The channel mixer is mainly used for mixing powder or wet materials, the different proportions of excipients mixed dry powder blend is widely used in pharmaceutical, food, chemical, electronics and other industries. Through channel mixer design improvements, and to ask the customers to the channel mixer in accordance with the use of rules to carry out routine maintenance, can greatly enhance its service life, saves a lot of maintenance costs for the enterprise.
Currently, many users in the powder / powder mixing equipment, a lot of choices vertical conical mixing equipment, but experts suggest that, due to the vertical cone mixer, there are many shortcomings, the repair rate is high, so the powder / powder or granular materials are mixed, they should choose the channel mixer, the mixing efficiency of the equipment, mixing good quality, the discharge time is short, less residues. But to choose and use the channel mixer need to note the following:
A. According to the daily production, selection of channel mixer. Due to the mixer each batch of material and processing time of about 10 minutes, plus the time of the materials and feed processing time of each batch of material can be 15 minutes, 1 hour continuous processing batches. If you choose each batch processing capacity of 100 kg of the mixer, then the process 400 kg per hour. The user can be selected according to their needs the channel mixer.
Two. According to the channel mixer works for stirring a mixture of the double helix with the ability to push the material in the opposite direction should be basically the same. Within the spiral with the pitch should be less than the outer spiral bands, to achieve the ability to push material consistent inner spiral with the pitch should be less than the outer spiral bands, the width should be larger than the outer spiral band, otherwise it would be material in one direction concentrated. Therefore, in the choice of channel mixer to pay attention to this point.
3. The gap between the design principles, channel mixer, spiral band and the shell can be 4 mm to 10 mm, the material can be mixed friction driven by all participants. However, due to the friction coefficient is not the same granularity and materials, make the various components of the materials to participate in mixing time is not the same, resulting in the heterogeneity of the product. Some manufacturers have been aware of this and the product has been improved. Attention to the machining accuracy, so the end reduce the gap to about 3 mm; another is the gap between the spiral belt between the spindle and the shell made of a position adjustable, can be regularly adjusted according to the amount of wear and the shell . In the choice of mixer, the product of these two forms is the best option. How to increase the life span of the channel mixer, and its basic operation is to have a good day-to-day maintenance practices. |
