Every holiday is the peak traffic flow, especially during each year’s Spring Festival gave special test of railway and highway transportation, and two reasons caused this situation: one is the large floating population in China, the second is our means of transport is far from meeting the needs of people to travel.

Repair railways and roads has become a matter of urgency, whether it be building roads, railways, viaducts, across River Bridge, tunnel or rail transport, they require a large amount of sand and gravel aggregate, and to produce a gravel crusher of aggregates requires high performance, so as to produce high quality sand and gravel aggregates. The sand making machine is the essential machinery and equipment in the course of building road, railways, viaducts, tunnels and subway construction. The sand making machine are mainly used in the manufacturing of different kinds of sand and stone. The overall performance boost of sand stone making machine is to reach 30% percent, which has brought the most powerful guarantee for China’s high speed road construction, railway construction of the extension of the viaduct, tunnel and subway development.

In order to use strategy of sustainable development, a few enterprises begin to choose green sand making machine with high science and technology and production ability, and these equipments only need to change parts to immediately go on working when problem arise, which needn’t change the whole machine, so the emergence of new chemical equipment makes the market share of crusher accessory higher.
