What equipment is used for crushing hard rock to make sand?
In recent years, the development prospects of the machine-made sand market have been relatively optimistic. With the help of the “One Belt, One Road” and “13th Five-Year” policies, my country’s construction and transportation have begun to increase investment, and more and more aggregates are needed. Many, using hard rock as raw material for machine-made sand has become a good choice. So the question is what equipment is used for hard rock crushing and sand making? This article will introduce to you.
1. A brief introduction to the concept of hard rock
There are countless types of rocks in nature, so how to distinguish hard rocks? Generally, it can be judged by the saturated uniaxial compressive strength. Rocks greater than 60MPa are called hard rocks, and those between 30-60 are harder rocks.
For example: granite, diorite, basalt, limestone, marble, sedimentary rock, quartzite, slate, dolomite, limestone, gneiss, etc. are all called hard rock. After crushing and sand making, it can be It is well applied to roads, bridges, municipal construction, airport runways, railways and other fields.
Hard rock raw materials
The process of hard rock crushing and sand making is generally divided into two stages of crushing + one stage of sand making. Due to the hard rock texture, ordinary crushers are slightly difficult to handle. In actual crushing and sand making operations, higher costs are required.
1. Jaw crusher coarse crushing: generally used for head crushing and coarse crushing. It adopts the working principle of extrusion crushing. The crushing cavity is deep and there is no dead zone. The integrated structure of the motor base and the host makes the installation easier and saves occupation. space.

2. Cone Crusher Medium Crushing: Mainly to reduce abrasion and improve efficiency. It is based on the principle of laminated crushing. It adopts the concept of more crushing and less grinding. It has stable operation, high crushing efficiency, energy saving and consumption reduction, convenient clearance and crushing capacity. Strong, safe and environmentally friendly, hard rock secondary crushing to meet different needs.

3. Hard rock crushing and sand making process
The hard rock crushing and sand making process is relatively simple: first, the large pieces of hard rock raw materials are fed by the vibrating feeder into the PE jaw crusher through the silo for preliminary crushing; then the belt conveyor is evenly fed to the high efficiency Further fine crushing processing in the hydraulic cone crusher; and reasonable screening treatment through the circular vibrating screen to obtain the crushed material whose particles meet the sand making conditions, which will enter the VSI sand making machine for sand making and shaping; if you want to get a cleaner, High-quality machine-made sand needs to be sent to the sand washing machine for cleaning and impurity removal.

4. What is the price of hard rock crushing and sand making equipment?
How much does it cost to configure a set of hard rock crushing and sand making equipment? According to market understanding, it ranges from hundreds of thousands to one million yuan, which is mainly related to output, configuration plan, and equipment model selection.
