Embodiment Construction

[0030] figure 1 The tire shredding system 10 shown essentially consists of a tire feeding assembly 11 comprising a metering device 11 a and a feeding device 12 . The outlet 1 of the tire feeding assembly 11 is connected with a first crusher 13, which pre-cuts the incoming waste tire raw material to a certain particle size, and after the crusher 13 is a separator 14, which 14 Separation of inorganic components and water.

[0031] A conveying device 15 conveys the coarsely crushed material via a distribution device 16 to the second crushers 17 and 17a. The distributor 16 is bidirectionally rotatable so that the lower two parallel crushers 17 and 17a can be evenly loaded.

[0032] Alternatively, the pre-shredded material loaded onto the conveyor 15 comprises scrap tires or a plastic-metal-fibre mixture.

[0033] The crushers 17, 17a are followed by sorting units 18 and 18a and the sorted material is fed to separators 19 and 19a which separate exposed steel, fibrous reinforceme...

Abstract

Plant for the processing of spent rubber and spent rubber products by cryogenic size reduction, comprising freeze tunnels for freezing the material stock to be reduced, foreign material separating means and reducing means for the deep-frozen material. To this end, a multi-stage pre-reducing system comprising reducers (17, 17a) is provided. The pre-reduced material stock is directed through a freeze system divided into a plurality of freeze zones in which a low-temperature liquid refrigerant may be sprayed onto the material stock. The freeze system has a temperature equalizing system connected to the output thereof, and the deep-frozen material stock is comminuted to a fine grain size in a step-wise fashion in subsequent multi-stage fine reducers.

Description

technical field [0001] The present invention relates to an equipment for treating waste rubber and used rubber products with multi-stage low-temperature crushing, which includes a freezing device for freezing materials to be crushed, a foreign matter separating device and a screening device. Background technique [0002] Scrap car tires and industrial rubber product waste are rich sources of raw materials. This continuous increase in the amount of waste and waste material places a considerable burden on the environment. The principles of the recycling economy and for the reduction of CO 2 Recycling of used car tires and rubber product waste has become even more important as a result of worldwide efforts to reduce emissions. [0003] For example, German patent document DE 39 15 984c1 discloses a plant for processing eg recycling waste rubber. The problem is that the vulcanized raw rubber is not softened by heating, but carbonized. This existing equipment uses a refrigerat...
