Product Details

Screening analysis is one of analysis method to determine the granularity of the product composition of gravel. With screening analysis, we can know the particle size characteristics of gravel. crusher In this way we can determine the particle size characteristics of the raw materials of crushing and screening. Screening analysis is useful for us to choose the right crushing and screening equipment or production process.

Generally,screening analysis carried out in the standard sieve. Standard sieve is constituted by the different sieve pore which arrange in rank ordering of standard sieve. The size of the sieve pore gradually decreases from top to bottomcrusher. The sieve pore of standard sieve is square and the screen surface is woven screen ordinary. When the sieve pores is large, we can use punched screens.

When we do the screening analysis, put the sample on the top of screen surface which is weighed, and than screening them on the vibrator, and this process need ten to thirty minutes. When the screening analysis over, weighing the materials on each screen surface. With the total weight of the sample divided by the weight of each grain size materials, then we get the ratio of materials for each. The materials keep on the screen surface we call them sieve products, the ratio between sieve products and total weight, we call it screen residuecrusher.

Accordance with the result screening analysis, we can draw the characteristic curve of the particle size. Characteristic curve of the particle size show the relationship between the productivity and different ore granularity.

As for the products,in the crusher areas,we company Henan Hongxing Machinery Co., Ltd have more than 20 years' experience, proficient at crushing machine's researching and production.All the staff are improving the study ability of whole team with full passion, fresh vitality, and diligence.
