Now the sales network has become the industry eagerly between the development of an important means, sand making equipment by the network sales can greatly enhance the visibility of the enterprise, this kind of manipulation and traditional marketing means different to, network marketing can be more efficient, more efficient, but the Internet due to the lack of supervision mechanism, in the sand equipment marketing process, many enterprises lack of credibility hindered the development of sand making machine manufacturers. Some, small sand making machine manufacturers because of the lack of visibility, for the pursuit of sales results and to take improper means to harm the interests of consumers, but also at the expense of sand making machinery industry’s image.

From the early 1960s, traditional dry sand processing mathod had turned up in China.But the traditional technology have several fatal disadvantage,such as the poorly equipped,small production, dust hazard,big noise, environmental pollution and so on.They matched the high energy consumption and high costs but didn’t solve the problem of environmental pollution. Hxjq Heavy Industry improved the first vetical impact crusher (PCL series sand making machine)and finished the world's advanced level high-performance sand making equipment – VSI type sand making machine, which is comprised of rotor, spindle, crushing chamber, motor, transmission, automatic control systems, lubrication systems, and steel and other components. And the main wear parts,example the rotor matrix, throwing hoppers, sub-feed pan, anvil , adopts wear and impact resistance alloy materials.All of them are provided with the long life and easy replacement. The crush form is divided into 'rock on rock' and 'rock on iron'.According to material compressive strength, abradability,there are four working forms: central with cascade feeding 'rock on rock' and rock on iron'; central feeding 'rock on rock'and 'rock on iron'. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery,

Features of the economy third generation

(1) Simple structure, low cost;

(2) High efficiency and energy saving, crushing efficiency;

(3) With finely, coarse grinding function;

(4) With a strong ability of the material moisture influence small, moisture content 8% ;

(5) It can be break hard, very hard in material (such as corundum, sintering aluminium vanadium and soil, etc.);

(6) Products are in the cube, iron pollution small;

(7) The impeller and crushing cavity vortex move the materials in the line from greatly reduced wear parts costs and maintenance work;

(8) The operation, maintenance, installation are convenient;

(9) The noise is less than 75 decibels (dB magnitude);

(10) Light weight, installation is diversiform, can be mobile installed, etc.

The production of the new sand maker has replaced the traditional manufacturing technology. It becomes indispensable aggregate equipment in sand aggregate industries. With the development of domestic infrastructure construction, there’s a great demands for technology upgrades, quality improvement and stable performance to meet extensive demands for sand aggregate.
