Engine Crushers And The Scrap Car Industry

Engine crushers are an essential piece of machinery in any scrap metal dealer’s yard.  Recycling engine parts are lucrative for the scrap metal dealer and the car industry as a whole. It is much cheaper to reuse the metals found in old engines than it is to produce the metals from scratch.  Many new cars use a small percentage of recycled materials in their construction.

The scrap car industry is increasing due to the increase in the number of vehicles on the road and people purchasing new cars.  Approximately 1.7 million cars are scrapped in the UK every year with 95 % of the car being recycled. The largest car shredder in the world resides in Wales and is able to shred 450 cars an hour.  (Source: Scrapcarnetwork).

Scrapping cars is a complex procedure due to the wide range of materials involved and hazardous fluids. Sorting the materials manually is time-consuming and uneconomical so using engine crushers makes the job much easier.  The machine sorts ferrous and nonferrous metals including aluminium.

What Is A Car Engine Made From?

A car engine consists of the following components; engine block, crankshaft and connecting rod.  The engine block is the main structure of the entire engine and makes up for 25% of its total weight.  It is made of grey cast iron alloys, aluminium alloys and compacted graphite cast iron. Modern engine blocks are mainly aluminium alloy because traditional iron alloy engine blocks were getting to heavy and weigh the car down.  Also known as a cylinder block the engine block contains cylinders, passages for coolant, exhaust and allows gases to pass over the engine.

The crankshaft is housed inside the engine block and is made with iron steel alloy with a high carbon content.  It is positioned at the bottom of the engine and converts the up and down motion of the piston into a rotary motion. The crankshaft is also connected to a flywheel, clutch, torque converter, belt pulley and the main shaft of the transmission.

Connecting rods are made up of either steel, aluminium, titanium, iron and other metals. It joins the piston to the crankshaft.  (Source:Mohit Sarvaiya).

How Do Engine Crushers Work?

Engine crushers break engines and gearboxes into small particles.  This makes it easier to sort aluminium from the ferrous and other and other metallic components. The operation can either be manual or automatic.

There are two sizes of engine crusher available from challenger large and standard.  They both work in the same way by reducing engines into small particles. An automatic or manual version is available with extras including; petrol engine drive, hoppers, support frames, hydraulic oil coolers, adjustable finished particle device, warning alarms, feed and discharge conveyors.  Here is an engine crusher in action.
