Cobble Stone Crushing Solutions

Cobble stone crushing and sand making equipment programme needs to be configured in combination with the high hardness and wear resistance of cobblestone and the production demand output and finished product specifications. As a kind of natural stone, pebbles are widely used in construction, gardening, decoration, water conservancy and other fields because of its high hardness, wear resistance, beautiful appearance and other characteristics. In order to process pebbles into finished sand and gravel aggregate that meets the market demand, it is crucial to configure a complete set of processing and crushing equipment.

Detailed Analysis Of Pebble Crushing Sand Making Programme:

The Core Process

Cobble Stone crushing sand making process is usually divided into coarse crushing → medium crushing → fine crushing and shaping → screening → cleaning of five stages:

Coarse Crushing Stage

Equipment: Jaw Crusher (preferred)

Jaw Crusher

Jaw Crusher

Function: Crushing the large pebbles (feed size 120-1500mm) to a medium size of 100-300mm.
Recommended model: PE series jaw crusher, capacity 1-2200 tonnes / hour, high crushing ratio and stable operation.

Medium Crushing Stage

Equipment: Impact Crusher (for low and medium hardness)

Impact Crusher

Impact Crusher

Function: further crush the roughly crushed materials to 30-100mm.
Recommended model: Hydraulic Cone Crusher with adjustable discharge opening, Impact Crusher with strong impact force and low maintenance cost.

Fine Crushing and Shaping Stage

Equipment: Roller Sand Maker

Roller Sand Maker

Roller Sand Maker

Function: To crush the material to 0-5mm. Roller Sand Maker can precisely adjust the gap between two rollers (1mm~20mm) to realise the full size coverage from coarse crushing to fine grinding, and the finished sand has even grain shape and low powder content.

Screening and Classification

Equipment: Multi-layer Vibrating Screen

Multi-layer Vibrating Screen

Multi-layer Vibrating Screen

Function: Screening out the sand that meets the specification, and the materials that do not meet the standard return to the sand making machine for recycling.

Cleaning and Dewatering

Equipment: Bucket Washer + Dewatering Screen + Fine Sand Recycling Machine
Function: Remove impurities, reduce mud content, and improve the quality of finished products; Fine Sand Recycling Machine reduces the waste of resources.

Equipment Configuration Programme

Cobble Stone Crushing  According To The Production Scale And Site Conditions, The Following Programme Can Be Selected:

Core equipment: Jaw Crusher + Impact Crusher + Roller Sand Making Machine + Vibrating Screen + Sand Washing Machine.
Auxiliary equipment: vibrating feeder, belt conveyor, silo, dust removal system. Advantages:

Large processing capacity (hourly output can be up to 2000 tonnes or more), suitable for large-scale production. Low energy consumption, easy maintenance, long equipment life.
Disadvantages: need fixed site and concrete foundation, high transfer cost.

Suggestions for equipment purchase

Matching according to the production demand:

Processing capacity: choose the equipment model according to the output (e.g. 200 tonnes per hour needs to be configured with HPT300+VSI6X1040 combination).
Finished product specifications: adjust the screen level and sand making machine parameters to control the particle size (such as 0-5mm, 5-10mm, etc.).

Focus on equipment performance:

Wear-resistant material: Prefer equipment with high chrome alloy liner and extra hard alloy cutter head. Energy consumption and environmental protection: hydraulic drive, closed structure can reduce energy consumption and dust.
Maintenance and after-sales service:

Simple structure and few wearing parts (e.g. hydraulic adjustment system of cone breaker) can reduce maintenance cost. Choose manufacturers that provide customised solutions and long-term technical support.

Cost and Benefit Analysis

Fixed production line: the initial investment is about several hundred thousand to one million, suitable for long-term stable production. Mobile production line: the initial investment is higher (millions), but saves infrastructure and transport costs. Payback cycle: according to the market price of sand and gravel, usually 1-3 years can pay back.

The above solutions can meet the needs of different scenarios, and it is recommended to choose them in combination with site conditions, budget and finished product requirements.
