HS16 HEAVY DUTY PRIMARY SHEAR

General
An electro-hydraulically driven, heavy duty rotary shear and associated equipment for primary size reduction of a variety of scrap metals, including tyres, rubber, plastic drums, metal, wood, cable and pallets.

Designed as a free-standing machine that can be used on its own or form part of a process line.
Blade design allows edges to be sharpened many times to reduce cost.
Three part rotor that can be easily removed with minimum downtime.
Automatic reversing device which protects the machine against damage if a solid object is presented that cannot be processed.
In-feed hopper can be modified to customer’s requirements.
Proven technology over many years in successfully shredding tyres.

History
The HS16 heavy duty primary shear was built and installed in 2001 at the Midco Ltd tyre recycling facility in Edmonton, North London.
It operated successfully on shifts for over 5 years until the end of 2006 when the then owners, Credential Environmental, decided to close the operation down.
The machine was decommissioned and transported back to the supplier works where it has undergone a complete strip down and refurbishment,
replacing all of the worn parts. The line comes complete with tyre pushing system, heavy duty shear, discharge conveyors, power pack and drum grader.
Designed to produce 150mm shred, from an infeed of either whole car or truck tyres.
Similar machines have been successfully installed in the UK. And an identical line can be seen operating in the UK (see attached photo).

Question & Answers
What is the capacity?
For tyres 5 to 6 tonnes per hour. On a single shift you could process circa 7,000 tonnes of truck tyres per annum including
the down time for maintenance and circa 13,000 tonnes of car or in between as a mixture.

What is the electrical power consumption?
Power consumption is approx 50 kWh per tonne, the shredder is driven by a high torque hydraulic motor with an installed power of 160 kW.

What is the cutting principle?
The 3 piece rotor houses interchangeable triangular blades which rotate against the interchangeable fixed blades.
Rotor shear knives on shaft or knife blocks in shaft. Mono shaft cutting against fixed knife table.

What is the whole construction next to the shredder on the picture?
Complete system, shredder, hydraulic drive station, 3 conveyors, cooling system and sizing drum grader.

How big is the tyre hopper? Is this suitable for truck tyres?
Machine takes car and truck tyres including super-singles all with steel beads included. Max. dimension for tyres is 1400 mm in diameter.
The tyre hopper is big enough to take 3 or 4 super single truck tyres, loaded by a grab, the pusher system operates automatically
to push the tyres into the rotor.
