How to effectively choose a hydraulic cone crusher

Cone crusher is one of the most widely used mining machinery and equipment. With the development of the market, there are many types of products at home and abroad, and the performance of each type of crusher is different. At present, spring cone crusher and hydraulic cone crusher are more commonly used. Hydraulic cone crusher mainly crushes stones by bending and extrusion. Unlike traditional cone crushers, it integrates a hydraulic protection system to achieve safe and efficient operation.

Hydraulic cone crusher can be divided into multi-cylinder and single-cylinder hydraulic cone crushers, which can be used to crush various medium and high hardness ores, such as common pebbles, river pebbles, granite, iron ore, quartz stone, etc., with simple post-maintenance and low operating costs. The finished products are widely used in construction, building materials, infrastructure, mineral processing, cement and other departments.

In addition to the differences in the structure of the main machine, components and wear-resistant parts, the main differences between multi-cylinder hydraulic cone crusher and single-cylinder hydraulic cone crusher are also reflected in the following aspects:

1. Different iron passing and cavity clearing methods

Multi-cylinder hydraulic cone crusher. When unbreakable foreign matter passes through the crushing chamber or the machine is overloaded for some reason, the hydraulic insurance system is used to implement insurance, the discharge port is enlarged, and the foreign matter is discharged from the crushing chamber. If foreign matter is stuck in the discharge port, the cavity cleaning system can be used to further enlarge the discharge port and discharge the foreign matter from the crushing chamber. Under the action of the hydraulic system, the discharge port is automatically reset and the machine resumes normal operation.

Single-cylinder hydraulic cone crusher. When passing iron, hydraulic oil is injected into the accumulator and the main shaft falls; after passing iron, the accumulator presses the oil back and the crusher operates normally. The hydraulic pump is also used when clearing the cavity.

2. Different ways to adjust the discharge port

Multi-cylinder hydraulic cone crusher. Adjust the adjustment cap through the hydraulic pusher or hydraulic motor, thereby driving the adjustment ring to rotate in the support sleeve (the fixed cone spiral rotates and moves up and down) to achieve the adjustment effect. The advantage of this adjustment method is that the discharge port is easy to lock.

Single-cylinder hydraulic cone crusher. During normal operation, the main shaft cylinder is filled with oil or discharged through the oil pump to move the main shaft up or down (the main shaft floats up and down) and adjust the size of the discharge port. This adjustment method may cause the discharge port to be difficult to lock when crushing hard ore.

3. Comparison of components that provide crushing force

Multi-cylinder hydraulic cone crusher. The main shaft of the multi-cylinder hydraulic cone crusher is short and thick, and its diameter can be designed to be very large. It stands directly on the frame (not in the eccentric sleeve), providing a higher bearing capacity. The eccentric sleeve directly drives the moving cone to provide crushing force.

Single-cylinder hydraulic cone crusher. The single-cylinder hydraulic cone crusher is similar to the spring cone crusher, so the main shaft and the moving cone are supported by the base, and the eccentric sleeve drives the main shaft to provide crushing force.

4. Comparison of lubrication systems

Multi-cylinder hydraulic cone crusher. After entering the machine from the oil hole at the bottom of the machine and reaching the middle of the main shaft, it is divided into three branches: the inner and outer surfaces of the eccentric sleeve, the middle oil hole of the main shaft reaches the ball bearing, and the large and small bevel gears are lubricated through the hole; the other oil enters from the hole on the transmission shaft frame to lubricate the transmission bearing, and its return oil also returns through the return oil hole at the bottom of the small bevel gear and the return oil hole on the dust cover.

Single-cylinder hydraulic cone crusher. Two oil inlets are used for oil filling. One inlet enters from the lower end of the main shaft to lubricate the spherical bearing, spherical bushing, frame bushing, main shaft bushing, and then lubricate the large and small bevel gears; the other inlet enters from the end of the transmission shaft to lubricate the transmission shaft bushing, and finally the two oils are discharged from the same oil outlet.5. Different applicable materials.

5. Different applicable materials

When crushing soft ores and weathered ores, the single-cylinder hydraulic cone crusher has the advantage of large throughput, while when crushing medium-hard and high-hard ores, the multi-cylinder hydraulic cone crusher performs better.

For the fine crushing of medium-hard and above ores, under the same specifications, the multi-cylinder cone crusher can produce more qualified products. Generally speaking, the higher the hardness of the rock, the greater the difference between the single-cylinder and multi-cylinder operating effects.

6. Use and maintenance

The top or side of the multi-cylinder cone crusher can be disassembled and assembled, and maintenance is quick and convenient. All parts can be disassembled and maintained from the top or side. The moving cone and the top cone are easy to disassemble and assemble, and there is no need to disassemble the frame or tighten the bolts, making daily replacement more convenient.

Single-cylinder cone crusher has simple structure, reliable performance, simple and compact structure, low failure rate and low production cost (the simpler the mechanical system structure, the lower the failure rate, the higher the reliability and the more stable the operation).

7.Advantages of multi-cylinder hydraulic cone crusher

Advantages:

(1). Multi-cylinder hydraulic cone crusher has partially upgraded and improved the performance of traditional spring cone crusher, and has a reasonable structure. It uses multi-cylinder hydraulic technology to make the crushing of the crusher larger. While ensuring the output meets the standard, the energy consumption is also controlled, and it is suitable for a large number of stones, especially for crushing stones with a hardness of no more than 300Mpa.

(2). Multi-cylinder hydraulic crusher has a special crushing chamber design, which greatly improves the production capacity. Semi-automatic hydraulic adjustment of the discharge port can effectively control the stone particle size, and the finished material can reach the required size, so it is more economical and practical to use.

(3). Multi-cylinder hydraulic cone crusher will use high-strength integral casting casing when manufacturing, and has iron protection, which is safe and reliable. No matter how hard the stone is, the equipment performance is very stable and has a long service life.

8. Advantages of sinhe body structure is simple, with fewer parts, and the design is more exquisite in appearance.

(1). The body structure is simple, with fewer parts, and the design is more exquisite in appearance.

(2). The manufacturing cost is low, and the price is lower than that of multi-cylinder hydraulic cone crusher.

(3). The equipment is easy to install and maintain. From a technical perspective, the single-cylinder hydraulic cone crusher has made technical improvements to the sliding bearing. The improved equipment can adapt to higher speeds, increase the swing speed of the main shaft, make the size of the finished material more in line with the requirements, and at the same time, the output is higher.

The above are some methods and introductions on how to choose a hydraulic cone crusher. For customers who actually want to buy a hydraulic cone crusher, you can refer to the performance listed above and the actual situation of the equipment to make a choice, so as to choose the right equipment and improve production efficiency.
