Henan Zhengyi is a large-scale enterprise specializing in the production of crushing equipment. Its products include roll crusher, jaw crusher, impact crusher, cone crusher, stick crusher, hammer-hammer crusher, and sand-making machine. Sand washing machine, ball mill, energy-saving ball mill.

The roll crusher has a low investment cost, and its broken sand product quality is not high. It is suitable for use in low-grade sandstone aggregates for buildings. The roll crusher has become an economical sand making equipment.

At present, in Guangdong , Hunan, and Shandong, there are many gravel yard sand stone production lines used, and bring good economic benefits to users. However, many roll crushers on the market are relatively traditional. Not only are they not stable enough in performance, they also consume too much energy, and they have a high rate of sand aggregates produced.

It is critical to reduce the energy consumption of roll crushers and achieve energy conservation and emission reduction. Many domestic mining machinery companies are trying to improve the research and development of roll crusher technology and promote the upgrading of roll crusher products. Henan Zhengyi has a great deal of energy in the roll crusher, and its production of roll crusher equipment is not only volume. Small, large crushing ratio, low noise, and energy consumption is reduced by 30%. The gravel aggregate produced by it has uniform grain size, which solves the problem of low over-comparation rate.

Henan Zhengyi Sandstone Business Division explained to us that the main reason why the roll crusher is widely used is that the investment cost is low, but the quality of sand aggregate produced by him is not good enough, so it is not generally used in large-scale buildings. High-grade buildings such as high-speed railway buildings and hydroelectric dams. If it is to provide sand aggregate for these areas, it must adjust the equipment configuration and production process of the sand production line, use Henan Zhengyi hard rock counterattack, efficient sand making king (sixth generation sand making machine), super Fine cone crushers and other equipment, they show good performance in the crushing operation, not only the large production capacity, high crushing efficiency, greatly reducing the operating costs, but also important to the use of counterattack as an orthopedic equipment, produced sand and bone Good cooking, high grading, and counterattack are the best equipment for plastic surgery.

Henan Zhengyi Sand Making Production Line provides a full set of equipment, specially designed for in-person installation and guidance, freeing you from worries. The sand production line of our company mainly consists of vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor, centralized electric control and other equipment; in addition, it can be equipped with cone crusher, dust removal equipment and so on.
