What’s the Difference Between a Lump Crusher and Hammer Mill?

Posted on 9/11/20 9:00 AM

Hammer mills and lump breakers, also known as lump crushers, are machines used in material handling systems across a wide range of applications. Many industrial sectors require particle size reduction for the processing of material—minerals and mining, cosmetics and pharmaceuticals, agricultural and food manufacturing, pet foods and plastics, and so on. In processing material, particle size reduction may be necessary to increase the surface area of material, increase  dissolution or absorption rates, improve pneumatic conveyance, ...

Tolling Services Explained

Posted on 8/26/20 8:35 AM

Tolling services are often defined as a simple arrangement, where one company processes raw material or near-finished goods for another in return for a “toll” or fee. Industry wide, toll processing services are known by many names—toll manufacturing, contract processing, tolling, toll conversions, and even toll milling when it involves size reduction—but the service is essentially the same. For example, contract processing may involve a long-term service contract or agreement between two companies to further process material, where ...

How Centrifugal Sifters Work

Posted on 8/17/20 1:24 PM

Centrifugal sifters, also referred to as rotary sifters or rotary screeners, are a type of industrial screening machine used to process a wide range of free-flowing materials such as powders, agglomerates and granules. Able to perform high-capacity scalping and sifting for both large and small applications, centrifugal sifters are cost-effective, offer increased production efficiency and operate with less noise and vibration than other types of screens, making them ideal for scalping away oversized particles and for removing  foreign ...

Understanding the Working Principle of Hammer Mills

Posted on 6/15/20 9:00 AM

Industrial hammer mills are employed in particle reduction applications for processing material. Though machine designs vary, the basic hammer mill working principle remains the same—uniform size reduction of aggregate raw material is achieved by repeated blows with hammers mounted to a rotating shaft. Whether coffee beans or titanium, hammer mills can effectively grind, shred, shatter or pulverize any raw material to the desired outcome upon impact.
