Selecting the right sand and gravel production equipment according to the demand for sand and gravel aggregates for concrete

Concrete plays a vital role in road traffic construction and civil engineering. Concrete is mainly divided into cement concrete, asphalt concrete, mortar three categories, different kinds of sand and gravel material required particle size varies, used for different construction projects, with the improvement of the finished product requirements of sand and gravel aggregate, coupled with people's awareness of the change, high-quality sand and gravel aggregate is increasingly popular, along with also led to the production equipment hot sales.

Concrete is one of the most important contemporary civil engineering materials, concrete ingredients need a large number of sand and gravel aggregates, playing a skeletal role, transferring stress, even without cement paste, aggregates can also support the load, while inhibiting shrinkage, to prevent cracking. Concrete used in sand and gravel technical indicators should be consistent with the stone particle size should not be greater than 40 mm, the soil contained in the stone shall not be lumpy or wrapped around the surface, water absorption rate of not more than 1.5% of the provisions. Sand and gravel aggregate for the aggregate components of concrete. Artificial sand and gravel should be given priority over natural sand and gravel selection. Artificial sand is much better than natural sand in concrete setting time and firmness. So to go through the crusher, sand making machine sand and gravel shaping action, so that the sand and gravel to present different shapes of polyhedra, increase the contact with cement cementitious materials, reduce the gravel and gravel between the void, so as to fully ensure the firmness.

The development of concrete industry provides a huge space for different sand and gravel crushing and screening equipment. The sand and gravel aggregate production system includes jaw crusher, impact crusher, cone crusher, sand making machine, belt conveyor, vibrating screen, vibrating feeder, etc., which form a complete sand and gravel aggregate production line.

These sand and gravel equipment through the engineering designers carefully formulated and matched to create a variety of stone specifications and different output of concrete aggregate production line, specific details of the formulation can consult the sand and gravel equipment manufacturers, you are welcome to click online customer service for more information.
