Working PrincipleHP belt type constant speed quantitative feeder when the measured weight in the silo reaches the lower limit position of the weighing hopper, the discharging screw machine or other actuators will fix the discharging amount according to the rotating speed at that time, and control the materials in the silo to go down to the weighing hopper quickly (manually or automatically), stop loading when the material is loaded to the upper limit of the weighing, the quick loading can shorten the time of feeding, and the system will restore the loss-in-weight measurement mode automatically, this mode can improve the accuracy of weighing more. The system automatically resumes the loss-in-weight weighing mode, which improves the weighing accuracy and control precision. In batch weighing loss-in-weight systems, the design is similar to that of continuous loss-in-weight systems, however, the accuracy of the final weight of the feeding (batch) cycle is higher than that of the actual feed volume control.
The electromagnetic vibrating feeder used in the HP Belt Constant Velocity Quantitative Feeder is a device that conveys materials under the action of a directional electromagnetic force. This equipment has harnessed power is small, there is no large starting current, does not cause network voltage drop, amplitude instantaneous can reach a stable value, you can immediately stop and run and so on, and also can be smooth stepless adjustment of the feeding volume, to achieve automatic control. However, the current domestic production of electromagnetic vibrating feeder, there are large size, voice, control part of the complexity of the price and other shortcomings.GZ series of electromagnetic vibrating feeder is used to block, granular and powdery materials, from the storage silo or hopper in a uniform and continuous or quantitative feeding to the receiving device, can be infinitely adjustable feeding volume, and to achieve the centralized control of the production process and automatic control. It is small in size, light in weight, easy to install, no rotating parts, no lubrication, easy to maintain, high working frequency, and consumes less electric energy. It is widely used in mining, metallurgy, coal, chemical industry, electric power, machinery, food and other industries. The maximum output of 1000T per hour is divided into sealed type and open type. On the basis of absorbing advanced technology at home and abroad, our company has recently designed a new type of GZ electromagnetic vibrating feeder, whose structure is shown in the figure.
