Four Stages to The Process of Crushing

Crushing process and equipment plays an important role in crushing industry, which also is the greatest concern problem per customer pay a lot attention to. Next, let us to share the related knowledge together.
Crushing(jaw crusher) is an important link in the process of machining ore or stone, and crushing is also this procedure that huge materials, for instance, big ore or rock, change little and little under the action of the force from machinery.
The process of crushing belongs to energy-consuming homework, according to the granularity that was discharged by discharging mouth is big or small, crushing can be divided into four stages: crushing, grinding, fine grinding, superfine grinding, etc.
The flowsheet ofcrushing as followings:
1. The first crushing flowsheetthe first stage of crushing generally used for supplying appropriate materials for autogenously grinding mill, and which always constitute a system together with autogenously grinding mill. The simple crushing flowsheet, less equipment, the workshop covers less area, which are the features of crushing flowsheet .
2. The secondary crushing flowsheet the crushing flowsheet widely used in small factory.
3. The tertiary crushing flowsheet the primary type of crushing flowsheet have two kinds, namely tertiary opening flow and tertiary closing flow. Here, explain about opening flow and closing flow.
The opening flow in crushing: during the crushing process, after material, such as ore, stone, rock, etc, was crushed, those have crushed materials will not return into crushing equipment.
T
he closing flow in crushing:
During the crushing process, after the products that were crushed were screened, those screened products will return crushing equipment again for further crushing.
4. Ore washing of crushing processif the content of silt in feeding exceeds 5%-10% and water is 5%-8%, and then ore washing homework should take into account.
The development of the technology for beneficiation craft and beneficiation equipment is almost synchronous, the technology level of crushing is not only the best present of the craft standard, but also of which the state of technology used in production has a big and direct influence on the production process, the quality and quantity of products, also including compositional economic result.
As the professional manufacturer of complete sets of mining machinery, such as Sand washer supplier，Cement production line, Henan Hongxing is always doing the best in products and service.
