There are various forms of plastic scrap from rejected parts, mouldings produced as a result of the manufacturing process, and blow-moulded, injection-moulded and rotational-moulded items. Manufacturers can reduce the material into smaller pieces that can be more easily handled for the next round of recycling or reuse, rather than having to contend with the handling difficulty this material presents. The role of a scrap grinder machine is crucial in this process as it efficiently cuts and grinds plastic scrap in a controlled manner.
However, the selection of the grinder isn’t just about picking the appropriate size motor or price for the machine. Equipment that suits the material, production quantity, production environment and maintenance requirements. If you are looking for a machine for investment, these are the seven factors you’ll want to take into consideration prior to making a purchase.
1. Understand the Type of Scrap You Need to Process
The first step to finding the right plastic scrap processor is to determine what kind of plastic scraps your facility produces. The waste may take different shapes and sizes depending on the production process and the grinder must be able to deal with the waste consistently.
Blow-moulded products, for example, might need to be manufactured, injection-moulded components might need to be manufactured, rotational-moulded products might need to be manufactured or plastic pipes might need to be manufactured. India Roto Plast comes with a range of Scrap Grinders suitable for such materials including CPCV/UPVC pipes.
The knowledge about the material you are going to use will help you to choose the right equipment for your actual use and not just by looking at the specs.
2. Check the Required Grinding Capacity
Also important is production volume. If the scrap generation rate is large, the machine size may become a bottle neck, and if the size of the machine is too large, investment and operating capacity may be wasted.
Check the amount of scrap produced by a facility per hour or shift. Next, compare this requirement with the grinding machine’s expected output.
India Roto Plast are available with models ranging from IRP-SG-12 (40 to 50kg/hr.) up to IRP-SG-36 (400 to 450kg/hr.). Intermediate models offer capacities in between these ranges.
This range provides buyers a way to look at the production needs of their operation and choose an appropriate machine.
3. Pay Attention to Blade Design and Quality
The grinding performance is directly influenced by the cutting system. Blades require repeated contact with plastic materials and must have an effective cutting action.
Keep an eye out for a machine that has the right type of hardened rotary knives and blades. It also has the advantage of easy blade adjustment, which can facilitate the maintenance process and ensure stable grinding performance throughout the use of the device.
India Roto Plast claims that its scrap grinders have specially designed rotary knives and grinding knives of special alloy steel and have an adjustment facility for the knives.
When comparing machines, therefore, don’t overlook the construction and arrangement of the cutting components.
4. Consider Machine Construction and Stability
When a grinder is to be used regularly in an industrial setting, it must be stable when in use. Too much vibration can cause operator discomfort, machine performance and impact on other equipment around the machine.
A robust structure and a good balance of the machines can help to ensure smoother running. India Roto Plast emphasises on its scrap grinder range to offer features like robust construction and lower vibration of machines.
Think about the placement of the machine and how often it will be used before you buy it. A machine to be used on a regular basis in industry should be able to handle the routine demands of the production process.
5. Look at Feeding and Maintenance Access
The feeding of the scrap into the grinding machine should be easy and the routine inspection and maintenance should not be unnecessarily complicated.
A realistic feeding system can increase the ease with which workers operate the system everyday. Meanwhile, available access to parts of the machine will help minimize the work involved when cleaning, inspecting or servicing the machine.
India Roto Plast’s Scrap Grinder comes with a feeding attachment for easy opening and maintenance.
Minuteman 2015 will be much more noticeable once the machine is a regular part of the production process.
6. Think About Long-Term Operating Requirements
Buying price is not all that is part of the investment. Blade life, blade maintenance, blade adjustment, downtime, and the overall durability of the machine are other factors that buyers should consider.
Recurring needs for scraps processing can be more efficiently handled with a machine that is designed for long operation. India Roto Plast says its scrap grinder can be operated for long time and maintenance free.
Another good idea is to talk to the manufacturer prior to ordering regarding spare parts, maintenance plans, installation needs and technical support. All these may affect the actual usefulness of the machine during its life.
7. Choose the Right Scrap Grinder Machine Manufacturer
Last, but certainly not least, take into account the experience and expertise of the manufacturer of the machine. It is more useful for a manufacturer who has some knowledge in plastic processing and all pertaining equipment to understand the relationship between the amount of scrap produced, grinding and overall production process.
India Roto Plast is a manufacturer and exporter of Rotational moulding Machines and Ancillary equipment like Pulveriser, Extruder, Scrap Grinder, Table Cutter, and Mixer. According to the company, they have been specializing in the rotomoulding industry for over 11 years and based in Ahmedabad, Gujarat.
Therefore, by selecting an experienced Scrap Grinder Machine Manufacturer, the buyer will be able to obtain the equipment designed based on actual industrial applications, and the knowledge and information which are beneficial to the buyer’s equipment selection and operation.
FAQ’s
A scrap grinder machine is used to reduce plastic production scrap into smaller pieces through a cutting and grinding process. The processed material can then be handled, recycled, or reused depending on the application.
The suitable material depends on the grinder design and application. India Roto Plast states that its machines can be used for blow-moulded, injection-moulded, and rotational-moulded products as well as CPCV/UPVC pipes.
The blades perform the primary cutting action, so their design, material, and adjustment can affect grinding performance and service life. Hardened alloy-steel knives and convenient adjustment can be useful features for regular industrial operation.
Make Your Scrap Processing More Practical
A scrap grinder is more than just another piece of equipment in the production area. It can be used to help manufacturers handle plastic waste and minimize production scrap when properly selected along with preparing material for additional processing or reuse.
Prior to your investment, consider the type of scrap to be processed, the required capacity, blade construction, machine stability, feeding, maintenance and manufacturer experience. When considering the equipment, you should consider these things in order to select the equipment that is suitable for you and your production requirements, rather than the biggest or cheapest equipment.
India Roto Plast provides a variety of scrap grinders to the manufacturers with various output capacities and blade sizes, which will be suitable for different plastic scrap application.
