This is first determined by the properties and hardness of granite. Granite is a high-hardness rock that is difficult to crush and has a large wear on the crusher. Therefore, a reasonable crushing scheme is critical for later production.
Generally, the primary crushing needs jaw crusher, the granite can be crushed to 10-30cm.
Next, for secondary crushing, hard rock such as granite, cone crusher is more suitable. Currently, there are spring cone crusher and hydraulic cone crusher. According to different cavity types, we can choose short head type and standard type, single cylinder hydraulic cone crusher and multi cylinder hydraulic cone crusher. Although the initial investment is higher, the operating cost will be much lower later, avoiding the normal operation of the production due to frequent replacement of parts and maintenance.
The cone crusher can directly crush stone into 5-10/10-15/15-20/20-31.5 and other different specifications of stone materials.
If you want to produce mechanism sand at the same time, you can add sand making machine after the cone crusher to produce 0-5mm mechanism sand.
The middle is supplemented with vibrating feeder, vibrating screen, belt conveyors, sand washing machine and other ancillary equipment.
This is a relatively complete granite crushing production line, which can increase or decrease equipment in actual production.
The raw material of granite is large in volume. We need to crush the granite into the stones and sand in the building aggregate. Then, it needs to go through coarse crushing, medium crushing and fine crushing. Only after these three crushing systems, we can get the building aggregates that meet the requirements.
1. Coarse crushing stage of granite crushing: conventionally, coarse crushing generally uses equipment that is crushed by laminating technology. Normally, jaw crushers are used in sand and gravel yards. The jaw crusher has a simple structure and stable operation. The crushing capacity is large, and the inlet specifications are various. The inlet that can swallow the crushed materials are also larger, so it is suitable for the coarse crushing of various materials.
2. Medium crushing stage of granite crushing: because of the high wear resistance and hardness of granite, the wear-resistant parts are very severely worn during the crushing process. Therefore, it is necessary to crush the granite to a size close to the required finished product size first, and then perform the final shaping and crushing. Among all the crushers, the crushing equipment using the lamination principle has the lowest loss of vulnerable parts. Therefore, the lamination crushing equipment is still used in the medium crushing stage. In the medium crushing stage, you can choose a fine jaw crusher or choose the cone crusher of the laminated crushing principle is used for crushing the granite. If the capacity demand is large, it is recommended to use a cone crusher. The cone crusher can feed full material (also called full cavity feeding), and the size of the discharge port can be adjusted in a wide range, which can produce qualified products with uniform grains. (If the particle size requirements of the finished product are not so strict, the stone material broken through the cone crusher can be used as the finished material).
3. Fine crushing stage of granite crushing: through the first two coarse crushing and medium crushing stages, the originally large block granite has been crushed to a particle size close to the size of the finished building aggregate, but if there are requirements for the size of the finished product, or for granite sand making, the crushing operation of fine crushing is also required. This link of fine crushing can be called "shaping and crushing" or sand making crushing. The impact crusher or vertical shaft impact crusher is most suitable for this crushing stage. The choice of these two equipment depends on the demand for the proportion of sand and gravel. If the stone requires a large proportion, then we can use impact crusher for fine crushing. If the sand requires a large proportion, then we use a vertical shaft impact crusher for the final fine crushing operation.
4. Screening and classification stage: After the granite is crushed by the crusher, it needs to be screened. The stone or sand that meets the particle size requirements is transported to the finished material area through the conveyor belt, and the stone that does not meet the specifications is returned to the crusher for crushing again.
This is determined based on the properties and hardness of the granite rock. Granite is a kind of high-hardness rock, which is difficult to crush and wears relatively large to the crusher. Therefore, a reasonable crushing plan is very critical for later production.
Ordinary primary crushing still needs to use jaw crusher, which can crush granite to 10-30cm.
Next, there is a difference between the secondary crushing options. For hard rocks like granite, cone crusher is a more suitable. Currently, single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher are commonly used. You can choose short head type and standard type cone crusher according to different cavity types. Single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher are used together. In this way, although the initial investment is higher, the later operating costs will be much lower, avoiding frequent replacement of parts and maintenance that affect the normal production.
The cone crusher can directly crush different specifications of stone materials such as 5-10/10-15/15-20/20-31.5mm.
If one line needs to produce mechanism sand at the same time, a sand making machine can be added after cone crusher to produce 0-5mm mechanism sand.
The middle is supplemented by supporting equipment such as feeder, vibrating screen, belt conveyor, sand washing machine and so on.
This is a relatively complete granite crushing production line configuration plan, which can be increased or decreased according to actual production conditions.
Granite is a kind of igneous rock formed by the condensation of magma deep underground. The main components are feldspar, quartz and mica. The granite is compact, hard, weather-resistant, wear-resistant and corrosion-resistant. It is a natural building material. However, because the hardness of granite is too high, the requirements for the hard configuration of granite crushed stone equipment are also high, so the equipment must be selected carefully.
Commonly used granite crushed stone equipment is mainly composed of jaw crusher, cone crusher and sand making machine, etc. If the raw material of granite is too large, the jaw crusher should be used for coarse crushing, firstly crush large, hard rock to smaller size, the particle size from the jaw crusher is roughly 10-30cm;
Next, you can use a cone crusher for secondary crushing, they can crush the stone to 5-31.5mm stones;
If you need further fine crushing, you need to choose a sand making machine, which can further finely crush the granite stone after crushing, so that the processed particle size is 1-5mm, which can be directly used as construction sand. Specifically, you can determine how many crushing procedures are needed according to your own situation.
Each series of crushers have different models. The configuration selection of a stone production line needs to be determined according to factors such as output, input and output material size, and then the whole production line quotation can be determined. Only the factor of "100 tons per hour" can not be determined. For selection and quotation of production lines, you can submit other production factors to our 24hour online customer service.
1. There is a large piece of material in the crushing chamber: Since the staff has not cleaned the crushing chamber in time before the previous production, the granite crusher has a large piece of granite. When the crusher starts again, the anchor bolt is subjected to a large shear stress which causes the anchor bolt break.
2. Nut loose: In order to prevent the vibration of the granite crusher, when the crusher is installed, the shock-absorbing plank will be installed underground, but the damper will be rotted due to the long-term burial of the shock-absorbing plank, causing the anchor bolt to loosen, then the granite crusher produced a large forward and backward swing, which eventually caused the anchor bolt to break.
3. Rotor bearing damage: When the rotor bearing is crushing, it will cause serious damage. When the granite crusher is running, the eccentric load will increase, and the crusher will malfunction. Finally, the anchor bolt will break.
In order to prevent the breakage of the anchor bolt, the operator should clean the crushing cavity before starting the crusher, check the nut for looseness at regular intervals and check the wear of the rotor bearing in time.
