The Model 496 Short Center NFPA rated Gravimetric feeder is designed to meet your needs when feeding a pulverizer. It was specifically designed for replacement of volumetric feeders where there is a short dimension from the center of the bunker outlet to the center of the pulverizer inlet. It is designed with the operator in mind to give years of trouble free operation. MERRICK has served the power industry for over 2 decades with over 1000 worldwide installations. This core experience coupled with world-class expertise in electronic control systems and extensive understanding of the power industry has enabled Merrick to design a truly unique coal feeder.

The Model 490 NFPA rated gravimetric feeder is designed to meet your needs when feeding a fluidized bed boiler or other system needs requiring a low pressure, sealed feeder. It is designed with the operator in mind to give years of trouble free operation. Merrick has served the power industry for over 2 decades with over 1000 worldwide installations. This core experience coupled with world-class expertise in electronic control systems and extensive understanding of the power industry has enabled Merrick to design a truly unique coal feeder.

The Model 970 can be designed for a 12” or 24” belt. Both belts are designed to meter various materials into a process at a designed feedrate with gravimetric precision.The feeder belt speed is varied to deliver material from a supply device into a process at a desired rate. A weight signal output and speed signal output are supplied for closed-loop process control.

- 18' to 42' belt width (up to 300 t/hour)
- 42' to 72' belt width (up to 2,000 t/hour)

Introducing the MERRICK? Model 450 Weigh Feeder. Whether you are moving coal, minerals, agrichemicals, food stuffs, ores, or a variety of other bulk materials, the Model 450 is designed to handle them in the roughestapplication environment. Durability is assured, over years of continuous service, through the use of oversized components and the sturdiest construction.

A Loss-in-Weight Feeder is a device or collection of devices, which receives material from an upstream supply and meters that material into a downstream process at a set feedrate based on feedback from a weigh sensing device.

- USDA / Dairy 3-A version available

- Heavy Duty Construction
- Cantilevered frame – easy belt replacement
- 18” to 48” Belt widths
- Capacities to 500 STPH
- Lengths up to 20 ft

The MERRICK Acoustic Flow Monitor was developed to provide a reliable method of detecting material flow or flow interruption in pipes or downspouts. Unlike other instruments that detect only the presence or absence of material at a certain point in a pipe, the MERRICK Acoustic Flow Monitor detects the actual flow of the material. It can therefore alert the user to a pluggage above, below or anywhere in the pipe. It is particularly suited installations where, due to licensing or administrative restraints, nuclear type detectors are impractical. When mounted above a feed system, the detector can provide a reliable alarm signal in the event that a flow stoppage occurs.

KNIFE GATE VALVES

MERRICK Knife gate valves can be utilized as isolation valves located at the feeder outlet, pulverizer outlet or in the burner line at the furnace face. These valves provide “off-on” control of the material of varying sizes.

BUNKER OUTLET VALVES

MERRICK Coal valves are utilized as material shutoff gates located at the bunker (silo) outlet. These valves provide “off-on” control of the material of varying sizes. They are designed to cut through a standing column of material.

Genetix is MERRICK’s latest line of Process Controllers for weighing and feeding equipment. Genetix consists of a single-board process controller with more capabilities and customer flexibility than most other larger, bulkier controllers. The Genetix Core Module (GCM) can be configured with various displays and interfaces allowing it to perform well for a simple scale installation or a complex multi-feeder system.
