High Speed High Viscosity Pigment Or Ink Lab Three Roller Mill With Zirconia Ceramic Roller And Stainless Steel
Frame
Summary:
The three-roller mill is mainly used for various kinds of paste
such as paint, ink, pigment, plastic, food, etc.This machine
achieves the grinding effect through the surface of the three
rollers arranged horizontally by the machine and the friction of
different speeds.Generally speaking, the grinding material can meet
the requirements by grinding it twice.But the difficult material
must be ground many times in order to meet the requirements.
The final processing fineness can reach about 3-18μ m (measured by
fineness scraper), but it is not suitable to grind the raw material
with acid-base composition or enough to cause the roller corrosion.

Structure of equipment (device)
1. Machine section
The body adopts castings, which are composed of machine seat and
upper cover plate. The left and right sides of the body are
equipped with one of each side of the double row centered roller
bearing in horizontal direction, and are connected with the upper
cover plate. The middle roller bearing seat is bolted with the
adjusting screw and the spring on the cover plate to make the front
and back movement. The right end of the bearing seat is used to
support the slow, medium and fast three rollers. The right end of
the roller shaft has a cooling water pipe and water tank, and the
left end gear.
2. Transmission section:
The lower part of the machine seat is equipped with a motor, which
is driven by triangular tape to pass into the fast roller, which is
driven to the middle roller by the gear, and the middle roller to
the slow roller.
3. Roller:
The roller is divided into fast, medium and slow one, all made of
cold hard alloy cast iron, the two ends are pressed into the high
quality steel shaft head which has been heat treated, the left
shaft head is equipped with transmission gear, and the middle
through hole of the right shaft head is used as the channel hole
for cooling the roller when working. The cold hard layer of the
roller is not less than 15mm, its hardness is not less than
hardness 70, and the surface is ground by precision.
4. Feeding apparatus
The feeding device is composed of copper knife and copper knife
support, which is installed at the two ends between the slow roller
and the middle roller, the copper knife arc is close to the surface
of the slow and middle roller, and the material is not flowing, the
copper knife support is fixed on the body with bolts, which is
convenient to adjust the edge distance and disassemble and clean,
and the copper knife should be adjusted frequently to facilitate
the surface of the roller.
5. Cooling equipment
In order to eliminate the roller work properly, the heat expansion
caused by the friction affects the flat contact surface of the
roller, the cooling water pipe is installed at the right shaft head
of the roller, and the rubber pipe is installed at the water pipe
joint. After heat exchange through the inner wall of the roller,
the original hole returns to the water tank and flows into the
sewer.
6. Discharge device
The discharging plate for discharging is mounted on the body's
discharging plate support, the discharging plate is equipped with a
blade, and the blade is close to the surface of the fast roller
through the adjusting screw of the discharge plate, and the
position of the knife edge should be higher than that of the center
of the roller, so as to facilitate the smooth scraping of the
material attached to the surface of the fast roller after grinding.
4. Pressure regulator
Rotate the hand wheel, through the action of the screw and spring,
prompt the fast and slow roller to move along the guide rail before
and after, to adjust the grinding fineness of the slurry.
