Detailed Description
Brief introduction
Rock wool is a kind of vitreous fiber that gets from slag, basalt, limestone and dolomite through fusion and fiber forming technique. It has good thermal and sound insulation property and widely used in building industry, chemical field, textile industry and many other fields.
Production process
The rock wool production line is a complete set of machinery. The melting furnace is located at the beginning of the line which will melt the raw material into lava. Then the centrifuge will transform the lava into thin fiber. Under the blowing of high pressure air, the fiber will enter the wool collector and become primary rock wool blanket. The pendulum will accept the blanket and make it fold to multi-layer blankets on the forming conveyor. Then it will be compressed in the pleating machine and be cured in the curing oven. Next it will be cut by the longitudinal and cross cutter according to the specified dimension and become the final products, such as boards, blankets.
Equipment introduction
Melting system
This production line could adopt tank furnace with natural gas or heavy oil as fuel. They could ensure reliable melting performance and continuous operation.
Fiber forming system
The main equipment in this system is the four-roller centrifuge. It could transform the high temperature lava into thin fiber with the centrifugal force produced by the high rotating rollers.
Wool collecting system
This system could collect fiber under the negative pressure of the air-intake fan and allocate the raw blanket stably and equably to form multi-layer blanket.
Wool allocating machine
It could allocate and convey the raw blanket from the pendulum and also act as the transition part to connect each production process.
Compression pleating machine
It will prepress the blanket and then send it into curing oven. It could improve the strength and tearing force of rock wool and also reduce the burden of the curing oven.
Curing oven
It could cure and shape the rock wool to form rock wool board or blanket with certain density and width.
Cooling conveyor
Its function is to make the product cool and convey the product to the next process.
Cutting system
It could proceed longitudinal and crossing cutting to make required products.
Packing machine
The packing machine is used to pack the rock wool board with one layer of shrinkage film, in order to facilitate the transportation and loading.
