Mineral Processing Equipment in Processing Plant

Oct. 25, 2012 - PRLog -- Breaking is the process that bulk material comes into smaller particle size under the action of mechanical force. Breaking is an important part of mineral processing. Breaking can be divided into four stages: crushing, grinding, fine grinding, and ultra-fine grinding. Breaking process is energy-intensive operations, and the basic principle of breaking process is “more crushing and less grinding".

Mineral Breaking Process

1. One section breaking process. One breaking process is generally used to provide suitable feeding for grinding mill, often constitute a system with grinding mill. The process is simple, with less equipment and small footprint. 2. Two sections breaking processes. It is mostly adopted by small-scale plant. 3. Three section breaking processes. The basic forms of the process are open circuit and closed circuit. 4. Washing process. When the clay content in the feeding material is more than 5% to 10%, or water content greater than 5% to 8%, should to add washing operation in the breaking process.

Mineral Breaking Equipment

There are so many kinds of breaking equipments in industrial application. According to the working principle and structure, the breaking equipments can be divided into: Jaw crusher, Cone crusher, Roller crusher, Vertical impact crusher, grinding machine and so on.

1、Jaw crusher

Jaw crusher is working by the moving jaw plate periodically press to the fixed jaw plate, breaking the material sandwiched between two plates. According to the movement tracks, moving jaw plate can be divided into simple swing jaw crusher and complex swing jaw crusher. Jaw crusher is also called as "tiger mouth" , is one of crushing machines have long history, is still the most effective equipment to crush hard materials.

2、Cone crusher Cone crusher is working by conical surface move rotary to closed to the fixed cone periodically, so that the material sandwiched between two conical surface can be extruded and bended, and then broken. ）

3、Roller cone crusher The working parts of roll crusher are the relative slewing two rollers. Roller surface can take the teeth, called tooth roll crusher. Its main function is split breaking, combine with squeeze breaking. According to the roller number, roller crusher can be divided into single roller crusher, double rollers crusher and multi-rollers crusher.

4、Vertical impact crusher Hammer crusher and impact crusher are all vertical impact crusher. There is a high-speed rotor in the crusher, fitted with the hammer, when the material come into the crusher, will be crushed by high-speed rotor or obtain energy from the high-speed rotor.

5、Grinding machine Grinding machine, also called as grinding equipment, is a machine used for grinding, which is using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel’s surface cuts a small chip from the work-piece via shear deformation.
