the river pebble is a kind of pure natural stone. it is taken from the sandstone mountain produced by the uplift of the ancient riverbed after the crustal movement that occurred thousands of years ago. it has experienced continuous crushing and friction during the flooding and running of water. the main chemical component is silica, followed by a small amount of iron oxide and trace elements such as manganese, copper, aluminum and magnesium.
during the evolution of vicissitudes of tens of thousands of years, they have suffered from the wave-washing movement, and they have lost irregular edges and corners by gravel collision friction. the surface is smooth and clean, the average content of sio2 is 85%, and the highest compressive strength can reach 300mpa or more. it is more than 7 degrees mohs, and has good pressure resistance, wear resistance and corrosion resistance. it is an ideal widely used mechanism sand material.
pebbles are particles formed by natural conditions of rocks. they can be divided into river pebbles, sea pebbles and mountain pebbles. they are accessory products of sand mining and the pebbles are pure natural building stones. the pebbles are mostly round, smooth and various colors. they are used in courtyard rockery, pavement, bonsai filling materials, garden art and other buildings.
in addition to being used in public buildings for its beautiful appearance, they can also used to be cushion filter material in supporting layer of mechanical filter because of its specific surface area and high mechanical strength. and pebbles are good auxiliary materials for ceramics, precision casting, papermaking, spraying, chemical industry, monocrystalline silicon, national defense, etc.
pebble resources are very rich. there are many kinds of pebbles with different characteristics and various forms in the world. the processing and application of pebbles has always been a hot spot. they take advantages of hard quality, compression resistance, wear resistance and corrosion resistance, which can be good green building material welcomed by sand and stone market.
at present, there are many crushing equipment for crushing river pebbles on the market. for high-quality river pebbles, crushing equipment cannot be selected at will, equipment is not suitable, not only cannot bring high yield, but also cause the service life of the equipment itself to decline, subsequent production costs the increase of high-hardness stone such as broken river pebbles, it is best to use the following crushers.
1. jaw crusher
the crushing ratio of the jaw crusher is large, and the large-scale granite that was originally mined can be crushed to medium grain size by the jaw crusher at one time, which is convenient for processing in the next process. more than granite, many stone production lines will use the jaw crusher as a piece of crushing equipment. the equipment has good wear resistance, high crushing strength, and the same amount of stone material, with less wear and reasonable component design.
2. impact crusher
the impact crusher is broken by impact energy, and the crushing angle is reasonable and has a shaping effect.
3. cone crusher
the cone crusher can break the medium-grained granite into small particles and more uniform granite. the cone crusher crushes the granite by bending and extrusion. the crushed granite has a more uniform grain shape and is laminated. broken, the finished grain shape is more excellent.
in the pebble stone crushing plant, vibrating feeder is used to feed the raw river pebble into jaw crusher for crushing. jaw crusher is the primary crushing equipment to crush the river pebble into smaller sizes. cone crusher is the secondary crushing equipment to crush the river pebble into required sizes for sand making. vibrating screen is used to separate the particles discharged from cone crusher and send the large ones back to cone crusher for re-crushing.
the pebble is always processed into artificial sand materials for the construction application. if you want to reach this production purpose, it will need the sand making machine to realize. after cone crusher working, the sand making machine will further processed the crushed pebbles into building usage materials.
pebble sand making machine is the new type equipment produced by kefid. its function is to reshape the building stones, process the stone materials into artificial sands. with the function of sand making machine, it can save much more energy and it will produce high quality and desired shape construction sands materials.
kefid is a professional large-scale mining crushing and screening plant manufacturer, dedicated to the independent research, production and sales of ore processing equipment. according to the configuration, the price will vary. kefid can customize pebble crushing production line according to customer’s demand for productivity, input size, output size, moisture etc. to better meet the requirements in practical application so that unnecessary devices can be canceled to lower investment cost.
there are many types of river pebble stone crushers. they have different prices. the specific quotation is also different depending on the configuration. therefore, please contact our 24hour online customer service. we will recommend the appropriate type of river pebble stone crusher according to your processing requirements and then quote.
this site is located in russia. it uses three stage crushing. pebble are crushed by jaw crusher primarily, and then it goes into cone crusher for secondary crushing. sand making machine will shape the stones and unqualified aggregate should be reprocess in the previous process. finally the products will be packed and used in road construction.
