Rice Lake Master BS211 Belt Scale System

Belt Scale Systems

We proudly supply the Rice Lake Master Series 211 precision belt scale system that consists of an inner frame mounted with two friction-free pivots to one end of the scale. The load cell is located on the opposite end with the idler mounted on the inner frame. Therefore, the friction-free pivots absorb tensile stress in a horizontal direction. This creates a very solid weigh frame that is well-suited for heavy-duty applications that you can trust.

The BS211 is designed to monitor feed to crushers, mills, screens and other processes as well as regulate product loadout with an accuracy up to ±0.5%.

Rice Lake Loss in Weight Feeders

Loss-In-Weight Feeders

Discover ideal dosing systems for a variety of applications with Rice Lake Master Weighing Systems, now proudly supplied by Minprovise. Loss-In-Weight Feeders are ideal dosing systems for bulk product, dry and liquid materials and even poorly flowing materials.

Loss-in-weight feeders consist of a hopper with a dosing unit—typically a screw or vibrating unit—placed on load cells monitoring the material output during dosing. The dosing-unit hopper can be refilled manually or automatically from a storage hopper without impacting the dosing rate or stopping production.

Dosing is typically measured in kilograms per hour and a digital controller adjusts the speed of the dosing unit to match the setpoint, ensuring consistent product flow. › products › loss-in-weight-f

Whether used in food or chemical production, high temperature or ATEX environments, Rice Lake Weighing Systems has a loss-in-weight feeder to meet your requirements. Talk to our Sales Team today.
