The Ultimate Guide to Cone Crushers

Cone crushers are vital in the second stage of the crushing process in industries such as mining, construction, aggregate, and recycling.

This blog will examine the working principles and specific applications of the Lippmann 200C, Lippmann 300C, and the Lippmann 400C cone crushers to help you understand the importance of knowing how they work and how to choose the right one.

What is a Cone Crusher?

Cone crushers are heavy duty secondary crushing machines designed to withstand the strains that a quarry environment brings. It’s important to load a cone crusher with the correct size of material. Larger materials will be passed through a primary crusher first, which will feed directly into a cone crusher, creating a train.

How do Cone Crushers Work?           

• The Mantle: Inside a cone crusher there is a steel, cone-shaped moving part, this is called the mantle. This rotates and swings, constantly altering the gap between the mantle and the concave.
• The Concave: The concave is a fixed ring outside of the mantle. As material is fed into the machine, the mantle forces, with an incredible amount of strength, the material against the concave whilst it gyrates, inevitably crushing the material.
• The Sides of a Crusher: A cone crusher has two sides: an open side and a closed side. As the mantle gyrates, it creates a narrow point and a wide point. The distance of the wide side is known as the OSS (open side setting) and the distance of the narrowest point is called the CSS (closed side setting). Depending on how the OSS is set, it determines the size of the material produced. Any material that is small enough to fit through the open side will fall through the space between the mantle and the concave.
• The Motor : The motor is what drives the mantle and allows crushing to take place. Lippmann’s cone crusher motors are immensely powerful and capable of generating a significant amount power that material processing requires. The range varies from 360Hp to 612Hp.
• The Eccentric throw: The eccentric throw measures how far the mantle moves away from the centre of the crushing chamber, therefore defining how fast material will fall through the machine. If the eccentric throw is large, then the mantle will move further away from the concave, allowing material to fall through the machine at a faster rate as there’s more space for it to drop.
• Feed opening : The feed opening of Lippmann cone crushers are large and funnel-shaped, designed to process a variety of materials differing in shape and size. The Lippmann range offers feed opening from 914mm to 1130mm.

What to Consider When Selecting a Cone Crusher.

• Material Hardness: You should first identify the hardness of the material you wish to process and consider the abrasiveness and moisture content. Harder materials require more crushing force, and so the power capacity of the machine would need to be greater.
• Feed Size: Depending on the amount of material you have to process, you need to ensure the machine’s feeder and feeder belt is of appropriate size for the material to enter the crushing chamber.
• Output Size: The hardness of the material you wish to process influences the final product size and quality. Utilising a primary crusher before a cone crusher would ensure the material is of an appropriate density to produce the end product to a high standard.

Cone Crusher Applications

• Mining and Quarrying: Cone crushers are used to refine and shape material after primary crushing, producing a smaller and more uniform product. In some cases cone crushers are used to achieve fine crushing, producing highly detailed and fine end products.

• Aggregates Production: Cone crushers are essential machines for producing aggregates for construction projects such as gravel and sand.

• Recycling: Cone crushers play a crucial role in recycling asphalt and concrete. They break down the older materials producing re-usable aggregates, reducing waste and conserving natural resources.

Cone Crushers vs. Jaw Crushers vs. Impact Crushers: When to Use Each

Jaw Crushers

Jaw crushers are used in the first stage of the crushing process and are primary crushers. They can process material down from 8 inch to 3-4inch. Their crushing chamber’s feature two jaws: one of which is fixed and the other moves. They can handle a wide range of materials such as rocks, ores, and other materials of varying hardness, making them an option for many different applications. Jaw crushers are simple to operate and maintain however, it can be difficult to control the size of the output.

Impact Crushers

Impact crushers are generally used as secondary crushing equipment after a primary crusher to produce medium-fine particles. The crushing chamber of an impact crusher features a drum system that hammers the material. They are significant in the recycling industry creating materials that can be used for garden pathing for example. Impact crushers have large crushing ratios and low units of power consumption but the material being processed has to be soft application chips to achieve full productivity.
