200L Double Mechanical Bead Grinder


200L Double Mechanical wet bead milling

Product Description

Static Large Flow Discharging Double Mechanical Seal 200L Water Based Bead Grinder



The mian feactures:


1. Extend service life :

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.


2. Decrease the temperature:

Applied self-owned double spiral cooling technology to enhance the heat rejection, with superior material with good thermal conductivity.


3. Strenghten the fineness:

Choosen smaller grinding medium to 0.3mm and finer material to chamber, discharged from more difficult seperation devices.


4.Enhance the efficiency:

According to effectively control more factors, such as grinding bead materials. size. material viscosity, chamber vulume, motor power, cooling,etc,which can effect efficiency to strengthen efficiency.


5. Lessen the personnels:

As our horizontal bead mills designed more humanized to operate the machine, a worker can easily operate 3-4 machines, to decrease the cost of humen.


6. Improve the safety:

Equiped with safety-alarming system, to warn if it operates incorrectly.




The working principle:


The working principle is to use the material input pump to feed the solid-liquid mixture material that has been pre-dispersed and wetted by the mixer into the chamber, then the material and the grinding medium in the chamber are stirred by the high-speed rotating disperser, so that the solid particles in the material and the grinding media produce stronger collision, friction, and shearing effects with each other to achieve the purpose of accelerating the grinding of fine particles and dispersing .After grinding and dispersing, the material passes through a dynamic separator to separate the grinding medium and flows out of the discharging pipe.

How to choose the appropriate sand mill?

Please tell us the 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.

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( this may need additional fees).
