Types of used stone crusher plants for sale

A stone crusher is a machine designed to reduce large rocks into smaller stones, gravel, or rock dust. The earliest crushers were hand-held stones, and they have been used for various purposes over time. Some of the primary uses of stone crushers include the construction of roads, demolition, mining, and recycling of waste materials. Over the years, many different types of stone crushers have been developed to meet the diverse needs of users. These machines vary in terms of design, capacity, and application.

Some of the most common types of stone crushers include jaw crushers, cone crushers, impact crushers, and compound crushers. Jaw crushers are commonly used because they can crush all types of rocks, including soft to very hard materials. They come in different specifications and capacities, depending on the material to be crushed. The jaw crusher works by pressing the material between two surfaces, with one surface applying pressure to crush the material.

Impact crushers, on the other hand, use high-speed collision to break rocks. They are commonly used for sand and gravel mining to create railroad ballast and construction aggregates. Impact crushers are preferred when crushing materials with low silica content, such as limestone. They are not suitable for crushing materials, such as weathered shales, slags, or cinders.

Cone crushers are used to crush hard materials, such as granite, basalt, and iron ore. They are also used for secondary crushing of materials that have been crushed. Cone crushers use compression to crush the material between a moving piece and a stationary piece. Compound crushers are a combination of small jaw crushers and small hammer crushers. They are cost-effective because they are made of durable material but come at a low price. They can be used for both primary and secondary crushing.

There are also impact crushers and mobile crushers. Impact crushers use striking to crush material, while used mobile crushers are designed to move from one location to another. Used stone mobile crusher for sale can be used in a mining quarry, coal mining, ore crushing in a recycling yard, construction waste, and cement production.

Specification and maintenance of used stone crusher plants for sale

The specification of the used stone crusher plant for sale depends on the type of crusher it has, the feeding and discharging specifications, and the power and capacity of the crusher. For instance, the small scale jaw crusher has a feed opening size of 300*1300 mm and a feed opening size of 60*110 mm. The discharging size is usually between 10-40 mm. The processing power of the small scale jaw crusher is between 1-3t/h. It has a seven power of between 5.5 and 15 kw.

Generally, a jaw crusher is used for plants with small processing needs. Gyratory crushers are generally used for primary crushing, and they crush the stone between the metal surface and the bowl. These crushers have a capacity of up to 3,000 tons per hour, with a maximum feed opening of 2,050 and 5,100 mm and a closed side setting of 50-300 mm. Gyratory crushers usually have a power of 2000-3000 kw. The gyratory crushers are used for plants with high processing needs.

Hydraulic cone crushers are also used for secondary crushing of large stones. They are very similar to gyratory crushers, but they are smaller. The hydraulic cone crusher has a capacity of up to 260t/h and a maximum feed opening of 300 mm and a closed side setting of 3-50 mm. It has a power of up to 220 kw. Cone crushers are usually used for plants that have intermediate crushing needs. The maximum feed opening of the cone crusher is 299 mm, and the closed side setting is 3-38 mm. It has a power of 90-440 kw.

Regular maintenance will help the used stone crusher plant for sale last longer and maintain a high resale value. In addition to the specific safety measures mentioned above, operators should regularly check and replace the crusher parts to avoid equipment failure and personal injury. Some other maintenance tips include the following:

• Check the lubrication system regularly and ensure the proper lubrication of the crusher bearing. The lubrication of the bearing directly affects the service life and operation of the crusher, so the operator should regularly check the lubrication points and lubrication parts to ensure that the equipment is well lubricated.
• Check the tightness of the fastening parts regularly and ensure that they are not loose to ensure the stability of the equipment operation.
• Regularly check the wear and tear of the wearing parts and replace them in time. The wearing parts are easy to wear and tear, such as the crushing wall and concave of the cone crusher and the jaw plate and cheek plate of the jaw crusher. They should be replaced regularly to ensure efficient crushing.

How to Choose

When purchasing a used stone crusher plant for sale, there are several important factors to consider. These factors will enable the buyer to find the right model that will meet their production goals and maximize their return on investment

• Production capacity: The output of the plant is an essential factor to consider when choosing a stone crusher. The primary aim of purchasing a stone crusher is to produce the desired amount of material needed to meet the demands of customers. Depending on the scale of the project, the crusher should be able to handle a certain volume of material per hour. This factor will vary depending on the type of stone to be crushed and the hardness of the material.
• Crushing principle: A used stone crusher is usually built to crush large stones. The design of the machine will determine the type of rock it can handle. The most common types of stone crushers are jaw crushers, cone crushers, impact crushers, and compound crushers. Jaw crushers are generally used for primary crushing because of their large feed opening and high crushing ratio. They are also effective in crushing hard materials. Cone crushers are usually used for secondary or tertiary crushing because they can crush stones of different shapes and sizes. They can be used to crush materials of medium hardness. Compound crushers are ideal for crushing materials with low hardness. They are built for fine crushing. Impact crushers are suitable for crushing materials with high hardness. They use high-speed impact to crush materials.
• Operating cost: The operating cost of the stone crusher is another factor that buyers should consider, as it will have an impact on the overall profitability of the business. More expensive crushers will process more material, but they will also consume more power and produce more dust than smaller crushers. The cost of maintenance will also increase as the size of the machine increases.
• Crusher type and condition: Depending on the type of stone, the jaw crusher is usually the first choice for primary crushing. It is a heavy-duty machine designed to handle large stones. The cone crusher works better on hard and abrasive rocks. The buyer of the crusher should ensure that the machine is well maintained so that it can provide efficient and reliable performance. Look for signs of wear and tear, such as cracks, holes, or loose components. Inspect the condition of the engine and electrical components to ensure they are in good working order. Make sure the safety devices are working properly. Safety devices help prevent accidents and protect employees from injury.
