In order to improve the production efficiency, the preparation silo is arranged above the mixer, so that there is always a batch of the prepared materials waiting for mixing, which can increase the production efficiency by 30%, so as to reflect the advantages of the high-efficiency mixer. Secondly, the material will form a gas arch and it is difficult to cut the material. The silo should be equipped with a flow-assisted air cushion or a vibration motor. For maintenance and sealing, the silo port should be equipped with a pneumatic or manual valve. In order to smooth the material, the cone angle of the silo cannot be greater than 60 degrees.
In order to fully embody the advantages of the high-efficiency mixer, a premixed silo is added, and a vibrating motor or a flow-assisted air cushion is arranged according to the size of the silo to prevent material bridging; a pneumatic butterfly valve is arranged at the connection with the mixer, and the sealing performance is good. Effectively control dust; the admixture feeding hopper is equipped with a dust collecting port to solve the problem of dust flying when the valve is opened.
