Block making machines are useful equipment for manufacturing concrete blocks on a large scale. This blog post provides a complete overview of concrete block making machines, including the types, workings, factors to consider and more.
ประเภทของเครื่องทำบล็อกคอนกรีต
There are mainly two types of concrete block making machines:
• Manual machines – These are small, inexpensive machines that are operated manually. An operator physically adjusts the molds, pours concrete and removes finished blocks. They have low production capacities of around 50-150 บล็อกต่อวัน.
• Automatic machines – These large commercial machines are fully or semi-automatic. They have a continuous process with automatic mold movements, concrete dosing and block removal. Automatic machines can produce 400-1500 บล็อกต่อวัน.
How Concrete Block Making Machines Work
The basic working of เครื่องทำบล็อก involves the following steps:
• Molds: The machine contains steel molds in the required block sizes and shapes.
• Feeding: Dry ingredients like sand, cement and aggregates are fed into the machine in a precise ratio.
• Mixing: The dry ingredients are mixed with water in a revolving pan or drum to form concrete mix.
• Filling: The concrete mix is filled into the open molds using dosing chambers and conveyors.
• Compacting: A ram or vibrating plate compact the concrete in the molds to remove air gaps.
• Curing: The filled molds move to the curing area where the blocks harden for a few hours.
• Demolding: Once cured, the finished blocks are ejected from the molds either manually or automatically.
• Transport: The blocks are then transported for storage using conveyors or forklifts.
Factors To Consider When Buying A Block Making Machine
When choosing a block making machine, consider the following factors:
• Production Output – Higher production capacities mean the machine can produce more blocks per day, improving efficiency and profitability. Consider the optimal output needed for your business.
• Block Dimensions – Check that the machine can manufacture blocks in the specific lengths, widths and heights required for your applications. Larger dimension ranges offer more versatility.
• Automation Level – Fully automatic machines require less labor but have a higher initial cost. Consider your budget and labor requirements to determine the optimal level of automation.
• Mold Materials – More durable materials like steel typically last longer but cost more. Less expensive options like aluminum can suffice if replacement molds are budget-friendly.
• Electrical Requirements – Ensure your electrical supply can meet the power demands of the machine to avoid issues during operation. Larger, automatic machines require higher power.
• After-Sales Support – Robust warranty coverage and convenient customer support can minimize downtime caused by any machine issues. This impacts the longevity of the investment.
• Build Quality – Higher quality materials and construction translates to a longer lifespan and lower maintenance requirements over time. This reduces operating expenses.
• Cost – Compare the machine’s price relative to its capacity, features and suitability for your needs. Aim for the optimal balance of value and affordability.
