Products

C.F. Nielsen offers a large range of products for briquetting plants, as can be seen on the following pages.

We offer the widest range of briquetting presses, including other equipment such as saws, dosing silos, packaging and after sales service.

The latest addition to our product program is CFN Engineering. We are now offering this service due to an increase in customer requests. As a result, we are able to offer a complete range of equipment for complete briquetting solutions. We co-operate with different partners and the concept is only offered in selected markets.

However the basis for establishing a complete briquetting solution always starts with the press, where the following factors should be considered:

  • The volume and type of waste that needs to be turned into briquettes
  • The preferred diameter of the briquettes
  • The purpose of the briquettes – whether they are for industrial use or for private consumers
  • The capacity of our machines will vary from the highest output for industrial briquettes to a 10-30% lower output for production of consumer type briquettes

C.F. Nielsen is regarded and we want to be regarded at the world’s leading briquetting expert. Due to this we will be adding more technology to our product program during the coming year. The expansion of our range will include hydraulic and screw presses.

Below some characteristics of the different presses, which will guide you to select the right press.

Mechanical presses

– Cornerstone for the C.F. Nielsen product range
  • Mechanical presses are typically used for large-scale installations from some 200 kg/h up to 3.500 kg/h for single line installations, but in principle 2 or more presses can be arranged in groups to establish production centers for a high tonnage per hour.
  • A mechanical press is designed as an eccentric press. A continuously rotating eccentric shaft connected to a plunger presses the raw material through a conic die. In mechanical presses the counter pressure required can only be adjusted by installing a die with a different conicity or different length
  • We market a wide assortment of different dies developed for different woods and briquette qualities. Adjustable dies that can be mechanically or hydraulically adjustable are also available
  • As the mechanical press is driven by an electric motor instead of a hydraulic motor, energy loss in the unit is very moderate and the output in relation to power consumption is thus optimized
  • The operating life of a mechanical press is considerably longer than for a hydraulic press. The briquettes made on a mechanical press can be used both for consumer briquettes and industrial briquettes. The density can be regulated, so that it is high for consumer logs and lower for industrial briquettes

Hydraulic presses

– a niche product for smaller to medium sized woodworking industries
  • Hydraulic presses can be divided into two main groups:
  1. The low-priced, complete briquetting systems with capacities ranging from 50 kg/h to 200 kg/h and usually produce round briquettes. Such systems are used for small-scale briquetting and preferably only for max. 7 operating hours per day
  2. In addition to these systems there are the professional systems with a capacity of 400 – 1500 kg/h and mostly for production of rectangular briquettes. These systems are built for continuous operation.
  • In the hydraulic press, the required pressure is produced by the hydraulic system. The specially designed hydraulic cylinder assembly makes the main cylinder release the compressed briquette once the required pressure is reached. The pressure can normally be adjusted via a regulator, meaning that all briquettes are compressed under the same pressure
  • The briquettes made on a hydraulic press are usually used as consumer briquettes. The density is lower than a mechanical press and due to this, do not burn as long

Screw presses

– now offered by C.F. Nielsen
  • Screw type briquette press can produce biomass briquettes with higher compaction, but it also has a high energy consumption for the process compared to mechanical presses.
  • After feeding, the material is conveyed to the briquette forming head by a revolving screw shaft driven by an electrical motor.
  • The screw shaft is the main part of biomass briquette press. The screw distance become smaller and smaller along the screw shaft to briquette forming head. With the decreasing screw distance, the material endures higher and higher pressure. Because of the shaft, there is a hole left in the center of biomass briquette column
  • Screw presses are usually available with capacity from 75 to 500 kg/h
  • Because of the high friction the mechanical wear on the screw press is high.
  • Due to the high density the briquettes are usually used for consumer logs with a long burning time. The high density also makes the briquettes suitable for carbonization
