The new mills of series BICARMILL represent the answer to the demands of the customers:
For such scope, many innovative solutions in the operation system, in the system of opening and the maintenance have become necessary.
The result is the mill of series BICARMILL, an excellent and reliable product, in which you can "nd all the STM quality and experience.
The powered activated carbon, used for the reduction of the emissions of heavy metals, furans, dioxins, …, is dificult to treat mainly because of the weak sliding fluidity of the product itself.
There is the danger that the correct dosing isn’t respected because of the formation of bridges inside the installation or other. For avoiding this problem, considering the STM experience in this sector, we have decided to measure the passing flow of the reagent, by guarantying capacities from 0,5 Kg/h up to 100 Kg/h, with a mistake margin of ±2%.
The grinding process is achieved by the impact of the material particles against the grinding track and against each other.
The grinding chamber is divided into two sections each with its own grinding disc. The two discs are turning in different directions against each other thus generating the particle flow against the grinding track and against each other. This grinding method results in an optimised energy efficiency.

The grinding process is achieved by the impact of the material particles against the grinding track.
Working principle : A 360°rotating disc, utilizing the cylindrical grinding track of the grinding chamber, causes thematerial grinding and classifying process. The material enters the single grinding chamber from the top, due to this design the material flows through the grinding and classifier wheel.
The grinding of the material, fed from top into the grinding chamber, is achieved by using compressed air, blown in through centered injection points. The grinding process is achieved by the impact and grinding of the particles against each other. The integrated classifier selects the particles of the required size and returns unwanted particle sizes back to the grinding process until the required size is achieved.
The grinding is achieved by the material impact on the grinding tools, mounted to the grinding disc (fixed or oscillating), and the grinding track, which could be a sieve or partially a solid grinding track of special design.
The sieve acts like a classifier as it determines the particle size according to its hole diameter.
Consequently the final particle size depends on the sieve hole diameter and the number of revolution of the wheel.

The material is fed between one fixed and one rotating disc or between two discs rotating against other with steel pins whose number, dimensions and positions to each other can be modified according to the actual requirements. Impact grinding without product classifying. The particle size is defined by the space between the pins and by the number of the disc revolution.
Very often this mill series is used for cryogenic grinding.
The high pressure rollers, moved forward by the rotating grinding track, and the material crushing achieve the grinding process. The crushing pressure is adjustable in order to modify the material fineness and/or according to different material specifications. The integrated classifier rejects particles of unwanted size and returns them automatically to the grinding process until the requested size is achieved.
For the separation of minerals and chemical products in general, for material fineness up to “top cut” 2 micron
