With the increasing demand for materials in various industries, the requirements for particles are becoming finer and finer. Although existing sand mill manufacturers have optimized their product design, manufacturing, and processes, the existing horizontal sand mills inevitably face five major challenges.
To solve these five major problems, we have developed a new design concept and manufactured the LSM series vertical inorganic sealed mesh free sand grinder.

1. Separate NetEase blockage;
2. Mechanical seals are prone to leakage and damage;
3. Difficult to achieve ultrafine bead grinding;
4. Uneven distribution of product particles;
5. The grinding efficiency is not high enough.


1. Non sieve centrifugal separation;
2. The problem of inorganic seal leakage and damage;
3. Ultra fine grinding medium;
4. Graded separation and grinding function;
5. High grinding efficiency.
