DESCRIPTION

North Ridge TG Terminator Grinder

Accepted Flow Rate	Up to 100m³/hr
Drive Options	Electric Motor

The North Ridge TG Terminator series of inline grinder is designed to macerate solids before they enter the pump.

This grinder is available in three versions depending on application requirements. The TGR standard version is a cantilever design. The TGS version is installed with a second bearing housing and is designed for heavy duty applications. The TGC version comes complete with a stone catcher to stop any stoned entering and damaging the pump.

The main benefits of installing the TG Terminator grinder are as follows:

• Protect the pump from damage from unwanted solids

• Increase the lifespan of any components subject to wear

• Protect any equipment sensitive to damage from hard or abrasive solids

• Reduce the risk of any possible blockages

• More product is pumped through maceration than screening, there is therefore less process waste

• Reducing solids content increases the quality of the process

• It is possible to install smaller pipework and a smaller pump, therefore reducing costs by grinding large solids

• Shorter pump run cycles, therefore lower electrical power consumption

FAQS

Why Use a Grinder?

Dual shaft grinders are used to protect pump or equipment downstream from damage from unwanted solid. It allows smaller pipework to be utilized reducing installation costs, as solids are pulverized to a few mm.

What accessories are required?

Ideally a grinder should be connected into a control panel with an automatic reverse function upon overload to protect the motor from damage and allow automatic unclogging.

Screening Vs Grinding

Screens often require frequent manual cleaning, with automatic versions requiring little or no maintenance. Care should be taken during winter as screened material can freeze during cold temperatures clogging the flow, leading to flooding which requires manual intervention. During cleaning, due to the lack of backpressure, surging can occur downstream. Whilst manual versions are inexpensive, automatic screens are expensive with neither removing grit.

Grinders eliminate the need for screening, handling and disposal. They can handle large solids, as well as stones, with a facility for grit removal. Cost savings against traditional screening are significantly higher.

One of the disadvantages of grinding is that as they will grind any solids which enter the unit, synthetic material can cross contaminate the segregated waste which is often reused in soil which can lead to batches being rejected if synthetic material entry cannot be controlled. There can also be an associated increased plastic build up in digestion, and rag accumulation on air diffusers.
