PELLET MILL CLM 630 XPERIENCE

PRESS CLM 630 XPERIENCE with built-in application is the new machine from La Meccanica. With the LM Gate app, you can perform some important actions such as downloading technical materials, real-time monitoring, quickly ordering parts and much more.

The 630 units are our most common pellet press model due to their robust design and minimal maintenance and machine downtime.
Now the series has been expanded with the XPERIENCE model, equipped with:
- more compact form and elegant design,
- reduced surface, which reduces dust ingress and makes cleaning easier,
- more accessible inspection doors for scheduled and unscheduled maintenance,
- new thermal insulation of the air conditioner and heating plates, which guarantees energy savings and high thermal inertia,

Optional

WAP remote roller adjustment

The rollers are adjusted by a hydraulic piston driven by a hydraulic device located outside the machine and controlled from the control panel.

The position of the rollers is calculated by means of an angular potentiometer mounted behind the rollers (inside the main shaft). The potentiometer signals the angular position of the roller pins. By operating the entire system from the control panel, the distance between the rollers and the die can be calculated using the signal transmitted by the potentiometer.

At the electronic panel, the operator chooses the roller position. The panel pressurizes the hydraulic circuit and moves the piston until the rollers reach the desired position.

From the electrical panel, the operator determines the position of the rollers by applying pressure to the hydraulic system and moving the piston until the rollers reach the desired position. Once the desired position has been reached, the system is locked and held in position by two valves.

The maximum pressure reached by the hydraulic system is 250 bar, and the required pressure for moving the piston and adjusting the rollers is 150 bar.

The adjustment is done quite quickly: you can move the rollers closer or further away from the matrix by 7-8 mm, in each direction in about 15 seconds.

RAPID BLOC quick die change system

rapid bloc quick device for change dies.jpg

The device allows replacing the matrix in 10-20 minutes, depending on its size. The system includes a tapered stainless steel ring that is closed and held in place by Belleville disc springs.

This ring locks the die in place. The matrix is released by pressure on the hydraulic system, which pushes the springs to release the elastic ring.

For more information, watch the following video: Rapid Block System

Hydraulic die extraction system

hydraulic push off devices.jpg

The system consists of a hand pump and a piston, which are needed to dismantle the die.

The piston is installed between the rotor and the reinforcement flange so as to push the die out of its seat.

Automatic lubrication

This system includes a high viscosity grease pump.

It is equipped with blades to break up possible air bubbles. The system is connected to the press via a rotary distributor connected directly to the main shaft.

Lubrication is controlled by an electrical panel that is included in the delivery. The panel allows you to measure the required amount of grease using two timers to regulate the time for applying grease and pause.

The pump has the following characteristics:

● the flow is adjustable from 2.9 to 17 cc / min.

● motor 0.185 kW, 400V, 50Hz

● steel tank for 10 kg

● filter

● pressure relief valve

● pressure gauge

● indicator of minimum lubricant level

● progressive dispenser for distributing grease at two points

● inductive PNP sensor for cycle monitoring

● control valves for 1/8 outlet

Thermal insulation

Thermal insulation

It is very useful in countries with cold climates or when there is a large temperature difference between day and night. Prevents condensation and crust formation in the air conditioner.

In order to improve the conditioning of flour at high temperatures, the air conditioner unit can be equipped with an external heater that uses low pressure steam to heat the diathermic oil. The system includes insulation that improves thermal efficiency and prevents condensation.

This system has significant advantages over traditional steam heating:

• has significant thermal inertia

higher temperatures can be reached

Heating the air conditioner with oil

• uniform temperature distribution along the entire length of the machine

in a traditional steam heating system there is a risk of breakage and steam escaping from the coupling due to internal pressure

Heating the main door

Electric heating of the main door prevents crusting

Blockage sensor for front convector

emergency level probe of front conveyor.jpg

Especially in the case of formulas containing oil, the pellet press is often subject to “wet clogging”. It occurs when the die begins to slide and throw off the product without overloading the main motor, which only detects current fluctuations. In a few seconds, complete clogging of the bale chamber and convector is obtained.

In this case, the clogging sensor signals an anomaly and allows you to stop the press without serious consequences.

Front by-pass for flour

front bypass for meal.jpg

For some product lines, it is necessary to bypass the press by sending flour directly to the cooler. The pellet press can be equipped with a hydraulic piston controlled bypass installed in the front dispenser.

Automatic cleaning of the temperature probe

automatic cleaning of the temperature probe.jpg

The temperature probe gradually becomes covered with layers of damp flour, which can increase the reading time and, as a result, reactions. This affects the effectiveness of the process control system, which is based on temperature readings. The automatic probe cleaning system solves this problem. It is a mechanical device that automatically cleans the temperature probe when material starts to accumulate on it.

IFM electronic belt slip control

This electronic device shuts off the engine when the belts begin to slip, thus preventing damage to the belts themselves.

Slow rotation of the matrix

Hand winch

The hand winch is an alternative to the hydraulic lift. On request, the pellet mill can be equipped with a hand winch and special anchor hooks that facilitate the assembly and disassembly of dies and rollers.

hydraulic lifter for rollers and die

The practical hydraulic lift is equipped with special hooks to facilitate the movement of the dies and rollers, especially during assembly and disassembly. This lifter allows you to easily and safely move dies and shells in the work area.

Lamec control system lcs 2000 FV

lamec control system.jpg lamec control system-2.jpg

The LCS FV 2000 control system is an electrical panel with Siemens PLC that controls the automation of the press through two coordinated processes.

The first process adjusts the performance of the feed auger depending on the power consumed by the main motor. In particular, the system monitors the speed of the auger and acts on the frequency converter.

The second process regulates the flow of steam admitted to the conditioner depending on the conditioning temperature of the flour when the motorized steam valve is opened or closed.

The control panel is equipped with a display and a keypad for data entry.

The system is not complicated and does not require specialized personnel.

At the same time, the motorized steam valve opens and adjusts to the desired air temperature.

In the event of an emergency, the system acts on the emergency door of the conveyor to avoid overloading: product flow and steam flow are reduced simultaneously.

As soon as there is no more risk of overloading, the auger speed is gradually restored to normal values depending on the load of the main motor, and the steam flow is brought back to normal values.

At the end of the process, the device gradually decreases the screw speed and progressively closes the steam valve.

The system includes:

• electronic control panel for lcs pv complete with PLC SIEMENS SERIES 7

• wattmeter

• CAM LOGIC level indicator

• counter

• temperature probe PT 100

• probe holder

• valves for regulating the steam flow

ON / OFF valve for steam regulation

Personalization

Our goal is to supply all our customers with pellet presses that meet their needs. For this reason, all our models can be personalized: the client can choose the position of the engine, the side of the hatch opening, the size and volume of the air conditioner, the size of the auger, the color, etc.
