(1) raw materials supply
1.1The main raw material of magnesium oxide board :
Magnesium oxide,Magnesium chloride, None-woven fabric, Glass
firber.,Sawdust ,Straws and Perlite
1.2 magnesium oxide warehouse
1.3magnesium chloride solution pool(suggestion uses two dissolve pool and matches mixing equipment)
1.4 pearlite storage(independent) different thickness of the plank use different degree of material.
1.5 sawdust storage(independent) different thickness of the plank uses different degree of material.
2) ingredients,mixing machine
2.1 magnesium oxide measuring: every time weight is 120 kilos.
2.2 magnesium chloride solution's measuring : in the pool magnesium chloride solution is transported to the dozen material platform water tank by water pump. Then pass through metering pump to mixing equipment. Each weight about 140 kilogram. Different plank usage will have adjusted.
2.3 pearlite and sawdust volume ratio of 1:1 or so. The volume is about 0.15 cubic respective.
2.4 mixing equipment: every two minutes to complete a feeding,mixing,feeding process. It needs only one sets machine. Middle material mixing machine is used to complete a feeding,mixing,feeding process every four minutes. It needs two sets machine.
(3) molding equipment,auxiliary equipment( molding section)
3.1 molding equipment: outer size is 25*15*15m. Production speed is twenty meters per minute.
3.1.1 board entranceconveyor belt
3.1.2 material molding
3.2 board exit conveyor belt
3.2.3 cutting (cutting separation area: in normal production conditions, non-stop cutting machine need two people)
3.3.1 board thickness control.
3.3.2 speeding up output board
(4) second maintenance equipment,
4.1 On-the-shelf equipment
4.4.1 bracket car outer dimension is 2.7 meters * 1.5 meters. Every car have 25pcs brackets . Bracket outer dimension is 2.5 meters * 1.5 m * 0.1 meters. Every 7 seconds completed a board into brackets. Every 3 minutes complete a replacement empty bracket car process. Need 1 worker of puting bracket,2 workers of carrying bracket ,2 workers as driver of braclet car. (a elevator of 3 meters * 1.5 meters)
Maintenance workshop need 1000 square meters ,which are ventilated in summer, and insulated in winter.
4.2 off-the-shelf equipment
4.2.1 conveying out board and templates from bracket.
4.2.2 separation area, separated board with templated , board complete stacking by labor,and template delivery into cleaning area. (need some flat cars)
4.3 auxiliary equipment
One boiler: choose big air blower,so that hot air get through maintenance workshop by pipe, make maintenance workshop reaches constant temperature, humidity. Temperature keep in 35-45 degrees , humidity is not less than 100%. Need air flow.
4.3.2 Clearing mold area:Two groups of four workers in charge of clear template, and send cleared template into the molding line equipment.
(5) choosing board, cutting, sealing side, packing,
5.1 cutting equipment: 1 set of cutting machine . Dust catcher and air blower.
5.2 Selecting board: selecting and packing board by labor..
5.3 packing ( counting and packing stacking board, this work need 4 person who will be divided into 2 groups).
Need 4 pcs bubble board pools : 3 meters * 3 meters
Need 1000 square meters bleachery ,which include drying rack (2.28 meters * 6 meters * 0.7 meters so that it can dry 50 pieces of board).
Magnesium board production quantity is based on the number of template.The equipment is the same.
Technology features of fiber cement board production line
There is not any requirement about high temperature and high pressure during production processing.the boarad will be formed at one time after roller-extruding under the conditions of normal temperation and normal pressure .this is a green environmental-protection project, because that there is no waste water ,waste materials and waste gas during its production processing .the finised board don’t need high temperature drying ,air-drying and watering ,and under the normal temperature ,they will dry well indoor.
