Granulator ring die
Strict material selection: Special high-chromium stainless steel is used, resulting in minimal variation in die hole diameter and high ring die output.
Professional hole layout: CNC software programming automatically lays out holes to ensure a reasonable opening ratio and strength.
Drilling process: High-speed, low-feed CNC multi-axis gun drills are used for machining, achieving a surface finish of Ra value of 1.6 or higher for the die holes. The ring die produces smooth material output, high hourly output, and good feed quality.
Vacuum heat treatment: Dedicated vertical large-diameter vacuum furnace, equipped with a high-precision computer temperature and control system. The die holes are free from oxidation, have minimal deformation, and exhibit uniform hardness.
pressure roller
Using 40Cr or 42CrMo as the base material, the precision forged blank undergoes a series of processes including normalizing, turning, gear hobbing, carbonitriding, heat preservation and tempering, precision grinding of the inner circle, and rust prevention treatment. The hardness of the quenching zone is HRC58-HRC62. The process is meticulous, and the finished products undergo strict quality inspection.
A variety of optimized tooth surface designs are available for users to choose from: herringbone tooth type, honeycomb round hole type, hole and straight tooth combination type, large spiral helical tooth type, ordinary straight tooth type, and through tooth type.
High-precision concentric grinding ensures precise fit between the inner circle of the pressure roller and the user's bearing, as well as the coaxiality requirements of the inner and outer circles of the pressure roller.
Eccentric shaft
Made of 40Cr steel, strictly following process requirements, the product undergoes rough machining, followed by heat treatment to HRC30-35, semi-finish turning and finish turning, and finally grinding to ensure product quality. The surface is treated with rust prevention and strictly inspected according to tolerances.
Pressure roller assembly
It consists of pressure rollers, eccentric shafts, inner and outer ash covers, elastic retaining rings for holes, spacers, and bearings. The bearings are either domestically produced or imported. Each part is strictly designed and calculated, and all components are made of high-quality materials. The finished products undergo strict quality inspection to ensure product quality.
sieve
The base material is made of high-quality cold-rolled steel plates from Wuhan Iron and Steel and Panzhihua Iron and Steel. The plates are precisely sheared and punched with high density. The process includes gas nitrogen heat treatment, heat preservation tempering and rust prevention treatment. The opening rate is 30%-40% for plates with diameters of 2.0mm and below, and 40%-48% for plates with diameters above 2.0mm. The finished products undergo strict quality inspection to ensure quality.
Hammer
Employing a spray welding process, these hammers boast an aesthetically pleasing appearance. The surface is sprayed with tungsten carbide, achieving a hardness exceeding HRC60, significantly improving wear resistance and extending service life by 3-5 times compared to conventional processes. The hammer blades are made of high-quality tungsten carbide alloy, ensuring quality and allowing for customization upon request; a complete range of models are available. Carbonitriding, quenching, and tempering treatments alter the internal metallographic structure, achieving a hardness of HRC58-HRC62 in the quenched zone. Surface rust prevention treatment ensures that the hardness of the non-quenched zone around the mounting holes is ≤HRC32. All hammer blades are shipped with counterweights, and the total weight error for each shaft (or group) is strictly controlled within 5g to guarantee dynamic balance during use.
E-5 Hammerhead
Utility Model Patent No.: ZL201520100356.2
The hammerhead blank is cast using a silica sol process and made of ZG270-500 material. Two alloy pieces are welded to the tail of the hammerhead to achieve secondary crushing of the material during the crushing process, thereby increasing the output and fineness.
The alloy used is CL35 or ZL10A Zigong alloy, with a smooth bottom surface, beautiful appearance, and complete models.
Split gear ring
Utility Model Patent No.: ZL2015201008458
Made of high-quality steel plate, rolled into shape by a plate rolling machine, and precision machined on the outer circle for more accurate dimensions; using Zigong alloy CL35 or ZL10A; oxygen welding and grinding for a more exquisite appearance.
Ø New split-type gear ring, easy to install and easy to replace;
By changing the angle of the toothed ring alloy, the direct impact surface with the hammer head is increased, the crushing efficiency is improved, and the service life is extended, thereby improving the crushing efficiency of the ultrafine pulverizer.
Ø Crushing and puffing feed/shrimp feed, with a maximum working life of up to 11,000 tons.
Wear-resistant plate split
Utility Model Patent No.: ZL201520100843.9
