The price of a jaw crusher jaw depends on several main factors. The most important of these is the material and quality of the steel, as the higher the strength and durability, the higher the price. The dimensions and size of the jaw jaw also have a direct impact; larger jaws cost more. In addition, the manufacturer’s brand, transportation costs, and fluctuations in the price of raw materials affect the final price.

Our professional engineers, with their excellent technical knowledge and practical experience in jaw crusher design and manufacturing, produce each product according to strict standards and guarantee its optimal performance and long service life.
Unfortunately, many sellers offer low-quality or even counterfeit jaw crusher jaws, which cause rapid machine failure, frequent stops and increased maintenance costs. However, Novin Sand Maker jaws are completely different; these products are made of durable steel and meet high industrial standards, are available in various sizes and strengths, and have a long service life.
The jaw comb is one of the main components of the jaw crusher, which is used in the primary crushing process of minerals. This part is divided into two types: fixed and movable. The fixed jaw comb is in a fixed position, and the movable jaw comb compresses and crushes the material between the two jaws with its reciprocating motion.
Jaw shoulders are usually made of manganese steel or manganese-molybdenum steel, which have high wear resistance. In some cases, Ni-hard cast iron is also used to increase durability. The right jaw shoulder material increases the useful life of the machine and reduces maintenance costs.
The fixed jaw shoulder is in a fixed position and acts as a support, while the movable jaw shoulder compresses and crushes the material between the two jaws with its reciprocating motion. This interaction between the two jaws causes the material to be crushed.
The jaw jaw dimensions should be selected according to the jaw crusher model and the type of incoming minerals. For example, in mines with hard and resistant rocks, jaw jaws with smaller pitches and closer protrusions are used to achieve more effective crushing.
To increase the life of the jaw jaw, the following points should be considered:
By following these points, sudden failures can be prevented and the device’s efficiency can be increased.
