Question
On what basis are materials to be crushed evaluated apart from size?
Answers
The choice of the crusher machine to be employed to crush the materials depends on the following properties apart from the size of it:

Hardness: The hardness affects the power consumption and the wearing of the machine. With hard materials it is necessary to use a low speed machine along with pressure lubrication.
Structure: Normal granular materials can be crushed by using compression and impact methods. On the other hand for fiber like materials compression and impact methods don't work instead a tearing action is required.
Moisture content: The moisture content in the materials can greatly affect the choice of machines. In case of excess moisture the materials flow gets hindered and it is essential to prevent them from caking together and form balls.
Crushing Strength: The amount of power that is required to crush a material can be derived directly from the crushing strength of the material.
Friability: This property indicates the tendency of a material to fracture.
Stickiness: As the name suggests this property is used to evaluate how sticky a material is as a very high sticky material can clog the machinery.   Your Comment

He found that he could arrange them all in the form of a triangle whose area was just as many square inches as there were matches. He then used up six of the matches, and found that with the remainder he could again construct another triangle whose area was just as many square inches as there were matches. And using another six matches he could again do precisely the same. How many matches were there in the box originally? Note that the match-box can hold maximum of 50 matches.
