Crumblers and crushers provide many services, one of which includes cleaning and polishing of any number of products. Sometimes products or materials are separated among tumbling drums into different grades and then further processed to intermediate and finished products.

About Crushers and Tumbling Drums
Tumblers, crumblers, and crushers work under two primary categories: dry tumbling and wet tumbling. No matter which category it falls under, crumbling and tumbling can take up to a full day. It is important to make sure that the proper process is set up from the first step because the correct machine or tumbling drum needs to be chosen in order to make sure that the process will run properly from the beginning to the end.

Machine Requirements for Crushing and Tumbling
Dry tumbling most often requires the use of a horizontal octagonal barrel. This barrel may have metal skin and a hardwood lining, although this can be replaced whenever necessary. The barrel is usually 30 inches in diameter, along with a recommended length of 36 or 42 inches based upon the process that it will complete. Additionally, are standards required for the tumbling drums, different from the barrels. These tend to vary with a diameter ranging from 18 to 36 inches, and also have a varying length from 18 to 42 inches. Included in the standard is that the diameter tends to be smaller than the length, along with speeds ranging from 20 to 38 RPM. Choosing the crumblers or tumblers is most often based on the material to be processed.

Similar to processing mills and factories including food crushers and cement production, the processes of crumbling, crushing, and tumbling help separate many different materials. With various requirements that must be met during these processes, any of these processes may easily be left incomplete. It is important to make sure that the proper drums are used, along with the correct size of parts. Knowing the optimum load size for these processes is only about 50%, it is important to not overload any drum when completing this process. Crumbling and tumbling requires caution and preparation, along with a lot of expertise to make sure it is done well.
