What is a ball press machine?

A ball press machine is a molding device that presses powdered materials into a ball or other shape through mechanical pressure. Ball press machines are mainly used to process powdered materials that are difficult to mold, such as mineral powder, coal powder, coke powder, वगैरह. The ball press machine is characterized by high molding pressure, adjustable main engine speed, and a spiral feeding device. इसलिए, ball press machines are widely used in metallurgy, chemical industry, coal, refractory materials and other industries.

How are ball pressing machines named?

Ball pressing machines are equipment that press powdered materials into balls( briquette machine). Ball pressing machines are usually classified and named according to their purpose, model, or technical characteristics.

Ball pressing machine roller diameter naming

Q290, Q360, Q450, 650, Q750, Q850, Q1000, Q1200.
For example, Q290 has a roller diameter of 290mm. These models are named according to the roller skin diameter.

Ball pressing machines are named according to their purpose

Ball pressing machines can be divided into the following types according to their main uses:

Named according to technical characteristics

Hydraulic briquette machine: uses hydraulic system for pressure regulation and has overpressure protection function.

Strong briquette machine: suitable for materials that are difficult to form, with higher pressure and forming capacity.

The structure of the ordinary ball press machine

The structure of the ball press machine consists of four parts: Feeding part Transmission part Molding part Discharging part

Working principle of ball pressing machine

The ball pressing machine transmits power to the reducer through the motor via the V-belt, and the reducer transmits power to the driving shaft through the coupling to transmit power to the two rollers at the same time, and makes the two rollers rotate in opposite directions. During the rotation of the two rollers, the material enters the ball mold on the roller through the storage bin after quantitative mixing. As the rollers rotate, the pressure on the material increases from small to large. When the material rotates to the line contact point of the two rollers, the pressure on the material reaches the peak. Under the action of the huge line pressure, the material changes from powder to finished ball. After the material passes the line, the molding pressure decreases rapidly, causing the material to enter the ball-off state and smoothly de-ball.

Ball pressing machine processing type

Industrial powder	Mining materials	Metallurgical industry
can be used to press coal powder, iron powder, coking coal, aluminum powder, iron filings, iron oxide, carbon powder, carbon powder, slag, gypsum, sludge, kaolin, activated carbon, coke.	also widely used in the treatment of mineral tailings, pressing difficult-to-form powder materials.	waste materials and auxiliary materials that need to be put into the furnace need to be completed by the ball pressing machine. For example: dust removal ash, pond mud, oxide scale, steel slag, iron concentrate powder, aluminum ash powder, silicon manganese ore powder, वगैरह.

Ball press shape

The mold/roller determines the shape of the ball and is the main vulnerable part. The material is 65Mn. If you have special requirements for the material, we can customize it, such as 9Cr2Mo.

Ball press machine ball size

The ball size is usually expressed by 2 or 3 data, such as the diameter and thickness of the common spherical round (oblate): 50*30मिमी (diameter 50mm, thickness 30mm)

Common shapes are: round (oblate) (50*30मिमी), pillow (60*40*20), bread (40*60*25मिमी). The smaller the ball press model, the smaller the minimum size of the ball. Q290, Q360 ball press can be made into a minimum diameter of 25mm, if you want a smaller or special size, you need to confirm. If the size is small, it will affect demolding.

If you have special needs, such as a logo on the press ball, वगैरह।, स्मैट मशीनरी will design the corresponding mold according to your needs.

What are the 3 types of ball press machines?

Classification according to the functional configuration of the ball press machine. It can be divided into:

1.strong ball press machine (ordinary ball press machine),

2.hydraulic ball press machine,

3.dry powder ball press machine.

Ordinary ball press machine

Strong ball press machine, also known as ordinary ball press machine.It is the most common, commonly used and most recommended to customers. It has a wide range of applications,
cheap price, durable, high market recognition, and a broad market base.

