Description
Technical field
The present invention relates to Paper-faced gyp plate technique, particularly relate to a kind of recovery and treatment method and device of Thistle board.
Background technology
At present, waste paper surface gypsum board all to be recycled, to reach the object reducing environmental pollution and the wasting of resources taking appropriate measures by domestic and international plasterboard enterprise.Wherein, the recoverying and utilizing method of Thistle board mainly contains the following two kinds: one is burnt by waste gypsum plate, to remove outer field mask paper, then waste gypsum is broken, re-use again, but this method can not utilize outer mask paper, and burning can pollute; Another kind is that plasterboard is carried out fragmentation procedure, and then is separated with mask paper by gypsum core, is then reused for manufacture plasterboard, both decreases environmental pollution like this, can reduce production cost again.
Accordingly, for above-mentioned recoverying and utilizing method, also in succession have developed special plant equipment both at home and abroad to realize the recycling to waste gypsum plate.As the U.S. adopts GYPchipper, its grinding mode is that single axle turns round pin pulverizing of charging, and grindability is 2.5t/h.Japan is developed into the pulverizer be suitable at building site process waste gypsum plate, i.e. brave formula cutting machine, and its grinding mode is that twin axle revolution engagement blade is pulverized, and grindability is 1.5t/h.The gypsum recovery system of the subsidiary EGRS company designs exploitation of Ireland Enviro Grind group is made up of vibratory sieve, mill and belt feeder.Waste gypsum and waste gypsum plate pulverize by this technique, be separated mask paper, and gypsum is crushed into powder, can again be applied to gypsum board industry, agriculture field and cement industry etc., this system is applicable to any industrial circle that there is waste gypsum product in domestic and international market.
At present at home, the equipment of building site process waste materials also has corresponding development, as the small-sized beater grinder of PS-Ф 380*280 that Changzhou building machinery repair shop manufactures and designs, atwirl hammer is utilized to pulverize waste gypsum plate, it is only applicable to fritter sheet material and waste material etc., and grindability is 1t/h.BeiXin Group Building Material Co., Ltd have developed kibbler roll together with some other auxiliary equipment with the use of, to waste gypsum plate carry out fragmentation reclaim.Auxiliary equipment mainly contains ribbon conveyer, belt conveyor, vibratory sieve, dust-precipitator etc.Can according to the situation in existing place and use the situation of equipment to carry out technology arrangement.The operation principle of this system is that waste gypsum plate fragmentation is rolled into particle and recycles by roll-type profile of tooth disintegrating machine, and breaking capacity is about 2.5t/h, respond well, decreases the impact on environment.Zhaoqing Bei Xin building materials Co., Ltd have employed shear crusher, waste paper surface gypsum board is shunted in the space of rotor and stator tooth plate through material distributing cone equably, material is broken by the extruding of dynamic rotor tooth plate and rotor tooth plate and shearing, material after fragmentation and the material of pre-screen are discharged by bottom disintegrating machine, breaking capacity is about 2.5t/h, and the method can by broken for the gypsum of the mask paper of flexibility and fragility.
Waste gypsum plate is mainly divided into two classes, and one is the plasterboard of normal width, and two is small piece plate (gypsum filler strips etc.).Comprehensive treatment process both domestic and external, main employing one step breaking method process waste gypsum plate.If only adopt a step crush method process, the paper after fragmentation and Separation of gypsum are thorough, can not be directly used in production to reclaim to use, and need to increase mill in follow-up raw material production equipment and screening plant ability is pratical and feasible.
