The characteristics of horizontal mixer and the skills of selecting high speed mixer

A mixer is a machine that uses mechanical force and gravity to mix two or more materials evenly.

Characteristics and application of horizontal mixer

Horizontal mixer discharge mode: powder material adopts pneumatic open door structure form, has the advantages of fast unloading, no residual, high fineness materials or semi-fluid materials using manual butterfly valve or pneumatic butterfly valve, manual butterfly valve is economical and applicable, pneumatic butterfly valve has good sealing performance on semi-fluid, but the cost is higher than manual butterfly fly. In the case of heating or cooling, can be equipped with jacket. There are two heating modes: electric heating and thermal oil heating. Electric heating is convenient, but the heating speed is slow and the energy consumption is high. Heat conduction oil heating needs to configure oil pan, oil guide power, pipeline, large investment, but fast heating speed, low energy consumption. Cooling process can be directly injected into the jacket cooling water, jacket heating area, cooling speed, motor and stirring spindle through cycloid gear reducer direct connection, simple structure, high reliability, convenient maintenance. Mixing machine is used in pesticide, veterinary medicine, food, chemicals, biology, aquaculture, ceramics, refractory materials, plastics, fertilizer and other solid solid (powder and powder) solid slurry (powder and glue slurry), but also especially suitable for thick boring mixing.

Tips for choosing a high quality high speed mixer

1. Select bench mixer according to daily production. Because the processing time of each batch of materials in high-speed mixer is about 10 minutes, plus the time of discharging and feeding, the processing time of each batch of materials can be calculated as 15 minutes, so 4 batches of materials can be continuously processed in 1 hour. If you choose a high speed mixer with a processing capacity of 100 kg per batch, it can process 400 kg per hour. Users can choose horizontal high speed mixer according to their own needs.

2. According to the working principle of horizontal spiral belt type high-speed mixer, the ability of the double spiral belt used for stirring and mixing to push materials in opposite directions should be basically consistent. Since the pitch of the inner spiral belt should be smaller than that of the outer spiral belt, in order to achieve the same ability of pushing materials, the pitch of the inner spiral belt should be smaller than that of the outer spiral belt, and the width should be larger than that of the outer spiral belt, otherwise the materials will be concentrated in one direction. Therefore, attention should be paid to this point when choosing horizontal high-speed mixer.

3. According to the design principle, the gap between the spiral belt and the shell in the spiral belt type high-speed mixer can be 4 mm ~ 10 mm, and the materials can be driven to participate in the mixing by friction force. However, due to the different particle size and friction coefficient of materials, the mixing time of various components of materials is not the same, resulting in uneven product. At present some manufacturers have realized this point and made improvements to the product. One is to pay attention to the machining accuracy, so that the bottom gap is reduced to about 3 mm; The other is to make the position between the spindle and the shell adjustable form, according to the amount of wear can often adjust the gap between the spiral belt and the shell. These two types of products should be the best choice when choosing high speed mixer.

4. When choosing horizontal spiral belt type high-speed mixer, pay attention to the discharging mode. Should communicate with the supplier in time to choose the valve form suitable for their own process, at the same time do not choose the side outlet form. The reason is that: when the high-speed mixer finishes mixing and mixing in the specified time, the material uniformity can be guaranteed by discharging it once in a short time. If the side mouth spiral belt is gradually released, one is to delay the time and not reach the expected productivity, and the other is that the material has reached the best uniformity, excessive stirring will make the material segregation instead, destroy the uniformity, so as to lose the significance of choosing horizontal high-speed mixer.
