ball mill is a type of grinder used to grind materials into an extremely fine powder mainly for use in the mineral processing industry. Ball Mills can grind various ores and other materials either wet or dry, depending on requirements.
Ascend Ball Mill is a key equipment to grind the crushed materials, which is widely used in the manufacturing industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics.
Dry type ball grinding mill is to grind feldspar, glass, dolomite, quartz, silica sand etc. Using ceramic lining plate, the raw material could keep high purity. It also could be get very fine powder such as 1500 mesh together with air classifier machine.

In mid-October, 2 to 3 kg of mature seeds of Nanling pods were collected in the hilly and barren hills near Zhangzhou. The color of the ripe fruit was red or bright red. Stacking for 2 days, let the fleshy peel fully soften, then wash with clean water, remove the fleshy peel, put it in a ventilated, shade place, and put it into experiment immediately. Seed clarity was based on GB/T 3543.3-1995 Crop Seed Inspection Protocol - Clarity Analysis. Use a blast cleanness meter for processing. Calculation formula: Sample cleanliness (%) = Sample weight with removal of inclusions / Sample weight × 100%. Seed clarity is one of the important indicators of seed sowing quality. The higher the degree of clarity, the better the seed quality.
Through the test of the net seed treated by the blown type tester, the plant seeds will only germinate within a certain temperature range, because the temperature affects the activity of the internal enzymes of the seeds, thus affecting the operation of the internal substances of the seeds and the water absorption and gas of the seeds. exchange. The biological characteristics of the seed germination of Nanling Luhua are mainly reflected in the following aspects: The seedlings of Luanhua Nanling grow from August to October, and the ripening period is earlier. When the fruit is mature, the fruit is reddish; The main germination factor, as long as the water is sufficient, the temperature of 26 °C can promote seed germination. Before the seedlings of Nanling lindens germinate, it is not necessary to go through the winter dormancy or low temperature process. This indicates that the seeds of Nanling annatto seeds may not contain the substances that inhibit germination or the content is extremely low. The mechanism needs to be further studied.
The Application of Air Purity Tester in the Study of Nanling Amaranth
Nanling Azalea has many distributions in subtropical regions of China. It is an excellent shrub plant for soil and water loss and vegetation recovery. It has the advantages of drought resistance, barrenness and strong sprouting, and its bark fiber is developed. It is printing paper and copper plate. The main raw material for high-grade pulp such as paper. In order to provide reference for the application of Nanling Amaranthus to the recovery of vegetation in more soil erosion areas and the cultivation of pulp forest, the biological characteristics of the seedlings of Nanling Amaranth were studied. In the process of seed research, the blast purity meter plays a very important role in the cleanliness of seeds.
