Common commercial concrete mixing station type

2019-03-07

Commonly used 北京pk10开奖 according to its mixing principle is divided into self-falling concrete mixing plant and forced concrete mixing plant two categories.

1, since the fall of concrete mixer

The principle of placement of the mixing cylinder is vertical mixing. As the mixing drum rotates, the concrete mixture falls freely in the bucket, stirred and stirred for the purpose of stirring. A self-propelled concrete mixer is used to mix plastic concrete and low flow rate concrete. The cylinder and the blade are less worn and easy to clean, but the power consumption is large and the efficiency is low. The mixing time of the self-drop mixer is generally 90-120 S / disk. This type of mixer has greater wear on the concrete aggregate and affects the quality of the concrete.

2, forced concrete mixer

There are several sets of blades on the mixing drum. When stirring, the blades rotate around the vertical axis or the horizontal axis, and the material is forcibly stirred until the mixing is uniform. Concrete mixers are ideal for mixing dry and hard concrete and lightweight aggregate concrete. It can also mix low-flow concrete, with the advantages of fast mixing speed, fast stirring speed, easy operation and safety. But the machine is seriously worn. High-strength alloy steel or other wear-resistant materials are generally required for lining, and are mostly used in centralized mixing plants or prefabricated plants.
A concrete mixer is a machine that mixes cement, aggregate and water into a concrete mixture. It mainly consists of mixing tank, feeding and unloading mechanism, water supply system, original machine, transmission, frame and support device.
