Jaw crusher design and manufacturing process: Over the past 20 years, against the jaw crusher of the four-link movement method of mechanical design theory has great progress. For example: a two-way Nie crushing chamber angle, short bracket put on a large angle to reduce the transmission angle and eccentricity and so on, the products offered by foreign companies tend to have validated the use of these advanced design theory to improve product performance and reliability. China’s domestic manufacturers a variety of reasons very little use of advanced design theory, its main products were almost exclusively the 20th century, before the 70’s established products, using wear-resistant materials, (such as high-manganese steel) and the important component parts (such as the self-aligning roller bearing) and other domestic-based pieces, life below the international advanced level of similar products. In addition, OEM processing and assembly process and less on the years there is a change, such as the bearing hole, bearing the processing rack assembly process and the processing and assembly and so on.

The industrial jaw crusher is based on a revolutionary modular, non-welded frame construction, offering owners the highest possible fatigue strength, excellent reliability and numerous mounting possibilities. Thanks to the accurately balanced structure, the industrial jaw crusher is one of the most easiest and economical crushing machine to install. Combined with special high-quality cast steel components and durable wear parts, means exceptionally high crusher availability, cost-efficient crushing and low cost per ton. In all, industrial jaw crusher has simple structure, which bring about easy maintenance; stable performance; even final particles and high crushing ratio.

Jaw Crusher Technical Features:
1. Professor Dai Shaosheng using the “fixed capacity” linear ─ ─ amendment Gaussian highly crusher chamber, so that materials in the crushing chamber by a certain degree of “pyramid smash,” and the crushing effects of pure pressure of five times shear stress, the material in the crushing chamber by repeatedly laminating smashing effect, so leading to significantly increase the machine crushing effect, broken efficient and nesting average particle size of up to 5-10mm.

2. Nie angle from zero becomes negative, so that materials will not only not blocked, but with the linear moving jaw plate longer constitute a “balance zone”, its effective length 30-60mm, so that nesting period of time by the parallel squeeze (grinding) pressure effect, further thinning of materials, and enhanced nesting, material to the discharge area at the bottom, crushing chamber opening increased and accelerated the marker, fundamentally eliminating nesting block defects and improve output.

3. To ensure the materials broken cavity and increase the number of broken extrusion ratio, increasing the height of the technology appropriate height of the crushing chamber to form the so-called “profound style” crushing cavity; In order to increase production, export a new eccentric shaft speed formula, that is patented eccentric shaft speed can reach 330-350rpm. This increases the number of fixed jaw swinging, both to strengthen the role of fragmentation, but also increase the machine output.

4. Fu swing jaw crusher jaw plate wear and tear of the law is generally fixed jaw tooth plate in nesting areas and rapid wear of the upper part of the region, for which the technology will be fixed jaw plate 作成 “straight ─ ─ amendment Gaussian curve-type” . This innovative design has been excellent results. Practice has proved that, indeed improved crusher jaw plate wear, and using a new alloy materials to increasing life expectancy by 2-3 times.
