Installation Space
Indoor Installation: If the mixer is installed indoors, the height of the workshop ceiling must be taken into account. There should be enough clearance above the mixer to facilitate maintenance, such as for lifting out components like motors or gears. Usually, at least 1 - 1.5 meters of space above the highest part of the mixer is recommended to allow for easy access to equipment for inspection, repair, and replacement of parts.
Outdoor Installation: In outdoor settings, factors like the local climate and potential for flooding also play a role. The mixer should be installed at a height to avoid waterlogging during heavy rains. Additionally, if there are any overhead power lines or other structures in the vicinity, ensure that the mixer's height does not pose a safety hazard.
Material Feeding and Discharging Requirements
Feeding: If the feeding system involves using conveyor belts, hoppers, or other devices to transfer raw materials into the mixer, the height of the mixer should be coordinated with the height of these feeding devices. For example, if a belt conveyor is used for feeding, the height of the mixer's inlet should be such that the conveyor can discharge materials smoothly into it without causing blockages or excessive spillage. This may require adjusting the mixer's height to match the conveyor's discharge height, which could range from a few tens of centimeters to several meters depending on the specific conveyor design.
Discharging: The height of the mixer should also be selected according to the requirements of the discharging process. If the mixed materials are to be directly discharged into a waiting truck or other transportation vehicle, the height of the discharge port should be suitable for the vehicle's loading height. For standard concrete mixers, the discharge height might be around 1 - 2 meters to align with the loading height of common concrete transport trucks. If the materials are to be transferred to an elevated storage silo or another processing unit, the mixer's height needs to be set to enable efficient transfer, considering factors like the height difference and the type of transfer equipment (such as pumps or pneumatic conveyors) to be used.
Maintenance and Operation Convenience
Operator Access: The height of the mixer should be convenient for operators to access control panels, add lubricants, and perform basic inspections. For example, the control panel should be at a height where the operator can easily reach and operate it without having to strain or use excessive ladders. A height that allows the operator to stand comfortably at the control panel, usually around chest - height to eye - height (about 1.5 - 1.8 meters from the ground for an average - height operator), is ideal.
Maintenance Accessibility: For maintenance tasks such as replacing worn - out blades, checking seals, or inspecting the internal structure of the mixer, a proper height is crucial. If the mixer is too low, it may be difficult to work on due to limited space. Conversely, if it is too high, it may require complex and expensive lifting equipment. A height that provides sufficient working space around the mixer and allows maintenance personnel to reach all components without excessive difficulty is preferred. This might involve having a platform or walkway at an appropriate height around the mixer for easy access to different parts.
Future Expansion and Compatibility
Expansion Plans: If there are plans to expand the production scale or add additional equipment in the future, the height of the twin - shaft mixer should be selected with foresight. For instance, if there is a possibility of adding a larger feeding or discharging system, or if the mixer might need to be integrated with more advanced control systems in the future, the current height should not limit these potential expansions.
Compatibility with Other Equipment: Consider the overall layout of the production facility and the compatibility of the mixer's height with other equipment in the production line. The mixer should fit in seamlessly with other machines such as crushers, screens, and storage bins, ensuring smooth material flow and efficient operation of the entire production process.
