Principle of continuous mixer

overflow method, Advance and retreat supplies method

Overflow method:

based on discharge control, certain amount of filler is kept in the mixer tank during the continuous mixing process, and this certain amount of filler is mixed with new filler, alternating and superimposing activity make this part of the material maintain the condition of discharge, material coming out with overflowing.

Advance and retreat supplies method:

based on the mixing agitator, agitator can achieve force of synchronous or alternating of feeding and retreat. Three methods: more feeding less retreat, less feeding more retreat, equal between feeding and retreat can be chosen based on the mixing process and nature of the materials.

Working conditions of the continuous mixer

1. The material should be supplied steadily and continuously by the feeding system

2. The feeding speed of different materials should be subject to the formula proportion

3. The materlals after mixing should be timely and efficiently processed by the next equipment, any block is forbidden

4. Little additives like below 5% content proportion should be mixed with bulk material beforehand.

5.  The feeding speed decides the output of continuous mixer, the output, uniformity and properties of material decide the type and size of mixer.

STRUCTURE CHANGE:

1. Continuous mixer has single shaft and two shafts structure according to different material and different output.

2. the paddle blades can change into removable ones, which decrease the replacement costs after the blades worn out.

3. To realize the technical of drying, cooling and keeping warm, the mixer can be added a jacket structure out of the tank. Hot water or steam or industrial oil can circulate in the jacket. Liquid filling system can be installed at the top cover. The different material of the atomized spray nozzle can realize the injecting of acid or alkali liquid.
