How to eliminate blocked chute woes

September 2019 Maintenance, Test & Measurement, Calibration

The original electromechanical point level switch, Bin-Dicator diaphragm-type level controls were the first to enjoy general usage in the industry. Bin-Dicator eliminates bin overflow, empty bins, clogged conveyors, choked elevators and resulting damage and waste.

The Bin-Dicator control is a pressure actuated switch for use with free flowing bulk materials at atmospheric pressures. Actuation of the switch is the result of pressure exerted by the bulk material against the diaphragm assembly. De-actuation or switch release is a result of the bulk material clearing away from the diaphragm. The sensitivity of the diaphragm is adjustable to cater for different bulk materials. The switch offers a SPDT switch rated at 15 A at 430 VAC.

The simple and rugged construction of the cast aluminium enclosure, offering IP65 protection, can be mounted either inside or outside the bin. Outside the bin option allows for retro-fitting, lowering installation costs. The unassuming operating mechanism makes the entire unit readily accessible for inspection, resulting in lower maintenance costs. Many variations of the diaphragm are available for use in a wide range of dry materials and conditions of temperature, corrosion and moisture.

The Bin-Flo aerator is a simple and efficient means of introducing low pressure air into any dry finely ground material. The air is equally distributed in controlled quantities to give the material the ability to flow by gravity from bins, hoppers or chutes. Bin-Flo aerators incorporate non-clogging diffusers, an integral orifice and construction features which assure maintenance-free life. The Bin-Flo body is available in two different sizes and manufactured either in zinc plated steel or stainless steel.

The Bin-Flo aerator offers simple installation and can be installed from inside or outside the bin. The outside the bin option allows for retro-fitting and product inspection. The unique integral orifice controls the air consumption at any recommended pressure. The best and usually the most economical air supply is from a positive displacement low pressure blower. A non-clogging diffuser provides equal distribution of air and will not clog even with the finest materials. Bin-Flo offers a cotton diffuser for applications up to 85°C and fiberglass diffuser for applications up to 320°C.
