Product Description

Double End Mechanical Seal Great Fineness Wet Grinding Ceramics Sand Mill Machine



The main introduction:


This sand mills are wet grinding machine for dispersion and grinding, and widely used in in coating and paint, pigment, pesticide and agro-chemical industry, pigment and dyestuffs, printing inks, gravure inks, food and food processing,non-metallic minerals. The main consists of chamber and disc dispersing system including the turbine separation. The series have great flow rate and super fine discharging, the finally fineness can be reach 1um for D90 and 200-300nm for D50 .The cooling efficiency is better than normal mills because the sectional double spiral water course is more beneficial to heat exchange. The grinding efficiency is higher 15-30% than traditional mill machines; the combined disperser can rapidly increase dispersing efficiency. All the materials of contact parts could be choosen from wearable steel, stainless steel, and PU and silicon carbide ceramics for meeting different requirements.



The advantages of sand/ bead mill


1. The structure is compact and stable:

The motor is placed on the upper part, the grinding chamber is placed on the lower part, and the total height of the equipment is low. Bead mills with volume over 20L are equiped with cylinder slide rail for easy maintenance.


2. Double mechanical seal:

It has 2 patented technologies, with forced coolant, sealing ring resistant to 1600 kinds of solvents, coolant is compatible with materials, no pollutants, reliable operation.


3. Discharge separation system:

Large flow, nonclogging: dynamic hollow rotor-super large area slot cylinder separator uses dynamic centrifugal force separation principle.Use of extremely small grinding beads ( 0.3 to 3 mm).No export blockage occurs under high flow conditions. Good heat dissipation, narrowest particle size distribution.


4. Disc materials and shape:

3 side discs, 4 side discs, curved discs, lumbar discs and eccentric discs, different materials can be selected, such as stainless steel, alloy steel, ceramic, hard alloy, polyurethane, etc.


5. Grinding inner chamber :

It has two patented technologies: chamber cooling and disassembly. The chamber volume is from 0.6-300L. The materials are stainless steel, alloy steel, ceramic, hard alloy, polyurethane, etc.


6. Electrical display and control:

Basic column of operation type, more integrated higher control system and PLC Allwin data acquisition hardware and software system, and more process control and process optimization system.



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.
