How to build a sand and gravel aggregate production line

High-quality aggregates (coarse aggregates and fine aggregates, fine aggregates are sand): First, the shape of the particles should be good, and the senses should be good; second, the gradation should be reasonable. Especially for machine-made sand, high-quality machine-made sand products must not only meet the sand requirements of commercial concrete, but also meet the requirements of higher standards for ready-mixed mortar sand (ready-mixed mortar is an inevitable requirement in the future. On-site stirring will be phased out over several years). Reasonable continuous grading can meet the needs of high-quality concrete. Both are indispensable.

The fifth condition for the success of the sand and gravel aggregate production line is that the aggregate product of the production line must meet the requirements of soil content. High-quality concrete has higher and higher requirements for soil content. The seemingly simple problem may be the reason for the failure of the project. There is more rain in the south and water shortage in the north. Some mines contain less soil on the surface, some contain more soil, and some There are top layers of soil, and so on. Different processes need to be adopted in different situations, otherwise it will cause the failure of the project or increase the huge cost of post-transformation.

The ore characteristics of the mine determine many quality characteristics of the finished sand and gravel products in the future, which cannot be changed by changing the process flow of the production line, such as the strength index and the content of the needle-like finished products, which are also largely related to the characteristics of the ore. Alkali active substance content, mud content, etc.

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
