Can granite be made into machine-made sand? Can the finished granite sand production meet the requirements of construction materials? After being processed by a professional granite sand making machine, the aggregate quality of machine-made sand made from granite is also very high, which can meet the needs of construction sand? Granite has high quartz content, low sulfide content, hard and compact texture, high strength, corrosion resistance, good wear resistance and stability. This hard rock has a compressive strength of more than 30MPa and is a good raw material for sand making. It is very common in sand factories. The machine-made sand can produce finished stone products of various specifications (0-5-10-15-20-30mm) to meet the material needs of construction, building materials, cement, roads and other fields.
Granite sand making process because of the hard texture of granite, granite sand making generally requires three stages: jaw crusher + hydraulic cone crusher + sand making machine
First, the granite enters the jaw crusher for coarse crushing. After coarse crushing, the aggregates that meet the requirements are transported to the cone crusher for crushing by the belt conveyor, and the aggregates that do not meet the requirements are transported to the jaw crusher by the return belt to be crushed again. After the aggregate is crushed by the cone crushing station, the aggregate that meets the requirements is transported to the sand making machine-made sand by the belt conveyor, and the aggregate that does not meet the requirements is transported from the return belt to the cone crusher for re-crushing. After crushing, the materials in the sand making station can be directly divided into finished sand and gravel products of different particle sizes through the screening station.
The crushing equipment commonly used in the whole crushing process is as follows:
Jaw crusher: As a jaw crushing station for coarse crushing, the compressive strength is up to 320MPa, which can be used for primary crushing of high-hardness materials in various industries.
Cone crusher: adopts laminated crushing, with material layer protection device. The feed size is 0-360mm, which has the characteristics of high efficiency, large output, and high efficiency, low wear cost of wearing parts, extremely high reliability, high-quality finished material particle shape, compact transportation size, and convenient transportation.
Sand making machine: This is the key equipment in the entire granite sand making process. Since the finished product processed by the cone crusher contains more needles and flakes, it is necessary to use an impact sand making machine to perform an optimized shaping treatment. The sand making machine adopts two crushing mechanisms of "stone beat stone and stone beat iron", and the discharge size is uniform and cubic, and the finished product is of high quality.
Special attention should be paid to the purchase of sand making equipment for the sand and gravel production line. Only by selecting the appropriate sand making equipment can the output of the production line and the particle size gradation of the finished product be guaranteed in the later stage. The following introduces the aspects that need to be paid attention to when choosing a river pebble sand making machine:
1. Try to shop around and inspect the equipment at the production base of the sand making machine manufacturer. Only by comparing a few more can you choose the better equipment;
2. Try to choose a strong and large-scale sand making machine manufacturer, and choose a manufacturer with higher cost performance among manufacturers of the same type and scale;
3. If investment funds are limited, you can consider buying in areas where there are many sand making machine manufacturers, such as Henan, which is located in the Central Plains. The local equipment where manufacturers gather is more competitive, and the price will be relatively more favorable;
4. Choose direct-selling manufacturers as much as possible. Direct-selling manufacturers do not have a middleman to earn the difference when selling, and the equipment prices are all ex-factory prices, so the quotation is relatively low;
5. When selecting sand making equipment, visit the manufacturer's sand making production site as much as possible to understand the use of sand making equipment.
