What kind of sand can be used as foundry sand?

The molding sand suitable for casting that is widely distributed in nature is silica sand, also known as quartz sand. The main mineral composition is quartz, and the main chemical composition is SiO2.

Natural silica sand: Due to its different chemical composition and particle size composition, it is used as molding sand and core sand for non-ferrous alloy castings, iron castings and small and medium-sized steel castings.

Selected natural silica sand: used for various steel casting molding sand and core sand using organic matter as binder.

Artificial silica sand: molding sand and core sand used for precision casting, furnace lining or steel castings.

Maintenance and storage method of vibrating screen motor and common troubleshooting

The service life of the vibration motor determines the operating life of the entire screen. Therefore, in the normal production, we must always pay attention to whether the working state of the vibrating screen equipment is normal, whether the vibrating motor is in good working condition, timely check and solve some small abnormalities and faults, and do a good job of cleaning and maintenance, because this can greatly increase the vibration screening. Machine and vibration motor life. dewatering screens supplier Maintenance storage precautions during vibrating screen motor operation The equipment can not be completely dust-free, but also has a harsh environment and dusty conditions. The vibration motor is airless and heat-cooled. It relies on natural cooling, so it must be specially maintained. The following is the maintenance content. 1. It is necessary to pay attention to whether the vibration is abnormal during the use process; 2. Always check if the bolts used in the m

300t per hr chalcopyrite washing equipment

Chalcopyrite is a copper-iron sulfide mineral. It often contains trace amounts of gold and silver. Crystals are relatively rare and are tetrahedral-shaped, mostly irregular granular and dense massive aggregates, as well as kidney-shaped and grape-shaped aggregates. Copper yellow, often dark yellow or mottled. The streaks are black with a greenish tint. Chalcopyrite is a relatively common copper mineral, which can be formed in different environments, but it is mainly the product of hydrothermal action and contact metasomatism, and it can often form deposits of a certain scale. The origin is all over the world. In industry, it is the main raw material for copper smelting. In the field of gemology, it is rarely used alone, occasionally as a substitute for pyrite. In addition, it often participates in the composition of some colored stones, inkstones and jade. The high-efficiency spiral chalcopyrite washing machine is mainly used in the washing, grading, impurity removal, and the washing o
