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.

The abrasive wear failure of the blades of the spiral sand washer is a common phenomenon in the sand washing equipment. The reason for this phenomenon is that the blades have been rubbed by materials for a long time and have been strongly impacted during the cleaning process, especially some larger particle sizes. The sand washing machine has a fast wear speed, and the wear is serious, and the blade surface will affect the normal production requirements of the sand washing machine. There are three main reasons for the failure of the spiral sand washer blade: 1. The external force on the sand washing equipment or the temperature change caused by the material may increase the internal stress of the spiral sand washing machine blade, resulting in carbide cracking. 2. When the spiral sand washing machine adopts the heat treatment method, cracks may occur on the surface of the casting, and continuous cracking may cause the blade to break and fail. 3. If the blade part of the spiral sand wa...

method to  slove the blockage of the screw feeder 1. Reasonably select the technical parameters of the screw feeder, such as the speed of the slow screw conveyor should not be too large. 2. Strictly implement the operating procedures to achieve no-load start and no-load parking; ensure that the feeding is evenly continuous. 3. Increase the discharge port or lengthen the end of the trough to deal with the problem of poor discharge or too late to discharge. At the same time, a small section of counter-rotating vanes can also be installed at the end of the material trough at the discharge port to prevent the material from being blocked at the end. 4. Make necessary arrangements for the materials entering the screw feeder to prevent large debris or fibrous impurities from entering the machine and causing blockage. 5. Reduce the lateral size of the central suspension bearing as much as possible to reduce the possibility of material blocking when the material passes through the central b...

  1. Ordinary quartz sand: The surface of ordinary quartz sand seems to have a layer of yellow skin, and some have large particles and strong fire resistance. It is a kind of quartz sand processed by the manufacturer after using natural quartz ore in the production process, such as washing and drying. No impurities can be seen in the quartz sand through the second water treatment filtration. It is the best choice for chemical water treatment. It can block the sundries suspended in the water and maintain the quality and beauty of the water. 2. Refined quartz sand: Refined quartz sand is a mineral made by the manufacturer after carefully selected quartz stone. According to different requirements of users, the range used is also different. But generally the main use of refined quartz sand is in glass products, because refined quartz sand is refractory and precision casting, especially suitable for fireproof glass materials.
