Wherein arranged between the cylinder block and bearing have dirty plates (fixed, blocked sewage turn). Seal side, dirty plates on the cylinder block and the file is opened between dirty dish outfall. ??? 3, characterized in that the inner wall of the barrel wear sleeve has a plurality of open groove wear, and wear groove by one end of the discharge port is not true: ??? 4, characterized in that the central portion of the mold coal rods have Convex guide. ??? 5, characterized in that the discharge openings wear sleeve and screw shaft friction surface coating blades have carbide powder. Heavy faithful stick machine specializing in the production of coal, coal rods extruder machine coal rods, sticks extruder coal, coal bar machine price, coal rods machine manufacturers, coal bar machine equipment, rods machine, coal bar machine model, Coal Hollow rods, high pressure coal stick machine, charcoal rods machine, coal rods and other equipment. Welcome to the new and old customers to visit. ??????? Coal bar machine, especially nitrogen fertilizer industry for pulverized coal into the ring rod extrusion of rods coal. At present, the use of nitrogen fertilizer industry, coal stick machine is a double screw extruder. It is the pulverized coal with water and about 16% of the bond, stir in the mixer evenly pulverized coal feed screw extrusion extruded rod into coal. This coal rods machine has a simple structure, a good advantage, but in the course of the S & P A problem exists between short life. Mainly: I, bearing no seal, bearing easily damaged; 2, cylinder wear; 3, a gate is easy to wear and easy to plug; 4, helical blade easy to wear, and all associated briquette plant will be a change bearings assembly methods and sealing ways to make reasonable force, to prevent water and dirt immersion bearing; 2, in the simplified wear sleeve lining activities; 3, in the discharge port lining wear sleeve, holding mold and coal separated from the discharge port, and becomes concave mold coal rods is convex; the pitch of the spiral vane gradually decreases from left to right, and the busy movement carbide wear-resistant surface coating layer in friction. .. Mainly from the base (16)) bearing, spiral tube rails sentence pepper evenly, the discharge port types, coal stick a) composition, the improvement of the site are: 1. The change to the way the bearing ends of the bearing hybrid assembly seat Block left for single row tapered roller bearings, the right of single row radial thrust ball bearings, this assembly form, than the original approach can withstand greater radial and axial forces. Moreover, in order to protect the bearings, to prevent water and dirt immersed in the bearing between the simplified and the bearing set three seals, which blocked sewage young cabinet, retaining dirt Lin, the seal Magic, meanwhile, blocked sewage board and the cylinder block between dirty dish pseudo opened outfall., Jane pepper evenly in turn help the lining wear and high selection intensity strong abrasion resistance material casting. The inner wall of the cylinder wear and turn to open a number of wear-mediated plant e, its wear me out by the end of the spout is justified. The role is filled with a layer of tip wear material within the phase, so that the material mutual friction, protecting the cylinder, at the discharge port lined with bars chess coal power and wear and anti-friction sleeve turn advised. In the discharge port side rod nut coal block mold, but also facilitate the demolition. To reduce drag, the center portion of the mold coal rods connecting the guide projection (18), to improve the wear resistance, the wear sleeve surface coating are carbide powder, the pitch of the helical spiral vane gradually increases from right to left small, in order to improve the abrasion resistance, friction surface coating on the blade carbide powder coal rods manufactured machine.
