Single-cylinder Cone Crusher

A cone crusher reduces the size of the bulky rocks, stones, ores, and other materials between the mantle and the concave by using a steady compression force.

With continuous improvement, the cone crusher has developed from the initial spring cone crusher (often referred to as Symons cone crusher) to the hydraulic cone crusher. Hydraulic cone crushers include single-cylinder hydraulic cone crushers and multi-cylinder hydraulic cone crushers. Ftmmachinery offers the above three types of cone crushers.

This article will introduce a single-cylinder cone crusher. The single-cylinder cone will be referred to as cone crusher for short in this article.

The Ftmmachinery single-cylinder cone crushers have won the favor of customers from industries like mining, recycling, and construction with its optimized performance, automation system, less downtime, easy maintenance, and dependable operation.

Features of Ftmmachinery single cylinder cone crushers

Optimized performance

The single cylinder cone crusher features a perfect combination of crusher speed, throw, crushing forces, and cavity design. This combination is renowned for providing higher capacity and superior end-product quality in all secondary, tertiary, and quaternary applications.

The adoption of a unique crushing chamber and interparticle crushing principle leads to superior product shape, high reduction ratio, and high capacity.

Automation system

The crusher automation system allows you to start or stop the equipment by using the start/stop button, to adapt key parameters based on your plant characteristics from the control room, to alert harmful conditions such as sudden changes in feed size, and parts that need to be replaced.

Less downtime

The hydraulic and lubricating system adopts double insurance control, which offers overload protection and good bearing lubrication.

An electronically controlled pressure relief valve is used to let the crusher pass tramp iron.

All these improvements ensure stable production with less downtime.

Easy maintenance

Ftmmachinery cone crushers are safe and easy to maintain. They have access from the top of the crusher to the main components, making maintenance easier and ensuring the safety of maintenance personnel.

Cone crusher parts

The inner parts of a single-cylinder cone crusher

The main parts of the cone crusher involve concave, mantle, bowl-type bearing, copper bush, main shaft, etc.

Main shaft

It is supported by self-aligning It is supported by a self-aligning bearing which is designed to cater to the eccentric movement generated by the swing shaft. The feed materials are crushed by an eccentric movement of the main shaft.

Eccentric drive and bushing

The eccentric movement generates from the lower eccentric bushing and the driving device located at the bottom of the main shaft.

The eccentric bushing is made of high-carbon steel with a bronze inner wear-resistant sleeve. It is possible to adjust the eccentric throw by installing sleeves of different sizes.

Concave

Concave is also known as the fixed cone because it is stationary in a single-cylinder cone crusher. It is made of new composite material with features of high anti-abrasion, high quality, reasonable prices, wide application field, etc.

Mantle

The cone crusher mantle is also known as the movable cone. When a single-cylinder cone crusher runs, the mantle closes to or leaves the surface of the concave to squeeze and crush materials.

Pinion and intermediate shaft assembly

The alloy steel pinion is mounted on the pinion drive shaft. The external motor pulley device provides power to the pinion shaft, and the pinion shaft rotates the main shaft through the pinion and crown gear device.

Big gear copper sleeve

The copper bush of the cone crusher is used for sliding. There is a straight copper bush inside the large gear assembly, and the whole clearance available is less than 5 mm.

The main shaft of the movable cone inserts the cone copper bush, creating a gap of about 3mm and a low of about 8mm. The gap can be measured by the thick fuse when installation.

Wearing parts of a cone crusher

The main wearing parts of the cone crusher are:

• Mantle
• Bowl lining
• Concave
• Feed cone
• Main frame liner
• Protection cone
• Bushing
• Pinions and gears
• Adjustment rings and bowls

After long-term work of a single-cylinder cone crusher, the wearing parts will inevitably wear out. It is necessary to know what the wearing parts are, and then do some regular repair and replacement to stabilize production and avoid unexpected downtime.

Cone crushers are suitable for all demanding crushing needs

Cone crushers are effective in crushing medium-hard to hard mineral rocks, stones, ores and other materials.

It can crush rocks and stones like granite, pebbles, limestone, basalt, quartzite, and gritstone to produce aggregate and sand.

It can crush ores like iron ore, copper ore, manganese ore, lithium ore, tin ore, and nickel ore so that useful mineral particles are released during grinding stage.

It can crush concrete, asphalt, bricks, and other construction wastes to produce recycled aggregate.

Therefore, cone crusher machines are favored in many industries.

The following are just some of the industries that favor cone crushers.

• Mining
• Quarrying
• Concrete Recycling
• Construction and Demolition Waste Recycling
• Sand & Gravel
• Aggregates

Cone crushers are suitable for multiple crushing stages

Due to the wide range of discharging size, for example, the discharging size range of Ftmmachinery cone crusher is 4-41mm, cone crusher is typically applied in secondary and tertiary stages, sometimes even quaternary stages.

Sometimes they can also be applied in the first crushing stage provided the material is small enough to fit through the feed opening.

Limitations of cone crushers

While cone rock crushers are quite versatile, the size of their feed opening limits them. They are unable to crusher material that's too large to fit through the feed opening. Therefore, it is vital that you know, as accurately as you can, the size distribution of the raw material, and the feed size of the cone crusher.

Cone crushers are ideal for all types of medium to hard mineral rocks and stones, but it doesn't do well with softer ones. In particular, moist or viscous materials such as clay or shale aren't suitable for cone crushers. Otherwise, they will jam the machine.
