Jiangxi Mingxin Metallurgical Equipment Co., Ltd. is a high-tech enterprise specializing in the research and development of mining machinery and environmental protection equipment. Its crusher products have a wide range of applications in mineral processing, solid waste treatment, and other fields. Based on the physical properties of barite (hardness 3-3.5, density 4.0-4.6g/cm ³) and industry demand, the following analysis is conducted from the aspects of equipment adaptability, technical characteristics, application scenarios, and selection suggestions:

1、 Technical characteristics and adaptability of Jiangxi Mingxin crusher

1. Core equipment type

Jiangxi Mingxin's crusher product line covers mainstream models such as jaw crushers, hammer crushers, and roll crushers, among which the following equipment has good adaptability for heavy spar processing:

Jaw crusher: suitable for coarse crushing, with a maximum feed particle size of up to 600mm, and achieves preliminary processing through extrusion crushing. Its deep cavity design and high manganese steel jaw plate can effectively cope with the high-density characteristics of barite and reduce the risk of blockage.

Hammer crusher: Adopting a dual rotor or single-stage hammer structure, it can achieve the integration of medium and fine crushing, with a discharge particle size of ≤ 30mm. The design without a screen bottom is particularly suitable for wet barite (moisture content ≤ 15%), avoiding the problem of traditional screen clogging.

Roller crusher: By adjusting the gap between the rollers through hydraulic pressure, it can produce fine products of 0-5mm, suitable for pre-treatment before grinding heavy spar. The principle of laminated crushing can reduce the over crushing rate and improve the subsequent flotation efficiency.

2. Key technological advantages

Application of wear-resistant materials: The crusher hammer head and lining plate are made of high chromium alloy or high manganese steel material, which extends the service life of heavy spar crushing by more than 30% compared to traditional materials. For example, the alloy hammer head of a hammer crusher can have a single replacement cycle of over 800 hours when processing heavy crystals with a hardness of 3-3.5.

Environmental design: Fully enclosed crushing chamber combined with pulse dust removal system, dust emission ≤ 10mg/m ³, in compliance with the Comprehensive Emission Standards for Air Pollutants. At the same time, the operating noise of the equipment is below 85dB, meeting the environmental protection requirements of the mine.

Intelligent control: Some models are equipped with PLC intelligent modules, which can monitor parameters such as oil temperature and current in real time, automatically warn of faults and adjust operating modes, reducing manual maintenance costs.

2、 Process and Equipment Configuration Plan for Barite Crushing

1. Typical process route

Two stage closed loop process:

Coarse crushing: PE400 × 600 jaw crusher (processing capacity 40-100t/h) reduces the particle size of raw ore from ≤ 600mm to ≤ 150mm.

Intermediate crushing: PCZ1615 heavy hammer crusher (processing capacity 380-550t/h), further crushing to ≤ 30mm.

Screening: 3YKZ3070 circular vibrating screen (sieve hole 30mm), the material on the screen returns to intermediate crushing, achieving closed-loop control of particle size.

Refined processing flow:

Rough crushing: PE600 × 750 jaw crusher (processing capacity 80-240t/h).

Intermediate crushing: HPT300 cone crusher (processing capacity 120-350t/h) optimizes particle shape through laminated crushing.

Fine crushing: 2PG610 × 400 roller crusher (processing capacity 5-20t/h), producing -5mm ultrafine powder.

2. Application scenarios of Jiangxi Mingxin equipment

Mining: Suitable for large-scale production in major barite producing areas such as Tianzhu in Guizhou and Xiangzhou in Guangxi, it can replace imported equipment to achieve efficient crushing.

Mineral processing pretreatment: Reduce the ore particle size to -200 mesh before flotation, accounting for more than 60%, increase the contact area between reagents and minerals, and improve the concentrate grade by 5% -8%.

Solid waste recycling: Processing heavy crystal tailings or industrial waste, achieving resource reuse through crushing and screening, reducing tailings pond land occupation and environmental pollution.

3、 Selection suggestions and customer cases

1. Key parameters for selection

Production scale: Recommended combination of jaw crusher and hammer crusher for small mines (<100t/h); Medium sized mines (100-500t/h) can adopt a closed-loop system consisting of jaw crushers, cone crushers, and vibrating screens.

Product particle size: Barite for drilling mud requires -200 mesh, accounting for over 90%. It is recommended to add a ball mill for ultrafine grinding; Aggregates for building materials can be directly produced in the 0-10mm particle size range through a roller crusher.

Energy consumption cost: The new hydraulic cone crusher saves 25% electricity compared to traditional spring cone crushers, and can reduce annual operating costs by more than 150000 yuan (taking a 500t/h production line as an example).

2. Customer Case Reference

A certain heavy spar mine in Jiangxi Province: using Jiangxi Mingxin PE600 × 750 jaw crusher (processing capacity of 80-240t/h) and PCZ1308 hammer crusher (processing capacity of 100-200t/h), combined with 3YK1860 vibrating screen, the power consumption per ton of ore was reduced to 12kWh, and the product particle size qualification rate reached 98%.

A beneficiation plant in Guangxi has introduced Jiangxi Mingxin 2PG400 × 400 roller crusher (with a processing capacity of 5-12 t/h) before heavy spar flotation, which has increased the grinding fineness from -200 mesh to 50% to 70%, increased the flotation recovery rate by 6%, and achieved an annual efficiency increase of over 2 million yuan.
