As high-standard screening equipment, the screening machine can also be used for the screening and grading of raw materials and bean husks in large oil plants, as well as for the screening and grading of large-granular urea in chemical industry, powdery materials or pellet feeds in feed factories. It can also be used for the initial cleaning of raw materials in feed mills and the classification of intermediate products after secondary crushing in large and medium-sized feed mills. In addition, it can also be widely used in food, heavy alkali, large particle urea, small particle urea, ceramsite, zirconia, reduced iron and titanium powder, barite, food and spices, chemical industry, plastics, mining, rubber, wood and Screening and grading of raw materials and finished products in various industries such as plywood, medicine, sugar, mining, and paper. With the development of the market circular economy, screening and screening in the waste plastics industry are increasing day by day, and ...

 Let’s check its ingredients first! Among the mineral particles that make up granite, more than 90% are feldspar and quartz, among which feldspar is the most. Feldspar is often white, gray, and flesh red, and quartz is mostly colorless or off-white, which constitute the basic tone of granite. Both feldspar and quartz are hard minerals that are difficult to scratch with a steel knife. As for the dark specks in the granite, it’s mainly biotite, but also some other minerals. Although biotite is relatively soft, its ability to resist pressure is not weak. At the same time, their weight in granite is very small, often less than 10%. This is the material conditions under which granite is particularly strong. Therefore, sand with high compressive strength can be obtained by using granite sand. source: https://www.lzzgmachine.com/solutions/why-does-granite-machine-made-sand-have-high-strength.html

 1. When choosing, you should pay attention to the following two points : (1) If the power of the vibration motor is too small. The phenomenon of “small horse-drawn cart” will appear, causing the vibration motor to be overloaded for a long time. Its insulation is damaged due to heat, and even the vibration motor is burned. (2) If the power of the vibration motor is selected too large, the phenomenon of “big horse-drawn trolley” will appear, the output mechanical power cannot be fully utilized, and the power factor and efficiency are not high, which is not only unfavorable to users and the power grid, but also cause power waste.
