Water content (a) dry-milling <br> <br> pulverizing material pulverized at 4% or less are referred to as dry pulverization. Its characteristics are:
(1) The treated materials and their products are dry.
(2) When smashing, dust collection equipment should be installed to avoid dust flying.
(3) The efficiency of grinding in fine grinding is low.
(4) When the water content exceeds the quantitative amount, the particles are bonded and the pulverization efficiency is lowered.
(5) It is more difficult to remove fine particles from the pulverizer (usually used for air blow-up)
(B) wet grinding the crushed material <br> <br> water content of 50% or more, and the fluidity of the wet pulverization is called pulverization. Its characteristics are:
(1) Raw materials that are wet can be processed directly without drying.
(2) The material after pulverization is convenient to be removed, the pulverization efficiency is high, and the transportation is convenient.
(3) No dust is generated in the operation site.
(4) Particle grading is relatively simple.
(5) Substances that are prohibited from being soaked or soluble in water cannot be used in this manner.
(6) Drying equipment is required for the crushed material.
The above two smashing methods each have advantages and disadvantages. Generally dry type is often used for material crushing, and wet type is often used for material grinding. The carbon and electric carbon industries generally use dry pulverization.

Freon Solvent Recovery Machine
Freon Solvent Recovery Machine is a special equipment made for organic solvent recycling. It has a tilting-type air-cooled condensing system, quality build, and is manufactured according to Chinese explosion-proof directive (CNEX) and European directive (ATEX). The organic solvents are recycled through distillation and cooling.
