Nature is a very wonderful world. It provides a rich source of resources for human survival. But it also brings factors that can't be brought to humanity. Some mineral resources are harmful. The mineral resources of nature can be divided into four categories: 1. Minerals are non-toxic or even essential; 2. Minerals are strongly toxic; 3. Minerals contain toxic elements but are generally non-toxic; 4. Minerals are radioactive minerals.
Texturing Machine is applied to terylene,nylon and the yarn production and processing that need heat drafting,forming and air-texturing.
Digital hot roller and precise temperature control of shaping box ensure the quality of yarn production.Adoption of high-performance motor yarn guide system realizes the intelligent forming and high linear velocity winding.Water spray cooling function ensures the yarn stability while silk yielding from texturing nozzle.Using brushless motor for driving,the machine can save energy more than two times.Intelligent synchronous driving promises the consistency between the roller wheel and winding and the stable and reliable production.

1. Minerals are non-toxic and even essential. Minerals are non-toxic or even essential, but they can cause fatal damage under certain special conditions, including: potassium salt, diamond , asbestos and quartz .
Second, with a strong mineral itself toxic mineral itself has a strong toxicity, comprising: a red thallium ore, witherite, vitriol, arsenopyrite, orpiment, realgar, Chinese arsenic, arsine, cinnabar, galena, carnallite like.
Third, minerals, containing toxic elements but generally non-toxic
Minerals, but contain toxic elements themselves are generally non-toxic and may cause injury mainly in the smelting and use, including sphalerite, beryl, chrome iron ore, barite, fluorite, natural gold.
Fourth, minerals are radioactive minerals
For example: mineral resources such as lead.
