Abstract

The invention discloses a ceramic composite grinding roller of a medium speed coal grinding mill, which comprises an arc-shaped lining board formed by casting high-chromium alloy, wherein the arc-shaped lining board is provided with a through hole inside which oxide, nitride or carbide ceramic rod is embedded via adhesive, the arc-shaped lining board and the ceramic rod form a metal ceramic composite plate, the metal ceramic composite plate is adhesively connected with a roller core via the adhesive, the metal ceramic composite plate is provided with a bolt through hole, the bolt through hole is internally provided with a bolt which is directly fastened with the roller core and coated with threaded adhesive, and a ceramic cover is inlaid above the head of the bolt. The ceramic composite grinding roller is reasonable in structure and outstanding in shear resistance, extrusion resistance and abrasive resistance.

Description

Medium-speed pulverizer Ceramic Composite grinding roller

Technical field

The present invention relates to a kind of coal pulverizer grinding roller.

Background technology

At present, domestic medium-speed pulverizer adopts the rich chromium cast iron cast to form to grinding roller, or directly at surface of the work built-up welding high-chromium alloy, reaching the elongated component purpose of friction durability, but because the production status environment is very abominable, higher extruding force, shearing force are born in the surface during grinding roller work, as its service life,, behind service wear, must be changed or repair, but life cycle is short at 8000-12000 hour, this can bring great inconvenience to ordinary production, greatly reduces production efficiency.

Summary of the invention

The object of the present invention is to provide the coal pulverizer grinding roller with cermet compositions a kind of rational in infrastructure, anti-shearing, anti-extrusion, that wear resistance is good.

Technical solution of the present invention is:

A kind of medium-speed pulverizer Ceramic Composite grinding roller, it is characterized in that: comprise the arc liner plate that forms by the high-chromium alloy cast, this arc liner plate is provided with through hole, be embedded with oxide, nitride or carbide ceramics rod with binding agent in the through hole, arc liner plate and ceramic rod are formed the cermet composite plate, cermet composite plate and roller core are bonding by binding agent, the cermet composite plate is provided with bolt hole, be provided with in the bolt hole with roller core directly fastening be coated with bolt with the screw thread binding agent, the ceramic embedded lid in bolt head top.

Roller core is made by carbon cast steel.

Advantage of the present invention is: (1) this grinding roller has good anti-shearing, anti-extrusion, performance such as resistance to wear; (2) this grinding roller roller core is connected more firm with cermet compound arcuate liner plate with bolt and binding agent; (3) this roller surface cermet compound arcuate liner plate is convenient to install, and also is convenient to simultaneously change or repair; (5) service life of this grinding roller be common grinding roller 2-3 doubly.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is a HP type coal pulverizer grinding roller schematic diagram.

Fig. 2 is a MPS type coal pulverizer grinding roller schematic diagram.

The specific embodiment

A kind of medium-speed pulverizer Ceramic Composite grinding roller, comprise the arc liner plate 1 that forms by the high-chromium alloy cast, the arc liner plate is provided with through hole, that shape of through holes can be is cylindrical, prismatic, taper etc., be embedded with oxide, carbide or nitride ceramics rod 5 with binding agent in the through hole, arc liner plate and ceramic rod are formed the cermet composite plate, cermet composite plate and roller core 6 are bonding by binding agent 4, and directly fastening with roller core by the through hole on the arc liner plate by the bolt 3 that is coated with the screw thread binding agent, the ceramic embedded lid 2 in bolt top.

Be provided with adhesive layer between cermet compound arcuate liner plate and the grinding roller roller core, and solid on roller core by bolt, and roller core is made by carbon cast steel.

During manufacturing:

(1) ceramic rod is installed in high-chromium alloy arc liner plate 1 through hole inside, when the arc liner plate is installed, adopts binding agent 4 that arc liner plate and roller core 6 are firmly bonded together.Above-mentioned pottery can adopt oxide, nitride or carbide, and the arc liner plate adopts high chromium alloy material to make, and roller core is made by carbon cast steel.

(2) in bolt hole with being coated with bolt with the screw thread binding agent with 1 firm being fixed on the coal pulverizer grinding roller roller core 6 of arc liner plate.

Claims (2)

1. medium-speed pulverizer Ceramic Composite grinding roller, it is characterized in that: comprise the arc liner plate that forms by the high-chromium alloy cast, this arc liner plate is provided with through hole, be embedded with oxide, nitride or carbide ceramics rod with binding agent in the through hole, arc liner plate and ceramic rod are formed the cermet composite plate, cermet composite plate and roller core are bonding by binding agent, the cermet composite plate is provided with bolt hole, be provided with in the bolt hole with roller core directly fastening be coated with bolt with the screw thread binding agent, the ceramic embedded lid in bolt head top.
