Description

MZH- Three-Roller grinding mill

Use and performance

Three roller grinding machine is mainly used for all kinds of paint, printing ink, pigment, plastics, food and other paste slurry, but not grinding with acid-base components or sufficient to cause corrosion of roll of raw materials, mainly for paints, inks and other high viscosity material grinding and dispersion of the main equipment.

The machine machine in the horizontal direction through the arrangement of the three roller surface are jiga and different speed of friction to grinding, grinding materials as long as the general grinding quadratic can meet the requirements, difficult to research the material must be grinding times, in order to meet the requirements, fineness of finishing is generally up to 3-18 µ m a.s.l. (with the fineness of grind determination).

The main technical parameterswhich model do you select?

III. Working principle

Work fast and slow and adjusted to proper position, start the machine, then will be added to the slurry of abrasive in between the roller and the slow roll copper knife, slurry after, the slow roll surface jiga, by in and bring fast and, by close to the surface of the out material scraper to be scraped, by blocking plate knife plate, into the bucket, which constitute the grinding process.

The structure of the machine

1. Machine parts

The body adopts casting, is composed of a base and an upper cover plate, the body around the rail surface in a horizontal direction with double row spherical roller bearings in the bearing seat, fast slow, one on each side, and the upper cover plate and connected together in the roller bearing seat is connected by bolts, the fast and slow roller bearing by adjusting screw and the action of the spring on the upper cover, do before and after the move, the bearing seat for supporting a slow, fast three roller, right end device of roller shaft has a cooling water pipe and water tank, the left drive gear, the lower part of the body which is arranged between the motor and the slow roll and roll two side by the vertical roller center equipped with copper with the knife feeding, fast and close to the front surface of the cylinder is equipped with a blade member with the material, which consists of three roller grinding machine.

2.Transmission part

The lower part of the machine seat is provided with a motor, through a triangle belt transmission, incoming fast and, by fast roller through the transmission gear to roll, and later transferred to the slow roll.

3.Roller

Roller is divided into fast, medium and slow the are composed of chilled alloy cast iron cast, at both ends of the pressure into a heat treatment of high-quality steel shaft head, the left shaft end is provided with a transmission gear, right shaft head intermediate through hole for the channel pore as a roller in cooling. Chilled rolls of not less than 15 mm, the hardness of not less than 70 shore hardness, surface precision grinding.

4.Feeding device

Into feeding device consists of a copper knife and copper knife holder, installed between the slow roll and roller ends, copper knife arc close to the slow, and two stick surface, to ensure that no material flow, using copper knife bracket bolt fixed on the body for adjusting the margins and disassembly and cleaning, copper knives should be often adjusted, provided for the roller surface close.

5.Cooling device

For the appropriate eliminating roller and the heat generated by friction after expansion effect of roller contact surface smooth, roller at the right spindle is equipped with cooling water pipes and pipe joints set in a rubber tube, through the water by the roller on the inner wall of the heat exchange, the original hole back into the water tank, into the sewer.

6.Discharging device

For a material discharging plate is installed on the body of a plate bracket, a plate with a blade, the plate adjusting screw makes the blade close to the fast and on the surface, edge fitting position should be is 5 mm higher than the roller center, to facilitate the smooth scraping through grinding attachment in fast and table on the surface of the material.

7.Pressure regulating device

Rotating the hand wheel, through the screw and the spring, to promote fast, slow roll along the guide rail before and after the move, in order to adjust the size of the grinding fineness.
