Mini cone crusher

Types of mini cone crushers

The mini cone crusher is a machine that uses gravitational forces and mechanical pressure to break down materials into finer particles. This type of crusher is widely used in the mining and metallurgical industries to process ores and rocks of various hardness into smaller pieces for further processing or extraction. Cone crushers are generally suitable for harder materials like granite or basalt, giving them an advantage over other types of crushers.

Mini cone crushers work by having the material drop into the space between the base of the machine and the head, where it is crushed by the hydraulic or spring mechanism. This crushing results in a more rounded product that is easier to handle or further refine than the original material. The crushed material then falls out of the machine through an area known as the discharge area. The size of the discharge area can be modified to change the size of the final product.

There are three main types of cone crushers:

• Standard cone crushers: These are the typical cone crushers found in many mines and quarries. They produce a high volume of cone-shaped stones and are usually used for secondary or tertiary crushing. One benefit of standard cone crushers is that they can be retrofitted to improve their efficiency and capacity.
• Mini or small cone crushers: These types of crushers are more suitable for small-scale operations that have a lower production requirement. They take up less space and use less energy, making them more cost-effective for smaller businesses. Their portability allows for easier movement around the working site compared to larger models.
• Portable cone crushers: Also referred to as mobile cone crushers, these are perhaps the most versatile types available. They integrate a cone crusher with a screen and feeder onto a single track-mounted chassis. This design allows for easy transportation between job sites, rapid setup, and flexibility in processing different kinds of materials at various locations.

Specification and maintenance of a mini cone crusher

• Power:

  The power of a mini cone crusher varies in wattage and kilowatt between 2.2 and 30 kw. Smaller power provides sufficient crushing power for small-scale operations, while larger power offers greater capacity for more extensive processing needs.

• Production capacity:

  A mini cone crusher has specific production capacities depending on its model and size. Generally, these crushers can process between 5 and 50 tons of material per hour.

• Crushing ratio:

  The crushing ratio of a mini cone crusher indicates the size reduction it achieves. This ratio measures the size of the feed material compared to the size of the crushed product. For instance, a cone crusher may have a crushing ratio of 4:1, meaning it can break down materials to a maximum size four times smaller.

• Feed opening size:

  A mini cone crusher's feed opening size determines the largest feed material it can accommodate. The size ranges from 100 mm to 400 mm. For example, a mini cone crusher with a 200 mm feed opening can process materials with a maximum dimension of up to 200 mm.

• Weight:

  The weight of a mini cone crusher affects its portability and installation requirements. These lightweight crushers typically weigh between 1,000 and 5,000 kg. For instance, a crusher that weighs 2,500 kg can be more easily transported to remote locations compared to larger, heavier models.

Proper maintenance ensures the longevity and optimal performance of a mini cone crusher. Here are some maintenance tips:

• Conduct daily inspections to identify signs of wear, damage, or leaks. Check for loose bolts, deformed screens, or damaged parts.
• Implement a weekly lubrication schedule. Apply grease to the bearing and sealing components to prevent overheating and reduce friction.
• Clean the machine regularly to remove built-up materials that could affect performance. Use high-pressure water to flush out the internal parts.
• Change the oil in the motor every three months to maintain proper functionality and prevent breakdowns.
• Replace worn parts, such as the mantle and concave, before they become too degraded and cause damage to other components.
• Ensure that the electrical connections are secure, and there are no exposed wires
• Check the crushing chamber periodically to ensure there are no blockages

Scenarios of mini cone crushers

Some specific industries and areas that use cone mini crushers are as follows.

• Landscaping companies

  Landscaping companies and other outdoor businesses may use mini crushers to break up larger stones so they can be used decoratively or in more compact sizes on patios, walkways, or garden pathways. This helps reduce waste and minimizes site debris.

• Shopping centers and other urban developments

  Mega crushers are heavy and impractical for urban developments; instead, mini cone crushers provide a more feasible option. These can handle small volumes of concrete, bricks, and asphalt that do require crushing on-site. Mini crushers also help to produce smaller-sized aggregate that is useful and easy to transport.

• Mining and exploration companies

  Mini crushers are widely used to prepare samples for further, more in-depth exploration and analysis. They are also used for primary processing of minerals directly at the mine site in remote locations. Their compact size and portability make them perfect for mini crushers to be physically moved close to the ore rather than the other way around.

• Small-scale recyclers

  Whether rural or urban, small-scale recycling operators have limited resources and need equipment that is affordable, reliable, and easy to use manually. Electric-powered mini crushers are the best option for all of these and other reasons, and they allow smaller recyclers to process their waste independently and economically.

• Construction sites and small contractors

  Small-sized cone crushers are very popular among small to medium-sized construction companies and contractors. They can be easily transported to various job sites as they are portable and compact. The on-site crushing they do saves both time and costs. Using mini crushers reduces construction delays and expenses because material supply is right where work is happening.

• Material testing laboratories

  These labs have strict specifications they must comply with when using machine testing equipment. Mini cone crushers must have precision engineering so as to produce a consistent particle size. They need to be able to crush a specific volume of material. The mini crusher in question needs to be able to process material with a known moisture content. Accurate and repeatable results are essential when using mini crushers in lab environments.

How to Choose Mini Cone Crushers

When selecting the right cone mini stone crusher machine, there are many features and specifications to consider. To help business buyers with their purchasing decisions, here is a summary table outlining key features and benefits along with their corresponding explanations.

Whether it's a portable or fixed model, the cone crusher's design allows it to crush stones of different sizes by applying high pressure. The machine does this by exerting force on the stone to break它 up into smaller parts or pieces. In the market, buyers will find different types of cone stone crushers such as mini, micro, and hydraulic.

Mini cone crushers are ideal for secondary and tertiary crushing in smaller production sets. At the same time, micro cone crushers are better suited for home-based or hobby projects. Overall, both of these types are more economical and offer lower operating costs when crushing smaller quantities of stones. Generally, the mini and micro crushers have a set capacity of anywhere from 30 to 250 tons per hour.

When buying these crushing machines in bulk, buyers should get familiarized with some marketing terms that will help them choose the right type of cone stone crusher for their use or customers' demands. For example, the term 'hydraulic adjustment' refers to a type of cone crusher that has an automatic system to adjust its settings. This machine can easily change its opening size to control the level of crushing and provide better adaptability to different kinds of stone materials without having manual interference. Another term buyers should know is 'inverse' which means that the shaft of the cone crusher will be turned in the opposite direction during the crushing process. The inverting movement provides a better rupture of rocks and stone materials. Additionally, it helps the machine to have an improved separation and classification process.
