Urea Hopper

The Urea Hopper is the dedicated feeding storage unit for panel glue-making workshops, used for temporary storage of granulated urea and accurate, quantitative dosing of urea raw material into the reactor, working together with the formaldehyde tank and reactor to complete UF resin synthesis.
Urea powder and granules readily absorb moisture, cake, and bridge, causing uneven discharge and erratic dosing in ordinary hoppers — leading to imbalanced glue ratios, excessive panel formaldehyde, and fluctuating bonding strength. This series of urea feeding hoppers adopts anti-arch blockage-clearing structures and closed dust-proof design, paired with weighing modules to realize accurate automatic urea feeding, stabilizing glue formulas. It is ideal for fully automatic glue production lines in particleboard and MDF plants.

产品描述

I. Core Product Advantages

1. Precise Feeding, Stable Glue-Making Formula

Weighing metering closed-loop feeding with minimal urea feeding error ensures constant formaldehyde and urea ratio, long-term stable urea-formaldehyde glue viscosity and free formaldehyde content, unified panel quality.

2. Anti-Blocking & Moisture-Proof, Eliminating Bridging Shutdown

Vibration arch-breaking + arc no-dead-end inner wall design prevents damp urea from caking and bridging, ensuring all-weather continuous discharging, avoiding reactor production interruption caused by material blockage and shortage.

3. Enclosed & Dust-Free, Improving Workshop Environment

Fully enclosed structure with no urea dust flying during feeding, protecting operators' health and complying with environmental workshop requirements.

4. Fully Automatic Linkage, Saving Labor

Can be connected to formaldehyde storage tank and reactor control systems, automatic proportioning feeding for the entire glue-making process, no manual feeding and weighing required, reducing labor costs and manual proportioning errors.

5. Less Residue, Easy Cleaning

Polished inner wall with no dead corners, no urea residual caking after feeding, can be quickly rinsed by opening the inspection port, preventing mixing of different batches of materials.

6. Non-Standard Customization of Specifications

Capacity 0.5mxc2xb3~8mxc2xb3 customized on demand, floor-mounted or high-position rack-mounted to adapt to glue-making workshops with different layouts.
