Sand and gravel, as we all know, refer to a loose mixture of sand grains and crushed stones, which is processed from various ores and stones. They are the main building materials for concrete and masonry stones and other structures in basic buildings, roads, and water conservancy projects. However, what are the large-scale crushing machines for the crushing of sand and gravel? How much is one unit?
What are the large crushing machine for stone crushing?
At present, there are various types of large scale crushing machine in the market. According to the different characteristics of sand and gravel, such as stone hardness, compressive strength, and particle size, as well as the different demands of each user for output, output particle size, budget range, and site conditions, a choice should be made based on the actual situation. In comparison, jaw crushers, cone crushers and hammer crushers are currently used and have good effects.
Jaw Crusher
Feeding size：≤1300mm
Production capacity：25-2000t/h
Discharging size：<30mm
Jaw crusher is suitable for sand and gravel materials with compressive strength ranging from 147 to 350 Mpa and is generally used for coarse crushing processing.
Its crushing cavity is deep and there will be no dead zones, which increases the throughput.
Optimize the motion parameters to enable the material to start crushing at the upper part of the crushing chamber, with a larger stroke at the lower part and a greater crushing ratio.
The discharge opening is adjusted by using wedge blocks, and the finished product can be adjusted with uniform particle size.
The integrated structure of the motor base and the main unit makes installation simple and saves space.
Cone Crusher
Feeding size：≤670mm
Production capacity：45-3035t/h
Discharging size：6-70mm
Cone crusher is more suitable for high-hardness sand and gravel materials and is used for secondary crushing and medium/fine crushing.
Through the design of the laminated crushing cavity and fixed-axis structure, the mantle does not require packing and is easy to replace.
The structure has been simplified for easy maintenance and adjustment. A hydraulic cavity cleaning system has been adopted to reduce downtime.
Moreover, each specification of the crusher has multiple cavity types. Users can choose different cavity types according to their different needs to better adapt to their requirements.
Meanwhile, the hydraulic motor adjusts the discharge port, making the operation more convenient and the particle size of the finished product more uniform.
Hammer Crusher
Feeding size：≤1500mm
Production capacity：50-2000t/h
Discharging size：3-60mm
Hammer crusher is suitable for medium-hardness and brittle stone gravel materials, and crushes the materials by the impact of the hammer head.
The modular design, through adjustable movable liners and self-flowing material troughs, enables one-time crushing and molding, reducing the process flow.
The self-flowing trough design avoids repeated crushing, resulting in a small powder production and good particle shape of the finished product.
At the same time, large-sized machines are equipped with hydraulic hammer shaft devices, which facilitate the replacement of hammer heads and hammer shafts, saving time and effort.
What is the price of crushing machine?
The price of large-scale crushing machine is influenced by factors such as equipment type, specification, brand and function. According to the current product information on the market, the price range is usually from several hundred thousand to several million dollar. In addition, it is necessary to consider whether additional costs such as motors, transportation and installation fees are included based on specific circumstances. It is recommended to compare the quotations and services of different suppliers and comprehensively evaluate the cost performance.
