need crushing, the next step is determining the type of crushing machine you’ll need to use in Aimix Group. Cone and jaw crushers are seen as compression style crushing machines. Compression machines are usually employed for use with highly abrasive rocks. Less abrasive materials would do well with something along the lines of a vertical shaft impactor.
Certain plants may wish to purchase both types of machines to use with different products. Impact crushers are a great choice when the shape of the stone is an issue as using one will result in better cubicity. This is highly recommended for customers that already have stone crushers that work well with bulk orders but only produce elongated pieces. The introduction of an impact style crusher may make it easier to produce higher quality products.
Protecting Your Investment
Yet another feature to take into consideration is the ability to protect your machine during the long hours of labor. Jaw crushers, for example, often come equipped with something called a toggle plate. This almost works as a safety switch in case some type of foreign or uncrushable matter goes into the wrong chamber. Tramp relief systems are found on cone crushers as they are able to protect the system against uncrushable matter.
Jaw crushers are the least protected machines against metal waste. Should something unwanted make it into the feeder, it could be disastrous for the machine. It feeds directly from raw materials, therefore, it is also the most exposed.
New generation technology is often a hit and miss for many seasoned workers. Machines produced recently may appear harder to control, but they offer much better quality products and with a bit of knowledge and ingenuity, fine crushed matter is easily avoided.
It’s also worth noting that some machines are indeed cheaper than others. This, however, doesn’t mean that a more affordable option is a viable solution for what you’re crushing. You may end up ruining the machine or disappointing customers, in which case, investing in the machine you actually needed would have been much better.
