Cryogenic grinding scrap vulcanized rubber tires prepared powder
2016/6/8
The basic principle of cryogenic grinding scrap vulcanized rubber tires powder is prepared in liquid nitrogen L (NZ) as a cold source, the waste tire rubber frozen to a temperature below the glass and crushed, then ground into powder curing. Ground level vulcanized rubber powder is determined on the basis of user requirements on. Thus, the general merchandise sold as powder particle size is 5,1.25,0.4,0.2,0.1,0.05mm range.
National Academy of Sciences of Ukraine Institute of Low Temperature Physics and Engineering, developed by LN: freeze grinding waste tires vulcanized rubber powder preparation technology, the processing route is divided into two parts, crushed and ground, are described below.
A pulverization step
Pulverization step is to scrap the entire rear tires frozen ground, and rubber and steel cord and fiber cords separated, shown in Figure l.
Frozen pulverized powder particle size as shown in FIG.
2, grinding step
Grinding step is pulverized powder were grinding stage, to create a vulcanized rubber powder commercialized, as shown in Fig.
Vulcanization powder particle grinding step shown in Fig.
This waste tire processing line with annual capacity of 10,000 t, waste tire recycling specifications for the 6.00 ~ 12.00, the annual consumption of liquid nitrogen 9000t, where the crushing process 4000t, grinding process 5000t. Its annual output is: vulcanized rubber powder 5000 ~ 6000t, containing 3% rubber, steel 1580t, containing 10% rubber fabric 2300t. The power required for the entire production line: crushing process 50kW, grated step 150 ~ 300kW. Production area of 600m2. Used in the production and processing apparatus shown in FIG.
LN2 cryogenic grinding scrap vulcanized rubber tires prepared powder is characterized by:
(1) The whole waste tires removed stones, after the sediment can be sent directly to the production lines to deal with vulcanized rubber powder (patented technology).
(2) the separation of waste rubber tires, crushed portions of recovery of up to 97%.
(3) with a special jig (patented technology), in the waste tire rubber powder, wire and fiber disposable separated.
(4) micro-mill (patented technology) at low temperatures will be ground to powder ultrafine powder of 0.05mm.
(5) the production process based physical processes at low temperatures, without any chemical change. Therefore, a better solution to the problem of environmental pollution.
(6) sulfide powder obtained good quality.
(7) The finely pulverized vulcanized rubber powder (particle size of not greater than 0.2mm), without chemical modification, even when mixed with a larger amount (about 20%), which will remain high vulcanizates physical properties.
(8) LN: greater consumption. Which is the inadequacy of the production method.
