Roller Sleeves, Roller Shell for Briquette Machine
Products Description
The roller shell used in a ball press machine is typically made of high-quality alloy steel and is designed to shape materials into specific sizes and shapes. The roller sheel is a critical component of the ball press machine as it is responsible for pressing and forming the raw materials into the desired shape and size. The roller shell is often designed with a specific pattern or texture to create a specific design or finish on the final product.

Features of roller shell for ball press machines
●Roller shell,made of wear resistant alloy raw material, processed from fine and heat treatment;
●Made of bearing steel, high hardness, good wearing resistance, long life, different tooth depth and shape at option;
●Tooth surface forms of roller shell, good to pelleting performance
●Frequently-used roller shell tooth form:honeycomb,scallop shape and scallop shape with edge banding
●Honeycomb,scallop shape, the two types of roller shell is mainly used in livestock and poultry feed pelleting.
●The advantage of honeycomb rolller shell is the even wearing of ring die, but coil performance is bad.
●Scallop-shaped roller shell features good coil performance, widely used among feed mills, but wearing of ring die is not even.
The machinery processing of roller shells
The machinery processing of roller shellfor a ball press machine typically involves several steps. Here is a general overview of the process:
Cutting and shaping: The selected material is cut into appropriate sizes, and the rough shaping of the roller begins. This can be done through various methods such as machining, forging, or casting.
Machining: The rough-shaped roller shells undergo machining processes to refine their dimensions and achieve the desired shape. This may involve operations like turning, milling, drilling, and grinding.
Heat treatment: To enhance the hardness and strength of the roller shells, they often undergo heat treatment processes such as quenching and tempering. This helps to improve their wear resistance and overall performance.
Surface treatment: The roller shell may undergo surface treatments to improve their surface finish and protect against corrosion. Common surface treatment methods include electroplating, galvanizing, or applying coatings like chrome plating or ceramic coatings.
Precision grinding: After heat treatment and surface treatment, the roller shells are precision ground to achieve precise dimensions and smooth surfaces. This ensures proper alignment and operation within the ball press machine.
Inspection and quality control: Throughout the manufacturing process, inspections are conducted to ensure that the roller shells meet the required specifications and quality standards. This includes dimensional checks, hardness tests, surface finish inspections, and other relevant quality control procedures.
Material of roller for ball press machine
The conventional roller skin of the ball press is mainly made of high-quality alloy steel, 23CrNiMoV, 9Cr3Mo and other steel materials. After heat treatment, surface hardening and other processing processes, the hardness, wear resistance and corrosion resistance of the roller skin are effectively improved.
Applications of roller for ball press machine
►Material Compression: Roller shells are used to compress the raw material, such as biomass, wood chips, sawdust, agricultural residues, or coal dust. They exert high pressure on the material, causing it to bind together and form a solid briquette.
►Size and Shape Formation: Roller shells help in shaping the briquettes. They are designed with specific patterns or contours that impart a particular size and shape to the briquettes. The roller patterns can vary, including cylindrical, pillow-shaped, square, or customized designs based on the application.
►Uniform Density: The roller shells ensure uniform density throughout the briquette by applying consistent pressure. This uniformity is essential for producing briquettes of consistent quality and characteristics.
►Binding Agent Distribution: In some cases, binding agents are added to the raw materials to enhance the briquette's structural integrity. Rollers aid in distributing the binding agents evenly throughout the material, ensuring effective bonding and strength in the final product.
►Self-Cleaning: Roller shells are designed to be self-cleaning to prevent the buildup of material residues or adhesives. This helps maintain the efficiency and effectiveness of the briquetting machine during operation.
►Adjustability: Some briquetting machines have adjustable roller shells, allowing for the production of briquettes with varying densities or sizes. By adjusting the roller pressure, different briquette specifications can be achieved to meet specific requirements.
►Wear Resistance: Roller shells are typically made from high-quality materials, such as alloy steel or special composites, to ensure durability and resistance to wear and tear. This is crucial for long-term operation and minimizing maintenance costs.
Maintenances
1. Pay attention to timely clean up the dust knocked down from the coal powder briquette machine. During the disassembly process, attention should also be paid to dust removal to prevent it from invading the moving parts of the machine.
2. Check the wear of the triangular lining, bearings, spirals, nozzles and other parts inside the machine body, clean them, and replace the bearing grease.
3. Open the inspection cover of the reducer to check the meshing and wear of the gears.
4. Check whether the foundation and safety bolts are loose, and tighten them.
5. If there is a large pressure change in the oil pressure of the oil cylinder, new oil should be injected in time. If the oil pressure system is found to be leaking during operation, it should be stopped immediately and restarted after the leak is repaired.
6. Worn parts should be replaced or repaired in time to avoid damage to other parts during continued use. The roller skin of the briquette machine is a consumable part. Check the roller skin regularly for wear and whether the roller skin is aligned. If the roller skin is found to be worn or misaligned, it should be replaced and repaired in time.
