Rice Lake Weighing Systems products

The 221DB Master belt scale weigh frame consists of two arms equipped with a pivot and a load cell mounted to the side supports of the conveyor belt. The idler, or weighing roller, is mounted on top of the frame arms. The 221DB provides simple assembly and accessibility for service. Suitable for most belt widths and capacities, the 221DB is a versatile solution for many applications.

Consisting of an idler or weighing roller placed on a simple load cell beam, the 311M Master belt scale weigh frame is a cost-effective solution. Suitable for belt widths up to 1.500 mm and belt speeds up to 2 meters per second, the BS311 frame is often used for belts that can regulate the capacity of a bulk flow using the measured value and a controlled belt speed.

The 211 Master belt scale weigh frame 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. The friction-free pivots absorb tensile stress in a horizontal direction, creating a very solid weigh frame well-suited for heavy-duty applications.

Weigh three idlers on an inner frame, supported by four load cells with the 14x Master belt scale weigh frame. This creates an incredibly accurate belt scale qualified for high capacities and belt speeds. The 14x is often used in mining and aggregate applications. The frame is custom-made using the specifications of the conveyor belt, making it suitable for different belt conveyor models.

The 421 Master belt scale weigh frame is specifically designed for high volume, low-density applications where belt load and belt speed are moderate. Ideal for flat belt conveyors, the 421 features two BM11 bending beams and hermetically sealed load cells mounted to adjusting plates on the outside of the conveyor stringers to create a stable base. The 421 master belt scale is also available for hazardous and explosive areas.

Belt scales used in demanding industries like mining, bulk material blending, and sand or gravel quarries require instrumentation that can keep up. The tough yet compact 882D belt scale integrator is engineered to provide straightforward, accurate data in a wide range of environments — even hazardous locations. Designed with advanced programming capabilities and an I/O option, the 882D can be customized to manage product dosing and metering.

Industrial design with modular hardware ideal choice for the listed applications:

The speed sensor monitors belt speed. It is directly coupled to a rotating shaft which drives a signal generator. The speed sensor submits an output signal at a frequency directly proportional to the shaft speed. It is typically installed on a non-driven pulley of a belt conveyor for detecting belt speed.

Rigid speed sensing device for dynamic weighing. Features direct coupling to the conveyor tail pulley. No wheels ride on the belt.

Reliable mounting in wide variety of installation situations. Standard encoder for use worldwide. Sturdy (Safety-lock™) design bearing structure. Resistant die-cast housing.
