The requirements for sand and gravel on expressway are very strict, because the quality of sand and gravel on expressway is related to the service life of expressway. According to GB/T14684-2001, machine-made sand is defined as rock particles with particle size less than 4.75mm (excluding soft rock and weathered rock particles) produced by mechanical crushing and screening. Generally, the surface density of sand is more than 2.5 and the water absorption is less than 3%.
Highway sand and gravel mainly refer to machine-made sand, and is very conducive to highway construction. SMMVIK Machinery takes customer service as the overall value goal, and our manufacturing enterprise is also a service-oriented enterprise. If we want to do better in the field of mechanical services, we must have a solid technical foundation, because we are facing more and more diversified customer needs and personalized services, we may face more complex practical production problems.
In fact, many problems are not difficult to solve, but it is difficult to find a better solution. A good solution can reduce a large amount of investment for enterprises. This is what SMMVIK Machinery is trying to do to provide you with better highway sand and gravel production lines. The tire type mobile crushing station and crawler type mobile crushing station produced by SMMVIK Machinery are designed to adapt to the mobility of highway construction.
Because the sand machine of sand and gravel production equipment for expressway is often engaged in impact grinding operation, it is particularly prone to wear and failure. In order to solve this problem, SMMVIK Machinery R&D team adopts a combination structure, which is very convenient for maintenance and makes maintenance easier.
