Steel drum shredder

Types of steel drum shredders

A steel drum shredder is a kind of shredder machine that belongs to heavy machinery. It has a severe cutting system that can tear down stout steel drums. Steel drum shredders come in two types, hammer and rotary drum shredders. Following is a brief description of each type.

• Hammer shredders have hammers that swing on drums to break them. The shredding system has a few hammers mounted on a rotor or disc. When the rotor moves, it strikes the drum with considerable force, which causes it to break into smaller pieces. Hammer shredders can deal with diverse materials and yield a high production output. They are suitable for medium- to high-volume operations.
• Rotary drum shredders have rotary drums with blades that cut the steel drum into bits. Blades on the rotor move against a flat screen. The flat screen determines the size of the final products. The rotary drum shredder can process a large volume of materials at a go. It is used in industries with large-scale production.

Specification and maintenance

Steel drum shredders are designed with specific parameters that impact their capacity, performance, and suitability for different applications. Here are some critical parameters of the heavy-duty steel drum shredder:

• Cutting capacity:

  This indicates the weight of the material that the shredder can get through in a given period, typically expressed in kilograms per hour (kg/h) or tons per hour. Higher cutting capacity allows for more efficient processing of large volumes of material.

• Cutting speed:

  This indicates how quickly the shredder's blades rotate, usually measured in revolutions per minute (RPM). A higher cutting speed enables faster shredding of materials, reducing processing time.

• Cutting blade design:

  Gear-like blades are fitted on a steel drum shredder. Each blade design has distinct features and functionalities. Some may have serrated edges for finer shredding, while others have straight edges for coarse shredding.

• Shredding chamber size:

  This indicates the dimensions of the shredding chamber, such as length, width, and height. A larger shredding chamber accommodates bigger and bulkier materials, providing flexibility for processing various material sizes.

• Shredding technology:

  Some shredders use single-shaft shredding, while others use multi-shaft shredding. In single-shaft shredding, a rotor with unique blades turns at a consistent speed to shred the material against a fixed bed-plate. Multi-shaft shredders, on the other hand, have four to six rotating drums with interlocking teeth that pull in, break apart, and then expel the material. Multi-shaft shredders are better suited to breaking down tougher materials.

• Noise level:

  The noise level produced by a steel drum shredder during operation, measured in decibels (dB). Steel drum shredders are noisy machines, and operators will have to wear hearing protection while around the machine. Suppliers of the machine may inform buyers that the noise level can go as high as 85 dB.

An improper operation can lead to a malfunction of the shredder, which in turn will have a damaging effect on the waste management process. Here are some maintenance tips to ensure a proper operation:

• Operating under guideline:

  Users of the steel drum shredder should read the user manual thoroughly and understand the advice provided by the manufacturer for optimal usage. Different shredders have unique features and requirements, so the operator needs to adapt to the specific recommendations.

• Inspect regularly:

  The steel drum shredder should conduct routine inspections to identify any potential issues early on. During the inspection, pay close attention to critical components like blades, bearings, and belts. Look for signs of damage, wear, or misalignment that may require immediate attention to prevent breakdowns or accidents.

Uses of steel drum shredders

The primary use of a steel drum shredder is to shred six-inch steel drums, but they can shred all types of steel. Industries that are recycling conscious are looking for ways to minimize their carbon footprint, and steel shredders are integral to this effort. When steel is shredded into smaller pieces, it becomes more manageable. It is also easy to melt steel in chunks as opposed to whole drums. Drum shredding machines can shred any steel for any production line of steel products to be used in any construction project. Fragments of steel are produced when steel shredders grind down steel, and these can be easily transported.

Steel drum shredders are primarily used in the following industries:

• Waste management: Drums are usually found in hazardous waste management facilities, and they must be processed accordingly so that the harmful material can be recycled or correctly disposed of.
• Metallurgical industry: Steel is fed into mills and smelters after being fed into a drum shredder. It incurs lower transport costs and is easier to process when it is in smaller shredded pieces.
• Furniture manufacturing: The furniture industry uses steel drum shredders to shred steel that is used to create steel tubing. Tubes are made when flat pieces of steel are bent to make cylinders.
• Construction: Shredded steel can be used as rebar or any other structural component.
• Automotive industry: Steel from automobiles that have been shredded can be processed further using a drum shredder. Steel fromvehicles is utilized in numerous manufacturing processes, including theproduction of new cars.
• Packaging industry: Marked, battered, and damaged steel drums from the packaging industry can be eliminated using a steel drum shredder. Doing so will incur cost savings and ensure that production lines, assembly lines, and storerooms are efficient.

How to Choose a Steel Drum Shredder

Consider the following parameters of the metal drum shredder by focusing on the needs of the industrial or business use:

• Drum shredder capacity: Select the shredder machine with the optimum feeder capacity to handle the specific monthly/weekly workloads. A drum shredder with a high capacity/throughput will slow down the shattering process, resulting in standby machinery and greater operational expenses.
• Level of automation: Decide upon the amount of labor involved in shredding and relocating the waste material for recycling. An automated drum shredder will remotely control the feeding and shredding process while a manual shredder will require labor to put in the material, monitor its shredding, and take out the shredded material.
• Blade quality: Select a drum shredder machine that has good quality blades that will handle the type of metal waste material being fed in. The repairs required and the costs of replacing the shredder blades can add significantly to the total expense of a drum shredder.
• Drum shredder design: Examine the design of the shredder to assess the space it will occupy and the power consumption that will impact operational costs. Innovative designs can minimize the area occupied and the energy used during shredding.
• Safety features: Ensure that the safety features offer protection from hazards arising from human interaction and internally due to any malfunction or accidental occurrence. This can include an emergency stop button, the machine's guards, and an anti-jam mechanism.

Steel drum shredder Q&A

Q1: What are steel shredder machines made of?

A1: Steel shredders are made of three main parts: frame, rotor, and shredding chamber. The frame is made of cast steel or thick steel plates welded together to form a sturdy cage that holds the other parts of the shredder. The global shredder market is projected to grow at a CAGR of 3.3% from 2023 to 2032.

Q2: How does a steel drum shredder work?

A2: The drums are crushed and then shred by hammers that swing loosely in a rotor. The hammer strikes the drum resizing it to fit into the chute. After that, the impacted material is passed through the screening area. A steel shredders screening area determines the final size of the material. The oversized pieces are sent back to the hammers for more shredding.

Q3: What are the different types of steel shredder machines?

A3: There are four main types of shredders based on the shredder shaft design and material. They include banana shredders, single-shaft shredders, double-shaft shredders, and four-shaft shredders. They vary in size and capacity.

Q4: What are the benefits of using a steel drum shredder?

A4: The benefit of shredding steel includes but are not limited to recycling steel, saving energy, protecting the environment, economic gains, and reducing waste storage.
