Max-Flow - Annihilator Grinder System

The Max-Flow system contains two or more Annihilator grinders mounted side-by-side in a stainless steel retrieval frame in the headworks of a waste treatment system. The frame is engineered-to-order and pre-fabricated. It includes guide rails to permit the independent retrieval of each grinder for easy maintenance. Steel panels can also be inserted in place of a grinder to divert the flow to the remaining grinders during maintenance, eliminating the need for a diversion or by-pass channel. Stainless steel or FRP control panels can be installed to control the operation of each grinder independently using manual or automated control systems.

Better Performance

• More grinding capacity than the drum screens
• Patented cutter spacers that reduce the incidence of failure due to ragging
• Modular design extends the life of all the Max-Flow Grinder

Lower Initial Costs

• Lower initial equipment cost than either drum screens or bar rakes or screens
• Lowers upfront capital costs by eliminating diversion or by-pass channels

Lower Maintenance Costs

• Less clogging than either drum screen grinders or bar rakes or screens
• Less vulnerable to large debris damage that drum screens
• Less down stream maintenance issues due to greater particle size reduction

Lower Energy Use

• Control capacity by shutting down some of the grinders if not needed

• Sewage Lift Stations
• Wastewater Treatment Plant Head Works
• Pulp and Paper Recycling
• Food Waste
• Sludge Processing
• Screenings

The Max-Flow system offers the following features and benefits

Bar rakes and bar screens can clog even when raked, and drum screens can become clogged and covered with debris. Because drum screens are not as robust as grinders, they are more susceptible to damage from large, floating debris. Bar rakes or bar screens also allow some large particles to pass posing a maintenance concern for other process equipment or the requirement for additional equipment to deal with these particles. None of these issues bother the Moyno Annihilators operating side-by-side in a channel.

Fewer maintenance issues translates to lower maintenance costs. When maintenance is required, removing and replacing one grinder or one grinder cartridge is much easier and less costly than removing and replacing an entire drum screen grinder or its drum screens or grinder parts. Servicing bar rakes and screens can also be a costly exercise.

The Max-Flow system’s initial cost is often lower than competing technologies. If you are considering a new installation, the Max-Flow system’s cost advantage increases substantially with the elimination of the space and construction costs Custom Engineered Headworks Debris Handling System Lower Initial and Lifetime Costs, Save Energy, and Improve System Performance associated with by-pass channels, gates and controls to divert the flow during the maintenance of headworks equipment.

Very often waste treatment facilities do not operate at their maximum flow rates. When this occurs, floats or other flow monitoring devices can be used to reduce the number of Max-Flow grinders in operation. Bar rakes and screens and drum screen grinders generally operate continuously with little variation in their energy usage.

When compared to drum screens, the greater grinding capacity of the Max-Flow system means better performance in reducing the particle size of debris floating through your system. The Max- Flow system’s cutting efficiency and longevity is aided by the Annihilator’s patented cutter spacers which significantly increases the grinder’s cutting surfaces and significantly reduces the incidence of failure due to ragging.

Bar rakes and screens used at remote lift stations can be a messy, noisy, and environmentally objectionable operation. Processing debris under ground in the lift station with a Max-Flow system is a much better environmental choice.

Although all Max-Flow Annihilator Grinder Systems are engineered to meet specific customer conditions, there are some general system design guidelines as shown in the table below. Grinders can be installed in an in-line or a staggered or offset design to accommodate a variety of channel widths. The custom retrieval frame can also be constructed in a variety of lengths, with the most common lengths being 5 feet to 25 feet. The retrieval frame can be mounted in a channel or mounted to a wall.
