Rock Wool Production Line

Brief introduction

Glass wool is a kind of insulation materials which is made of natural ores, such as quartzite, dolomite, feldspar, limestone and so on. With the features of low density, fireproof, thermal insulation, the glass wool has found a wide utilization in the fields of petrochemical industry, architecture, etc.
The capacity of the glass wool production line is 2000-20000 tons per year. The raw material is cullet, feldspar, dolomite, calcined soda, borax, limestone, others. The fuel could natural gas or heavy oil, etc.

Production process
The glass wool production line is a complete set of machinery. The raw materials added with auxiliary agents such as calcined soda and borax are melted into glass fluid in the tank furnace. The lava is drawn, blown or thrown into very thin fibers under centrifugal force of the spinner. The forming fiber will be collected to be original blanket by wool collecting machine. The original felt is sent into the curing oven to be solidified and shaped by the conveyor. After curing, the products will go through the cooling section. It will be cut by slitting cutter and cross cutter according to the setting length. Finally, it will become the final products such as board, blanket.

We could provide a series of service including the project consultancy, technical support, installation and commission, employees training, system maintenance, technology upgrade, etc. we warmly welcome you to visit our company.

Equipment introduction
Melting system
This production line adopts tank furnace which is made up of different refractory materials and uses natural gas as fuel.
Fiber forming system
Centrifuge could produce glass wool fiber from vitreous fluid. It is the key equipment of the whole production line and decides the quality of the final product.
Glass wool collector
Glass wool collector could collect fibers into crude felt which is then sent to curing oven via the transition conveyor.
Curing oven
Curing oven could heat and shape glass wool layers containing binder as per the density, size required for products. It could make binder and fibers polymerize into one, producing glass wool blanket and board.
Conveying and cutting machines
The conveying machine could convey the cured glass wool products to the cutting system and cool the products at the same time.
The cutting system could proceed longitudinal and crossing cutting to make required products.
Blanket / felt-rolling machine
It could roll the glass wool blanket into rolls and facilitate the packing of product.

Brief introduction
Ceramic Fiber, also called aluminum silicate fiber, it is a kind of light weight refractory fiber. It possesses the performances and advantages of high temperature resistance, light, excellent thermal stability, low heat conductivity, small thermal capacitance and mechanical vibration resistance etc. The ceramic fiber needled blanket is the main products of ceramic fiber, it has higher tensile strength and other excellent features. As refractory material, it has found an increasingly wide utilization in the fields of in metallurgy, cement, glass industry, etc.

Production process
The complete ceramic fiber production line adopts electrical resistance furnace to melt the raw material (such as calcined kaolin clay, alumina, silica, zirconia, etc) into lava. Then the three-roller centrifuge will attenuate the molten fluid into fibers under the centrifugal force of the high speed rotational rollers to the lava. The crude blankets are formed in the collecting chamber and then carried out from the setting chamber. After going through the allocating conveyor, the crude blankets enter into the sintering furnace to be cured. Then the double-layer needling machine will needle the blanket to make the fiber layer tightly interweave with each other. Then after longitudinal and cross cutting, rolling, the crude blankets will become the needled blanket.

Equipment Introduction
Melting system
The electric resistance furnace could use the current generated between the electric resistances to melt the raw materials.
Fiber forming system
The fiber forming machine is three-roller centrifuge. The high temperature melting fluid will be dispersed and stretched into thin fibers by the centrifugal force of high speed roller.
Wool collector
The wool collector is used to collect the fibers into crude blanket. The fibers are evenly drawn on the mesh belt under the function of negative pressure air and become crude blanket.
Needling machine
Needling blanket is developed from the non-woven needling technique. The needle hooks move up and down and draw the fibers to make the fiber layer tightly interweave with each other. This process could improve the tensile strength and the wind erosion resistance performance of the blanket.
Sintering furnace
It could burn off the lubricant in the blanket and make fiber microcrystalline processing to achieve the heat shaping of the blanket and reach the required thickness and dimension.
Cutting and rolling system
This system is used to finish the cutting and rolling of the blankets. The blankets will be cut into pieces or strips and rolled into rolls according to the proceeding requirement.
