Are your picks always broken? Teach you how to distinguish quality reasons and working conditions in 3 minutes, allowing you to make the right choice and save money.

"The pick that was just replaced is worn out again!" "It breaks as soon as it is put on the machine !" Frequent failure of picks is common in coal mining sites,which not only reduces efficiency but also increases the cost of consumables. This article teaches you how to accurately distinguish wherther the picks are always bad due to unsuitable working conditions or pick quality problems.It also recommends the durable choice-the mining picks of Mailinmat Technology (Xiamen）Co,Ltd.

1.It is necessary to understand that the picks are always damaged due to two reasons：their own quality defects and unsuitable working conditions。

（1）Identify the quality at a glance: If the following signals apper,there is a high probability that the pick quality is not up to standard:

• Irregular failures in batches:The pick of the same batch are all worn out and broken early(such as chipping 1-2 hours after being put on the machine)regardless of the installation position,which is a material or workmanship defect.
• Appearance/welding defects:The scrap teeth have cracks and over-burning,the weld between the cutter head and the tooth body in not full,and the cutter head falls off. The fullness of the weld of high-quality picks must be ≥99％.
• Dimensional deviation:Key dimensions such as tool handle diameter and circlip groove do not meet the equipment requirments.After installation,the tool cannot rotate or the gap is too large,which accelerates failure.
• Hardness imbalance:The cutter head collapses upon impact or the tooth body is easily bent,which does not meet the "hardness and toughness balance"standard for qualified picks(cutter head HRA 88-91,tooth body HRC 40-48)

(2) Check the working conditions again:if the pick still fails,it may be that your pick is not suitable for the working conditions:

• Insufficient cooling "dry burning"
• The gear seat is damaged and the force is deflected
• Insufficient adaptation to sudden changes in rock formations
• Improper operation and excessive impact

2.Choosing the right pick +adapting to the working conditions is the key to reducing costs! Mailinmate picks solvel the problem of tooth consumption in both directions:

(1)Strict quality control thyoughout the entire process of Mailinmat cutting picks:

• High-quality materials: The tooth body is made of high-strength alloy structural steel,and the cutter head is made of ultra-coarse-grained caibide. Ii has high hardness and toughness to solve the problems of chipping and broken teeth when cutting hard rock.
• Precision technology:CNC machining +precision brazing +isothermal quenching heat treatment,consistent size,weld fill degree≥99％，to avoid eccentric wear and cutter head falling off.
• Fully inspected before leaving the factory :Each batch undergoes multiple inspections on hardness,impact toughness,and appearance,and unqualified products will not enter the market.

(2)Mailinmat launches customized produces to adapt to different strata:

• Special series for hard rock:plasma cladding wear-resistant layer,suitable for F8-F13 grade hard rock and quartz interlayer,the service life is 30％+longer than that of ordinary picks.
• Universal series for all working conditions:optimized tooth shape, suitable for conventional coal seams to complex geology, with high cutting efficiency,low resistance and low energy consumption.

(3)Professional technical services to help you find the root cause of the problem. R&D personnel will help you check the working conditions online,eliminate hidden dangers,and recommend pick models as needed.

3.Conclusion:Spend less money and choose the right pick.

Blindly choosing cheap picks can easily lead to a cycle of "replacement becomes more frequent,and the cost increase".Only by choosing picks with hard quality and strong adaptability such as Mailinmat,and working with standardized operations,can costs be reduced and efficiency improved.
