Product Description

300Kg Sand Mill Machine Low Temperature 20L Wet Bead Milling


The mian feactures:


1. Different materials for meeting dirffent needs :

Adopted high abrasive-resisting materials:silicon carbide ceramics,like hard alloy, 9Cr18Mo alloy steel, SUS 304 stainless steel, to guarantee strengthen working life of bead mill machine. Meanwhile we suggest the suitable grinding beads to match with the inner chamber materials.

2. Decrease the temperature:

Applied self-owned double spiral cooling technology to enhance the space of heat rejection, with superior material with good thermal conductivity and lower the temperature before coollant come in pipe. also temperature is lower if choose the inner chamber of Silicon carbide ceramics.


3.  Strenghten the fineness:

The  different fineness after grindinig can be reached for your different demands,  the smallest grinding media of 0.1mm with 200-300nm.


4. High efficiency low energy:

High efficiency with enegry saving, have indepently grinding and dispersing technology, nomarlly the efficiency is higher 10-30% than traditional machines. also it's more better if choose the temperature is better.


5. Reduce the workforce with  indicator light

 One worker could easily operate and manage 5-10 sets mill machines if mills add the indicator light,  decrease the cost of humen. the mill machines will add more if need central control system. It's will be automation and intelligence and saving more labor cost. 


The working principle:

1. The materials are pumped to pipe to feed the solid-liquid mixture material that has been pre-dispersed and wetted by the mixer into the chamber

2. The material and the grinding medium in the chamber are stirred by the high-speed rotating disperser,

3. The solid particles in the material and the grinding medium produce stronger collision, friction, and shearing effects with each other to achieve the purpose of accelerating the grinding of fine particles and dispersing .

4. The material passes through a dynamic separator to separate the grinding medium and flows out of the discharging pipe.

❶ How to choose the appropriate sand mill machine?
According to your raw material of grinding, the input finness and output finness you need, production capacity per houre or per day, other special requirements like temperature , color, explosion performance,etc. Then we offer the most appropriate instrustions of wet grinding sand mill.


❷ How to ensure the grinding machine can operate regularly after taking delivery?


Firstly, we offer running test before shipping. Secondly, operation instrustion will be delivered with the equipment, you need to read the instructions first. Thirdly, we can offer vedio instructions to help installment, maintance. Finally, if all methods have tried and the machine could not operate regularrly, we could arrange enginner to solve the problem.


❸  Are you the supplier and manufacturer of wet grinding sand/bead mill, rather than a trader or trading company?

ALLWIN is the professional manufacturer of grinding and dispersing machines , located in TONGXING industrial zone, Beibei, Caijiagang Town, Chongqing, China. ALLWIN has won famous reputation in China and old friendly customers, llike AkzoNobel, Kansai Paint, Musashi Paint, Beacon Coatings,etc. Warmly welcome all customer to visit us.
