Any kind of crusher is much more than just a crushing machine. They are usually based on the principle of some force and combine with other kinds of effect to reach the crushing purpose. Therefore, the applied force of crushing equipments is complicated. In most cases, we just consider the main force and take the effect of other force only as an incidentally reference.
The applied force of the crushing machinery can be divided into the crushing, split, grinding, breaking, impact, etc. Of course, it is also related to the actual situation and the mechanical properties of the crushing materials. Before the crushing process begin, we should consider the compressive strength of the materials; as with split, attention should be paid to the tensile strength of the materials; for the break, operators should focus on the bending strength of the materials; when grinding materials, we should consider its shear resistance strength. When the ore is impacted, we should consider its impact strength. After learning the working principle of various crushing machinery, we should get a general idea of the crushing force. For example, when the ore crushed between the tooth plate of the crusher, the applied force is split, the splitting strength of the ore is about 1.2 times of the tensile strength of the ore.
We should know the mechanical properties of the raw materials and the applied force situation of the crusher before the operation. It is necessary to pay attention to the applying mode of the crusher, the applied force should be consistent with the nature of the raw materials, which will have a good effect. As for the brittle rock, bending and splitting is the more favorable, since the grinding process will cause too much fine powder in the product. Materials with higher stickness, it is better to use grinding way.
With the development of domestic economy, people have tighter requirements on sand products. Henan Hongxing will help you analyze main factors that will affect the development of sand :primary crushers:http://www.hxjq-mill.com/products/jaw_crusher.html
1.Hardness of the material .
The harder the material is, the more difficult for sand market to crush. In addition, hard materials will cause more serious wear and tear on the machine.
2.Fineness of sand material
Fineness requirements, which refers to the specific size of sand materials. It depends on customers" needs for the finished products, if there is no special requirements, the general fineness of the material is based on the fixed system .
3.Composition of the materials
Before the machine starts, operators should check whether the material contains powder. As powder is easy to adhere when the crushing process begins, operators should sieve the material in advance.
4. Humidity of materials
If materials contains water, it is likely that the water will be transported during the crushing process, leading to the losses of sand materials. The solution to solve the problem is to ensure that all materials selected is necessary to strictly control the temperature of the material, if the temperature of the selected material is too large, dried or sunshine can be used to reduce the percentage of moisture in materials .
The above is a summary of factors that will affect sand development, only if we understand the nature of the problem can we be able to make our sand making machine to the limit
