CJ412 Jaw Crusher, Heavy Industry Preferences Applications

In the field of mineral mining and processing, the crusher plays a crucial role. It is mainly used for primary crushing of gold, iron ore, copper ore and other metal ores, during which the originally large raw ore blocks will be effectively crushed to a size suitable for subsequent grinding or transport. For example, in gold mining, large gold ores can be reduced to a size more suitable for entering the ball mill for fine grinding after processing by the crusher, thus substantially improving the processing efficiency and extraction purity of the ores. According to statistics, the use of advanced crusher can increase the crushing efficiency of the ore by more than 30%, significantly reducing production costs.
In addition, the crusher also performs well in processing granite, basalt, limestone and other hard rocks. After crushing and processing, these rocks can produce high-quality construction sand and gravel aggregates, which are indispensable basic materials for building large-scale projects such as highways, bridges and high-rise buildings. Taking the construction of highways as an example, high-quality sand and gravel aggregates can ensure the smoothness and durability of the road surface, and improve the service life of the road and driving safety. According to industry reports, the service life of highways using high-quality sand and gravel aggregates can be extended by more than 20%.
With the acceleration of urbanisation, the disposal of construction waste and concrete waste is becoming more and more prominent. The application of crusher in this field realises the effective crushing and reuse of these wastes, providing strong support for the recycling of resources. Through crushing, construction waste and concrete waste can be converted into recycled aggregates, which can be used to produce new building materials or lay road sub-base, thus realising the recycling of resources. It is estimated that globally, about hundreds of millions of tonnes of construction waste are reused through crushers every year, which not only reduces the pressure on the exploitation of natural resources, but also helps to reduce environmental pollution.
In addition, crusher is also widely used in the pre-treatment of raw materials in metallurgy, chemical industry and other industries. In these industries, the particle size of raw materials has an important impact on the subsequent production process and product quality. Therefore, the use of crusher pretreatment of raw materials can ensure that the particle size of raw materials in line with production requirements, improve production efficiency and product quality. For example, in the metallurgical industry, the crusher can crush iron ore to a particle size suitable for entering the blast furnace smelting, thus improving the utilisation factor of the blast furnace and the quality of the iron.

CJ412 Jaw Crusher, Heavy Industry Preferences Advantages

Highly efficient crushing performance

The crusher adopts an optimised deep chamber structure, which makes the internal space of the crushing chamber more reasonable and can accommodate and crush materials more effectively. At the same time, the high swing frequency design ensures that the crushing hammer or jaw can complete the crushing action of the material more quickly. The combination of these two makes the crusher's processing capacity significantly increased, compared with the traditional model, its processing capacity increased by more than 20%. This means the crusher can process more material in the same amount of time, resulting in higher productivity for the user.

Superior Durability

The movable and static jaw plates are the core components of the crusher, and they are directly involved in the crushing process. In order to enhance the durability of these two parts, the crusher is made of high manganese steel or composite alloy, both of which have extremely high hardness and wear resistance. At the same time, the anti-wear and anti-impact properties of these parts have been further enhanced through a special heat treatment process. This means that these parts are able to maintain good shape and dimensional accuracy over a long period of time, thus ensuring that the crushing effect of the crusher remains consistent. According to statistics, the service life of the movable and static jaw plates made of high manganese steel or composite alloy can be increased by more than 30% compared with ordinary materials. This means that users can reduce the frequency of replacement parts, thus reducing maintenance costs and production downtime.

Easy maintenance

The crusher has a modular design, which makes the connection between the various components simpler and more standardised. When a component needs to be serviced or replaced, the user only needs to follow the established disassembly and assembly procedures, without the need for complex commissioning and calibration work. At the same time, key components such as bearings and jaws are designed to be easily replaced without the use of special tools. This makes maintenance quick and easy and reduces downtime.

Intelligent control

The crusher can also be equipped with an optional automation system (e.g. ASRi) that monitors the crusher's load, discharge size and operating parameters in real time. By analysing and processing this information, the automation system intelligently regulates the crusher's operating conditions to ensure that it is always in optimum working order. This not only improves the crushing efficiency and processing capacity of the crusher, but also reduces energy consumption and the probability of failure. According to test data, after adopting the automation system, the energy consumption of the crusher has been reduced by more than 15%, while the failure rate has been reduced by more than 20%. This brings higher economic benefits and a better experience for users.

Low Operating Costs

The crusher adopts a combination of low energy consumption motor and high efficiency drive system, which significantly reduces the power consumption of the crusher during operation. At the same time, the use of long-life components also reduces the frequency and cost of maintenance. These factors combine to optimise the overall operating costs of the crusher.

CJ412 Jaw Crusher, Heavy Industry Preferences Working Principle

The CJ412 Jaw Crusher is a highly efficient and durable crushing plant, which operates on the principle of ‘curvilinear compression’. Under the guidance of this principle, the materials are firstly fed into the crushing chamber through the feeding device in a smooth and orderly manner. Inside the crushing chamber, the static jaw plate is firmly fixed to the front wall of the machine body, forming a solid crushing datum, which provides stable support for material crushing. When the motor is started, it strongly drives the eccentric shaft to rotate through the pulley. This rotating action drives the movable jaw to carry out periodic reciprocating motion. When the movable jaw is close to the static jaw plate, the material is tightly squeezed between the two, bearing great pressure, so as to achieve effective crushing. When the movable jaw is far away from the static jaw plate, the crushed material moves downward naturally under the action of gravity until it is finally discharged from the discharge opening.
The width of the discharge opening of CJ412 Jaw Crusher can be adjusted according to the actual demand. This adjustment is achieved by hydraulic or mechanical wedge system, which is very convenient and accurate. By adjusting the width of the discharge opening, users can flexibly control the particle size of the finished material to meet the needs of different processes. Normally, the adjustable range of discharge opening of CJ412 Jaw Crusher is between 70-200mm, which provides users with a wide range of choices. During the crushing process, if some materials are still not up to the required size, they will stay in the crushing chamber and continue to receive the squeezing action between the movable jaw and the static jaw plate. This process will continue until all materials meet the discharge conditions. This design ensures that the CJ412 Jaw Crusher is able to produce finished materials of uniform size and consistent quality.
