sketches of various types of concrete mixing plants

Chapter 1 - Background | Mixing and Compaction

The rotation speed for a popular model of continuous mix plant (Astec 400 ton/hr double barrel plant) is 7.68 rpm (0.8 rad/s). This plant has a drum radius of 1.69 m (5.56 ft). The tangential velocity at the point of mixing for this plant is 1,352 mm/s. In a popular size batch plant, the pugmill is driven at a rate of 33.6 rpm (3.52 rad/s).

Common Types of Surface Mining Equipment - Sand & Gravel

Mix Trucks (Concrete) - When a concrete batch plant (or ready-mix plant) is located onsite, sand and gravel may be used in specific formulations to create concrete to meet a broad range of customer construction needs. Sand and gravel is mixed with cement to produce concrete for transport in mix trucks for local use.

RMC Plant and its components, Testing and Design Mix

PROBLEMS EXPERIENCED Some sites are just too far away. Generation of road traffic. Concrete's limited time span between mixing and going-off means that ready-mix should be placed within 10 minutes of batching at the plant. Slump loss is also a major issue in RMC which result in a loss to company as the buyer tends to reject the product.
