Due to no moving parts to solve the reliability problems of work. Product particle size can be controlled to m, in the 100pro. At room temperature,<a href="http://www.christianlouboutinshoesr.com" target="_blank">christian louboutin shoes</a>, crushed under the old lime test, mill studio diameter 300ram, inlet pressure is 0.2MPa (table), flow rate of 450Nm / h, feeding quantity is 300kg / h, feed particle size control in the l0mm,<a href="http://www.edhardymexicos.com" target="_blank">ed hardy mexico</a>, Products Department, through 200 mesh barrier. Scroll with the traditional air jet mill grinder, Third,<a href="http://www.ralphlauren-uk.net" target="_blank">polo ralph lauren</a>, the low crushing system of the system of cold air wave refrigerator j sources are available. The expansion of refrigerator is a refrigerator. from the Dalian University of Technology Promotion Center of cooling air waves, the development of this cooling machine has been successfully used in oil recovery of light hydrocarbon. 1. compressors 2 dryers, | heat exchanger 4 Fan 5. gas weeping refrigerator 6. frozen storage 7. mill glaze powder cold circulating fan heat exchanger 9 10 F refrigerator 11. The second pre-cooling device 12. The first pre-cooling cryogenic comminution system ink Wai Wai l turned the net of 28 * 3 / 1995 is shown for the low-temperature gas wave refrigerator cold source, scroll air mill for the grinding equipment, the use of ammonia as a pre-compression refrigerator cold source, for crushing and recycling the ripple tread rubber chart. l in the air is compressed in the compressor, the dryer 2 to remove water, then after recovery of cold heat exchanger 3, in the compressed gas wave refrigerator 5 to obtain the necessary expansion of the low temperature air, the cold air into the frozen particles positions 6, the frozen particles of the gas after the heat exchanger 3 as a cold source , heat and returned to the compressor 1, and so on. When the frozen particles to positions 6, when the glass temperature, can be crushing operation, into the crushing effect of the gas after the freezing cold in the recovery position 6, the Fan 4 After the heat exchanger 3, further recovery of its cooling capacity, and finally return to the compressor l, the loop continues. crushed powder in storage in the heat exchanger 8, 9 from the air blower to the particles and thus pre-cooling device recovery l1, the pre-cooling particles. in the precooler 12,<a href="http://www.abercrombieukhollister.com" target="_blank">abercrombie fitch uk</a>, the particles by the ammonia compression refrigeration unit cooling capacity provided the first l0 pre-cooling. In this low-temperature grinding system, the distinguishing feature is the matching of cooling capacity is optimized, in accordance with the thermodynamic The basic principle of energy quality and quantity proud to unity, the main high-grade cold glass transition temperature for the establishment of rubber used, low-grade pre-cooling used for the cold. so the whole system from the perspective of thermodynamics is perfect. In This system,<a href="http://www.ralphlauren-danmark.com" target="_blank">ralph lauren outlet</a>, the tread rubber on the crushing test, the tread rubber diameter <6ram, into the jet mill in the gas pressure is 0.2MPa (table), the temperature is a 8012, get all through the 100 mesh powder screen. Fourth, to discuss this device to achieve the tread rubber to smash trials, a number of petrochemical products tested. to be emphasized that the ultimate goal to achieve the waste tire recycling steel. finished steel in the freezer compartment tire broken, isolated from steel wire and cord, crushed fine particles. has been completed in the laboratory in the size of 50 × 50ram wire breakage of the tire off the block, separating the wire and cord, by diameter <10ram of the particles. Pilot goal is to achieve the overall wire broken off the tire. V. CONCLUSIONS 1. the use of air expansion refrigeration technology for low temperature cold source for material, especially waste tire pieces, is economically feasible. 2. refrigerant gas transit machine back pressure for power, jet mill in the scroll to complete the fine grinding of materials is a new attempt, experiments show that the technically feasible. 3 cryogenic grinding system energy use is reasonable and consistent with the requirements of thermodynamics.
