Macerating Units

OrbitGrinder

Rethought and improved.

The OrbitGrinder is a cutting basket macerator. It is based on a completely new macerating concept. This ensures better cutting results and a very long service life.

The OrbitGrinder

Effective operation

With the OrbitGrinder, we have completely rethought the principle of perforated disk shredding.

At the heart of the macerator are cutting blades arranged in a star shape, which rotate inside a round cutting basket. This new technology enables us to achieve a consistently good and even cutting quality at all points in the cutting basket.

The fluid containing solids is supplied to the OrbitGrinder. The fluid and the solids are conveyed to the Constant Cutting System where they enter the round cutting basket.

Inside the cutting basket, the cutting blades arranged in a star shape rotate over the surface of the cutting basket. The solids are shredded and flow radially through the cutting basket with the fluid.

The baffle plate ensures that the suction force of the pump is distributed evenly around the cutting basket. The flow through the cutting basket is homogeneous.

For maintenance work and to empty the debris collector, the quick-release cover is simply folded upwards.

Impurities that cannot be shredded are collected in the debris collector.

Constant Cutting System

Constant perfect cutting result

With an even cutting speed, automatic blade adjustment and pivoted cutting blades, the CONSTANT CUTTING SYSTEM ensures a consistently outstanding macerating result.

Automatic blade adjustment

The contact pressure can be readjusted individually for each blade. This is done completely automatically by a central adjustment unit which applies a constant pressure on the blades.

The blades lie perfectly on the surface, the cutting force remains constantly high for each blade and the cutting result is consistently good.

Ideal cutting speed

Conventional perforated disk macerators (on the left) operate with a cutting plate over which blades rotate. At the outer edge of the cutting plate [A] the circumferential speed is significantly higher than in the center [B]. This results in excessive wear.

The OrbitGrinder (on the right) has identical cutting speeds at every point of its blades. This ensures excellent macerating results and unprecedented service lives.

Pivoted cutting blades

The blades are pivot-mounted using a single-point suspension.

They lie perfectly on the surface of the cutting basket.

Benefits

Powerful, easy to maintain and perfectly matched

The OrbitGrinder can be perfectly integrated in any existing system. Thanks to different cutting baskets, rotational speeds and flow speeds, the maceration degree can be adjusted individually.

Endless power

The OrbitGrinder achieves capacities up to 1,144 usgpm (260 m³/h). With the heavy-duty version, working pressures up to 73 psi (5 bar) are possible.

Macerator Max. flow rate Max. working pressure Max. temperature
OrbitGrinder 260 m³/h 2 bar, 5 bar in the heavy-duty version 120° C

Customize individually

Cutting baskets with different hole patterns can be used in the OrbitGrinder. In combination with the flow speed and the rotational speed, you can adjust the maceration degree.

The conical geometry of the cutting holes improves the flow of particles. The hole edges of the cutting basket are constantly sharpened by the cutting blades. They remain sharp and guarantee a consistently excellent cutting result.

MIP® = Maintenance in Place

Easy maintenance within a few minutes

The OrbitGrinder is designed according to the Maintenance in Place (MIP®) principle. All maintenance work can be done easily and quickly at the installation site of the device. It is not necessary to remove the OrbitGrinder from the pipeline.

Only the quick-release cover, which is supported by a gas strut, is folded upwards. All wear parts can be accessed easily and replaced within a few minutes. The debris collector is removed and emptied. Any escape of liquid during maintenance work is prevented.

Flexible integration in your system

The OrbitGrinder can be integrated perfectly in almost any existing system.

The in- and outlet can be positioned to each other at different angles. The top and bottom parts of the OrbitGrinder are connected by screws. In order to change the angle between the inlet and outlet, the bottom part of the Orbit Grinder is disconnected from the top part and screwed on again in the desired position.

ATEX-compliant design upon request

The Börger OrbitGrinders can be used in potentially explosive atmospheres in accordance with the ATEX Directive.

The ATEX Directive 94/9/EC defines the prescribed technical requirements for equipment and protective systems intended for use in potentially explosive atmospheres in Europe.

Air Pollution Control Act

The OrbitGrinder can be built to be used for lawfully handling toxic and highly toxic media in accordance with the Air Pollution Control Act.

The technical guideline for air quality control is the German government's “first general administrative regulation under the federal Air Pollution Control Act”.
