Particle Size Reduction Machines Karl Bryan Ren C. Barbarona BSSE 5

Five different types of size reduction equipment, its application and mode of action

EDGE RUNNER MILL

CUTTER MILL

Impact Crusher Impact size reduction incorporates striking to pulverize material. The primary types of impact crushers include -- horizontal shaft impactors (HSI), cage mill pulverizers, and vertical shaft impactors(VSI).

Uses of Impact Crusher Aggregate- Cement, Concrete, etc.  Coal, Energy & Biomass  Minerals & Mining Brick, Clay & Ceramics Industrial Applications and many more…

ROLLER MILL: Material is crushed by the application of stress. Stress is applied by rotating heavy wheels, mullers or rollers. USES: for crushing seeds before extraction of fixed oil. Also used to crush soft tissue to help in penetration of solvents.

Hammer mill Crusher that can grind, pulverize, and crush a wide range of materials. This rock crusher machine employs a rain of hammer blows to shatter and disintegrate the material. Hammer mills produce a finish product size that is dependent upon... Openings in perforated screens or grate bars. Number, size and type of hammers Grinding plate setting Rotor speed.

Hammer Mill Applications 1. Calcium Carbonate 2. Coal 3. Stone 4. Graphite 5. Salts MODE OF ACTION: Breaking Tearing Crushing Cutting

Fine Grinder The number and kind of grinding mills are as diverse as the materials they are designed to reduce. Fine grinder products include modern air swept material handling and classification methods to efficiently produce consistent finely ground powder products.

1. Agricultural Processing Fine grinders Uses 1. Agricultural Processing 2. Chemical Processing 3. Feed Processing 4. Food Processing 5. Mineral Processing 6. Pharmaceutical 7. Rendering 8. Soap & Detergent

Waste processing technique Resource recovery is the selective extraction of disposed materials for a specific next use, such as recycling, composting or energy generation in order to extract the maximum benefits from products, delay the consumption of virgin resources, and reduce the amount of waste generated. Resource recovery differs from the management of waste by using life-cycle analysis (LCA) to offer alternatives to landfill disposal of discarded materials. A number of studies on municipal solid waste (MSW) have indicated that administration, source separation and collection followed by reuse and recycling of the non-organic fraction and energy and compost/fertilizer production of the organic waste fraction via anaerobic digestion to be the favoured alternatives to landfilldisposal. Similarly, in the context of sanitation, the term "resource recovery" is used to denote sanitation systems that aim to recover and reuse the resources that are contained in wastewater and excreta (urine and feces). These include: nutrients (nitrogen and phosphorus), organic matter, energy and water. This concept is also referred to as ecological sanitation or productive sanitation.
