Demand for sand and gravel with the real estate development, road and railway construction, water conservancy and power construction and other projects started, is rising, which also drives the progress of sand making machinery, combined with the development of high and new technology in recent years, now the new type of sand making equipment to produce sand not only can completely meet the standards of construction sand, but also in the degree of automation has been improved a lot, it can be said that the current cobblestone sand machine is a combination of high yield and Intelligent as one.

First, how to choose the new pebble sand making machine?

Cobblestone as the main raw material for sand production has two main reasons: one is rich in resources, low mining difficulty, and the second is the high hardness, the finished product made of better quality, known as the ideal type of green building materials. But also because of its high hardness, in the selection of sand making equipment needs special attention, to avoid the phenomenon of poor impact resistance of the equipment and lead to the high cost of the late, that in the new sand making equipment we said, which one is better?

Pebbles and finished products

Pebbles and made of sand Finished product size can be adjusted

1, two pebble sand making machine performance characteristics

HVI impact sand making machine: the design of the deep cavity impeller, effectively improve the material throughput by 30%; in the process design is relatively more advanced, both bearing chamber thin oil type and grease type two kinds, and is modular design, can achieve the overall interchangeability, very convenient; there are also perimeter guard can be up and down the head, throwing head for the combination, etc., to effectively save more than 10,000 yuan of the use of the cost of the late.

VSI sand making machine: its working principle can be both "stone to stone" and "stone to iron", for different materials, different working principles can be applied; in order to facilitate the daily maintenance and conservation work, the application of hydraulic cover device, reduce the downtime, reduce the labour of workers. In order to facilitate the daily maintenance and care work, it applies the hydraulic opening device to reduce the downtime and reduce the labour intensity of the workers, and the wear parts are all made of high wear-resistant materials, which have good performance of impact resistance and wear resistance.

2, two kinds of sand making machine crushing capacity

The working principle of HVI sand making machine and VSI sand making machine is to use impact energy and kinetic energy to carry out crushing operation, the material in the crushing chamber is not only subject to the kinetic energy exerted by the equipment, but also in the material and the impact force between the material, so the two production of finished products with rounded and smooth angular shape, the overall grading is also more reasonable.

HVI impact sand making machine and VSI sand making machine in the treatment of pebbles, both can do to ensure the quality and output, but the above skills advantage basically allows you to decide which sand making machine to choose, because the actual situation of each user will be different, the specific is still based on the actual needs of the user.
