 The site covers 400 acres. Most of the
 gravel is used for  cement.At Buckden}
 pits they have 1 excavator, 2 loading 
 shovels, 1 bulldozer,1 washer and 1   
 desander. When they begin to extract  
 the gravel they take the topsoil off. 
 Then the crane picks up the gravel.   
 They dig the gravel down to about 4.5 
 metres.The excavator lifts the gravel 
 to the desander which is like a sieve.
 It then falls onto the conveyor belt  
 and the conveyor belt takes the gravel
 up high.It drops the gravel and a     
 truck comes along and takes it to the 
 washer machine .There it is washed and
 graded.There is a weighbridge.When the
 lorries come along they are weighed,  
 then they load up & are weighed again.
 Each lorry carries 20 tons of gravel. 
 50 lorries leave the site daily.The   
 site will be restored eventually.
