Pigment and Ink grinding machine disc type

Introduction
Disc type horizontal bead mill is one of the earliest wet grinding machines with good performance and mature structure. There are various dispersing discs mounted on the main shaft. Grinding beads collides and rubs intensely under the force of discs, which grinds and disperses materials that go through the grinding chamber effectively. 

More information
Constructing materials
Outside cylinder: Stainless steel 304
Inisde chamber: High wear-resistant alloy steel
Discs: high wear-resistant alloy steel

Mechanical Seal
German Bergman double-end mechanical seal
Dynamic and static ring: made of steel-bonded tungsten carbide
Housing:SUS304
Cooling: closed circulation, cooled by the cooling water through pipes 
Protection: Monitored by magnetic level gauge

Electrical part
With PLC touch screen, Siemens brand (exproof optional)
Instruments: pressure gauge and temperature gauge

Other parts
Bearing: Japan NSK 
Transfer pump: IngersollRand
Discharge: materials are discharged by dynamic and static rings, avoid blocking
Grinding beads:pure zirconium beads, size among 1.5-2.0mm based on materials partical size. 

Protection System
When there is no cooling water or the water pressure is not as required, the mill can not be started. 
When the material feeding pressure and temperature is above set value, the mill will be stopped automatically. 
When the cooling oil level is low or none, the mill won't be able to start, or it will stop automatically to protect the mechanical seal. 
Delay shutdown: after production, the feeding pump turns off first, and the engine will be shut off within a set time which enables the left materials discharged fully from the chamber and makes it easier to clean or change colors.
