6 Types of Crushers

Crushing equipment is common in the construction, recycling, and mining industries. Crushers are available in a variety of sizes and crushing capacities, depending on the project. Understanding the different types of equipment can help you select the best machine for your needs when looking for crusher rentals. Here are six common types of crushers:

1. Jaw Crusher

Jaw crushers use pressure to reduce materials into small pieces. It breaks rocks along their lines of weakness to produce coarse materials. Jaw crushers do this by squeezing the rocks between two steel pieces called jaw plates. During crushing, one of the jaws moves while the other is stationary. The gap setting between jaw plates determines the size of discharged materials. Use a tighter setting if you want the crusher to produce smaller materials.

Jaw crushers can be helpful during the primary crushing stages, and they can prepare materials like granite stones for other processing stages or secondary crushing. The crusher can be used in the mining industry to crush rocks into smaller pieces for use in the construction industry.

2. Cone or Gyratory Crusher

Cone and gyratory crushers also use pressure to crush materials into smaller pieces. Like jaw crushers, they crush materials between two pieces of steel, with one piece moving and the other remaining stationary. Unlike a jaw crusher, cone and gyratory crushers can’t handle sticky materials. You can use these crushers for primary, secondary, and tertiary crushing processes.

Gyratory crushers are typically used to break down larger materials, and cone crushers are used for smaller materials. The crushers can be used in the mining industry to crush slabby rocks that a jaw crusher can’t handle due to its opening.

3. Impact Crusher 

Impact crushers use mass and velocity to break materials down. As materials enter the crusher, rotating blow bars or hammers reduce them into smaller pieces. The materials then come into contact with breaker plates that further break down the materials. 

Final products from impact crushers typically have a cubical shape. They can be ideal for the mining and recycling industry. You may use it to crush coal, limestone, and gypsum. 

4. Roller Crusher

A roller crusher breaks down stones between two parallel cylindrical rollers. The rollers move opposite each other as grinding happens continuously. You may use a roller crusher in mining to break materials with medium hardness, such as coal and limestone. 

5. Sizer

Sizers help to crush medium-hard materials during the primary stage of crushing. The materials placed into a sizer can be wet or dry. The sizer crushes materials using two inward-rotating rollers with teeth. Sizers can be ideal for use in the mining industry to crush hard rock minerals such as gold and copper. 

6. Grinding Mill

A grinding mill is a crusher commonly used in the agricultural industry. It uses compression methods to crush, grind, and cut the feed materials. Grinding mills help to crush soft materials such as grains. The grinding wheel breaks the materials into fine powder. 

Benefits of Renting Equipment Over Buying

Companies in the mining, recycling, and construction industries need different types of crushers. Jaw crushers, sizers, and roller crushers are some equipment you may require in the mining industry. You may not be able to afford to buy all the equipment you need for crushing, but crusher rentals can be a great alternative. Here are some of the benefits:

Forgo Initial Investment

You may need to invest a significant amount of capital to buy all the crushers you need for your business. If you don’t have enough money for an initial investment, you can consider renting over purchasing. It can save you money as it tends to be cheaper than purchasing.

Keep Low-maintenance

Renting equipment can also reduce your machine maintenance cost. If you purchase crushing equipment, you cover maintenance costs until you sell it. When you rent, the rental company will charge you maintenance costs for the period you use the crusher.

Avoid Storage Costs

Renting crushers can also help you avoid storage costs when they are not in use. When renting a crushing machine, storage costs can only apply when you’re using the equipment. After completing the job, the company you rent from becomes responsible for storage costs. 

Consider Crusher Rentals

Crusher rentals can be an ideal option if you are in the mining, recycling, and construction industry. Those operating in these industries require different crushers, such as jaw crushers, sizers, impact crushers, and roller crushers. Renting a crusher can save you and your company large sums of capital needed for initial investment.
