Rock crusher can bring the mining industry to its feet, which has helped the local clients make high profits. A new combination rock crusher and roller mill that has the capacity of crushing a four by six rock into "ultra fine powder" in one single, quick and efficient operation. They have combined two separate processes of rock crushing into a single machine.
Rock Crusher in Philippines
In Philippines, explosives or excavating are used to remove rock from the earth for crushing. Rock can also be natural, gravel or construction waste. Rock is crushed in two or three different phases: primary, secondary and tertiary crushing. The crushing process often involves one or more phases of screening to separate the different sized varieties. The first stage is a rock crusher that crushes aggregate to one quarter of an inch, that can be adjustable to larger or smaller size and the second stage is an adjustable roller mill that further reduces the grind to a fine powder.
Portable crushers or stationary crushers are used in the crushing process. An excavator or wheeled loader loads the rock to be crushed into the crusher's feed hopper. The feeder moves the rock material to the crusher.
The crusher breaks the rock into smaller grain size. The biggest crushers can crack boulders that are about one cubic meter in size. The crusher is powered by a diesel engine. From the crusher, the rock material is dropped onto the main conveyor that moves the end product upwards and then drops it into one big pile or into the feed hopper of the next crusher. Metal in the rock material moving along the main conveyor can be separated with a magnet separator, which throws the metal pieces to the side of the conveyor.
The finer portion of the rock material can be screened out already before it advances to the crusher. The screened material can be directed to the main conveyor and will thus end up in the same pile as the end product, or a secondary conveyor can direct it to a separate pile.
With some crushers, equipment attached under the main conveyor can screen and sort the end product into two or three separate piles based on the fraction size. The end product piles are removed as needed with a wheeled loader and the material can be loaded onto trucks, for instance.
