Due to the pebble with high hardness and great silica content, the wearing parts are abraded heavily is the biggest problem in the pebble crushing process. So in the project with pebble as raw material, Baichy will priorly recommend to use laminating equipment and multiple stage crushing solution considering of customer condition. Jaw crusher and cone crusher are the main crushing machine in the multiple-stage crushing equipment. They could reduce the cost of wearing parts uttermost and also reduce the rework after screening, so to reach the purpose of increasing the production capacity finally. If the customer doesn’t care too much about the size and shape of final products, the two-stage jaw crushing solution is also suggested. This solution is in low investment and maintainence easily. However, the weakness is poor shape and low competitiveness in the market.
Granite is the rock most often quarried as a “dimension stone”-a natural rock material that has been cut into blocks or slabs of specific length, width and thickness. Granite is hard enough to resist most abrasion, stone enough to bear significant weight, inert enough to resist weathering and it accepts a brilliant polish. Granite is also used as a crushed stone or aggregate. In this form it is used as a base material at construction sites, as an aggregate in road construction, railroad ballast, foundations and anywhere that a crushed stone is useful as fill.
Raw material:Granite
Moh'shardness: 7~8
Feeding size:30-50cm stone boulder
Capacity:200t/h.
Discharging size: Output size: 4.75mm only one kind of product based on IS standards for M sand .
Application: construction concrete aggregates

Equipment List:

This kind of design successfully receive the compliment from the high standard concrete aggregates supplier, Two stages of jaw crusher, two groups of fine jaw crushers and screens and two groups of psi sand maker formed two parallel production lines.The budget is almost same with cone crusher and psi sand maker, but the capacity is a little larger than adopt single one cone crusher. And it is more convenient for Maine, longer service because of two lines. Even though nth is wrong with an equipment or one of the lines need to shut down for adjust,  the whole plant can operate normally.
