To judge the quality of river pebble finished sand produced by large-scale machine-made sand and gravel production lines, the following aspects can be used: whether the sand is uniform and non-sticky; whether the sand is clean and free of debris; whether the sand meets national standards; if all three standards are met, then it is a relatively good quality sand and gravel that can meet the production requirements of various industries.

1. Whether the sand is uniform and non-sticky

In the fields of construction and metallurgy, sand and gravel must meet the standards of uniformity, fineness and non-stickiness to be favored by the industry. To this end, the key to the sand production line is to be equipped with an efficient river pebble sand making machine, which integrates a dual crushing mechanism and a deep cavity design to ensure that large pieces of ore are fully crushed and the finished product has a uniform particle size. Its adjustable discharge port accurately controls the fineness of the sand particles, surpassing the flexibility of natural sand. Add a circular vibrating screen link to effectively screen out sticky impurities, and finally produce pure, uniform and non-sticky sand, which perfectly meets the high standards of the industry.

2. Is the sand clean and free of debris?

The river pebble sand production line integrates an efficient sand washer to ensure excellent sand washing purity. After the sand and gravel enter the sand washer, they undergo all-round flipping and cleaning, effectively removing dust and impurities and improving the purity of the product. The equipment allows flexible adjustment of the cleaning time and frequency to meet personalized needs and fully demonstrates humanized design. At the same time, the production line is supplemented by a screen wind device to further enhance the cleaning effect, ensure that the output sand is clean and flawless, without any debris, and fully guarantee product quality.

3. Does the sand meet national standards?

In view of the fact that the country has restricted the mining of natural sand and has instead vigorously advocated and strictly supervised artificial sand making, quality assessment is particularly critical for the products of the river pebble sand making machine production line. In order to ensure the high quality of sand, it must be fully tested, focusing on core indicators such as density and hardness to ensure that each item meets the established national standards. Only sand that meets the standards can guarantee reliable quality; otherwise, it should be discarded to avoid affecting the quality and safety of the project. Therefore, strict testing is a necessary measure to improve the quality of artificial sand making and ensure market application.
