Ceramsite sand, also known as petroleumfracturing proppant, is a new type of material that uses bauxite, manganesepowder and admixture as raw materials, which are crushed, dried, compounded,balled, calcined, cooled and sieved. . Ceramsite sand has the advantages ofhigh strength, pressure and wear resistance, high roundness, shock resistanceand good permeability resistance.
Ceramsite sand production process
The bauxite with a particle size of300-500mm will be crushed and sent to a boiling furnace dryer for drying, andthen with manganese powder, admixture, etc. through the batching station, intothe grinding system with high efficiency vortex separator. The raw materialpowder with a fineness of 400 mesh or more is a new granulator developed byZhengzhou Mining Machinery. After adding water, the raw material powder is madeinto pellets with acceptable particle size.
The pellet enters the dryer set at the end ofthe kiln, uses the waste heat of the kiln exhaust gas to reduce the moisture ofthe pellet, and then passes through the sieve to enter the rotary kiln forcalcination. The calcined ceramsite sand is cooled by a single cold machine andsieved through a cylindrical sieve. The qualified different particle sizes arepackaged and shipped, and the unqualified pellets are returned to the grindingsystem.
Available heat source
The fuel calcined in the rotary kiln can befresh water, electric power, natural gas solid fuel or the like.
Outstanding advantages of ceramsite sandproduction line:
1. Advanced equipment: The ceramsite sandgranulator developed by Henan Zheng Mine Machinery Co., Ltd. is a specialequipment for granulation in the ceramsite industry. It has high productionefficiency, full automation control and no dust pollution.
2. Granulation experiments can be carriedout: Zheng Mine Machinery has a complete set of granulation experimentalproduction lines, which can conduct experiments on the incoming materials ofcustomers, find out the granulation process of the materials, and give guidanceto actual production.
3. Environmental protection andpollution-free: The dust removal system of the petroleum ceramsite productionline of Zheng Mine Machinery adopts the design of automatic control system, andthe dust removal effect reaches the national standard.
