Vacuum feeder

Vacuum feeding machine, also known as vacuum conveyor, is a kind of dust-free closed pipeline conveying equipment for conveying particles and powdered materials by means of vacuum suction. The air pressure difference between vacuum and environmental space is used to form gas flow in the pipeline and drive the movement of powdered materials, thus completing the conveying of powder. Our company introduces advanced foreign vacuum technology, constantly improves and improves, and is now widely used in chemical, pharmaceutical, food, metallurgy, building materials, agricultural and other light and heavy industries. Vacuum conveying is a closed pipeline conveying. This conveying method can eliminate dust environmental pollution, improve the working environment, and reduce the pollution of the environment and personnel to materials, and improve

THFX stopcock reversing valve

THFX cock reversing valve (two-way valve) is a device for switching materials in pneumatic conveying system. It enables the material in the pipeline to change the conveying direction in the flow state without interrupting the supply and stopping the gas supply, and sends the material to two selected locations. If the combination of several valves can be sent to many selected locations, so the operation is very convenient. It is widely used in flour, bran, starch, feed, sugar, chemical products and other powder materials positive and negative pressure conveying and low speed conveying pipe road to change the conveying direction, so that the material is sent to the selected location.

BFCP BFCZ type positive pressure off fan

BFCP/BFEZ type wind shutter is the feeding equipment of pneumatic conveying system. It has the characteristics of continuous or intermittent forced feeding of materials into the conveying pipe under positive pressure by air flow: it can be used as a feeder for positive pressure conveying system of flour, bran, starch, grain, feed, sugar, chemical products and plastic powder materials. Materials with high adhesion are not suitable for use. BFCP is side-to-side communication: channels are provided at the lower part of the bearing seats on the left and right sides to connect with the conveying pipes, U-shaped axial discharge grooves are provided at the lower part of the casing, materials can only go from the side, BFCZ is vertical communication: there are no channels at the bearing seats on the left and right sides, and the discharge ports at the lower part of the casing and