Hydraulic Ball Press Machine

If you have strict requirements on strength? Choosing a hydraulic ball press will be your best choice.
The ball press machine adopts a unique hydraulic system (a hydraulic device is installed behind the passive bearing seat), which effectively enhances the ball forming rate and ball forming strength.

Hydraulic briquette machine is suitable for wet powder ball pressing, that is, it is necessary to add an appropriate amount of water and other adhesives to the material. It has a good effect on the pressing of various materials, such as lightly burned magnesium powder, iron oxide, silicon manganese alloy, sludge, desulfurized gypsum, activated carbon, silicon carbide, copper concentrate, iron concentrate and various refractory materials.

Equipped with a hydraulic overload protection buffer device, it can better protect the equipment from the impact of hard objects. .

Adjust the roller pressure. The hydraulic ball press can adjust the pressure according to the requirements of the ball density, making the production more flexible.

Dry Powder Ball Press Machine

If you need to have no adhesive? Then the dry powder ball press will be your best choice.

The dry powder ball press equipment is mainly used for ball pressing and agglomeration of materials without water. Such as: quicklime powder, magnesium oxide powder, copper concentrate, chromium ore powder, lead and zinc waste, bauxite, non-ferrous metal powder, refractory materials, ceramic materials, वगैरह. are made into finished balls with higher capacity through high strength and high pressure.

The dry powder ball press has the remarkable characteristics of high strength, good toughness and good wear resistance. The dry powder ball press is widely used in metallurgy, chemical industry, refractory materials and other industries.

3 things you need to know about operating a ball pressing machine

Ball press feed requirements (the material is preferably a mixture of powder and granules):
Material size: <5-8मिमी

The moisture and adhesive ratio of the briquette machine material are as follows:

Moisture: 10%-15%
Adhesive (commonly used starch): 3%-5%
Material powder and granules: 80%-85%

Types of common adhesives:

Common adhesives: starch (starch needs to be added with boiling water), water glass, dry powder adhesive
Other adhesives: sodium silicate, bentonite, clay, corn starch.

Ball press machine workflow

The workflow of the ball press machine mainly includes material preparation, feeding, molding, और निर्वहन

Material preparation → Material pretreatment → Material mixing → Feeding device → Ball press machine inlet → Roller molding → Demolding → Discharging device → Subsequent processing (drying, स्क्रीनिंग, packaging)

Importance of ball press

Why do we need briquette machine? More than 10 billion tons of coal are consumed worldwide every year in the form of combustion alone. Raw coal is directly used for combustion without washing, which not only wastes energy, but also produces a large amount of coal smoke and greenhouse gas emissions. The use of clean coal technology is the best choice to improve coal utilization efficiency and reduce pollution.

By adding additives to the pulverized coal for kneading and molding, it is used as fuel for industrial boilers and kilns. Compared with the direct combustion of loose coal, the smoke emission can be reduced by 60%, and the SO2 emission can be reduced by 50%. The briquette machine is undoubtedly the best pulverized coal molding equipment.

The briquette machine is mainly used for the balling and agglomeration of non-ferrous and ferrous metal ore powders, which are directly put into the furnace for smelting to increase the added value. All waste materials and auxiliary materials in the metallurgical industry that need to be put into the furnace need to be completed by the briquette machine. All waste materials and auxiliary materials in the metallurgical industry that need to be put into the furnace need to be completed by the briquette machine.

For example: dust removal ash, pool mud, oxide scale, steel slag, iron ore powder, aluminum ash powder, silicon manganese ore powder, वगैरह. Various powders (such as magnesia, bauxite, dolomite, iron powder, वगैरह।) can be forced to increase pressure, pre-pressed spiral precision processing, and made into high-density ball blanks, which are widely used in metallurgy, chemical industry, coal and refractory materials industries.

The materials formed by the ball press are energy-saving and environmentally friendly, easy to transport, and improve the utilization rate of waste materials, with good economic and social benefits.
