Nowadays, most of the sand on the market is machine-made sand, which is obtained by crushing stones. Its mining is easy and unrestricted, the cost is low, the quality of the finished product is good, the selling price is high, and the sales volume is good. Therefore, many people invest in stone powder sand projects. If you want to grind stones into sand, you must choose a suitable sand making machine. Today, the equipment we recommend to our customers is a roller crusher. Let’s introduce it in detail.
What machine is used to turn stones into sand?
Roller crushers are often used as important stone processing equipment in various small and medium-sized gravel plants. They can crush various stones with a compressive strength of less than 160 MPa. They are used in industries such as coal crushing, construction material production, refractory material processing, metal smelting, and cement preparation.
The double roll crusher mainly relies on the squeezing force of the counter-rotating grinding rollers to successfully crush the stones. The wedge block set between the two rollers can adjust the output particle size of the counter-roller. The operator only needs to adjust the bolts above the wedge block by pulling up or pulling down to achieve success, greatly facilitating the operation steps of on-site personnel, and also improving the quality of the product.
What is the principle of making sand from stones?
The double roll crusher is composed of two squeezing rollers that rotate in opposite directions, one is a fixed roller, and the other is a movable roller. The material is fed from above the two rollers, and the squeeze roller is continuously carried between the rollers, subjected to a high pressure of 50-200MPa after the action, the material is discharged from the machine with the ideal particle size. The material starts to be bitten by the roller surface, and the force of the roller gradually increases. The discharged material, except for a certain proportion of powdered material, is generated inside the rest of the granular material. A large number of cracks can greatly reduce the energy consumption of grinding during the further crushing process.
How much is a machine that turns stones into sand?
Since the price of a double roll crusher in the market is not fixed, it can be influenced by various factors such as equipment quality, manufacturer, technical specifications, and market supply. As a result, it can be challenging to determine the exact cost of a machine that can crush stones into sand. Therefore, it is recommended that users consult with specific roller crusher manufacturers for detailed pricing information.
