Sand and gravel industry is an important link in the national economy construction, which can not be replaced. Construction, infrastructure, traffic construction are inseparable from the gravel,30 years of reform and opening up, China's construction industry gravel as important foundation material, as national infrastructure construction made important contribution to promoting national economy, fast development of. At present, sand and gravel industry already formed 300000000000 yuan market scale, directly or indirectly related to the development of the industry, transportation industry only pull produced nearly 200000000000yuan economic benefits. Sand and gravel industry development, promote the rapid growth of GDP directly, for the community to create a large number of employment opportunities, to national economy development made outstanding contribution.

Hongxing machine limited company is committed to the sand preparation equipment R & D and production, developed a third generation of sand making machine, suitable for sand stone raw material crushing. The development of a new type of impact crusher is widely used in sand and gravel industries such as fine works, particle shape of a cube, low content of needle-like particles, the mechanisms for building sand, stone and a variety of metallurgical slag crusher is much more widespread use, and other types of crusher compared to yield high efficiency. Hongxing R & D third create pressure-blasting machine has stable and reliable work, convenient repair, sand production rate is high. Sand and gravel industry to strive for further improvement, we must upgrade mining way, accelerate technical innovation, change management, improve utilization efficiency. Hongxing machine limited company hope that through the development of a new type of impact crusher improvement of sand and gravel industry exploitation way, improve the utilization rate of gravel mining gravel, to Chinese industry bigger and stronger to make a contribution.

On the basis of keeping the function of sand making machine, it also enjoys some special and new Highlights as below: rock crushers:http://www.hx-crushers.com/p3.html

1. The patented design of “high-efficiency material flow swinging impeller (HEMFSI)” highly increases the processing capacity; the theory of stone hitting ensures low energy consumption and high crushing efficiency.

2. The process of crushing is intense with high crushing efficiency. Presently, this type of sand maker is the most popular in the market. The patented design of “Material flow dividing” is more scientific to the gravitation principle.(manual adjustment to control the material flow feed-in, it also can feel the adjusting extend outside),which is also help to increase the whole capacity.rotary kiln:http://www.hx-crushers.com/p66.html

3. The improvement of vortex reflecting cavity highly increased the crushing frequency, so save much cost of the wearing parts of vortex cavity for user. The consumption of quick-wear parts is low. The sand maker is designed with the best crushing angle within the cavity and causes little friction with wear-resistant parts.

4. The sand maker requires 30% less operating cost than traditional equipment. It helps clients reduce equipment use-cost. Butt ends designed by changing from “one section” to “three sections”, users only have to replace the damaged section part, so it is also a thoughtful design for users to save cost of wearing parts.

5. The cubic-shaped product is rationally graded with adjustable fineness modulus. The sand maker is lubricated with grease specially used by Mobil.

6. Non-crushing materials can easily pass the crushing cavity. The influence of feedstock humidity is reduced to a favorable extent. The moisture content can be up to 5%. The sand maker is so environmentally-friendly that it causes little noise and pollution when operating. The operating sound is below 75 dB and no dust is created.
