Rockwell Industrial Plants Limited

USEOverview of Functional RequirementA closed system shredder designed for shredding of recyclable plastic hospital where the final treated waste should be non- reusable & non recognizable and should be reduced to 70 to 80% of the volume.

Standards and SafetyQuality Standard relating toProducta) Product should be CE or BIS approved product.b) Cutter motor should be ISI marked.c) Should be CPCB approved with compliance under Gazette Notification 1998 and revisions there upon.ManufacturerShould be ISO 9001 certified for quality standards.

Electrical SafetyShould conform to the standards for electrical safety as per BIS.Test certificatesTest certificates from Govt. approved laboratory or NABL approved laboratory for Steel grade certificate should be furnished in the technical bid.

Technical requirements, desirable characteristics:1. Should be of robust design with minimum maintenance requirement.2. Should be properly designed and covered to avoid spillage and dust generation. It should be designed such that it has minimum manual handling.3. The hopper and cutting chamber of the shredder should be so designed to accommodate the waste bag full of biomedical waste.4. The shredder blade should be highly resistant and should be able to handle/ shred wet waste, especially after microwave/ autoclave/ hydroclave.5. The motor should be connected to the shredder shaft through a gear mechanism, to ensure low rpm and safety for better gripping and cutting of the biomedical waste.6. Should have induction motor and the minimum capacity of the motor attached with the shredder should be adequate enough for carrying out for 25 Kg/hr. This would ensure efficient cutting of the bio-medical waste as prescribed in the bio- medical waste (Management & handling) Rules.7. Should be provided with sliding System to avoid spreading of waste during removal of collection trolley

a) Capacity of Shredder: 25 Kg/Hrb) Type: Low Speed / Low RPM (preferably 30 to 40 rpm)c) Material of Construction of Outer Body: Mild Steel (M.S), 5 mm Thicknessd) Material of Construction of Cutter : Non-Corrosive & hardened Alloy Steele)Waste Feeding Platform: MS Structure having minimum 3 feet height from discharge point to ground level.f) Waste Feeding System : Manual Through Hopperg) Electric Load: 3 KW or less with at least 4HP induction motorh) Shaft : Double Shafti) Drive : Belt or Gear Drive

Control Panela)                Should be Pre-Wired and Powder Coated.

Should be provided with auto stop/reversing, Emergency stop & Limit Switch with audio and/or visual alarm or indicator for the stoppage.

Safety Features to operate this type of deviceOperational Safetiesa) Interlocking with Limit Switchb) Shock proof & insulated as per safety norms.c) Protection against scattering of shredded wasteSafeties for Overloadinga) Reverse Motion to avoid overloading or jamming mechanismb) Motor overload protection.

Automatic emergency stopa) Limit switch should be provided to switch off the Shredder if hopper lid or door of collection box is opened, so that shredder should stop automatically for safety of operator.b) In case of shock-loading (non-shred able material in the hopper), there should be a mechanism to automatically stop the shredder to avoid any emergency/ accident.General Safetya) The unit should be suitably designed for operator safety, mechanical as well as electrical.b) Anti-vibration mounting should be provided.Physical CharacteristicsNoise (in dBA) & VibrationLow Noise (below 60 dB) and No VibrationHeat dissipationShould maintain nominal Temp & heat should be disbursed by a cooling mechanism.Mobility, portability Stationary Installation TypeEnergy Source (electricity, UPS, solar, gas, water etc.)Power requirementPower Input voltage- 220V AC, 50Hz, single-phase fitted with Indian plug of appropriate rating.
