SECTION-BTECHNICAL

SPECIFICATIONS:MECHANICAL SYSTEMS

1. Process descriptionAmmonium perchlorate (AP) is used as oxidizer in propellant. AP is explosive and hygroscopic. AP is received from source in Flexible Intermediate Bulk Container(FIBC) in the multiples of 1 ton. AP received from source is referred as AP coarse (APC). APC undergoes size reduction using hammer mill. Ground AP is referred as AP fine(APF). AP received from AP storage is lifted to feeding room and discharged into a feed hopper of capacity 3000 kg. Hopper consists of a pneumatically operated 300 mm Knife edged gate valve(KGV) or suitable valve. The feed hopper realization is in the scope of department(purchaser). The interface is 300 mm flange of the KGV for further downstream works. The output from KGV will be 2000 kg/hr nominal. Further delivery of the material into the hammer mill shall be designed by the supplier. The supplier is expected to give the design for the feed system.Similarly, the output of hammer mill shall be collected a collection hopper (it is expected that the collection mechanism will be through gravity assisted reverse pulse jet dust collection/pulsaire system with negative suction created by blower). The supplier is expected to give design for ground material conveying and collection system that includes blowers, ducting, pulsaire unit, interfaces to collection hopper. The collection hopper realization is in the scope of department(purchaser). The collection hopper dimensions are ~2.1 x 2.4 x 3.0 m, it is planned to have top opening of Φ300 mm with a flange for interfacing with the dust collection/pulsaire system. The legs of the pulsaire under which this collection hopper is placed shall be properly designed for horizontal travel of the collection hopper positioned on trolley. Approximate height of the trolley is maximum 1 m. Proper design of pulsaire dimensions are also important because the hammer mill is located at an elevation of 8.5 m from finished floor level and may be away from pulsaire location by ~4.5 m. The angle of inclination of the duct from horizontal shall be minimum 10⁰ downwards for gravity assisted flow.Further details are given in the following table a. Feeding systemb. Grinding systemc. Fine collection system 1. Feeding system Description

a. Feed hopper Input material Ammonium Perchlorate Coarse will be loaded into the feed hopper. The capacity of feed hopper is 3000 kg. This hopper will be provided with a knife edge gate valve.(this is in the scope of purchaser)

b.

Dosing screw feeder

This screw feeder will be used to feed material with a constant feed rate to intermediate hopper.

c. Intermediate hopper

Material from dosing screw feeder is fed into intermediate hopper at constant feed rate.

Intermediate hopper consists of a mesh, to prevent the entry of foreign material into grinding system.

An independent bar magnet will be positioned above the mesh to prevent the entry of metal particles into grinding system.

d. Stuffing screw feeder

Material from intermediate hopper will be drawn and fed to hammer mill at a constant feed rate by stuffing

26

screw feeder.

2. Grinding system

a. Hammer mill Material fed to hammer mill will be ground by the hammer which will rotate at a desired RPM in order to reduce particle size of material to a desired size referred as AP fine(APF).

3. Collection system

a. Blower APF will be conveyed from hammer mill to the collection point pneumatically.

Suction is provided by blower by proper ducting and interfacing between blower and hammer mill.

b. Dust collection system/pulsaire unit

During pneumatic conveying the material passes through a dust collection system.

Dust collection system consists of filter bag units and pulsing unit.

APF and air will be separated at the surface of filter bags and material will be collected at the bottom of dust collection system into a collection hopper.

In order to dislodge APF stuck to the surface of filter bags, a reverse jet of dried compressed air is injected into the dust collection system using solenoids and sequential timer unit.

Thus, the material will be collected and treated as output of grinding process.

As the material being handled is explosive and hazardous in nature, the process operations are carried out with utmost care and process, safety interlocks. Total process is treated as an unmanned operation. No personnel is allowed into the process building during process operations. Total system will be controlled from control room located at ~100 m away from process area remotely.The following table describes the interlocks required from department point of view and are essential. However, the supplier has to study and design the interlocks required for the system proposed by him and shall ensure that the interlocks suggested by purchaser are also incorporated. This shall form a part of the design document.
