Small crusher is mainly used to further process the materials that have been initially crushed or granulated into fine powder. Coreal Machinery has compiled some information for your reference.
Core functions and features
Purpose: Finely crush to the required particle size (usually from tens of meshes to thousands of meshes).
Feeding requirements: The materials usually need to be processed into small particles (a few millimeters to about 1-2 cm) by the crusher in advance before they can be efficiently fed into the Small crusher for fine grinding.
Working principle: Mainly relying on grinding, rolling, impact, shearing and other forces. Small crushers with different principles are suitable for materials with different characteristics.
Discharge fineness: Fine and uniform. The fineness can be controlled by adjusting the grinding disc gap, screen mesh number, classifier speed, air flow speed and other parameters.
Widely used: Food, chemical, pharmaceutical, mining, building materials, agriculture, metallurgy, environmental protection and other industries.
(Small) Features:
Compact structure, small footprint, easy to move or fixed installation.
Relatively small power (ranging from hundreds of watts to tens of kilowatts).
The processing capacity is limited (from a few kilograms to hundreds of kilograms per hour).
Relatively simple to operate and easy to maintain.
The cost is much lower than that of large industrial Small crushers.
Key factors for choosing a small Small crusher
Material characteristics:
Hardness: Determines how much crushing force is required (hammer and disc are suitable for medium hardness, and airflow mill is suitable for high hardness or toughness).
Moisture content/oiliness: High moisture or oily materials are prone to adhesion and clogging (need to choose non-clogging such as airflow mill or screenless design, or pre-treatment drying).
Fiber/toughness: Materials with high fiber content or strong toughness (such as Chinese medicinal roots and plastics) require equipment with strong shear force or impact force (such as turbine airflow mill, hammer with toothed disc).
Heat sensitivity: Materials afraid of high temperature (such as medicinal materials, spices, plastics) need low temperature crushing (disc water cooling, airflow mill).
Flammability and explosion: Explosion-proof or inert gas protection equipment needs to be selected.
Target particle size: The finer the requirement, the more special the type of equipment may be (such as air flow mill, ball mill).
Output requirements: How many kilograms need to be processed per hour? This determines the model and power of the equipment.
Finished product fineness requirements: How many powders are needed? Different equipment can achieve different ultimate fineness and efficiency.
Hygiene requirements: Food and pharmaceutical applications must choose equipment that meets GMP/HACCP standards (usually all stainless steel, easy to clean structure).
Equipment material: The part that contacts the material needs to be selected according to the nature of the material (stainless steel 304/316, carbon steel, ceramic, etc.), and food and medicine must use stainless steel.
Consumable parts and maintenance: Understand the replacement frequency and cost of consumable parts such as hammers, grinding discs, screens, bearings, etc.
Dust removal requirements: The grinding process is usually accompanied by dust, and it is necessary to consider whether it has its own dust removal device or requires an external dust removal system.
Budget: The price of equipment of different types and configurations varies greatly.
