What is a copper granulator?
Copper cable granulator, also named scrap wire recycling equipment , is a machine used for crushing copper scrap and later separating copper from the plastic. It belongs to environmental protection equipment. The Classification of Copper Cable Granulator.
How does a copper wire granulator work?
Wire granulators take scrap copper wire and separate the copper from the plastic that insulates the wire. The machine uses a dry physical crushing method. This prevents pollution while making the extraction process as simple as possible.
What is a cable granulator?
Home/Cable granulators. Our range of Matrix Cable granulators shred, separate and recover copper and aluminium from domestic and industrial insulated wires and cables. They can also handle car looms with an optional unit that injects powder to dry the grease.
How does a granulator work?
A drum granulator works by tumbling material in the presence of a liquid binder to encourage granule formation and growth. Feed material and binder are constantly fed through the rotating drum. The rolling action, combined with the stickiness from the binder, causes fines to collect together into particles.
How many types of granulation are there?
Granulation process can be divided into two types: wet granulation that utilize a liquid in the process and dry granulation that requires no liquid. The type of process selection requires thorough knowledge of physicochemical properties of the drug, excipients, required flow and release properties, to name a few.
Why granulation is required?
Why is Granulation Necessary? The granulation process allows particles to stick together more firmly. It increases the particle size of the constituents used, which are mostly very fine powders. The greater the particle size of a constituent, greater will be its compressive or binding ability.
What are problems of granulation?
Nevertheless, granulation poses numerous challenges due to high quality requirement of the formed granules in terms of content uniformity and physicochemical properties such as granule size, bulk density, porosity, hardness, moisture, compressibility, etc. together with physical and chemical stability of the drug.
What is RMG principle?
The principle of Working:
In rapid mixer granulator, the formation of granules occurs by rising, whirling and tumbling motion of the material. Dry mixing is done by adding all ingredients into the RMG by rotation of impeller and chopper at high speed.
What are the steps of granulation?
Steps in wet granulation method of tablet production
- Step 1: Weighing and mixing of formulation ingredients (excluding the lubricant).
- Step 2: Preparing the damp mass.
- Step 3: Wet screening/ Screening the dampened powder into pellets or granules.
- Step 4: Drying of moist granules.
Which is better dry or wet granulation?
Importance. Dry Granulation: Dry granulation is required when producing tablets from highly moisture and heat sensitive compounds. Wet Granulation: Wet granulation is required to avoid the destruction of active components in the powder.
Why is FBD capacity in KG?
Why FBD (Fluidized Bed Dryer) capacity measured in Kg and RMG (Rapid Mixer Dryer) capacity measured in Litre? It’s a design issue. The main functionality of RMG is “holding, mixing and granulating of standard volume”. The bulk density is product specific and may not be same for all products.
How is RMG capacity calculated?
Claimed capacity is provided by vendor in liters and to calculate capacity in kgs,first calculate bulk density of powder to be mixed and then it is multiplied by capacity in liters. claimed capaciy in liters is 400 liter and bulk density is 0.8 then capacity in kgs is 400*0.8=320kg.
How is FBD calculated?
Flow rate = Velocity x Area of cross section. Total capacity required = 884 / 0.8 = 1105 m3/hr = 651 CFM.
What is RMG end point?
Endpoint can be defined as a target particle size mean or distribution. Traditional Methods. a) Power Consumption.
Why is RMG capacity in KG?
Working capacity in a liter is 600 liter, and its working volume is 80% means 480 liters and bulk density is 0.5; then capacity in kgs is 480X0. 5= 240 kg. so we can make a batch of 240 kg materials in modal of 600 liters RMG.
Why is RMG measured in liters?
The bulk density is product specific and may not be same for all products. You product may be cotton (lowest density) or osmium (highest density), you can process only the standard volume in your RMG. Hence its capacity is mentioned in liters.
What is torque in RMG?
The magnitude of this torque is rmg sin θ, where θ is the angle between r and F. For the mass hangers, when the meter stick is horizontal, θ equals 90 degrees, sin θ equals 1, and τ = rmg. Torque, especially in this context, is often called the moment of force, and r is the moment arm.
