From the food crusher to cement crushers, tumbling drums can be applied in a number of different ways, making the average tumbling drum crucial to many of the processes of the manufacturing world here in the United States. But though tumbling drums are incredibly useful for so many different applications, it is crucial that they are used correctly, as the tumbling drum used as a food crusher is likely going to operate much differently than a tumbling drum that is being used to polish plastic pieces.
For instance, the length of time that the tumbling drum is used will very much depend on the process. At the least, a tumbling drum will operate for no less than six hours. At the most, it can sometimes run for as many as 24 hours. However, a tumbling drum as a food crusher that runs for 24 hours is likely to have disastrous results, as well as vice versa for other processes for which the use of a tumbling drum is ideal.
In addition to the length of time that a tumbling drum is set to run, you must also consider the speed of the tumbling drum as well. However, the range of barrel speeds that are regularly put into use are much smaller than the range of time that theses barrels are spun at. At the very least, a barrel will be spun at a speed of 28 rpm. However, this speed will typically not need to exceed 32 rpm.
And even different sized and shaped barrels can be used in tumbling drums, something that many people might not actually realize. Typically, however, it is most common to see barrels with diameters that are smaller than the length of the barrel, with horizontal barrels having a wider range of use than other types of barrels. These barrels, for instance, can be spun at speeds that are as low as 20 rpm but as high as 38 rpm, making them ideal for a wide range of uses.
And it is very important to note, of course, that the size of the barrel very much impacts how much the barrel can be filled up. Ideally, the barrel load will not reach more than 60% capacity, giving the parts and pieces inside that space that they need. In many cases, it will even be ideal for the barrel load not to exceed a relatively low 45% capacity, though this is most definitely something that will need to be determined on a case by case basis.
There are a number of factors that will decide the capacity to which the barrel is filled. For instance, the size of the parts in question is key, as is their overall fragility. In addition to this, the shape and weight will also need be considered. Ultimately, it is the desired end result that will dictate how fully any given barrel on any given tumbling drum is filled.
Aside from the tumbling drum, rotary crushers like the food crusher are also frequently used. The food crusher is an important function of your typical rotary crusher, with the food crusher up there as one of its top uses. But rotary crushers serve a larger role than just as a food crusher and for food processing purposes, as they can actually also be hugely useful for recycling purposes as well. They are built with shaft impactors that are specifically designed to create a considerable force, making them more than ideal as a food crusher or crusher of recycling materials, with a size reduction ratio that varies between 10:1 and 25:1 – a wide range, to say the least.
And the speeds of the typical rotary crusher tend to be much higher than the speeds of the tumbling drum, as tumbling is a much gentler process and rotary crushing a much more forceful one. In fact, rotary crushers can even reach speeds of up to 1,200 rpm and typically don’t fall beneath speeds of 85 rpm. In many ways, this makes rotary crushers just as ideal for a wide variety of purposes as the tumbling drums used throughout the manufacturing industries, if not an even more versatile machine.
