Drum shot blasting machineries come in many varieties to suit different industries and purposes.
Rotary drum shot blasting machine
The rotary drum blast machine is the standard machine that uses centrifugal force to clean up the workpieces. The basic parts of the rotary drum shot blast machines include feeding hoppers, separators, dust collectors, and blasting wheels. It works through the simple blast and recovery method. First, the tumbled media is propelled onto the target by a blasting wheel. Then after the blasting process, the blasted media gets recovered through an integrated separator. Then, the process goes back again and repeats.
Cylindrical drum shot blasting machine
The cylindrical drum machine is like a cabinet in which workpieces are returned to the operator on a conveyor belt. This type of drum shot blast machine is suitable for small and medium batches and offers a fully automatic or semi-automatic operating cycle. One advantage of this machine is that it can process a variety of workpiece shapes and doesn't require any additional handling equipment.
Drum shot peening machine
Drum shot peening machines are designed explicitly for shot peening operations. Shot peening refers to a process in which tiny shot spheres are blasted onto a surface to improve its fatigue resistance and increase its lifespan. The drum shot peening machine has an automatic workpiece loading and unloading system, which can improve productivity.
Drum shot blasting machine has multiple specifications as each machine is tailored for specific industries. Here are some key specifications to note:
Drum Size and Weight
There will always be an ideal size of an industry material that must be used in the blasting machine. Each blasting machine has an ideal drum diameter and size for easy entry, exit, and blasting of the industry material. Similarly, the blasting machine has a carrying capacity limit that is expressed in weight. Industries should go for the drum shot blasting machine whose weight capacity fits their blasting needs.
Production Rate
The production rate of the drum blasting machine is defined in terms of the number of parts it can process in a given time. Drum blasting machines with a higher production rate suit high-volume manufacturing industries.
Power Requirements
The effective energy blasting capacity of the entire machine will determine how much power is required to achieve that capacity. Shot blasting machines have different power requirements, ranging from low-kilowatt electric motors to several kilowatts.
Dust Collection System
Since shot blasting generates a lot of dust, every machine has a built-in dust collection system. This specification varies depending on the capacity and efficiency of the system. Drum blast machines with efficient dust collectors help to maintain a clean workplace and comply with environmental regulations.
Control System
Some machines have a simple control system for manual operation, while others have an advanced automated control system with programmable logic controllers for precise control and integration with other automated systems.
For the drum blast machine to serve its purpose well and last a long time, it is important to keep it in good condition. What is important is to know that the maintenance requirements will vary depending on the machine’s model and manufacturer. Always strive to do what the manufacturer of the machine, suggests.
In general, regular machine maintenance will include the following:
Regular Inspection
Users conduct frequent inspections of every part of the machine to identify any signs of wear, damage, or blasting media build-up. After the inspection, users should repair or replace parts that have any issues to ensure efficient blasting and prevent further damage.
Lubrication
The moving parts of the blasting machine should be greased regularly and as needed to allow smooth movement and reduce abrasive wear caused by friction.
Dust Collector Maintenance
If the machine has a dust collection system, the entire system should be maintained as the efficient functioning of the machine will affect the entire system. Regular inspection and cleaning of this part of the machine prevents clogging of filters and improves their suction capacity.
Blasting Wheel Maintenance
Users of drum blasting machines should periodically inspect and maintain the blasting wheels and their parts, which include the wheel hubs, bearings, and blades. Ensure all parts are free of the blasting media, clean, and working as they should. Replace all damaged parts.
Electrical and Control System Checks
Users should periodically check the electrical connections and control systems. Ensure all connections are properly working, fastened, and cleaned. This helps to support reliable automation and random control of the blasting process.
The applications of a drum shot blasting machine are diverse due to the wide range of industries that use steel and metal parts in their operations. The drum shot blasting machine is mainly used to improve the surface quality and finish of metal parts and components.
The machine is used in the following areas:
When choosing a drum shot blasting machine, considering certain features and parameters is crucial to selecting one that fits their unique needs.
Workpiece dimensions and capacity:
Users should consider the dimensions and weight of the workpieces they plan to blast. They should ensure that the drum blasting machine they intend to purchase could accommodate those dimensions and weights. They should also consider the workpiece capacity they would need per hour or per batch. They need to compare this with the blasting machine's capacity and ensure it can meet their production requirements.
Surface preparation requirements:
Users should consider the type of contaminations and the desired level of surface preparation. Different blasting machines have varying sizes of blast media ejection wheels. Users should choose a machine that can effectively remove the particular contaminants they deal with.
Machine efficiency:
This refers to the percentage of surface area covered per unit time of blasting, factoring in media type and machine configuration. Efficiency in a machine helps to determine production time. Users should consider the efficiency of different machines. And then, choose one that can adequately reduce their production time.
Machine controls and automation:
Users should consider the level of control and automation they desire in their blasting machine. Some machines may offer simple manual controls. In contrast, others provide advanced digital controls or automated blasting programs. They should choose a machine that matches their preferred operational style and production requirements.
Q1: What is the difference between a drum blasting machine and a tumbler blasting machine?
A1: The drum blast machine uses a drum to rotate the workpieces, while the tumbler blasting machine uses a circular container to tumble the components. Additionally, the tumbler blasting machine can be automated or semi-automated, but the drum blasting machine is mostly fully automatic.
Q2: What is the production capacity of a drum shot blasting machine?
A2: The production capacity of the machine will vary depending on the drum's size and the component's size. Typically, the capacity ranges from 200 kg/hr to 5000 kg/hr.
Q3: Which one is easier: wash or blast?
A3: Using the drum blasting machine is easier than using the washing machines and cleaning agents because nobody has to follow environmental regulations to use the machine.
Q4: What is the lifespan of drum shot blasting machinery?
A4: The lifespan of the machine lies between 10-15 years if it's properly maintained and occasional repair services are carried out.
