Selections of types of cemented carbide of mining inserts

the right selection of cemented carbide grade is one of the most important factors that guarantee the effective application of cemented carbide.Attention should be paid to the following when the selection of the grades is done:

a. The properties of the rock formations,such as hardness,frictional characteristics,and their configuration,such as compactness,fisssures,joints,caverns,etc.The basic principle is:the harder the formation of rocks to be drilled,the much toughter the mining inserts should be.They,however,should not be too soft,and that is so say their wear resistance should not be too low,since it will increase the consumption of cemented carbide and reduce the efficiency in the drilling as well;Cross drill bits should be used if the rock formations are full of fissures without regards to the hardness of the rick formations and what types of drilling machines used.

b.The types of rock drilling machines,light or heavy types,etc.

c.Method of fragmenting the rocks formations(cutting,shearing,crushing,impacting,etc)

d.Capacity of the equipment(e.g.low or high air pressure.etc);

Grades,properties and recommended applications of conventional cemmented carbide for mining inserts.

The other matters to pay attention to

Collision of the working edges of the drill bits with metals should be avoided during transportation and in operations.

When the bits are in operation,there should be no wanton knocking at the drill body, When the drill bits are to be replaced,an apparatus should be used for dismantling the bits,If a hammer is used to knock the drill body to dismantle the bits,it will damage the drill body resulting in the premature in the premature rejection og the bits.
