Mining broken sand is the important aggregate that is indispensible to configure concrete aggregate and accounts for more than sixty percent of the concrete proportion. With the fast development of the infrastructure construction, building sand becomes more and more important for the quality of the engineering projects.

Vertical mill set, drying, grinding, fine powder separating and conveying into a whole, is the first choice and processing of slag cement. At the same time,  lum ultrafine vertical roller mill  grinding cement accounted for the ratio in the world has changed: in 2004~2005, the vertical mill grinding cement accounted for the ratio in the world for 26% years, 2008~2009 for 61%,2011~2012 years to reach 83%.

Currently, all provinces and cities in China continue to explore new ideas and vigorously develop infrastructure projects so that actively enhance the competitiveness of regional economic development. Any construction site basically cannot be separated from the sand and gravel aggregate supply.

Through a modern managerial approach, we can accumulate management and production experience. This is how Zenith has become a technically-advanced mining crusher-machine manufacturer in China. Currently, we have over 1000 staff members, 138 intermediate and senior engineers, and 200-plus technicians. Our company is located in shanghai, where we are in close proximity to an international port, highways, and airports, for convenient transportation. This enables us to reduce our manufacturing cost; and also save our customers on international shipping.

With steel prices caused Sand price looks very rapidly, machinery industry had a very competitive price makes the profit margins of manufacturers of Sand and greatly reduced. In particular, recent steel price ups and downs, sand making machine  is difficult to stabilize prices, want customers to seize the time to invest their savings, sand making equipment prices and steel prices are closely related.

In the sales process of sand making machine , sales staff often encounter situation that some customers come to the factory just for seeing the river gravel sand maker , although the river gravel sand maker is the must-see flagship product. When asked about the reason, many people gave the same answer: river gravel sand making machine has the greatest reputation, and it’s practical, we just want to buy the river gravel sand making machine. In this case, manufacturers must point out the misunderstanding of customers.

With the national freeway plan implementation, artificial sand and aggregate in the society to further increase the dosage, stone production line equipment is also widely used in society, all kinds of mobile SBM production of the crushing station is in recent years the city construction waste can be used as the best choice for processing equipment problems.

Over the past few years, with the rapid development of domestic infrastructure construction, cities and new rural construction, the domestic sand and gravel aggregate crushing and mechanical  sand making machine   has also been developing fast, and the traditional sand and gravel aggregate was mainly manufactured by natural sand.

Raymond  Mill is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials, such as barite, calcite, feldspar,talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 mesh to 325 mesh according to requirements.
