Chemical mineral fertilizer high pressure auger feeding double roller compaction for briquetting

Product Overview

Description

Roller compaction for briquetting operating principle:

The dry granulator adopts two rollers compaction. Between 2 rollers, there is a gap. One roller is fixed and the other is floating. With the support of hydraulic pistons, the floating roller is pushed close to the other and the hydraulic system can has the action of compensation and protection. In the surface of the roller, it is profiled with plenty of die holes of "Eggs" shape. Feedstock (powders) is fed into the gap between two rollers by screw. With rotating in reverse of two rollers, powder are compacted into Final product directly.

 

In addition to high quality and consistency, dry roller compaction produces granules that are:

** More durable, for improved crush strength.
** Roll compaction produces consistent, irregular-shaped granules that "interlock" to reduce product stratification during shipping and handling.
** Highly flowable powders compared to powders that bridge and cake.
** Sized specifically to meet your precise product requirements. Roller compaction offers control and range of granule size.
** Dust free to prevent cross-contamination in the next stage of production. By converting your raw material to granule form, you greatly minimize dust that can cause health and production problems while decreasing maintenance costs.
** Easily handled, transported and stored because of increased bulk density and flow properties.
