Artificial sand making process and sand making machine sale
Artificial sand is to point to in addition to the soil treatment mechanism sand, mixed sand. Mechanism of sand is made up of a mechanical crushing, screening scale, particle size of rock particles less than 4.75 mm, but not including soft rock, weathering rock particles.
Professional Sand manufacturer
XSM is professional sand making machine manufacturer in the world.We hold the world’s most advanced technology sand making machine.
VSI series efficient shaft impact crusher, sand making machine, commonly known as plastic machine, is the introduction of our German experts the latest research achievements, and combining with the Chinese mining conditions improved design, is currently the most advanced world level of the fourth generation high performance sand making equipment.
VSI Shaft Impact Crusher
VSI Shaft Impact Crusher Advantages:
Processing a large quantity of uniform size:
The maximum throughput of up to 520 tons / hour, compared with the traditional equipment and under the same power, the yield increased by 30% and stable. The product of a cube, grain shape, reasonable distribution, fineness modulus can be adjusted, especially suitable for artificial system sand and stone plastic.
The vulnerability of low energy consumption and long service life:
The optimal design of crushing cavity impact angle, friction material and wear resistant parts, directly reduces the equipment costs; with the German original thin oil lubrication station, completely solve the problem of the spindle bearings, bearing temperature is constant, the maintenance cycle and service life extension
Artificial sand source
River sand in construction has many advantages, but with the increase of building the indicators, natural sand because of difference of regional distribution and the natural weathering generated conditions, and presents the physical and chemical index volatility, for concrete, especially the high performance concrete is not conducive to the stability of quality.In fact, through artificial sand natural sand can solve these shortcomings.And due to the decrease of river sand, artificial sand is not only solve the problem of the lack of natural sand, as well as important raw materials of high quality concrete.
Wet process production technology
Proportional control system of sand raw materials for making a system turns to size 5 ~ 40 mm to aggregate sand control warehouse, through vibration feeder for rod mill feed.Rod mill is the core equipment of wet sand of legal system, as the center row cylindrical rod mill.Materials and water from entering on both ends of the cylinder, cylinder is equipped with about 30 tons of different diameter steel bar, the cylinder rotates, material grinding between steel bar and broken, broken after discharge from the cylinder center, together with the water into the spiral classifier, cleaning, grading in the blade agitation.Stone making system of 5 mm or less (or 2.5 mm) or less sand also entered the “rod mill” (the number of small or enter the “spiral classifier”).Qualified sand into the sieve dehydration dehydration after the pile of sand fill, output to the finished product fine particles of mud (powder) with water.
Dry process production technology:
because of the wet legal system the problem of large water sand, dry production process has been put forward in many years ago, because of the limitation of dust recovery processes have not been able to get promotion and application of hydropower system has a small amount of application in recent years.
Dry process finished product there are two sources of sand, stone system is a system of 5 mm or less part, 2 it is sand sand making system in the production of finished products.Sand making system of raw material for the stone turn ratio control system for grain size 5 ~ 40 mm to the aggregate of sand control warehouse to vertical shaft impact crusher feed through vibration feeder.Vertical shaft impact crusher is the core equipment of dry sand of legal system, vertical shaft crusher is divided into stone.
Two type iron and stone hit stone, sand system USES is stone type while the iron is hot.Rotor material along diameter direction left out, hit the cavity back plate to get broken.Due to the vertical shaft broken products are not completely sand, must be the lie between screen to > 5 mm material returns to the bunker, a closed cycle to repeat.
Semi-dry method and arrangement of the wet process and dry process of two systems, both legal system played a dry sand production capacity of large, the advantages of low production cost, and to some extent, solve the problem that the fineness modulus adjustment.Due to the arrangement of both the wet and dry process of the two systems.In the early construction into a larger production by wet process.Finished product distribution regulation of sand storehouse comes from three parts: all the way to be a part of the stone coal system 5 mm or less, the second is the final product of the system of vertical shaft broken sand sand, three is the final product of the mechanism of rod mill sand sand.Finished product sand the main sources of dry sand system, legal system because of using the system production cost is low.Wet sand system of legal system is mainly used to adjust the fineness modulus or grading.Half the characteristics of the dry process production technology is the initial construction investment is larger than other two methods, but the production cost is relatively low, especially when big sand production volume.Hydropower system sand aggregate demand at ten million tonnes, or tens of millions of tons, total cost saving is very obvious.But it belongs to the disadvantage of dry process production is also very prominent.
