Introduction 
Pin type horizontal sand mill is a nano grade wet grinding machine. It is updated from disc type, which has wider range of viscosity and higher precision. 
It is an ideal choice for modern coatings, inks, pigments, etc. 

More information
Constructing materials
Outside cylinder: Stainless steel 304
Inisde chamber: High wear-resistant alloy steel (SKD11), hardness>60hrc
Pins: YG6 (Tungsten 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
Cooling level control: by float sensor
Cooling water interation: by cooling water pressure sensor

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 1.0-1.4mm 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.
