Description
Technical field
The present invention relates to the recovery and treatment method and device of Paper-faced gyp plate technique, more particularly to a kind of Thistle board.
Background technology
At present, domestic and international plasterboard enterprise is all recycled waste paper surface gypsum board taking appropriate measures, with
Reach the purpose to reduce environmental pollution with the wasting of resources.Wherein, the recoverying and utilizing method of Thistle board mainly has the following two kinds：
One kind is that waste gypsum plate is burnt, and to remove the mask paper of outer layer, is then crushed waste gypsum, then is re-used, still
This method can not utilize outer layer mask paper, and burning can pollute；Another kind is that plasterboard is carried out into fragmentation procedure, is entered
And separate gypsum core with mask paper, then it is reused for manufacturing plasterboard, had so both reduced environmental pollution, and can reduces life
Produce cost.
Accordingly, for above-mentioned recoverying and utilizing method, special plant equipment is also have developed in succession both at home and abroad to realize
Recycling to waste gypsum plate.As the U.S. uses GYPchipper, its grinding mode is that single axle revolution is charged pin crushing, powder
Broken ability is 2.5t/h.Japan is developed into suitable for the pulverizer in building site processing waste gypsum plate, i.e., brave formula cutting machine, its powder
Broken mode is that twin axle revolution engagement blade crushes, grindability 1.5t/h.The son of Irish Enviro Grind groups is public
The gypsum recovery system that EGRS companies of department design and develop is made up of vibratory sieve, mill and belt feeder.The technique is by waste gypsum and barren rock
Cream plate pulverizes, and separates mask paper, and gypsum is crushed into powder, can re-apply in gypsum board industry, agriculture field and
Any industrial circle of waste gypsum product suitable for domestic and international market be present in cement industry etc., the system.
At present at home, the equipment of building site processing waste materials also has corresponding development, as Changzhou building machinery is repaired
The small-sized beater grinders of PS- Ф 380*280 that factory manufactures and designs, waste gypsum plate is crushed using atwirl hammer, it is suitable
For fritter sheet material and waste material etc., grindability 1t/h.BeiXin Group Building Material Co., Ltd have developed kibbler roll
It is used cooperatively together with some other auxiliary equipment, broken recovery is carried out to waste gypsum plate.Auxiliary equipment mainly has belt conveying
Machine, belt conveyor, vibratory sieve, dust-precipitator etc..According to the situation in existing place and the situation progress technique of equipment can be used
Arrangement.The operation principle of the system, which is roll-type tooth form disintegrating machine, to be rolled into waste gypsum plate is broken particle and recycles, is crushed
Ability about 2.5t/h, works well, and reduces the influence to environment.Zhaoqing Bei Xin building materials Co., Ltd employs shearing broken
Machine, waste paper surface gypsum board are equably shunted in the space of rotor and stator tooth plate by material distributing cone, and material is by dynamic rotor tooth
The extruding and shearing of plate and rotor tooth plate and crush, the material of material and pre-screening after crushing by broken motor spindle discharge,
Breaking capacity about 2.5t/h, the method can crush the mask paper of flexibility and brittle gypsum.
Waste gypsum plate is broadly divided into two classes, when the plasterboard of normal width, second, small piece plate (gypsum filler strip etc.).It is comprehensive
Handling process both domestic and external, mainly using step breaking method processing waste gypsum plate.If only with step crush method processing, break
Paper and Separation of gypsum after broken be not thorough, it is impossible to is directly used in recovery in production and uses, it is necessary to be set in follow-up raw material production
Standby middle increase mill and screening plant are just pratical and feasible.
