How to choose equipment for cement packing: experts will help you choose

Those who were dealing with cement before so to say “face to face”, will know about its main peculiarities: it’s dusty and heavy. This complicates the packaging process. Although the issue may be solved easily with assistance of proper equipment. Thanks to the packing machines, cement is packed into small (because it’s heavy) and paper (because it’s dusty) packages. This way you are saving time and protecting the health of employees. In addition, the consumption of the cement itself decreases – the machine packs almost without dust formation outside the package.

The market for packing equipment is now rich in offers. But what to choose from it, let’s figure it out together.

Automation

The easiest way is to navigate in the required level of automation.

There are two categories of packaging machines in this sector:

Automatic
Semiautomatic

Automatic packaging devices perform all the necessary functions without human interference. The speed of their work allows maintaining large-scale production. Semi-automatic units work with the help of the operator, but his participation is slight – to send, turn on, coordinate. They will perfectly fit the workflow with small amounts of output.

Function

Now let’s examine the equipment for cement packing according to its functional tasks:

dispensers (for valve bags)
bags fillers (big bags) and containers
unpackers

Packer dispensers supply the cement into the bags using a rotary thrower.

That is, due to the centrifugal force of the rotor. The dispenser does not require compressed air to fill the packaging, thus it saves the energy and prevents the breakage of the bag due to the pressure. The cement lumps formed during the storage are easily crushed with the same rotor.

The accuracy of weight measurement and the number of bags in the modern models is ensured by the microprocessor controller and the remote control.

Often the unit has a function of dropping the finished products on the strap of the conveyor. The endurance and reliability of dispensers for valve bags allows them to deal with 5-6 tons of cement in one launch.

These machines are easy in maintenance and are sold at an affordable price.

Big bag fillers (large bags) consist of the following units:

raw materials feeder
big bag suspended loop
fan
bunker
dispenser
lifting mechanism
rolling for removal of filled bags
remote control
electric cabinet

There are several types of fillers according to the specifics of production:

for net weighing
for gross weighing
for volumetric weighing

Net-dosing of cement is carried out approximately 2.5 times faster than gross. Volumetric dosing is the fastest, but leads to essential errors. The weight of the material can be significantly changed depending on the method of filling or deformation of bags.

The process of filling the big bag is the following. Power device (screw conveyor, elevator, pump or vibrating feeder) submits the cement to the dispenser. Big bag is being installed at the necessary height, and the fan fills it with air for the most efficient filling. High quality raw material is smoothly submitted to the bag through trays. Some models are equipped with a function of the vibro-shaking and big bag. Thus, the portion of cement is completely transported into the bag. Most of the equipment provides a filter for dust free operation.

Cement unpackers operate in the reverse direction. They open the packed bags and pour cement into containers and other tanks for transportation and further use of cement. Taking into account the bags’ weight that reaches up to 3000 kg, it is challenging to implement this task manually.

The big bag unpacker consists of:

funnel
knife
vibrator (optional)
lifting device (optional)

The sequence of operation is simple. The lifting device delivers a bag to the neck of the unpacker. The knife opens the bottom, and cement is poured into the container, the bunker, etc. through a funnel. For complete feeding, a vibratory shaking is carried out. And in order to avoid dusting there is a function of air intake. As a result, the process is prompt and clean.

The speed of the cement packing equipment depends on the level of capacity and automation. On the average, it’s 300-600 bags per hour.

Based on the above, it is quite possible to determine the necessary set of specifications and features of the packing machine.

Now let’s talk a bit about the quality.

In fact, it is worth talking about it a lot, because high-quality equipment is a direct investment in your profits. It is in your best interest to purchase the equipment which is going to save the time of operation, remuneration of staff and increase the productivity of the enterprise. Therefore, let’s repeat the known truth along with the experts of the “Skladpack” company: trust proven brands.

Only recognized world manufacturers will be able to guarantee you the reliability and long-term operation of the equipment. You will be sure that the dispenser of your packing unit is actually made of stainless steel, and the packer itself is going to be provided with decent maintenance.
