Second hand crushers refer to crushing equipment that enters the market again after use, usually including hammer, jaw, impact, and other types. This type of equipment is widely used in industries such as chemical, food processing, and pharmaceuticals, mainly for crushing solid materials into smaller particles or powders. When purchasing a second-hand crusher, it is important to pay close attention to key indicators such as equipment wear and tear, maintenance history, and production capacity.

Technical principle: The crusher decomposes materials through mechanical forces such as impact, shearing, and grinding. The wear of core components of second-hand equipment, such as rotors, screens, and bearings, directly affects efficiency and finished product quality. For example, when the wear of the hammer head of a hammer mill exceeds 5mm, the production capacity may decrease by 20% -30%.

Application scenarios:

1. Food industry: When processing starch and sugar, stainless steel material should be selected (to avoid contamination), and the fineness is usually required to be between 200-500 mesh.

2. Chemical industry: Corrosion resistant models are more suitable for handling acidic and alkaline materials. It is recommended to check the thickness of the lining plate (with a remaining thickness of ≥ 8mm).

3. Renewable resources: When crushing plastic or metal, it is necessary to confirm whether the motor power matches (usually 7.5-55kW).

Precautions for purchasing:

• Performance verification: Test the bearing temperature (should be<70 ℃) and noise level (≤ 85dB is normal) during no-load operation.

• Loss assessment: If the deformation rate of the sieve aperture is greater than 15%, it needs to be replaced, and if the wear of the tool edge is greater than 3mm, it will affect the crushing efficiency.

• Compliance: Check whether the equipment has passed CE or GB certification, especially explosion-proof requirements (such as when handling flammable dust).

Maintenance suggestion:

1. Lubricate the bearings every 50 working hours using ISO VG68 grade grease.

2. Regularly calibrate the dynamic balance (allowing residual unbalance ≤ 2.5g · mm/kg).

3. It is recommended to use original accessories when replacing vulnerable parts (such as controlling the gap tolerance of the screen mesh within ± 0.1mm).

Large scale processing of second-hand crusher equipment for long-term sale and transferThe current second-hand market price range is relatively large, with ordinary hammer crushers costing around 8000-30000 yuan, while ultrafine crusher models may reach 50000-150000 yuan, depending on the model, service life, and technical status. It is recommended to evaluate key indicators through a third-party testing agency before making a decision. Now there is a horizontal ultrafine grinder in the store, made of stainless steel material, with integrated crushing, grinding and grading functions, excellent particle size uniformity, especially suitable for processing starch materials, with a fineness of up to 200-1000 mesh.
