Tire Recycling

http://finance.yahoo.com/q?s=TXMC.PK

The Tirex Corporations TCS System is a state-of-the-art tire reduction system which uses a patented fracturing unit in combination with a proprietary freezing process which does not require liquid nitrogen to produce crumb rubber of exceptional purity and quality.

Depending on market requirements, the crumb rubber output can be further reground in a secondary operation for further rubber size reduction, if necessary. The process is designed to receive whole tires and, through the various stages of the process, effect their separation into their individual components.

Below is a qualitative description of the Tirex TCS Operational Process:

SECTION 1 Tire Inventory Control, Tire Pre-Inspection and Sorting Station

This is not part of the TCS per se; this section is needed to control incoming tires from supply sources and truck offloads in a temporary storage area where tires can be inspected and sorted.

Inventories of tires should be maintained at a level commensurate with daily consumption and including a buffer based on the established minimum quantity to be able operate for some duration of time (e.g. 2-3 days) in case regular tire supply is interrupted, or perhaps as a function of the local codes and regulations applicable to the plant location.

Operators feed the pre-inspected tires by conveyor from the receiving area to the initial TCS-1 section, the Tire Preparation Unit.

SECTION 2 Tire Preparation Unit

Whole tires, after inspection, will be put through a rasper or a shredder to reduce the tire into pieces that will then be fed into our freezing chamber

SECTION 3 Air Plant

The Air Plant cools air to approximately 1230 C by successively compressing, cooling and expanding ambient room air. It requires human intervention at start up but is otherwise run by computer, eliminating the need for operator presence. The cold air goes directly into the Freezing Chamber.

SECTION 4 Freezing Chamber

Tire pieces are transported from accumulator silos by belt conveyors to the air lock entrance of the freezing chamber. The pieces enter the freezing chamber at the bottom and are discharged from the top into the fracturing mill. (See section 5 folowing) Air at 1230 C from the Air Plant enters the top of the freezing chamber and discharges into a recirculation system at the bottom. The super-cooled air freezes the tire pieces in a counter-current manner creating thus an efficient thermo dynamic process. The freezing process takes approximately 30 minutes

SECTION 5 Fracturing Mill

The patented Tirex Corporation Fracturing Mill receives the frozen, glass-like rubber pieces directly from the freezing chamber exit chute. The fracturing mill is the heart of the entire system; it breaks down sections of the tires into various mesh sizes without cutting or shredding the steel or fiber strands. The frozen treads or sidewalls are disintegrated into coarse rubber powder and the steel wires and fiber strands remain intact, facilitating the separation process (See section 6 following).

SECTION 6 Separation System

The wire is removed magnetically and is conveyed to containers and is then sold. The fiber is screened off and is conveyed to containers and can also be sold. The rubber powder is screened to various mesh sizes and packaged for shipment or sent to a regrind operation in the event that customer requirements demand even finer mesh sizes or if the TCS operator needs to modify the output mesh profile to get higher proportions of finer mesh crumb.

what size is 30 mesh crumb rubber, ie is it 2mm or bigger
