Analysis of the differences in jaw crusher products

In the market, there are many types of jaw crusher products, and there are significant differences between different products in many key aspects. These differences directly affect the performance, applicability and cost of the equipment.

Rack structure: the contest between welded and assembled

There are two main types of jaw-breaking racks, welded and assembled.The welded rack structure is relatively simple, and the cost investment in the manufacturing process is low.However, due to the characteristics of the welding process, welding deformation is prone to occur, which may have a certain impact on the overall stability of the equipment.In contrast, the assembled rack, with its high-strength characteristics, effectively avoids the stress concentration problem caused by welding, making the machine more durable, especially suitable for large-scale products.But it cannot be ignored that its high manufacturing cost has also become a feature of it.

Broken cavity type: Traditional and new innovation

The design of the crushing cavity type plays a key role in the jaw crusher.The traditional crushing chamber presents a "right triangle”, while the new crushing chamber is designed as a ”symmetrical isosceles triangle".The new design makes the particle size of the feed larger, which greatly improves the feeding capacity and output.From the perspective of angle, the angle between the new type of jaw fracture is between 18°-21°, while the angle between the traditional jaw fracture is between 21°-24°.A smaller angle means greater crushing force and stronger processing capacity, which also reflects the performance advantages of the new crushing cavity type.

Discharge port adjustment method: the difference between gasket type and wedge type

The adjustment methods of the discharge port are mainly gasket type and wedge type.Gasket adjustment requires disassembly and assembly of fastening bolts during operation, which is more cumbersome and inconvenient for maintenance work.Wedge-type adjustment has greater flexibility, and can be adjusted mechanically or hydraulically according to actual needs, making the operation simpler, time-saving, and safer.

Motor installation method: integrated and independent considerations

There are two types of motor installation methods. One is the integrated installation of the motor on the crusher rack. This method saves space and produces less vibration on the foundation, but the reliability of the motor quality is higher.The other is the independent installation of the motor installed on the foundation, which has greater vibration on the foundation and therefore higher requirements on the foundation.

Bearing and housing design: Key design of core components

As the core component of jaw breaking, bearings have strict requirements in design and manufacturing.The new type of jaw breaker adopts double-row tapered roller spherical bearings, which can better adapt to the complex working environment.The design of the bearing seat is also divided into integral and semi-open, and different designs are suitable for different work scenarios.

Lubrication system: the transformation of manual and centralized hydraulics

The lubrication system is essential for the normal operation of the jaw crusher.Ordinary broken jaw adopts manual lubrication, while the new type of broken jaw adopts centralized hydraulic lubrication. This method makes bearing lubrication more convenient, can effectively reduce the failure rate, and provides great convenience for later maintenance work.

Through the understanding of the differences in these aspects, users can more accurately choose suitable jaw crusher products according to their actual needs and budget.
