Apron weigh feeder

Product introduction

FB-WFPL/WFPM Chain Plate weigh feeder is a new generation of equipment based on the FB-WFM/L belt weigh feeder for proportioning process. It is used for weighing and dosing the material with abrasiveness, high moisture, high pressure or high temperature, such as limestone, shale, iron stone which is easy to wear belt, high moisture clay, iron powder and high temperature clinker, hydrated lime etc. It can solve the problems such as poor carrying capacity, conveying difficulty, belt slipping for heavy load and save a lot cost for changing belt frequently. FB-WFPL/WFPM Chain Plate weigh feeder can be applied for building material industry, power, chemical and steel industry etc.

Highlight Features


Using high quality steel, once - molded.

Weighing Device

Load directly acts on load cells through multi rollers and double sensors reduce error during force transmission. So that to improve the weighing accuracy and become more reliable.

Drive Device

Hollow shaft connects with the head pulley directly, easy to assembly and disassembly. Speed can be adjusted, running stably and reliably without noisy. Heat radiator can be chosen when it runs in low speed.

Head and Tail Pulley

The pulleys are held by self-aligning ball bearing, the active pulley is covered by rubber in case of overload slipping. The passive pulley is easy to tighten.

Automatic Tighten Device and Anti-deviation Device

Keep the chain plate tension constantly and moderately. During running, it can adjust the chain plate automatically in case of belt deviation affecting the weighing accuracy.

Inner and Outer Sweeping Device

Wear-resistant roller brush can sweep the residual on the chain plate effectively, keeping the measurement parameters stable and improving the accuracy. Inner sweeper cleans the passive pulley, inclusion and residual material on the inner surface of belt, which prolong the service life.

Conveying Belt and Chain

The thickened and multilayer rubbers are chose as conveying belt, and wear-resistant steel plate as chain plate. The thickness of steel plate is 3mm to 5mm, shaped by one time. Chain plate links with hasps, which makes the friction larger between the material and chain plate, so as to convey the material evenly.

Material Hopper

Big opening designed to avoid material discharging sluggishly. Thickened and wear-resistant liner can be chosen. And valves or pre-feeding equipment and other non-standard equipment can be customized according to the material characteristics and the process requirements.
