Hubei Machine-Made Sand Project Case

Publish Time: 2025-04-21

Ⅰ、Project name: Hubei XXX Building Materials Co., Ltd. 's annual production line of 2 million tons of high-quality machine-made sand

Raw material type: basalt (compressive strength 210MPa)

Project Features:

- Newly constructed fixed machine-made sand production line

- Requires long equipment life, excellent particle shape, and stable operation

Ⅱ. Core Advantages Implementation Plan

1. Ultra-long equipment life design**

Equipment parts	Technological innovation	Service life	Industry average
Sand making machine wear parts	Tungsten carbide composite welding technology	2000 hours	1000 hours
Cone crusher lining	High chromium cast iron + special heat treatment process	10 months	6 months
Screen	Manganese wire + steel wire composite structure	8 months	4 months

Measured data:

- Continuous operation for 10 months without replacing the core wear parts

- Equipment failure rate < 0.5% (industry average 3%)

2. Fine grain shape control system

Three-stage plastic surgery process:

1). **Cone crusher pre-shaping**: laminated crushing to reduce needle-like

2). ** Impact crusher shaping**: Stone-on-stone mode cube ratio > 92%

3). Linear screening: precise control of 0-4.75mm grading , single screening over 800 tons

Finished sand quality:

index	National Standards	Data of this project
Fineness modulus	2.3-3.0	2.7 ± 0.1
Stone powder content	5-10%	7.50%
Crushing indicators	≤ 25%	18%
Bulk density	≥ 1400kg/ m³	1520kg/ m³

Ⅲ. Production Line Configuration

Main equipment:

1. Primary crushing: JC series jaw crusher

2. Medium crushing and shaping: HPT multi-cylinder hydraulic cone crusher

3. Sand making and shaping: VSI6X 1150 impact crusher

4. Screening system: 3YKZ3070 multi-layer vibrating screen

Intelligent control system:

- Online particle shape monitoring system

- Automatic adjustment of crushing chamber parameters

- Remote fault diagnosis

IV. Project Benefits

Economic benefits:

- 35% reduction in production cost per ton

- Product premium 20-30 yuan/ton

- Annual efficiency increase exceeds RMB 3 million

Environmental benefits:

- Dust emission <10mg/m³

- Wastewater recycling rate 100%

- Noise＜65dB

Customer reviews:

"What satisfies us most about this production line is that the equipment requires almost no maintenance and the sand grain shape is particularly good. It has now become a model project for the sand making plant nearby ."
