USED KOMAREK GREAVES DH-300

Manufacturer Information
K.R. Komarek Inc.
K.R. Komarek is a manufacturer of briquetting, compaction, and granulation equipment for industrial material-processing applications. Komarek roll presses are used to densify powders, fines, and other compatible materials into briquettes or compacted products for easier handling, processing, storage, transportation, or downstream use.
The Komarek DH-300 is a heavy-duty two-roll briquetting press designed for continuous compaction of compatible bulk materials under substantial roll-separating force.
Description
Available for sale is an unused Komarek Model DH-300 heavy-duty two-roll briquetting press, built in 2022.
The DH-300 is designed to continuously compact compatible powders, fines, and bulk materials between two counter-rotating rolls. The press develops approximately 75 tons of roll-separating force, providing the pressure required to form and densify material into briquettes based on the installed roll configuration.
Rated throughput is approximately 2 to 10 tons per hour, depending on the selected briquette size, feed-material characteristics, bulk density, moisture, binder requirements, and operating conditions.
The machine accommodates rolls ranging from approximately 13" to 20.5" in diameter and 4" to 13" in width, providing flexibility for different production requirements and briquette geometries.
Power is supplied by a 75 HP motor, while material is introduced to the rolls through a gravity-fed configuration.
Potential applications include briquetting and compaction of carbon-based fuels, inorganic chemicals, mineral ores, industrial byproducts, metal powders, and other compatible materials.
Serial Number: 051740-1-1.

Frequently Asked Questions

What is the production capacity of the Komarek DH-300? The stated throughput is approximately 2 to 10 tons per hour, depending on briquette dimensions, material density, feed characteristics, and operating conditions.

How much compaction force does the press provide? The DH-300 is rated for approximately 75 tons of roll-separating force, making it suitable for demanding industrial briquetting applications.

What roll sizes can the machine accommodate? The stated roll range is approximately 13"–20.5" diameter x 4"–13" wide. The specific roll configuration and briquette pockets should be verified for the intended product.

How is material fed into the press? This unit is configured for gravity feeding. Feed characteristics and consistency should be evaluated to determine whether any upstream conditioning or metering equipment is required.

What materials can be briquetted? Potential applications include compatible carbon-based fuels, inorganic chemicals, mineral ores, metal powders, and industrial byproducts. Product testing may be required to determine the optimal binder, moisture, pressure, and roll configuration.

Can Aaron Equipment assist with shipping and logistics? Yes. Aaron Equipment can assist with loading and rigging coordination, domestic and international freight, heavy-equipment transportation, and logistics planning for briquetting presses and associated material-processing equipment.
