what are the different types of shredders? | bizfluent

There are several types of shredders, from very simple paper shredders to high-tech disintegrators and hammer mills. Paper shredders can be subdivided based on the size of the final shredded pieces. Home and small business applications generally use the simpler types of shredders, while larger corporations and government entities use more sophisticated shredders to protect highly sensitive information. Industrial companies use hammer mills and pierce-and-tear shredders to dispose of various materials, including cardboard.

The strip-cut shredder uses a rotating blade to cut paper into long strips. This is the simplest, and least secure, means of destroying documents, as the strips can be reassembled by someone with enough time and patience for the task. Different strip shredders result in different strip widths, from 3/8 inch to 1/16 inch. From a security standpoint, the narrower the strip, the more effective the shredding.

Also called "confetti shredders," cross-cut paper shredders use specially designed blades to slice paper into small squares or diamond shapes. These pieces range from 3/8 inch wide to 1/32 inch wide, in varying lengths. The smaller size of the pieces increases the security level of the shred. Cross-cut shredders are widely available and are relatively inexpensive, making them one of the most popular choices for small businesses and personal use.

The most secure of paper shredders, micro-cut shredders reduce paper into minuscule particles. The most secure (and most costly) can reduce a single sheet of paper to more than 12,000 pieces. These types of shredders are typically used by research facilities and government agencies to provide the best possible security in disposing of top-secret documents.

Disintegrators are heavy-duty shredding machines that use multiple blades to shred paper until the particles are small enough to pass through a sizing screen. Two blades are mounted in a fixed position, while two to five more blades are affixed to a rotating drum in the center of the machine. Some disintegrator models can shred CDs, DVDs and other optical media, as well as tape and USB flash drives.

Hammer mills are similar to disintegrators. Rotating hammers pulverize the paper (or other material) and pass it through a sizing screen to achieve the highest level of destruction. The hammers may have knife blades, blunt edges or a combination of the two. Users can change the screen size to fit their particular needs. With the right screen in place, a hammer mill can reduce paper to dust.

Used primarily in industrial applications, pierce-and-tear shredders use multiple rotating blades that punch holes in the material being shredded, and then rip the material into tiny pieces. Most mobile shredding companies use a truck that incorporates pierce-and-tear technology and a large holding bin for the shredded material. Pierce-and-tear shredding is also widely used in industrial and manufacturing operations, to dispose of cardboard and specialty papers like newsprint.

hammer mills vs. roller mills: what's better for your business - halverson

When supplying feed to your livestock, youll need to choose between two types of feed mills: hammer mills and roller mills. Both types of milling come with their fair share of pros and cons and making the right decision for your business all depends on the types of animals youre raising. Different animals require certain types of feed for optimal conversion. For example, cows have large, complicated digestive systems, which means they require coarser particles that are high in fiber. While pigs have much simpler digestive systems, which require finer particles, but if these particles are too fine, some animals may develop ulcers.

Hammer mills use collision force to break up the feed. As the feed enters the chamber, particles bounce off the hammer plates until they are fine enough to exit through the screen. Generally speaking, the faster the hammer tip speed, the finer the particles. Hammer mills generally have much higher throughput rates than roller mills, so you can produce more feed in less time. Thanks to their simple design, hammer mills are also considered easy to maintain. They can be used to produce various types of feed, so you can create the right type of feed particles for all your animals.

However, hammer mills tend to have wide particle distribution rates, which means your feed may vary in size and shape. They also tend to consume more power than roller mills, which can lead to performance issues, excess heat, friction, and even spontaneous explosions. You may need to invest in explosion protection when operating at high volumes.

Unlike hammer mills, roller mills use compression to break up the feed. As the source material enters the chamber, its struck by two roller pads that break up the feed into finer particles. Roller mills come with narrower particle distribution rates, helping you control the size and shape of your feed. They also consume less power and produce less heat and friction than hammer mills.

Yet, you cant use roller mills to grind up fiber. These machines also require a lot of capital upfront. They might have trouble breaking up larger particles, so you may need to break up your feed before putting it through the machine. Roller mills also tend to require a lot of maintenance, which can impact your bottom line.

There are clear differences between hammer mills and roller mills, but new milling technology is breaking down these barriers. If youre looking for a universal feed mill that gives you more control over the size and shape of your feed without generating excess heat and friction, we recommend the Buhler Multi-Impact Hammer Mill. Unlike traditional hammer mills, it uses cutting plates to break up the feed as it enters the chamber, so particles dont have to hit the hammers repeatedly before exiting through the screen. This reduces heat and friction, so you dont have to worry about explosions and high maintenance costs.
