Fixed Bin Powder Blender Introduction

Hywell Machinery's fixed bin blender is used for the homogeneous mixing of powdery substances with different specific weights and particle sizes. The production process is hygienic and dust-free because the product is mixed in independent containers of variable sizes. During the mixing process, the powder moves in a random direction from the center to the end of the trough and at the same time from top to the bottom. In such a multi-dimensional way. the fixed bin powder blender also named as square cone mixing machine. 

Materials are charged into a closed square-cone mixing barrel, and the symmetrical axes of a hopper and the axes of the rotating shaft form an included angle, materials with different constituents are strenuously rolling over in the closed hopper and producing high shear to achieve the best effect of mixing. For the materials, there is no centrifugal function, without the specific gravity segregation and layer division. For each build-up phenomenon, there is a remarkable weight rate. The mixing rate is high. The material charge rate of the barrel is big. The maximum rate can be up to 80%. The barrel adopts arc shape connections and is well polished and reaches GMP.

Hywell Machinery has the lab scale powder mixing machine for the factory or experimental agency product development stage, please pay attention to hywell company's laboratory Square cone mixer.

Fixed Bin Powder Blender Working Principles

During the mixing process, the powder moves in a random direction from the center to the end of the trough and at the same time from top to the bottom. the HF series powder mixing machine needs only a short mixing time and relatively low power consumption. The mixer‘s “Gentle” mixing action is good for final products that are sensitive to the high shear of the mixer and tend to break or reduce their particle size, or are highly abrasive. it can discharge load by vacuum feeder .


The fixed bin mixer is composed of a machine base, driving system, control system, mixing bin, and so on. When it works, after materials are fed into the bin, lock the feeding cover. Set the blending time and blending speed according to your process requirements. Start the control system, and start the blending operation. When the set time is reached, the equipment will stop automatically. The printer can print the records according to the set items and process parameters.

In the Fixed Bin Powder Blenders, the whole process adopts PLC and interface automatic control system, guaranteeing homogenous blending. The process parameters can be recorded and printed for each batch. you can analyze and monitor the blending processes of the bin blenders. The highly sensitive infrared sensor device ensures the safety and prevents the wrong operation. Inside of the pharma bin smooth without dead corners and mixed in a sealed space to avoid dust and cross contamination, realizes dust-free production.

Fixed Bin Blenders are widely used in the pharmaceutical industry mainly for the mixing of granules and powder. Meanwhile, it can be widely used in as raw material industry, chemical industry, foodstuff industry, etc. It has the advantage of stable transmission, reliable structure, large mixing amount, and homogenous blending for dry granules and powder.
