MIll diaphragms With innovative 
Monobloc design

Reduce energy consumption, increase efficiency: The installation of a diaphragm can increase the economic efficiency of a grinding plant enormously. The Monobloc® diaphragm developed by Christian Pfeiffer is highly stable, durable and particularly robust. According to the current state of the art, this type of diaphragm is considered the most sophisticated solution for modern grinding plants.

Advantages of the monobloc construction

1
1
Material flow control

Due to the material flow control and maximum particle size limitation of the diaphragm, the material remains in the first grinding chamber until optimum pre-comminution has been achieved and before passing into the second chamber.

2
Separation of air and material flow

The separation of air and material flow, a major development by Christian Pfeiffer, also ensures that so-called "dead zones" (zones without regrind) directly behind the diaphragm are avoided.

Monobloc construction

The structure of the Monobloc® diaphram design supports the mill cylinder and counteracts deformation. The slotted plates are welded to the framework, making the wall particularly stable.

Intermediate diaphragm monobloc

Due to the material flow control and maximum particle size limitation of the transfer partition, the material to be ground remains in the first grinding chamber until optimal pre-shredding and only then enters the second chamber. The separation of air and material flow, a major development by Christian Pfeiffer, also ensures that so-called "dead zones" (zones without regrind) directly behind the mill wall are avoided. The result is a significantly more efficient grinding process.

Discharge diaphragm
Individual adjustment to the grinding plant

The discharge diaphragm allows the ground material to pass, but retains the grinding balls in the grinding chamber. Christian Pfeiffer adjusts the diaphragm individually to the existing grinding plant, fixing it either on the discharge mill head or floating on the mill shell.

Open lifter diaphragm
For mills with integrated drying chamber

By means of the open lifter diaphragm, the drying chamber integrated into the mill tube is separated from the grinding compartment. The steel grades used can easily withstand the up to 400°C hot gases found in the drying compartment.

Double outlet diaphragm
For mills with central discharge

Mills with central discharge are fitted with a double outlet diaphragm. The material is transported from both head sides of the mill towards the diaphragm, then out through the openings in the mill shell.

A story of efficiency

Efficiency in grinding is our heritage and our future.
Since 1925.

Making grinding processes as efficient as possible is a science in itself – one to which we dedicate our entire expertise and spirit of innovation. From the invention of the first MONOBLOC diaphragm to the technical fine-tuning of the separator QDK. How we became what we are today.
