Sandstone is a kind of sedimentary rock, mainly composed of quartz and feldspar. Whether it is strength or grain type, it is one of the good raw materials for machine-made sand. In addition, its advantages such as outdoor weathering, non-melting in water, moisture resistance, and sound absorption are good buildings one of the decoration materials. Sandstone made of machine-made sand has the advantages of natural sand, and it also has the combination of artificial sand technology. The finished product has sharp and angular grains. It is used in the construction industry or bridge construction. It has higher safety, no cracks, and anti-extrusion, anti-corrosion, etc. advantage. Common gravel crushers include jaw crushers, impact crushers, cone crushers, and mobile crushers. Because various sand and gravel crushers have their applicable sand and gravel, and the crushing effect is also different, the quotation of each equipment will also be different. Sandstone into building stones must go through the production process of crushing, sand making, screening and other production processes. A complete set of crushing production lines need to be reasonably matched to achieve low investment and high efficiency. According to the characteristics of sandstone, sandstone into building stones should be prepared as follows equipment:
1. Jaw Crusher
Feeding particle size: ≤1360mm
Processing capacity: 50-1500t/h
Performance characteristics: The jaw crusher has a large feed size, which can be used for primary coarse crushing of raw materials; the integrated installation structure of the main machine and the motor is firm and reliable, and the footprint is small; the wedge-type discharge opening adjustment method realizes step less adjustment, to reduce the labor intensity of workers and downtime; the large inclination bracket design makes the lower stroke of the cavity larger and higher output.
Feed size: <1000mm
Processing capacity: 50-1200t/h
Performance characteristics: used for crushing soft ore (limestone, etc.), the finished product has good grain size and less powder, and is mostly used in small and medium stone factories, but cannot be used for sand making; the user can adjust the gap between the impact board and the hammer to control the output material granularity: The new high wear-resistant materials are used in large quantities, and are equipped with a variety of safety lock devices to extend the service life, improve safety performance and save costs.
Feed size: ≤560mm
Processing capacity: 45-2176t/h
Performance characteristics: cone crusher is mainly used to crush hard materials, and has large production capacity and high crushing efficiency. It is suitable for large stone factories; it has iron-pass protection and automatic cavity cleaning functions, which are stable and reliable; components can be disassembled from the upper and side, which is convenient check and repair; the price is slightly expensive, but the use cycle is long, and the automatic control system can easily realize remote control.
Feed size: ≤1500mm
Processing capacity: 250-2000t/h
Performance characteristics: suitable for crushing limestone and medium-hard ore with compressive strength lower than 200Mpa; sledge hammer head, dual power, satisfying larger production capacity; one-time forming, no secondary crushing process, suitable for users with small working sites. At the same time, it reduces the purchase of other crushing equipment and saves investment costs.
Feed size: ≤240mm
Processing capacity: 8-500t/h
Performance characteristics: used in the fine crushing and shaping of minerals and rocks in a variety of metal and non-metal mines, refractory materials, abrasive ceramic raw materials, building materials, high-speed railway construction, water conservancy and hydropower construction, and civil sand and gravel aggregate production, especially for centering hard, extra-hard or abrasive materials, such as sandstone, granite, basalt, silicon carbide, emery, alumina, magnesia, etc. are more superior than other equipment. It has two crushing principles of "stone beat stone and stone beat iron", sharing a set of crushing cavity; equipped with hydraulic lifting opening device, manual or electric hoist, convenient for maintenance; equipped with PLC automatic control and monitoring system, high safety performance and convenient monitoring.
