1. Type of Mixer There are several types of concrete mixers available in the market, including drum mixers, pan mixers, and twin-shaft mixers. Each type has its specific functions and capacities, which directly influence the price. For instance, a drum mixer, which is more common for small to medium-scale projects, is typically less expensive than a twin-shaft mixer, which is designed for high-capacity projects and can handle larger volumes of concrete.

The camshaft controls the timing of the opening and closing of the engine’s intake and exhaust valves. It is driven by the crankshaft through a timing belt or chain. The precision in the camshaft's motion is vital for optimal engine performance, as it ensures that the valves open and close at the correct times in relation to the pistons’ position. Variability in camshaft design can lead to enhancements in engine efficiency and power output.

The second number, 65, represents the aspect ratio of the tire. This ratio is a percentage that describes the height of the tire's sidewall relative to its width. Specifically, the sidewall height is 65% of the tread width. For the 285/65R20 tire, the sidewall height would be approximately 185mm (calculated as 285mm x 0.65). A higher aspect ratio usually indicates a taller sidewall, which can improve ride comfort and absorb shocks from uneven terrain. However, it may also lead to less precise handling compared to tires with a lower aspect ratio.
