Construction machinery is an absolute necessity in our increasingly technological and expanding society. Having to do certain jobs by hand is just impossible, and without some of these machines, we would not have nearly as many infrastructures and construction-based developments in our civilization.
Tumbling drums are one of the most useful construction tools. The most popular barrel dimensions vary in diameter (18″ to 36″) and in length (18″ to 42″). Usually, the diameter is smaller than the length. Horizontal barrel speeds vary from 20 to 38 RPM, depending on the barrel size and the items to be tumbled. Depending upon the amount of material to be removed from the parts, tumbling will take anywhere from 6 to 24 hours. However, for dry tumbling, the horizontal octagonal barrel is used almost exclusively. This barrel sometimes has a metal skin, and a hardwood lining which can be replaced when necessary. A barrel that is 30″ in diameter by either 36″ or 42″ in length is considered standard. Tumblers provide a lot of assistance in everyday construction project settings and without them, our projects would take exponentially longer.
When it comes to barrels, the number of parts which will fit safely into a barrel will be determined by the barrel size, size of the part, the part’s fragility, shape and weight and the end result desired. Parts usually account for 1/3 of the total barrel load. Additionally, barrel load heights (parts and media) should not be less than 45% or more than 60% of capacity. Load heights between 40% and 45% produce more action but a poorer finish. Also, for barrel loads, the optimum load height is 50%, with approximately three parts media to one of parts to keep parts from impinging.
For heavy machinery such as tumblers and barrels, proper usage and maintenance is important. You can either rent or buy this equipment, but whichever option you choose, keeping up with proper and standard routine maintenance procedures is the best way to maximize and optimize the life of your heavy construction equipment and machinery.
