Tumblers, Crushers, and Surge Machines Serve a Variety of Purposes in the Manufacturing Process



From finishing machines to processing the new materials, tumbling drums are an essential part of many kinds of production processes. Tumblers, in fact, are an important part of various manufacturing processes. Available in different sizes and formats, tumblers allow manufacturing plants to smooth the rough edges of finished machinery processes.
A two compartment barrel mill, for instance, is designed for dry milling of construction materials of medium and low hardness. And while rotary speed can vary from 85 rpm to 1,200 rpm, most modern models can be customized with different sets of hammers that enable machines to work on many different kinds of materials. Based on the same principle as the small tumbling machines that rock collectors still use at home, industrial size tumblers can smooth the edges of all kinds of objects.
Consider some of these facts and figures about the way that surge machines, tumblers, crushers, and crumblers are used in a number of industries:

  • With approximately three parts media to one of parts to keep parts from impinging, the optimum load height for barrel loads is 50%.
  • The horizontal octagonal barrel is used almost exclusively during the dry tumbling process. This barrel sometimes uses a hardwood lining, called a metal skin, which can be replaced when necessary. A barrel that is 30″ in diameter by either 36″ or 42″ in length is considered standard.
  • Ideal for both recycling and food processing, rotary crushers are typically built with shaft impactors to create considerable force, and they can be calibrated for a size reduction ratio between 10:1 and 25:1.
  • Tumbling will take anywhere from six to 24 hours, depending on the amount of material to be removed from the parts that need to be tumbled.
  • Although they are generally at 28 to 32 RPM, barrel speeds in dry tumbling can vary.
  • Parts usually account for one-third of the total barrel load, and the number of parts which will fit safely into a barrel are determined by the barrel size, part size, the part’s fragility, and the shape and weight of the end result desired.

Purchasing and maintaining industrial equipment is an important part of many industries. Finding the right machinery, in fact, can help your company be more productive and efficient.
