There are several characteristics to consider before buying a crusher:
1.The abrasiveness and hardness factor
First of all, you should know what are the materials are going to crushed. It is very necessary to learn their abrasiveness and hardness. You must evaluate the compressive strength or maximum force that the material can withstand before breaking.
Feeding size: 125-1020mm
Application: widely used for medium-sized crushing of ore and bulk materials in mining, metallurgy, construction, road, railway, water and chemical industries
Processed Materials: Granite, marble, basalt, limestone, quartz, river pebbles, iron ore, copper ore, etc.
2.The dimensions. You will need to consider the maximum dimensions you need to enter into the machine (length, width and thickness).
3.Granulometric requirement. It is necessary to define the desired result i.e. the size you need after crushed, the shape of final product.
4.The capacity or throughput. You should determine the processing capacity which can afford your needs of aggregate for use. It is usually measured in tons in an hour.
Then you can choose which types of crusher you need.
Feeding size: 100-350 mm
Productivity: 3-350 t/h
Application: This machine is widely used in mining, building materials, chemical industry, metallurgy and so on. It is suitable for primary and secondary crushing of all kinds of minerals and rocks with compressive strength less than 320 mpa.
