Molecular Sieve Production Line

Molecular sieve production line

Molecular sieve is a silico-aluminate compound with a cubic lattice. Molecular sieve has a uniform micropore structure, its hole diameter is uniform, these holes can adsorb molecules smaller than its diameter to the interior of the cavity, and has a preferential adsorption capacity for polar molecules and unsaturated molecules, so it can separate molecules with different degrees of polarity, different degrees of saturation, different molecular sizes and different boiling points, that is, it has the role of "screening" molecules. So called molecular sieve.

Main equipment: cylinder granulator, dryer, external heat rotary kiln

Application: It can be used as desiccant, selective adsorbent, catalyst, ion exchanger, etc., in chemical industry, metallurgy, building materials, mining and other industries.

Outstanding advantage

High degree of automation: to avoid the influence of artificial factors on the quality of molecular sieve products, the product quality is excellent, the quality of all particle products is basically the same, to avoid the phenomenon of incomplete.

Good site environment: The granulator adopts automatic powder adding during the ball forming process, and sets the dust removal port to prevent dust spillover, and the site working conditions are good.

High yield: the resulting molecular sieve semi-finished ball scrap rate is low.

High control accuracy: powder and water are measured accurately, and the measurement accuracy is within ±1% to ensure product quality.

Process flow

It mainly consists of the following processes:

Mixing: Several raw materials for the production of molecular sieve are sent to the screw belt mixer according to the set ratio to mix evenly, and then sent to the storage bin through the screw conveyor and bucket elevator.

Granulation: The spiral weighing scale set under the storage bin measures the material into the fabric screw feed port of the granulator through the bucket elevator, and the set water is added to the granulator through the water metering device, and the material and water contact to form the material ball. The granulator is equipped with a scraper and rake device to prevent the material from sticking to the inner wall, and the rake can effectively prevent the material from forming into a group. Part of the material after the pelletizer molding is sent to the two-stage vibrating screen for screening, and part of the material is returned to the pelletizer through the return belt machine and the bucket elevator.

Hardening: The qualified material is hardened through the hardening cylinder, so that the surface of the material is more rounded, and the quality of the finished product is better.

Drying: Through the mesh dryer to dry the material after shaping, mesh drying belongs to static drying, can reduce the crushing of the material ball.

Calcination: The material ball after drying is calcined by the external heat rotary kiln. The external heat rotary kiln avoids direct contact between the material and the hot gas, which can reduce the pollution of the material.

Screening and packaging: The calcined material is sifted through the rotary vibrating screen and sent to the finished product warehouse. There is a packaging machine under the warehouse, and the material can be packed into the appropriate specifications through the packaging machine.
