低温粉碎的另种粉碎的方式及作用

低温破坏是运用液氮冷冻,使废旧橡胶制品冷至玻璃化温度以下,然后用锤式破坏机或辊筒破坏机破坏。低温破坏具有两种办法,即直接冷冻低温破坏法和在冷冻条件下先粗碎再细碎的低温破坏法。
Low temperature damage is to use liquid nitrogen to freeze waste rubber products to below the glass transition temperature, and then to use hammer or roller damage machine to destroy. There are two methods for low-temperature damage: direct freezing low-temperature damage method and low-temperature damage method of crushing first and then fine crushing under freezing conditions.
直接冷冻低温破坏法。这种破坏法的出产过程是在轮胎解剖机上将轮胎的胎圈部位切下,一起将胎面分割成2一3小块,置于冷冻(液氮)设备内,然后用锤式或辊筒式破坏机破坏,然后得到胶粉。
Direct freezing low temperature damage method. The production process of this destructive method is to cut the bead part of the tire on the tyre dissector, divide the tread into 2-3 pieces together, put them in the freezing (liquid nitrogen) equipment, and then destroy them with a hammer or roller destroyer, and then get the rubber powder.
在冷冻条件下先粗碎再细碎的低温破坏法。这种破坏办法的出产过程是:按将废旧轮胎切割后,置于冷冻设备内,在锤式或辊筒破坏机内先粗碎,粗碎后再次冷冻,再细碎,然后得到胶粉。这种出产办法因需要经过两次液氮冷冻,故出产成本较高。但用该法处理钢丝子午线轮胎时,钢丝易和橡胶分离,一起可相应减少动力耗费。
Low temperature destroy method of crushing first and then fine crushing under freezing condition. The production process of this destructive method is as follows: after cutting waste tires, they are placed in refrigeration equipment, crushed first in hammer or roller destroyer, then frozen again, then finely crushed, and then obtained rubber powder. This production method needs to be refrigerated twice by liquid nitrogen, so the production cost is higher. But when this method is used to treat steel radial tire, the steel wire is easily separated from rubber, and the power consumption can be reduced correspondingly.
据悉,风冷式低温破坏机在高速运转过程中会产生高温,在破坏热敏物料时会因温度高而蜕变,那么就需要对破坏机进行降温,而济南市胜灵机械制造有限公司研制出产的wf-30风冷式低温破坏机选用冷风机向破坏仓注入冷风以完成降温的作用(凉气温度可调),使物料不会因温度高而蜕变。物料进了破坏机内被破坏到所需的细度(粒度巨细可经过更换筛网进行调理)。该产品可广泛用于制药、食品、化工、国防科研等行业的物料破坏,特别是热敏感性物质和无法破坏的物料。

It is reported that the air-cooled cryogenic destroyer will produce high temperature in the process of high-speed operation. When destroying the heat-sensitive material, it will change because of the high temperature. So it is necessary to cool down the destroyer. The wf-30 air-cooled cryogenic destroyer developed by Jinan Shengling Machinery Manufacturing Co., Ltd. chooses a cold fan to inject cold air into the destroying warehouse to complete the cooling effect (the temperature can be adjusted), so that the material can be cooled. It will not change because of the high temperature. Material is destroyed to the required fineness when it enters the destroyer (the size of the material can be adjusted by replacing the screen). The product can be widely used for material destruction in pharmaceutical, food, chemical, national defense and scientific research industries, especially for heat sensitive materials and materials that can not be destroyed.
低温破坏工艺具有不可替代的作用
Low temperature damage process plays an irreplaceable role
低温破坏技能并非新技能,早在1948年便已经完成工业化,在废橡胶、塑料、食物、制药等的回收运用方面已有相当长的研讨历史,并具有较为成熟的技能和工艺,开展低温破坏工艺研讨十分必要而且有意义。据悉,低温破坏工艺具有多个优势。
Low temperature destructive technology is not a new skill. It has been industrialized as early as 1948. It has a long history of research on the recycling and utilization of waste rubber, plastics, food, pharmaceuticals, etc. It has mature skills and processes. It is necessary and meaningful to carry out low temperature destructive technology research. It is reported that the low temperature damage process has many advantages.
1、最适用于破坏常温下不易破坏的物质,如橡胶,热塑性塑料等;
1. It is most suitable for destroying non-destructive substances at room temperature, such as rubber, thermoplastics, etc.
2、内装的分级机能够得到显着的粒径分布粉体资料;
2. The inner classifier can obtain remarkable particle size distribution data.
3、较常温破坏可得到更细、流动性更好的胶粉,破坏后的粉体成型性好;
3. Finer and more fluidity rubber powder can be obtained by breaking at room temperature, and the powder after breaking has good formability.
4、可防止粉尘、臭气污染与噪音;
4. It can prevent dust, odor pollution and noise.
5、破碎所需的动力很低,能够提高破坏机产值;
5. The power required for crushing is very low, which can improve the output value of the destroyer.
6、破坏热敏性物质不会受到氧化作用与热而蜕变;
6. Destroying thermosensitive substances will not be oxidized and transformed by heat.
7、运用各种物质低温脆性之差异,可对复杂物作选择性破坏,如含橡胶、金属和纤维的轮胎。
7. The difference of low temperature brittleness of various materials can selectively destroy complex materials, such as tires containing rubber, metal and fibers.
高分子资料橡胶作为常温下的高弹性资料,经过降低温度,使其呈脆性物质,并在坚持低温的破坏机内破坏,可得到抱负的破坏作用,这是其他破坏办法所不能替代的。
Polymer material rubber, as a high elastic material at room temperature, can be destroyed by lowering the temperature, making it brittle and destroying it in the destroyer insisting on low temperature, which can not be replaced by other destroying methods.
低温破坏在中药破坏过程中起着重要作用,如无污染性,此类设备在破坏过程中破坏室内的温度一般都在零度以下,呈无污染状况;适用范围广,无论何种物料,不管物料的成分和性质,此类破坏机都能达到制药工艺要求。但是低温破坏机也由于破坏成本高,平常运用较少。
Low temperature damage plays an important role in the process of destruction of traditional Chinese medicine, such as pollution-free, such equipment in the process of destruction indoor temperature is generally below zero, showing a pollution-free situation; the scope of application is wide, no matter what kind of materials, regardless of the composition and properties of materials, such destroyers can meet the requirements of pharmaceutical technology. But the low temperature destroyer is usually used less because of the high cost of destroying.
