The fluidizing bed blending silo is suitable for the mixing of fluidizable bulk materials with particle sizes of less than 500 μm, such as powder. It is used in batch operation. Go To Product Direct Inquiries. Multi-Channel Multi-Channel blending silos are ideal for free-flowing bulk materials such as pellets. ...
The main advantage of Flat Bottom Blending Silo is less number of extraction gates and thereby less maintenance. The central outlet is provided with Koenig Manual Slide gate for maintenance followed by aerated junction box, Koenig Flow control valve and Pneuslide system to feed to the Koenig Bin weighing system. Standard Silo sizes are ⌀14m ...
Silo cone blenders for efficient blending. A uniform blend is an important factor for meeting the highest standards of product quality. To meet these standards Coperion & Coperion K-Tron have developed static blending …
Air blending is achieved by use of a porous membrane over the entire bin bottom, 4 air plenums and a simple flow control system enable. Together they change the density of …
Blending silo with pipe blender. The pipes, arranged on the outer wall of the blending silo, have different nominal diameters. Because of the specially constructed product inlets, the product is pre-mixed both when it flows in and out of the mixing pipe. The different pipe diameters and lengths create a varying speed and flow profile in the pipes.
The homogen ization process starts during the filling of the blend ing silo. After filling the blending silo, the homogeni zation process continues for about one hour. The filling time of one blending silo and thus the silo cap acity is approximately equal to 6- …
A simpler and cost effective alternative is to use the silo as a blending system it self. The design can allow for either continuous or batch blending systems. The Silo Blending / Mixing systems provide an unprecedented technique of blending or mixing products. It combines high quality of blending / mixing that eliminates heat development ...
Dear all,Currently we have been working on Silo design and calculation.As for Blending Silo, we normally apply Combi-Flow Type Blender.In this case, it is hard to get complete blending within 2 cycles
A typical silo features a cone-shaped design, which helps you gain control of the bulk material flow. If pneumatic conveyors are in place to remove the bulk materials, then a conveyor tube is attached to the bottom of the silo, to ensure no product is wasted and that the process is more streamlined.

Silos design according to Handbook of Concrete Engineering and SNI 2847:2013. From the data do initial design planning by determining the main dimensions of prestressed silos structure. The early stages of planning is the calculation of plates, beams, and skur. Furthermore, the calculation of reinforcement structure Silo.
The Tangential Blending Silo stands out due to its unique aeration floor that covers almost the entire ring area, thus ensuring optimum aeration of the raw material. The material can be fluidised and discharged at all points in the silo floor area. The aeration floor has a modular and compact design. Assembly is easy, safe and therefore cost ...
Blender selection and design depends on several factors, including the properties of material to be blended. Bulk density of material is one of the most important physical properties of material to be considered while designing blenders. This article provides definitions of the different types of bulk densities and explains the differences between …
In this work, the wall normal stress and the discharging characteristics of the granular material of gravity blending silo were numerically studied.
