Which effect of limestone sand making machine is better to use?

Limestone generally refers to limestone, calcite as the main component of the carbonate rock, the structure is more complex, there are clastic structure and grain structure, but in the current era of machine-made sand vigorously, can limestone sand make sand? Can it be used as building material? Which effect of limestone sand making machine is better to use? Let’s take a look at it here.

One. Which effect of limestone sand making machine is better?

Impact sand making machine.

Limestone hardness is generally not large, Mohs hardness is about level 3, the property is brittle, belongs to the hardness of rock, and is widely distributed, uniform lithology, easy to mining and processing, so limestone can make sand, at the same time according to the relevant characteristics, the use of impact sand machine effect is better, through the combination of stone and stone iron two ways of working, Output per hour 60-650 tons, feed particle size ≤50mm, complete equipment models.

Good quality of finished products:

The fineness modulus of limestone products can be adjusted, coarse sand (above 0.5mm), medium sand (0.5-0.35mm), fine sand (0.35-0.25mm), etc., which is mainly adjusted according to the actual process requirements of customers, with good grain type, stable quality, clean sand, no mud and other harmful impurities, and stable chemical properties. And in the use of cement and other structural bonding, adhesion is good, more compressive, longer service life.

Environmental protection standards:

This limestone sand making machine has high environmental protection, sealed dust collection device is set up at the inlet and outlet, which can effectively reduce dust pollution. The crushing chamber adopts the self-circulation mode, the material can be fully collided in the crushing chamber, and the dust is in the sealed interior. In the production process, it is also equipped with a covering device and spray treatment to realize green and environmental protection production.

Advantages of equipment:

The feed port is equipped with a screening device so that the limestone is screened before entering the impact sand machine to remove impurities, so that the sand produced is clean and free of impurities.

The use of combined throwing head, only need to replace the wear part, can reduce the use cost.

The protection plate can be turned up and down to prolong the service life. The hydraulic cover opening device is convenient for maintenance.

The lubrication mode can be selected. The modular design of thin oil type and grease type in the bearing chamber can realize the whole interchange.

Two, can limestone be used as building material?

It’s OK.

Limestone itself is a very wide range of building materials, decomposed into calcium oxide and carbon dioxide at high temperature, used in the production of lime, cement, at the same time has thermal conductivity, firmness, water absorption, air permeability, sound insulation, polishing, good cementation properties and machinability and other properties, both can be directly used raw ore, can also be deep processing applications, such as after sand making, It can also make glass, refine steel, make rubber, cosmetics, toothpaste and other fields.

1. Make glass

It can be used to make glass. After melting at high temperature, glass can be extracted. It is the main material for making glass.

2. Refining steel

In industry, limestone is also used to refine steel. In this case, quicklime is usually used, which filters out harmful substances such as sulfur and phosphorus.

3. Make rubber, cosmetics and toothpaste

When fired, it turns into a pure powdery form of calcium carbonate, which is used to make toothpaste, cosmetics and some rubber products.
